Guide for International Peer Reviews of Decommissioning Cost Studies for Nuclear Facilities
English, 49 pages, published: 10/27/14
NEA#7190
Available online at: http://www.oecd-nea.org/rwm/pubs/2014/7190-guide-peer-reviews.pdf
Peer reviews are a standard co-operative OECD working tool that offer member countries a framework to compare experiences and examine best practices in a host of areas. The OECD Nuclear Energy Agency (NEA) has developed a proven methodology for conducting peer reviews in radioactive waste management and nuclear R&D. Using this methodology, the NEA Radioactive Waste Management Committee’s Working Party on Decommissioning and Dismantling (WPDD) developed the present guide as a framework for decommissioning cost reviewers and reviewees to prepare for and conduct international peer reviews of decommissioning cost estimate studies for nuclear facilities. It includes checklists that will help national programmes or relevant organisations to assess and improve decommissioning cost estimate practices in the future. This guide will act as the NEA reference for conducting such international peer reviews.

- Français: L'extraction d'uranium aujourd'hui : perceptions et réalités – Résumé détaillé 
Uranium mining and milling has evolved significantly over the years. By comparing currently leading approaches with outdated practices, this report demonstrates how uranium mining can be conducted in a way that protects workers, the public and the environment. Innovative, modern mining practices combined with strictly enforced regulatory standards are geared towards avoiding past mistakes committed primarily during the early history of the industry when maximising uranium production was the principal operating consideration. Today?s leading practices in uranium mining aim at producing uranium in an efficient and safe manner that limits environmental impacts to acceptable standards. As indicated in this report, the collection of baseline environmental data, environmental monitoring and public consultation throughout the life cycle of the mine enables verification that the facility is operating as planned, provides early warning of any potentially adverse impacts on the environment and keeps stakeholders informed of developments. Leading practice also supports planning for mine closure before mine production is licensed to ensure that the mining lease area is returned to an environmentally acceptable condition. The report highlights the importance of mine workers being properly trained and well equipped, as well as that of ensuring that their work environment is well ventilated so as to curtail exposure to radiation and hazardous materials and thereby minimise health impacts.

Nuclear Energy Data is the OECD Nuclear Energy Agency's annual compilation of statistics and country reports documenting the status of nuclear power in the OECD area. Information provided by member country governments includes statistics on installed generating capacity, total electricity produced by all sources and by nuclear power, nuclear energy policies and fuel cycle developments, as well as projected generating capacity and electricity production to 2035, where available. Total electricity generation at nuclear power plants and the share of electricity production from nuclear power plants remained steady in 2013 despite the progressive shutdown of all reactors in Japan leading up to September and the permanent closure of six reactors in the OECD area. Governments committed to maintaining nuclear power in the energy mix advanced plans for increasing nuclear generating capacity, and progress was made in the development of deep geological repositories for spent nuclear fuel, with Finland expected to have the first such facility in operation in the early 2020s. Further details on these and other developments are provided in the publication's numerous tables, graphs and country reports.

NEA#7192
Available online at: http://www.oecd-nea.org/rwm/pubs/2014/7192-cpd-report.pdf
Decommissioning of nuclear facilities and related remedial actions are currently being undertaken around the world to enable sites or parts of sites to be reused for other purposes. Remediation has generally been considered as the last step in a sequence of decommissioning steps, but the values of prevention, long-term planning and parallel remediation are increasingly being recognised as important steps in the process. This report, prepared by the Task Group on Nuclear Site Restoration of the NEA Co-operative Programme on Decommissioning, highlights lessons learnt from remediation experiences of NEA member countries that may be particularly helpful to practitioners of nuclear site remediation, regulators and site operators. It provides observations and recommendations to consider in the development of strategies and plans for efficient nuclear site remediation that ensures protection of workers and the environment.

State-of-the-art Report on Innovative Fuels for Advanced Nuclear Systems
English, 193 pages, published: 12/12/14
NEA#6895
Available online at: http://www.oecd-nea.org/science/pubs/2014/6895-report-innovative-fuels.pdf
Development of innovative fuels such as homogeneous and heterogeneous fuels, ADS fuels, and oxide, metal, nitride and carbide fuels is an important stage in the implementation process of advanced nuclear systems. Several national and international R&D programmes are investigating minor actinide-bearing fuels due to their ability to help reduce the radiotoxicity of spent fuel and therefore decrease the burden on geological repositories. Minor actinides can be converted into a suitable fuel form for irradiation in reactor systems where they are transmuted into fission products with a significantly shorter half-life.

This report compares recent studies of fuels containing minor actinides for use in advanced nuclear systems. The studies review different fuels for several types of advanced reactors by examining various technical issues associated with fabrication, characterisation, irradiation performance, design and safety criteria, as well as technical maturity.

The Characteristics of an Effective Nuclear Regulator
NEA/CNRA/R(2014)1
English, 32 pages, published: 07/04/14
NEA#7185
Available online at: http://www.oecd-nea.org/nsd/pubs/2014/7185-regulator.pdf
Both national and international organisations agree that the fundamental objective of all nuclear safety regulatory bodies -- the regulator's prime purpose -- is to ensure that nuclear licensees operate their facilities at all times in a safe manner. Much has been written about ways to improve regulatory processes or to improve the effectiveness of a regulatory body, including in previous OECD/NEA regulatory guidance booklets. But until now, none have focused on the characteristics of an effective nuclear safety regulator.

Effective organisations are those that have good leadership and are able to transform strategic direction into operational programmes. Effectiveness is about how well the organisation is achieving its fundamental purpose -- in the case of a nuclear safety regulator, ensuring that licensees operate their facilities and discharge their obligations in a safe manner.

This regulatory guidance booklet describes the characteristics of an effective nuclear safety regulator in terms of roles and responsibilities, principles and attributes. Each of the characteristics discussed in this report is a necessary feature of an effective nuclear safety regulator but no one characteristic is sufficient on its own. It is the combination of these characteristics that leads to the effectiveness of a nuclear regulatory body. The report provides a unique resource to countries with existing, mature regulators and can be used for benchmarking as well as training and developing staff. It will also be useful for new entrant countries in the process of developing and maintaining an effective nuclear safety regulator.

Other language(s):
- English: Uranium 2014: Resources, Production and Demand - Executive Summary
- Français: Uranium 2014 : Ressources, production et demande - Synthèse 
Uranium is the raw material used to fuel over 400 operational nuclear reactors around the world that produce large amounts of electricity and benefit from life cycle carbon emissions as low as renewable energy sources. Although a valuable commodity, declining market prices for uranium since the Fukushima Daiichi nuclear power plant accident in 2011, driven by uncertainties concerning the future of nuclear power, have led to the postponement of mine development plans in a number of countries and raised questions about continued uranium supply. This 25th edition of the "Red Book", a recognised world reference on uranium jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, provides analyses and information from 45 producing and consuming countries in order to address these and other questions. It includes data on global uranium exploration, resources, production and reactor-related requirements. It offers updated information on established uranium production centres and mine development plans, as well as projections of nuclear generating capacity and reactor-related requirements through 2035, incorporating policy changes following the Fukushima accident, in order to address long-term uranium supply and demand issues.

CSNI Technical Opinion Papers No. 16
Defence in Depth of Electrical Systems
English, 48 pages, published: 05/17/13
NEA#7070
Available online at: http://www.oecd-nea.org/nsd/docs/2013/7070-top-16.pdf
As all safety systems in the majority of existing nuclear power plants use the preferred power supply, any voltage surges in these systems could lead to common-cause failures. In the event of an unusual electrical system transient, it is essential that safety-related equipment be isolated or protected from the fault in order to ensure its ability to safely shut down the reactor and remove decay heat.
Based on the analysis of the voltage surges observed at Forsmark-1 in 2006 and Olkiluoto-1 in 2008, this technical opinion paper summarises the current state of knowledge of in-plant and external grid-related challenges to nuclear power plant safety-related electrical equipment. It will be of particular interest to nuclear safety regulators, nuclear power plant operators and grid system regulators and operators.

Crisis Communication: Facing the Challenges - Proceedings
Workshop Proceedings, Madrid, Spain, 9-10 May 2012
English, 240 pages, published: 05/06/13
NEA#7067
Available online at: http://www.oecd-nea.org/nsd/docs/2013/7067-crisis-communication.pdf
As manifested by an increasingly globalised media, a nuclear accident anywhere quickly becomes a potential concern for people everywhere. It is therefore of prime importance that nuclear regulators’ communication strategies take into consideration the expectations and concerns of the public and provide sound information not only for the people of the affected country, but also for citizens worldwide. Public trust is a key element in being able to do so effectively and of particular importance when there are consequences for people or the environment. International co-operation can play a fundamental role in helping to improve crisis communication on national and global scales in the event of a nuclear accident or radiological emergency. These proceedings contain the papers, recommendations and conclusions of the workshop, which was attended by over 180 experts from 27 countries and 6 international organisations.

