Nuclear Energy Data -- 2017
Nuclear Energy Data is the Nuclear Energy Agency's annual compilation of statistics and country reports
documenting nuclear power status in NEA member countries and in the OECD area. Information provided
by governments includes statistics on total electricity produced by all sources and by nuclear power, fuel
cycle capacities and requirements, and projections to 2035, where available. Country reports summarise
energy policies, updates of the status in nuclear energy programmes and fuel cycle developments. In
2016, nuclear power continued to supply significant amounts of low-carbon baseload electricity, despite
strong competition from low-cost fossil fuels and subsidised renewable energy sources. Three new units
were connected to the grid in 2016