International Handbook of Evaluated Reactor Physics Benchmark Experiments (DVD)
March 2013
English, published: 05/13/13
NEA#7140
Available online at: http://www.oecd-nea.org/science/wprs/irphe/irphe-handbook/
The International Reactor Physics Experiments Evaluation Project (IRPhEP) was launched in 1999 by the Organisation for Economic Co-operation and Development (OECD) Nuclear Energy Agency (NEA) Nuclear Science Committee (NSC). While co-ordination and administration of the IRPhEP is managed at the international level by the NEA, each participating country is responsible for the administration, technical direction and priorities of the project within their respective countries. The information and data included in this handbook are available to NEA member countries, to all contributing countries and to others on a case-by-case basis.
This handbook contains reactor physics benchmark specifications that have been derived from experiments performed at various nuclear facilities around the world. The benchmark specifications are intended for use by reactor designers, safety analysts and nuclear data evaluators to validate calculation techniques and data. Example calculations are presented; they do not, however, constitute validation or endorsement of the codes or cross-section data.
The 2013 edition of the International Handbook of Evaluated Reactor Physics Benchmark Experiments contains data from 130 experimental series performed at 47 reactor facilities. One hundred twenty-six of the 130 evaluations are published as approved benchmarks; the remaining four are published as draft documents only.
New to the handbook are benchmark specifications for selected measurements on the very-high-temperature reactor critical assembly (VHTRC) which were performed at the Japan Atomic Energy Agency (JAEA) Tokai Research Establishment in Japan between 1985 and 1996.

Nuclear Energy Data is the OECD Nuclear Energy Agency's annual compilation of statistics and country reports documenting the status of nuclear power in the OECD area. Information provided by member country governments includes statistics on installed generating capacity, total electricity produced by all sources and by nuclear power, nuclear energy policies and fuel cycle developments, as well as projected generating capacity and electricity production to 2035, where available. Total electricity generation at nuclear power plants and the share of electricity production from nuclear power plants declined in 2012 as a result of operational issues at some facilities and suspended operation at all but two reactors in Japan. Nuclear safety was further strengthened in 2012 following safety reviews prompted by the Fukushima Daiichi nuclear power plant accident. Governments committed to maintaining nuclear power in the energy mix pursued initiatives to increase nuclear generating capacity. In Turkey, plans were finalised for the construction of the first four reactors for commercial electricity production. Further details on these and other developments are provided in the publication's numerous tables, graphs and country reports.

Particle accelerators have evolved over the last decades from simple devices to powerful machines, and are having an increasingly important impact on research, technology and daily life. Today they have a wide range of applications in many areas including material science and medical applications. In recent years, new technological and research applications have helped to define requirements while the number of accelerator facilities in operation, being commissioned, designed or planned has grown significantly. Their parameters, which include the beam energy, currents and intensities, and target composition, can vary widely, giving rise to new radiation shielding aspects and problems.
Particle accelerators must be operated in safe ways to protect operators, the public and the environment. As the design and use of these facilities evolve, so must the analytical methods used in the safety analyses. These workshop proceedings review the state of the art in radiation shielding of accelerator facilities and irradiation targets. They also evaluate progress in the development of modelling methods used to assess the effectiveness of such shielding as part of safety analyses.

NEA#6409
Available online at: http://www.oecd-nea.org/science/pubs/2013/6409-sr-smans.pdf
Materials performance is critical to the safe and economic operation of any nuclear system. As the international community pursues the development of Generation IV reactor concepts and accelerator-driven transmutation systems, it will be increasingly necessary to develop advanced materials capable of tolerating the more challenging environments of these new systems. The international community supports numerous materials research programmes, with each country determining its individual focus on a case-by-case basis. In many instances, similar alloys of materials systems are being studied in several countries, providing the opportunity for collaborative and cross-cutting research that benefits different systems.

This report is a snapshot of the current materials programmes supporting the development of advanced concepts. The descriptions of the research are grouped by concept, and national programmes are described within each concept. The report provides an overall sense of the importance of materials research worldwide and the opportunities for synergy among the countries represented in this overview.

The International Nuclear Emergency Exercise (INEX) series, organised under the OECD Nuclear Energy Agency (NEA) Working Party on Nuclear Emergency Matters (WPNEM), has proven successful in testing, investigating and improving national and international response arrangements for nuclear accidents and radiological emergencies. Early INEX exercises focused on the national and international aspects of early phase management of nuclear power plant emergencies. Starting with INEX-3 (2005-2006), the international community began looking at issues concerning longer-term consequence management. In 2008, the WPNEM started preparing the INEX-4 series, which was conducted in 2010-2011 and addressed consequence management and transition to recovery in response to malicious acts involving the release of radioactive materials in an urban setting. The goal of INEX-4 was to provide a basis for enhancing emergency management through the exchange of exercise experiences from participating countries and the identification of good practices and common issues. This summary report provides general outcomes based on country responses to the INEX-4 evaluation questionnaire and suggests areas of focus for future consideration.

- Français: Economie de l'aval du cycle du combustible nucléaire - Synthèse 
The feasibility and costs of spent nuclear fuel management and the consequent disposal of ultimate waste continue to be the subject of public debate in many countries, with particular concern often expressed over the lack of progress in implementing final disposal. Uncertainties about back-end costs and the financial risks associated with management of the back end have also been singled out as possible deterrents to investment in new nuclear power plants.

This report offers an appraisal of economic issues and methodologies for the management of spent nuclear fuel and high-level waste from commercial power reactors. It includes a review of different back-end options and current policies and practices, with a focus on the cost estimates for these options and the funding mechanisms in place or under consideration in OECD/NEA countries. A generic economic assessment of high-level estimates of back-end cost impacts on fuel cycle costs is undertaken for selected idealised scenarios, by means of a simple static model. Sensitivity analyses are conducted for the evaluation of uncertainties in major components and the identification of cost drivers. Since factors other than economics are an important part of the decision-making process, an analysis of the influence of key qualitative parameters in the selection of back-end strategies is also presented in this report.

Future fuel cycle characteristics, feasibility and acceptability will be crucial for the continued development of nuclear energy, especially in the post-Fukushima context. Fuel cycle choices have both long- and short-term impacts, and a holistic assessment of their characteristics, cost and associated safety issues is of paramount importance. This report seeks to associate quantified impacts with foreseeable nuclear energy development in different world regions. It gives initial results in terms of uranium resource availability, fuel cycle facility deployment and reactor types. In particular, the need to achieve short doubling times with future fast reactors is investigated and quantified. The report also provides guidelines for performing future studies to account for a wider range of hypotheses on energy demand growth, different hypotheses regarding uranium resource availability and different types of reactors to be deployed.

The Joint Evaluated Fission and Fusion (JEFF) Project is a collaborative effort among OECD Nuclear Energy Agency (NEA) Data Bank member countries to develop a reference nuclear data library for use in different energy applications. These data can be used to help improve the safety and economy of existing installations, as well as to design advanced nuclear reactors and their associated fuel cycles, including radioactive waste management. The JEFF-3.1 library contains several different data types, including neutron and proton interaction data, neutron activation data, radioactive decay data, fission yield data and thermal scattering data. This report describes the initial validation of the complete JEFF-3.1 library for thermal reactors, fuel cycle, storage and reprocessing, fusion technology and intermediate energy applications. It will be useful for scientists and engineers in national laboratories, universities and industry who use basic nuclear data, and is particularly suitable for those who work with application libraries based on JEFF-3.1.

Burn-up Credit Criticality Safety Benchmark – Phase VII
UO2 Fuel: Study of Spent Fuel Compositions for Long-term Disposal
English, 180 pages, published: 02/21/12

After spent nuclear fuel (SNF) is discharged from a nuclear reactor, fuel composition and reactivity continue to vary as a function of time due to the decay of unstable nuclides. Accurate predictions of the concentrations of long-lived radionuclides in SNF, which represent a significant potential hazard to human beings and to the environment over a very long period, are particularly necessary for radiological dose assessments.
This report assesses the ability of existing computer codes and associated nuclear data to predict isotopic compositions and their corresponding neutron multiplication factor (keff) values for pressurised-water-reactor (PWR) UO2 fuel at 50 GWd/MTU burn-up in a generic spent fuel cask configuration. Fuel decay compositions and keff values have been calculated for 30 post-irradiation time steps out to one million years.

The way in which nuclear licensees’ organisations are structured and resourced clearly has a potential impact on nuclear safety. As experience has continually demonstrated, operating organisations with a strong training programme for personnel, adequate resourcing and overall effective leadership and management perform more effectively in times of crisis than those lacking in one or more of these areas. In parallel, the nuclear industry is developing new resource deployment strategies which are making increased use of contractors and leading to changes in organisational structure, which in turn create challenges for the continued safe operation of nuclear facilities. This technical opinion paper represents the consensus among human and organisational factor specialists in NEA member and associated countries on the methods, approaches and good practices to be followed in designing an organisation with a strong safety focus while meeting business needs. It also considers some of the attributes that an organisation which is effectively managing its resources and capabilities might demonstrate.

- Français: Défis de l'exploitation à long terme des centrales nucléaires 
Nuclear power reactors have become a major source of electricity supply in many countries and, based on the experience of safe and reliable operation, many operators have sought and received authorisation for long-term operation beyond the period assumed in the plant’s design. Acceptance of a nuclear power plant for long-term operation must be based on evidence that the plant will operate safely over the extended period of service. This requires an assessment of the current and projected condition of the plant and, in particular, of the systems that perform fundamental safety functions, to ensure that these systems will continue to perform their safety functions during the extended operating period. Programmes for long-term operation must be informed by operating experience and must also consider and assess environmental impacts.
This guidance document is intended to assist regulatory organisations in assessing and approving the long-term operation safety assessments submitted by operators. It outlines the fundamental principles that should govern decisions on authorisation for long-term operation. It also describes regulatory challenges and considerations that may arise in an assessment of a plant for long-term operation.

- Français: Stockage géologique des déchets radioactifs : Engagement national, participation locale et régionale 
Disposal in engineered facilities built in stable, deep geological formations is the reference solution for permanently isolating long-lived radioactive waste from the human biosphere. This management method is designed to be intrinsically safe and final, meaning that it is not dependent on human presence or intervention in order to fulfil its safety goal. Selecting the site of a waste repository brings up a range of issues involving scientific knowledge, technical capacity, ethical values, territorial planning, community well-being and more. Bringing to fruition the multi-decade task of siting and developing a repository demands a strong national commitment and significant regional and local involvement.
This collective statement by the Radioactive Waste Management Committee of the OECD Nuclear Energy Agency recognises the advances made towards greater transparency and dialogue among the diverse stakeholders concerned and identifies the fundamental elements needed to support national commitment and to foster territorial involvement. It concludes that technical and societal partners can develop shared confidence in the safety of geological repositories and jointly carry these projects forward.

Homogeneous versus Heterogeneous Recycling of Transuranics in Fast Nuclear Reactors
English, 92 pages, published: 12/31/12
NEA#7077, ISBN: 978-92-64-99177-4
Available online at: http://www.oecd-nea.org/science/docs/2012/7077-hvh-recycling-transuranics-fnr.pdf
Fuel transuranics (TRU) multi-recycling is a mandatory feature if both the resource sustainability and the waste minimisation objectives for future fuel cycles are to be pursued. The resulting TRU transmutation can be implemented in fast neutron spectrum reactors according to two main options commonly referred to as the homogeneous and heterogeneous modes.

In this study, the two alternatives have been compared in terms of reactor core feasibility, fuel development and impact on the fuel cycle. The multi-criteria analysis indicates that there are major challenges in minor actinide-loaded fuel development, its experimental validation and possibly in its reprocessing. Both modes of recycling have an impact on the overall fuel cycle, even if at different stages, for example complex target fabrication and handling in the case of heterogeneous recycling and full core fuel fabrication in the case of homogeneous recycling. The study finds that an economic evaluation according to specific implementation scenarios should still be undertaken.

The International Criticality Safety Benchmark Evaluation Project (ICSBEP), originally initiated at the national level by the US Department of Energy in 1992, became an official activity of the Organisation for Economic Co-operation and Development (OECD) Nuclear Energy Agency (NEA) in 1995.

This handbook contains criticality safety benchmark specifications that have been derived from experiments performed at various critical facilities around the world. The benchmark specifications are intended for use by criticality safety engineers to validate calculation techniques used to establish minimum subcritical margins for operations with fissile material and to determine criticality alarm requirement and placement. Many of the specifications are also useful for nuclear data testing. Example calculations are presented; these calculations do not, however, constitute a validation of the codes or cross-section data.

The evaluated criticality safety benchmark data are presented in nine volumes, containing over 58 000 pages and 533 evaluations with benchmark specifications for 4 552 critical, near-critical or subcritical configurations, 24 criticality alarm placement/shielding configurations with multiple dose points for each, and 200 configurations that have been categorised as fundamental physics measurements that are relevant to criticality safety applications.

New to the handbook are benchmark specifications for the GROTESQUE: Complex Geometric Arrangement of Unreflected HEU (93.15) Metal Pieces experiment (see front cover) that was performed by John T. Mihalczo at the Oak Ridge National Laboratory Critical Experiment Facility in June 1964.

The International Reactor Physics Experiments Evaluation Project (IRPhEP) was launched in 1999 by the Organisation for Economic Co-operation and Development (OECD) Nuclear Energy Agency (NEA) Nuclear Science Committee (NSC). While co-ordination and administration of the IRPhEP is managed at the international level by the NEA, each participating country is responsible for the administration, technical direction and priorities of the project within their respective countries. The information and data included in this handbook are available to NEA member countries, to all contributing countries and to others on a case-by-case basis.

This handbook contains reactor physics benchmark specifications that have been derived from experiments performed at various nuclear facilities around the world. The benchmark specifications are intended for use by reactor designers, safety analysts and nuclear data evaluators to validate calculation techniques and data. Example calculations are presented; they do not, however, constitute validation or endorsement of the codes or cross-section data.

The 2012 edition of the International Handbook of Evaluated Reactor Physics Benchmark Experiments contains data from 56 experimental series performed at 32 reactor facilities. Fifty-four of the 56 evaluations are published as approved benchmarks; the remaining two are published as draft documents only.

New to the handbook are benchmark specifications for selected configurations from the HTR-PROTEUS Pebble Bed Experimental Program which were performed at the Paul Scherrer Institute’s PROTEUS zero-power research reactor in Villigen, Switzerland between 1992 and 1996.

International Structure for Decommissioning Costing (ISDC) of Nuclear Installations
English, 192 pages, published: 03/02/12
NEA#7088, ISBN: 978-92-64-99173-6
Available online at: http://www.oecd-nea.org/rwm/reports/2012/ISDC-nuclear-installations.pdf
Cost estimation for the decommissioning of nuclear facilities can vary considerably in format, content and practice both within and across countries. These differences may have legitimate reasons but make the process of reviewing estimates complicated and the estimates themselves difficult to defend. Hence, the joint initiative of the OECD Nuclear Energy Agency (NEA), the International Atomic Energy Agency (IAEA) and the European Commission (EC) was undertaken to propose a standard itemisation of decommissioning costs either directly for the production of cost estimates or for mapping estimates onto a standard, common structure for purposes of comparison. This report updates the earlier itemisation published in 1999 and takes into account experience accumulated thus far. The revised cost itemisation structure has sought to ensure that all costs within the planned scope of a decommissioning project may be reflected. The report also provides general guidance on developing a decommissioning cost estimate, including detailed advice on using the structure.

Main Benefits from 30 Years of Joint Projects in Nuclear Safety
English, 132 pages, published: 05/04/12
NEA#7073, ISBN: 978-92-64-99171-2
Available online at: http://www.oecd-nea.org/nsd/reports/2012/nea7073-30-years-joint-safety-projects.pdf
One of the major achievements of the OECD Nuclear Energy Agency (NEA) is the knowledge it has helped to generate through the organisation of joint international research projects. Such projects, primarily in the areas of nuclear safety and radioactive waste management, enable interested countries, on a cost-sharing basis, to pursue research or the sharing of data with respect to particular areas or issues. Over the years, more than 30 joint projects have been conducted with wide participation of member countries.
The purpose of this report is to describe the achievements of the OECD/NEA joint projects on nuclear safety research that have been carried out over the past three decades, with a particular focus on thermal-hydraulics, fuel behaviour and severe accidents. It shows that the resolution of specific safety issues in these areas has greatly benefited from the joint projects’ activities and results. It also highlights the added value of international co-operation for maintaining unique experimental infrastructure, preserving skills and generating new knowledge.

Safety assessment is an interdisciplinary approach that focuses on the scientific understanding and performance assessment of safety functions as well as the hazards associated with a geological disposal facility. It forms a central part of the safety case, and the results of the safety assessments provide evidence to support decision making. The goals of the NEA project on “Methods for Safety Assessment for Geological Disposal Facilities for Radioactive Waste” (MeSA) were to examine and document methods used in safety assessment for radioactive waste disposal facilities, to generate collective views based on the methods’ similarities and differences, and to identify future work. The project reviewed a number of approaches used by various national and international organisations. Following the comprehensive review, a generic safety case with a safety assessment flowchart was developed and is presented herein. The elaboration of the safety concept, the use of safety functions, the implication of uncertainties and the formulation of scenarios are also discussed.

Available online at: http://www.oecd-nea.org/ndd/pubs/2012/6979-nuclear-education.pdf
The OECD Nuclear Energy Agency (NEA) first published in 2000 Nuclear Education and Training: Cause for Concern?, which highlighted significant issues in the availability of human resources for the nuclear industry. Ten years on, Nuclear Education and Training: From Concern to Capability considers what has changed in that time and finds that, while some countries have taken positive actions, in a number of others human resources could soon be facing serious challenges in coping with existing and potential new nuclear facilities. This is exacerbated by the increasing rate of retirement as the workforce ages. This report provides a qualitative characterisation of human resource needs and appraises instruments and programmes in nuclear education and training initiated by various stakeholders in different countries. In this context, it also examines the current and future uses of nuclear research facilities for education and training purposes. Regarding the nuclear training component of workforce competence, it outlines a job taxonomy which could be a basis for addressing the needs of workers across this sector. It presents the taxonomy as a way of enhancing mutual recognition and increasing consistency of education and training for both developed and developing countries.

Nuclear Energy Data 2012/Données sur l'énergie nucléaire 2012
Bilingual, 84 pages, published: 09/24/12
NEA#7058, ISBN: 978-92-64-17785-7

Nuclear Energy Data is the OECD Nuclear Energy Agency’s annual compilation of statistics and country reports documenting the status of nuclear power in the OECD area. Information provided by member country governments includes statistics on installed generating capacity, total electricity produced by all sources and by nuclear power, nuclear energy policies, fuel cycle developments, and projected generating capacity and electricity production to 2035, where available. Following the accident at the Fukushima Daiichi nuclear power plant in March 2011, total nuclear generating capacity and electricity generation declined, principally because of the permanent shutdown of 12 reactors (8 in Germany and 4 in Japan) and the prolonged shutdown of reactors in Japan. The Fukushima Daiichi accident also prompted safety reviews of existing nuclear facilities and led some governments to adopt nuclear phase-out plans. Other governments remained committed to maintaining nuclear power in the energy mix, in some cases pursuing plans to either increase nuclear generating capacity or, as in the cases of Poland and Turkey, to add nuclear generating capacity for the first time. Further details on these and other developments are provided in the publication’s numerous tables, graphs and country reports.
This publication contains “Statlinks”. For each StatLink the reader will find a url which leads to the corresponding spreadsheet. These links work in the same way as an Internet link.

Les Données sur l'énergie nucléaire, la compilation annuelle de statistiques et de rapports nationaux de l’Agence de l’OCDE pour l’énergie nucléaire, présentent des informations communiquées par les gouvernements des pays membres de l'OCDE sur la puissance nucléaire installée, la production d’électricité totale et nucléaire, les politiques nucléaires, les évolutions du cycle du combustible ainsi que, quand elles sont disponibles, des projections jusqu'en 2035 de la puissance nucléaire et de la production d'électricité. Au lendemain de l’accident survenu dans la centrale de Fukushima Daiichi en mars 2011, la puissance installée et la production du parc nucléaire global ont décliné, principalement du fait de la mise hors service de 12 réacteurs (8 en Allemagne et 4 au Japon) et de l’arrêt prolongé d’autres réacteurs au Japon. Cet accident a conduit à réaliser des évaluations de la sûreté des installations et incité certains pays à adopter des plans de sortie du nucléaire. D’autres, en revanche, restent déterminés à conserver le nucléaire dans leur bouquet énergétique, voire à s’équiper de tranches supplémentaires ou, comme la Pologne et la Turquie, de leur premier réacteur de puissance. Le lecteur trouvera de plus amples informations sur ces évolutions et d’autres développements dans les nombreux tableaux, graphiques et rapports nationaux que contient cet ouvrage.

Meeting the growing demand for energy, and electricity in particular, while addressing the need to curb greenhouse gas emissions and to ensure security of energy supply, is one of the most difficult challenges facing the world’s economies. No single technology can respond to this challenge, and the solution which policy-makers are seeking lies in the diversification of energy sources.

Although nuclear energy currently provides over 20% of electricity in the OECD area and does not emit any carbon dioxide during production, it continues to be seen by many as a controversial technology. Public concern remains over its safety and the management of radioactive waste, and financing such a capital-intensive technology is a complex issue. The role that nuclear power will play in the future depends on the answers to these questions, several of which are provided in this up-to-date review of the status of nuclear energy, as well as on the outcome of research and development on the nuclear fuel cycle and reactor technologies.

Nuclear Energy and Renewables
System Effects in Low-carbon Electricity Systems
English, 252 pages, published: 11/09/12
NEA#7056, ISBN: 978-92-64-18851-8
Available online at: http://www.oecd-nea.org/ndd/pubs/2012/7056-system-effects.pdf
This report addresses the increasingly important interactions of variable renewables and dispatchable energy technologies, such as nuclear power, in terms of their effects on electricity systems. These effects add costs to the production of electricity, which are not usually transparent. The report recommends that decision-makers should take into account such system costs and internalise them according to a “generator pays” principle, which is currently not the case. Analysing data from six OECD/NEA countries, the study finds that including the system costs of variable renewables at the level of the electricity grid increases the total costs of electricity supply by up to one-third, depending on technology, country and penetration levels. In addition, it concludes that, unless the current market subsidies for renewables are altered, dispatchable technologies will increasingly not be replaced as they reach their end of life and consequently security of supply will suffer. This implies that significant changes in management and cost allocation will be needed to generate the flexibility required for an economically viable coexistence of nuclear energy and renewables in increasingly decarbonised electricity systems.

Nuclear Fuel Safety Criteria Technical Review
Second Edition
English, 80 pages, published: 09/14/12
NEA#7072, ISBN: 978-92-64-99178-1
Available online at: http://www.oecd-nea.org/nsd/reports/2012/nea7072-fuel-safety-criteria.pdf
Most of the current nuclear fuel safety criteria were established during the 1960s and early 1970s. Although these criteria were validated against experiments with fuel designs available at that time, a number of tests were based on unirradiated fuels. Additional verification was performed as these designs evolved, but mostly with the aim of showing that the new designs adequately complied with existing criteria, and not to establish new limits.

In 1996, the OECD Nuclear Energy Agency (NEA) reviewed existing fuel safety criteria, focusing on new fuel and core designs, new cladding materials and industry manufacturing processes. The results were published in the Nuclear Fuel Safety Criteria Technical Review of 2001. The NEA has since re-examined the criteria. A brief description of each criterion and its rationale are presented in this second edition, which will be of interest to both regulators and industry (fuel vendors, utilities).

The application of lessons learnt from the International Reporting System for Operating Experience (IRS) is an essential element for enhancing the safe operation of nuclear power plants (NPPs) throughout the world. The IRS provides a mechanism for the exchange of information related to the incident, actions taken, root cause analysis and lessons learnt. This feedback on how to adequately remedy, or avoid, possible challenges and precursors is of paramount importance to operational safety. The IRS improves international awareness of potential challenges, actual incidents and “precursors” in NPP operations. The heightened awareness generated by feedback from operating experience has resulted in numerous improvements to equipment, procedures and training in many NPPs. The application of operational feedback also benefits the design of the next generation of NPPs. Operating experience has demonstrated that design modification issues documented in IRS reports can have a significant impact on safety. The IRS is jointly operated and managed by the OECD Nuclear Energy Agency (OECD/NEA) and the International Atomic Energy Agency (IAEA).

Reversibility and Retrievability in Planning for Geological Disposal of Radioactive Waste
Proceedings of the "R&R" International Conference and Dialogue, 14-17 December 2010, Reims, France
English, 236 pages, published: 12/31/12
NEA#6993, ISBN: 978-92-64-99185-9

Deep geological repositories of radioactive waste are designed and licensed based on a model of long-term safety which does not require the active presence of man. During the period of stepwise development of such repositories, reversibility of decisions and retrievability of the waste are widely thought to be beneficial. Reversibility and retrievability are not requirements for long-term safety. They are instead about implementing a process that responds to ethical and precautionary obligations without compromising safety. How are the concepts of reversibility and retrievability understood in the various nuclear countries? How do they appear in national waste management legislation, regulation and operational programmes, and how can they be implemented?
The “R&R” project of the OECD Nuclear Energy Agency (NEA) culminated in an International Conference and Dialogue on Reversibility and Retrievability in December 2010. This open meeting brought together regulators, policy makers, elected officials, experts in social sciences, and representatives of civil society and stakeholder groups in addition to waste management professionals. These proceedings include the texts of 50 presentations and the “International Retrievability Scale” – a tool to support dialogue with stakeholders and to help establish a common international framework.

The most widely adopted solution for the definitive management of high-level radioactive waste involves its emplacement in deep geological repositories whose safety should not depend on the active presence of man. In this context, national programmes are considering whether and how to incorporate the concepts of reversibility of decisions and retrievability of waste, including to what extent retrieval can or should be facilitated at the design stage of a repository, and if so over what timescales.
This brochure delivers the key findings and observations of the OECD Nuclear Energy Agency (NEA) project on reversibility and retrievability conducted from 2007 to 2011 with the participation of 15 countries and 2 international organisations. It outlines the activities undertaken and points to further resources. While focused on deep geological disposal, the pragmatic and precise information provided may also be pertinent to sub-surface disposal and to decision-making processes more generally. This brochure, and related project documents, will be of interest to technical and policy professionals and civil society stakeholders concerned with radioactive waste disposal.

The Economics of Long-term Operation of Nuclear Power Plants
English, 114 pages, published: 12/19/12
NEA#7054, ISBN: 978-92-64-99205-4
Available online at: http://www.oecd-nea.org/ndd/reports/2012/7054-long-term-operation-npps.pdf
Refurbishment and long-term operation (LTO) of existing nuclear power plants (NPPs) today are crucial to the competitiveness of the nuclear industry in OECD countries as existing nuclear power plants produce baseload power at a reliable cost. A number of nuclear power plants, most notably 73 units in the United States (up to 2012), have been granted lifetime extensions of up to 60 years, a development that is being keenly watched in other OECD countries. In many of these (e.g. France, Switzerland), there is no legal end to the operating licence, but continued operation is based on the outcomes of periodic safety reviews.
This study analyses technical and economic data on the upgrade and lifetime extension experience in OECD countries. A multi-criteria assessment methodology is used considering various factors and parameters reflecting current and future financial conditions of operation, political and regulatory risks, the state of the plants’ equipment and the general role of nuclear power in the country’s energy policy.
The report shows that long-term operation of nuclear power plants has significant economic advantages for most utilities envisaging LTO programmes. In most cases, the continued operation of NPPs for at least ten more years is profitable even taking into account the additional costs of post-Fukushima modifications, and remains cost-effective compared to alternative replacement sources.

- Français: Image et rôle de l'autorité de sûreté nucléaire dans la gestion des déchets radioactifs 
In the area of radioactive waste management, the regulator or safety authority has emerged in recent years as a principal actor in the eyes of civil society. This study shows how regulators are increasing their interaction with society while still retaining – or ­reinforcing – their independence and how they play their role within the stepwise ­licensing and decision-making processes now adopted in most countries. Safety is ensured by a “regulatory system”, in which a host of players, including local ­stakeholders, have a vital role to play. The technical regulator has come to be considered as the “people’s expert”, concentrating knowledge useful to local communities as they deliberate the hosting of a waste storage or disposal facility.
This report provides a useful update on the changing role of the regulator as well as insights that will be helpful to the many countries that are considering, or are preparing for, storage or disposal of radioactive waste either in near-surface facilities or deeper underground. While it focuses on the developments in waste management and disposal, the trends it describes are probably relevant throughout the nuclear field.

Sweden is at the forefront among countries developing plans for a deep geological repository of highly radioactive waste. There is no such repository in operation yet worldwide, but Sweden, Finland and France are approaching the licensing stage. At the request of the Swedish government, the NEA organised an international peer review of the post-closure radiological safety case produced by the Swedish Nuclear Fuel and Waste Management Company (SKB) in support of the application for a general licence to construct and operate a spent nuclear fuel geological repository in the municipality of Östhammar. The purpose of the review was to help the Swedish government, the public and relevant organisations by providing an international reference regarding the maturity of SKB’s spent fuel disposal programme vis-à-vis best practices in long-term disposal safety and radiological protection. The International Review Team (IRT) consisted of ten international specialists, who were free of conflict of interest with the SKB and brought complementary expertise to the review. This report provides the background and findings of the international peer review. The review’s findings are presented at several levels of detail in order to be accessible to both specialist and non-specialist readers.

The Role of Nuclear Energy in a Low-carbon Energy Future
English, 92 pages, published: 06/18/12

Available online at: http://www.oecd-nea.org/nsd/reports/2012/nea6887-role-nuclear-low-carbon.pdf
This report assesses the role that nuclear energy can play in supporting the transition to a low-carbon energy system. It begins by considering the greenhouse gas emissions from the full nuclear fuel cycle, reviewing recent studies on indirect emissions and assessing the impact that nuclear power could make in reducing greenhouse gas emissions.
The report provides estimates of the construction rates that would be needed to meet the projected expansion of nuclear power foreseen by many energy scenarios published by international organisations. It then assesses the economic, technical, societal and institutional challenges represented by such an expansion to identify the most significant barriers. The capacity of nuclear power plants to operate in an electricity system with a large share of renewables, and the impact of smart grid technologies are also examined. Finally, long-term prospects for nuclear energy are discussed in terms of development of new reactor and fuel cycle technologies, non-electric applications and new operational and regulatory constraints that could arise as a consequence of climate change.

The reliable supply of molybdenum-99 (99Mo) and its decay product, technetium-99m (99mTc), is a vital component of modern medical diagnostic practices. At present, most of the global production of 99Mo is from highly enriched uranium (HEU) targets. However, all major 99Mo-producing countries have recently agreed to convert to using low-enriched uranium (LEU) targets to advance important non-proliferation goals, a decision that will have implications for the global supply chain of 99Mo/99mTc and the long-term supply reliability of these medical isotopes.
This study provides the findings and analysis from an extensive examination of the 99Mo/99mTc supply chain by the OECD/NEA High-level Group on the Security of Supply of Medical Radioisotopes (HLG-MR). It presents a comprehensive evaluation of the potential impacts of converting to the use of LEU targets for 99Mo production on the global 99Mo/99mTc market in terms of costs and available production capacity, and the corresponding implications for long-term supply reliability. In this context, the study also briefly discusses the need for policy action by governments in their efforts to ensure a stable and secure long-term supply of 99Mo/99mTc.

Thermodynamic Sorption Modelling in Support of Radioactive Waste Disposal Safety Cases
NEA Sorption Project Phase III
English, 152 pages, published: 05/04/12
NEA#6914, ISBN: 978-92-64-17781-9
Available online at: http://www.oecd-nea.org/rwm/docs/2013/6914-sorption-III.pdf
A central safety function of radioactive waste disposal repositories is the prevention or sufficient retardation of radionuclide migration to the biosphere. Performance assessment exercises in various countries, and for a range of disposal scenarios, have demonstrated that one of the most important processes providing this safety function is the sorption of radionuclides along potential migration paths beyond the engineered barriers. Thermodynamic sorption models (TSMs) are key for improving confidence in assumptions made about such radionuclide sorption when preparing a repository's safety case. This report presents guidelines for TSM development as well as their application in repository performance assessments. They will be of particular interest to the sorption modelling community and radionuclide migration modellers in developing safety cases for radioactive waste disposal.

Trends towards Sustainability in the Nuclear Fuel Cycle: Executive Summary
English, 12 pages, published: 01/16/12
NEA#7069
Available online at: http://www.oecd-nea.org/ndd/reports/2011/trends-nuclear-fuel-cycle-ex.pdf
Interest in expanding nuclear power to cope with rising demand for energy and potential climate change places increased attention on the nuclear fuel cycle and whether significant moves are being taken towards ensuring sustainability over the long term. Future nuclear power programme decisions will be increasingly based on strategic considerations involving the complete nuclear fuel cycle, as illustrated by the international joint projects for Generation IV reactors. Currently, 90% of installed reactors worldwide operate on a once-through nuclear fuel cycle using uranium-oxide fuel. While closing the fuel cycle has been a general aim for several decades, progress towards that goal has been slow. This report reviews developments in the fuel cycle over the past ten years, potential developments over the next decade and the outlook for the longer term. It analyses technological developments and government actions (both nationally and internationally) related to the fuel cycle, and examines these within a set of sustainability parameters in order to identify trends and to make recommendations for further actions.

Acceptance criteria for emergency core cooling systems (ECCS) define the maximum temperature and degree of oxidation in order to avoid excessive embrittlement and hence failure of the fuel cladding, which would affect core cooling in the case of a loss-of-coolant accident (LOCA). The criteria are mainly based on experimental data obtained in the 1970s-80s. Several types of tests have been performed to evaluate structural integrity and embrittlement of the cladding under LOCA conditions, and consequently different test methodologies have been used for determining the cladding embrittlement criteria. The current trend towards high burn-up and the use of new cladding alloys has increased the need for international discussions on these test methodologies and acceptance criteria. In response, the NEA Committee on the Safety of Nuclear Installations (CSNI) and its Working Group on Fuel Safety produced this technical opinion paper, which should be of particular interest to nuclear safety regulators, nuclear power plant operators and fuel researchers.

Carbon Pricing, Power Markets and the Competitiveness of Nuclear Power
English, 108 pages, published: 07/12/11
NEA#6982, ISBN: 978-92-64-11887-4
Available online at: http://www.oecd-nea.org/ndd/pubs/2011/6982-carbon-pricing.pdf
This study assesses the competitiveness of nuclear power against coal- and gas-fired power generation in liberalised electricity markets with either CO2 trading or carbon taxes. It uses daily price data for electricity, gas, coal and carbon from 2005 to 2010, which encompasses the first years of the European Emissions Trading System (EU ETS), the world’s foremost carbon trading framework. The study shows that even with modest carbon pricing, competition for new investment in electricity markets will take place between nuclear energy and gas-fired power generation, with coal-fired power struggling to be profitable. The outcome of the competition between nuclear and gas-fired generation hinges, in addition to carbon pricing, on the capital costs for new nuclear power plant construction, gas prices and the profit margins applied. Strong competition in electricity markets reinforces the attractiveness of nuclear energy, as does carbon pricing, in particular when the latter ranges between USD 40 and USD 70 per tonne of CO2. The data and analyses contained in this study provide a robust framework for assessing cost and investment issues in liberalised electricity markets with carbon pricing.

Evolution of ICRP Recommendations – 1977, 1990 and 2007
Changes in Underlying Science and Protection Policy and Case Study of their Impact on European and UK Domestic Regulation
English, 112 pages, published: 02/28/11
NEA#6920, ISBN: 978-92-64-99153-8
Volume of the series: Radiation Protection
Available online at: http://www.oecd-nea.org/rp/reports/2011/nea6920-ICRP-recommendations.pdf
Radiological protection philosophy, regulation and application have evolved significantly over the last 30 years, adapting to the ever-changing landscapes of scientific understanding and societal values. This report provides a methodical assessment of these changes. Starting with radiological protection in the 1970s, it describes the philosophical differences between International Commission on Radiological Protection (ICRP) Publication 26, issued in 1977, and ICRP Publication 60, issued in 1990, as well as the regulatory evolution that was necessary to effectively implement the changes. It then examines the philosophical and regulatory changes between ICRP Publication 60 and ICRP Publication 103 of 2007. Although the regulatory changes needed to implement Publication 103 are, in practice, yet to come, the report provides a seasoned view of what these changes will most likely be, and what efforts will be necessary to successfully implement them.

Improving Nuclear Regulation
NEA Regulatory Guidance Booklets, Volumes 1-14
English, 270 pages, published: 05/30/11

Available online at: http://www.oecd-nea.org/nsd/docs/2011/cnra-r2011-10.pdf
A common theme throughout the series of NEA regulatory guidance reports, or “green booklets”, is the premise that the fundamental objective of all nuclear safety regulatory bodies is to ensure that nuclear facilities are continuously maintained and operated in an acceptably safe manner. In meeting this objective the regulator must bear in mind that it is the operator that has responsibility for safely operating the nuclear facility; the role of the regulator is to assess and to provide assurance regarding the operator’s activities in terms of assuming that responsibility.
The full series of these reports was brought together in one edition for the first time in 2009 and was widely found to be a useful resource. This second edition comprises 14 volumes, including the latest on The Nuclear Regulator's Role in Assessing Licensee Oversight of Vendor and Other Contracted Services. The reports address various challenges that could apply throughout the lifetime of a nuclear facility, including design, siting, manufacturing, construction, commissioning, operation, maintenance and decommissioning. The compilation is intended to serve as a knowledge management tool both for current regulators and the new nuclear professionals and organisations entering the regulatory field.

Potential Benefits and Impacts of Advanced Nuclear Fuel Cycles with Actinide Partitioning and Transmutation
English, 74 pages, published: 09/29/11
NEA#6894, ISBN: 978-92-64-99165-1
Available online at: http://www.oecd-nea.org/science/reports/2011/6894-benefits-impacts-advanced-fuel.pdf
This report provides a comparative analysis of different studies performed to assess the potential impact of partitioning and transmutation (P&T) on different types of geological repositories for radioactive waste in various licensing and regulatory environments. Criteria, metrics and impact measures have been analysed and compared with the goal of providing an objective comparison of the state of the art to help shape decisions on options for future advanced fuel cycles.
P&T allows a reduction of the inventory of the emplaced materials which can have a significant impact on the repository. Such a reduction can also make the uncertainty about repository performance less important both during normal evolution and in the case of disruptive scenarios. While P&T will never replace the need for waste repositories, it has the potential to significantly improve public perception regarding the ability to effectively manage radioactive waste by largely reducing the transuranic (TRU) waste masses to be stored and, consequently, to improve public acceptance of the geological repositories. Both issues are important for the future sustainability of nuclear power.

Decisions regarding radiological protection are informed by science, including its uncertainties, influenced by stakeholder concerns, driven by prevailing circumstances, and broadly based on values and judgments. However, the processes by which protection decisions are taken do not always sufficiently articulate the scientific and value-judgment elements on which decisions are based. To assist decision makers at all levels to further clarify the various aspects of their decisions, and to assist scientists and regulators in better understanding each other’s contributions to radiological protection decisions, the NEA Committee on Radiation Protection and Public Health (CRPPH) has held two workshops addressing science and values in radiological protection. This report summarises the discussions and conclusions of the first two workshops in this innovative series, and suggests the way forward in preparing the discussions at the third science and values workshop.

Contracted services are an integral part of the design, construction and operation of a nuclear facility. Changes in the nuclear industry sector, including varied availability of nuclear expertise, the expansion of the international supply market and the introduction of new technologies, have tended to increase licensees’ use of contracted services. These changes have created challenges for licensees and regulators related to the retention of nuclear expertise, the effective management of the interfaces between the licensees and contractors, and the oversight of contractor manufacturing quality in the context of greater multinational diversity. The regulatory body must address these challenges to provide assurance that the licensees maintain their responsibility for the safety of the facilities, regardless of who provides goods and services or where the activities involved in the supply chain take place. This report is intended to assist regulatory bodies in assessing their current practices for the regulatory oversight of licensees’ use of contractors, and adapting them where necessary to meet the evolving situation.

The reliable supply of molybdenum-99 (99Mo) and its decay product, technetium-99m (99mTc), is a vital component of modern medical diagnostic practices. Disruptions in the supply chain of these radioisotopes can delay or prevent important medical testing services. Unfortunately, supply reliability has declined over the past decade, due to unexpected or extended shutdowns at the few ageing, 99Mo-producing, research reactors and processing facilities. These shutdowns have recently created global supply shortages.

This report provides the findings and analysis of two years of extensive examination of the 99Mo/99mTc supply chain by the OECD/NEA High-level Group on the Security of Supply of Medical Radioisotopes (HLG-MR). It puts forth a comprehensive policy approach that would help ensure long-term supply security of 99Mo/99mTc, detailing the essential steps to be taken by governments, industry and the health community to address the vulnerabilities of the supply chain, including its economic structure.

Other language(s):
- Français: Intégration du retour d'expérience du démantèlement à la conception et l'exploitation des futures centrales nucléaires 
Experience from decommissioning projects suggests that the decommissioning of nuclear power plants could be made easier if it received greater consideration at the design stage and during the operation of the plants. Better forward planning for decommissioning results in lower worker doses and reduced costs. When appropriate design measures are not taken at an early stage, their introduction later in the project becomes increasingly difficult. Hence, their early consideration may lead to smoother and more effective decommissioning.

It is now common practice to provide a preliminary decommissioning plan as part of the application for a licence to operate a nuclear facility. This means, in turn, that decommissioning issues are being considered during the design process. Although many design provisions aiming at improved operation and maintenance will be beneficial for decommissioning as well, designers also need to consider issues that are specific to decommissioning, such as developing sequential dismantling sequences and providing adequate egress routes. These issues and more are discussed in this report.

Boiling Water Reactor Turbine Trip (TT) Benchmark - Vol. IV
Volume IV: Summary Results of Exercise 3
English, 276 pages, published: 10/08/10
NEA#6050, ISBN: 978-92-64-99137-8
Available online at: http://www.oecd-nea.org/science/reports/2010/nea6050-tt-benchmark-vol4.pdf
In the field of coupled neutronics/thermal-hydraulics computation there is a need to enhance scientific knowledge in order to develop advanced modelling techniques for new nuclear technologies and concepts, as well as for current applications.

Recently developed “best-estimate” computer code systems for modelling 3-D coupled neutronics/thermal-hydraulics transients in nuclear cores and for coupling of the core phenomena and system dynamics (PWR, BWR, VVER) need to be compared against each other and validated against results from experiments. International benchmark studies have been set up for that purpose.

The present volume is the last in a series of four and summarises the results of the third benchmark exercise, which analyses a turbine trip (TT) in a BWR in its entirety, involving pressurisation events in which the coupling between core phenomena and system dynamics plays an important role. Exercise 3 also analyses four extreme scenarios which allowed participants to test the capabilities of their code(s) in terms of coupling and feedback modelling. The data made available from experiments carried out at the plant make the present benchmark particularly valuable. The data used are from events at the Peach Bottom 2 reactor (a GE-designed BWR/4).

- Français: Evaluation de risques d'accidents nucléaires comparés à ceux d'autres filières énergétiques 
Nuclear accident risks are raised frequently in discussions of the acceptability of nuclear power generation, often framed in the context of the Three Mile Island and Chernobyl accidents. In reality, the safety record of nuclear power plants, by comparison with other electricity generation sources, is very good. This report describes how safety has been enhanced in nuclear power plants over the years, as the designs have progressed from Generation I to Generation III, and why it is important that safety remain the highest priority. This is illustrated by considering core damage frequencies and large radioactive release frequencies for each generation of nuclear power plants. It also compares severe accident data (those resulting in five or more fatalities) between different energy sources, both for immediate fatalities and for delayed (latent) fatalities, recognising that the latter data are often more difficult to estimate. Finally, it uses results of opinion surveys to analyse public confidence in nuclear operations and how this is correlated with trust in legislation and regulatory systems. It has been written for a general audience.

Cost Estimation for Decommissioning
An International Overview of Cost Elements, Estimation Practices and Reporting Requirements
English, 80 pages, published: 05/17/10
NEA#6831, ISBN: 978-92-64-99133-0
Available online at: http://www.oecd-nea.org/rwm/reports/2010/nea6831-cost-estimation-decommissioning.pdf
This report is based on a study carried out by the NEA Decommissioning Cost Estimation Group (DCEG) on decommissioning cost elements, estimation practices and reporting requirements. Its findings indicate that cost methodologies need to be updated continuously using cost data from actual decommissioning projects and hence, systematic approaches need to be implemented to collect these data. The study also concludes that changes in project scope may have the greatest impact on project costs. Such changes must therefore be identified immediately and incorporated into the estimate. Finally, the report notes that more needs to be done to facilitate the comparison of estimates, for example by providing a reporting template for national estimates.

Decommissioning Considerations for New Nuclear Power Plants
English, 16 pages, published: 06/07/10
NEA#6833, ISBN: 978-92-64-99132-3
Available online at: http://www.oecd-nea.org/rwm/reports/2010/nea6833-decommissioning-considerations.pdf
Experience from decommissioning projects suggests that the decommissioning of nuclear power plants could be made easier if this aspect received greater consideration at the design stage and during operation of the plants. Better forward planning for decommissioning results in lower worker doses and reduced costs. When appropriate design measures are not taken at an early stage, their introduction later in the project becomes increasingly difficult. Hence, their early consideration may lead to smoother and more effective decommissioning operations. This report provides an overview of key decommissioning issues which are useful to consider when designing new nuclear power plants.

Radioactive waste is associated with all phases of the nuclear fuel cycle as well as the use of radioactive materials in medicine, research and industry. For the most hazardous and long-lived waste, the solution being investigated worldwide is disposal in engineered repositories deep underground. The importance of geoscientific information in selecting a site for geological disposal has long been recognised, but there has been growing acknowledgement of the broader role of this information in assessing and documenting the safety of disposal. The OECD/NEA Approaches and Methods for Integrating Geological Information in the Safety Case (AMIGO) project has demonstrated that geological data and understanding serve numerous roles in safety cases. The project, which ran from 2002 to 2008, underscored the importance of integrating geoscientific information in the development of a disposal safety case and increasingly in the overall process of repository development, including, for example, siting decisions and ensuring the practical feasibility of repository layout and engineering.

Other language(s):
- Français: Au-delà des seules réalités concrètes : la dimension symbolique de la gestion des déchets radioactifs 
Key concepts of radioactive waste management, such as safety, risk, reversibility and retrievability, carry different meanings for the technical community and for non-technical stakeholders. Similarly, socio-economic concepts, including community, landscape and benefit packages, are interpreted differently by diverse societal groups. Opinions and attitudes are not simply a faithful reflection of decision making, actual events and communicated messages; perceptions and interpretations of events and objects also play a role. This report presents key issues and examples in order to build awareness of the importance of symbols and symbolism in communicating about perceptions and interpretations. It adds to the recognition that dialogue amongst stakeholders is shaped by dimensions of meaning that reach beyond dictionary definitions and are grounded in tradition and social conventions. A better understanding of these less obvious or conspicuous realities should help find additional ways of creating constructive relationships amongst stakeholders.

NUPEC BWR Full-size Fine-mesh Bundle Test (BFBT) Benchmark (Vol. II)
Volume II: Uncertainty and Sensitivity Analyses of Void Distribution and Critical Power - Specification
English, 44 pages, published: 07/30/10
NEA#6343, ISBN: 978-92-64-99124-8
Available online at: http://www.oecd-nea.org/science/docs/2010/NUPEC-BWR-VOL2.pdf
The government of Japan and the Japanese Nuclear Power Engineering Corporation (NUPEC) have released high-quality data, based on a series of void measurements using full-size mock-up tests for boiling water reactors (BWRs), with the aim of assisting the scientific community to advance its understanding of the two-phase flow (a system containing both gas and liquid) in BWR fuel bundles.

An international benchmark, based on the NUPEC data, has been defined to encourage advancement in the development of two-phase flow theory, which is of importance, for example, for the evaluation of the safety margins in a reactor. The benchmark specifications are being designed so that it systematically assesses and compares the capability of the numerical models to predict detailed void distributions and critical powers.

This report is the second in a series and describes the specification of the sensitivity and uncertainty analysis exercises undertaken to assess the accuracy of the results obtained when modelling basic thermal-hydraulics in a single channel relative to void fraction and critical power. Further volumes will be published, with a synthesis showing to what extent the most recent models are capable of predicting two-phase flow in BWR fuel bundles.

Nuclear Fuel Behaviour under Reactivity-initiated Accident (RIA) Conditions
State-of-the-art Report
English, 208 pages, published: 03/24/10
NEA#6847, ISBN: 978-92-64-99113-2
Available online at: http://www.oecd-nea.org/nsd/reports/2010/nea6847-behaviour-RIA.pdf
Considerable experimental and analytical work has been performed in recent years which has led to a broader and deeper understanding of phenomena related to reactivity-initiated accidents (RIAs). Further, newly designed fuels – such as mixed-oxide (MOX) fuel and rods with new cladding – have been introduced which might behave differently than those used previously, both under normal operating conditions and during transients. Compared with 20 years ago, fuel burn-up has been significantly increased. These and other factors have led the NEA Committee on the Safety of Nuclear Installations (CSNI) and its Working Group on Fuel Safety to produce this state-of-the-art report. The report should be of particular interest to nuclear safety regulators, nuclear plant operators and fuel researchers.

The Information System on Occupational Exposure (ISOE) was created by the OECD Nuclear Energy Agency in 1992 to promote and co-ordinate international co-operative undertakings in the area of occupational radiological protection at nuclear power plants. ISOE provides experts in occupational radiological protection with a forum for communication and exchange of experience.

At the end of 2008, the ISOE programme included 59 participating utilities in 26 countries (278 operating units and 32 shutdown units), as well as the regulatory authorities of 22 countries. The ISOE database, publications, annual symposia and ISOE Network website facilitate the exchange amongst participants of operational experience and lessons learnt in the optimisation of occupational radiological protection.

The Eighteenth Annual Report of the ISOE Programme summarises occupational exposure data trends and ISOE achievements made during 2008. Principal developments in ISOE participating countries are also described.

ISOE is jointly sponsored by the OECD Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA).

Other language(s):
- English: Occupational Radiological Protection Principles and Criteria for Designing New Nuclear Power Plants 
Global demand for electricity continues to grow and numerous new nuclear power plants (NPPs) are being planned or constructed in NEA member countries. Most of these new NPPs will be of the third generation, and will be designed for as long as 80 years of operation. The successful design, construction and operation of these plants will depend broadly on appropriately implementing the lessons from experience accumulated to date.

This case study introduces a policy and technical framework that may be used when formulating technical assistance and guidance for senior managers of NPPs, designers, manufacturers, contractors and authorities responsible for regulating occupational radiation exposure. It is aimed in particular at assisting design and license assessments of new NPPs. Although not targeting the needs of countries introducing nuclear power for the first time, this case study can also provide valuable input on occupational radiological protection issues for the implementation of new nuclear energy programmes.

This report summarises and reviews the concepts relevant to the “optimisation” of geological disposal systems as they are outlined in national and international guidance. It also presents a set of observations and key questions. Overall, the report shows that, when addressing “optimisation”, there is ample scope for clarifying concepts, facts and possibilities and for ensuring that regulatory guidance is sufficiently precise and implementable. The intention is that this report should serve as a basis for discussion within and beyond NEA committees and expert groups.

Partnership approaches are effective in achieving a balance between the requirements of fair representation and competent participation. With host community support, they also help ensure the desirable combination of a licensable site and management concept as well as a balance between compensation, local control and development opportunities. This report provides up-to-date information on experience with local partnership arrangements in 13 countries. The characteristics, advantages and aims of community partnerships are also described in addition to the concept's evolution over the past decade.

This joint report by the International Energy Agency (IEA) and the OECD Nuclear Energy Agency (NEA) is the seventh in a series of studies on electricity generating costs. It presents the latest data available for a wide variety of fuels and technologies, including coal and gas (with and without carbon capture), nuclear, hydro, onshore and offshore wind, biomass, solar, wave and tidal as well as combined heat and power (CHP). It provides levelised costs of electricity (LCOE) per MWh for almost 200 plants, based on data covering 21 countries (including four major non-OECD countries), and several industrial companies and organisations. For the first time, the report contains an extensive sensitivity analysis of the impact of variations in key parameters such as discount rates, fuel prices and carbon costs on LCOE. Additional issues affecting power generation choices are also examined.

The study shows that the cost competitiveness of electricity generating technologies depends on a number of factors which may vary nationally and regionally. Readers will find full details and analyses, supported by over 130 figures and tables, in this report which is expected to constitute a valuable tool for decision makers and researchers concerned with energy policies and climate change.

Other language(s):
- Français: L'opinion publique et l'énergie nucléaire 
Public attitudes to nuclear power are critical in shaping nuclear policies in OECD/NEA countries and the latter will only be able to make use of this energy source if a well-informed public considers that its benefits outweigh its risks. This report provides a number of insights into public attitudes towards nuclear power. Support for nuclear energy is generally correlated with the level of experience of and knowledge about nuclear power. Interestingly, while the public is generally aware of the contribution of nuclear power to ensuring security of energy supply, its potential contribution to combating climate change is less well recognised. Solving the waste disposal issue would also significantly increase the level of public support. Furthermore, OECD/NEA governments may wish to reflect carefully on how to react to these results as, according to the surveys, they are the least trusted source on energy issues, far behind regulators, non-governmental organisations and scientists.

Large volumes of hazardous wastes are produced each year, however only a small proportion of them are radioactive. While disposal options for hazardous wastes are generally well established, some types of hazardous waste face issues similar to those for radioactive waste and also require long-term disposal arrangements. The objective of this NEA study is to put the management of radioactive waste into perspective, firstly by contrasting features of radioactive and hazardous wastes, together with their management policies and strategies, and secondly by examining the specific case of the wastes resulting from carbon capture and storage of fossil fuels. The study seeks to give policy makers and interested stakeholders a broad overview of the similarities and differences between radioactive and hazardous wastes and their management strategies.

Self-sealing of Fractures in Argillaceous Formations in the Context of Geological Disposal of Radioactive Waste
Review and Synthesis
English, 312 pages, published: 06/01/10
NEA#6184, ISBN: 978-92-64-99095-1
Available online at: http://www.oecd-nea.org/rwm/reports/2010/nea6184-self-sealing.pdf
Disposal of high-level radioactive waste and spent nuclear fuel in engineered facilities, or repositories, located deep underground in suitable geological formations is being developed worldwide as the reference solution to protect humans and the environment both now and in the future. Assessing the long-term safety of geological disposal requires developing a comprehensive understanding of the geological environment. The transport pathways are key to this understanding. Of particular interest are fractures in the host rock, which may be either naturally occurring or induced, for example, during the construction of engineered portions of a repository. Such fractures could provide pathways for migration of contaminants.

In argillaceous (clay) formations, there is evidence that, over time, fractures can become less conductive and eventually hydraulically insignificant. This process is commonly termed “self-sealing”. The capacity for self-sealing relates directly to the function of clay host rocks as migration barriers and, consequently, to the safety of deep repositories in those geological settings.

This report – conducted under the auspices of the NEA Clay Club – reviews the evidence and mechanisms for self-sealing properties of clays and evaluates their relevance to geological disposal. Results from laboratory tests, field investigations and geological analogues are considered. The evidence shows that, for many types of argillaceous formations, the understanding of self-sealing has progressed to a level that could justify its inclusion in performance assessments for geological repositories.

Particle accelerators have evolved over the last decades from simple devices to powerful machines, and are having an increasingly important impact on research, technology and daily life. Today they cover a wide range of applications including material science and medical applications. In recent years, requirements from new technological and research applications have emerged while the number of accelerator facilities in operation, being commissioned, designed or planned has significantly grown. Their parameters (such as the beam energy, beam currents and intensities, and target composition) vary widely, giving rise to new radiation shielding aspects and problems.

Particle accelerators must be operated in safe ways to protect operators, the public and the environment. As the design and use of these facilities evolve, so must the analytical methods used in the safety analyses. These workshop proceedings review the state of the art in radiation shielding of accelerator facilities and irradiation targets. They also evaluate progress on the development of modelling methods used to assess the effectiveness of such shielding as part of safety analyses.

Strategic Aspects of Nuclear and Radiological Emergency Management
Planning for Effective Decision Making; Consequence Management and Transition to Recovery
English, 72 pages, published: 10/05/10
NEA#6387, ISBN: 978-92-64-99146-0
Available online at: http://www.oecd-nea.org/rp/reports/2010/nea6387-strategic-aspects-of-nuclear.pdf
The collective experience of the NEA Working Party on Nuclear Emergency Matters (WPNEM), and in particular, the experience from the International Nuclear Emergency Exercise (INEX) series, has shown that it is important to plan and to implement emergency response actions based on a guiding strategic vision. Within this context, Strategic Aspects of Nuclear and Radiological Emergency Management presents a framework of strategic planning elements to be considered by national emergency management authorities when establishing or enhancing processes for decision making, and when developing or implementing protection strategies. The focus is on nuclear or radiological emergency situations leading to complex preparedness and response conditions, involving multiple jurisdictions and significant international interfaces.

The report is aimed at national emergency management authorities, international organisations and those who are seeking to improve the effectiveness of emergency management. Its goal is to provide insights into decision-making processes within existing emergency planning arrangements. It also highlights common areas of good practice in decision making. Specific areas for improvement, identified during the INEX-3 consequence management exercise, are included, particularly in support of decision making for countermeasures for consequence management and the transition to recovery.

What contribution can nuclear energy make to improve the security of energy supply? This study, which examines a selection of OECD member countries, qualitatively and quantitatively validates the often intuitive assumption that, as a largely domestic source of electricity with stable costs and no greenhouse gas emissions during production, nuclear energy can make a positive contribution. Following an analysis of the meaning and context of security of supply, the study uses transparent and policy-relevant indicators to show that, together with improvements in energy efficiency, nuclear energy has indeed contributed significantly to enhanced energy supply security in OECD countries over the past 40 years.

The Supply of Medical Radioisotopes
An Economic Study of the Molybdenum-99 Supply Chain
English, 128 pages, published: 09/16/10
NEA#6967, ISBN: 978-92-64-99149-1

The reliable supply of molybdenum-99 (Mo-99) and its decay product, technetium-99m (Tc-99m), is a vital component of modern medical diagnostic practices. Disruptions in the supply chain of these radioisotopes – which cannot be effectively stored – can suspend important medical testing services. Unfortunately, supply reliability has declined over the past decade, due to unexpected or extended shutdowns at the few ageing, Mo-99 producing, research reactors and processing facilities. These shutdowns have created global supply shortages.

This study offers a unique analysis of the economic structure and present state of the Mo-99/Tc-99m supply chain. It finds that the shortages are a symptom of a longer-term problem linked to insufficient capital investment, which has been brought about by an economic structure that does not provide sufficient remuneration for producing Mo-99 or support for developing additional production and processing infrastructure. To assist governments and other decision makers in their efforts to ensure long-term, reliable supply of these important medical isotopes, the study presents options for creating a sustainable economic structure. The study will also enhance understanding amongst stakeholders of the costs of supplying Mo-99 and ultimately contribute to a better functioning market.

Towards Greater Harmonisation of Decommissioning Cost Estimates
English, 16 pages, published: 03/22/10
NEA#6867, ISBN: 978-92-64-99093-7
Volume of the series: Radioactive Waste Management

Other language(s):
- Français: Vers une harmonisation des estimations des coûts du déclassement 
Currently, the format, content and practice of cost estimation vary considerably both within and between countries, which makes it very difficult to compare estimates, even for similar types of facilities. The reasons are largely due to different legal requirements in different countries and to historical custom and practice, leading to variations in basic assumptions such as the anticipated decommissioning strategy and end state of the site, and to different approaches to dealing with uncertainties. While attaining harmonisation across national approaches to cost estimation may be difficult to achieve, standardising the way decommissioning cost estimates are structured and reported will give greater transparency to the decommissioning process and will help build regulator and stakeholder confidence in the cost estimates and schedules.

This booklet highlights the findings of the NEA Decommissioning Cost Estimation Group (DCEG) which recently studied cost estimation practices in 12 countries.

As part of its activities, the Regulators’ Forum of the NEA Radioactive Waste Management Committee has been examining the regulatory criteria for the long-term performance of geological disposal. In this context, it organised a workshop entitled “Towards Transparent, Proportionate and Deliverable Regulation for Geological Disposal”, which served to verify current status and needs. Participants included regulators, implementers, policy makers, R&D specialists and academics. Themes addressed included duties to future generations, timescales for regulation, stepwise decision making, roles of optimisation and best available techniques (BAT), multiple lines of reasoning, safety and performance indicators, recognition of uncertainties and the importance of stakeholder interactions. The workshop highlighted the significant amount of work accomplished over the past decade, but also identified important differences between national regulations even if these are not in contradiction with international guidance. Also highlighted was the importance of R&D carried out on behalf of the regulator. In addition to the contributed papers, these proceedings trace the numerous discussions that formed an integral part of the workshop. They constitute an important and unique documentary basis for researchers and radioactive waste management specialists.

- Français: Uranium 2009 : Ressources, production et demande 
With several countries currently building nuclear power plants and planning the construction of more to meet long-term increases in electricity demand, uranium resources, production and demand remain topics of notable interest. In response to the projected growth in demand for uranium and declining inventories, the uranium industry – the first critical link in the fuel supply chain for nuclear reactors – is boosting production and developing plans for further increases in the near future. Strong market conditions will, however, be necessary to trigger the investments required to meet projected demand.

The “Red Book”, jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, is a recognised world reference on uranium. It is based on information compiled in 40 countries, including those that are major producers and consumers of uranium. This 23rd edition provides a comprehensive review of world uranium supply and demand as of 1 January 2009, as well as data on global uranium exploration, resources, production and reactor-related requirements. It provides substantive new information from major uranium production centres around the world, as well as from countries developing production centres for the first time. Projections of nuclear generating capacity and reactor-related uranium requirements through 2035 are also featured, along with an analysis of long-term uranium supply and demand issues.

VVER-1000 Coolant Transient Benchmark
Phase 2 (V1000CT-2) Summary Results of Exercise 1 on Vessel Mixing Simulation
English, 144 pages, published: 10/05/10

Recently developed best-estimate computer code systems for modelling 3-D coupled neutronics/thermal-hydraulics transients in nuclear reactors need to be validated against results from experiments and compared with each other to help understand how the different modelling methods adopted affect the accuracy of the simulation. This benchmark was set up for that purpose.

This report is one of a series covering benchmarks designed to test modelling methods for a range of transient scenarios in a VVER-1000 reactor. In this case, the transient is initiated by isolation of one steam generator causing asymmetric loop heat-up. The benchmark is based on experiments conducted at the Kozloduy nuclear power plant.
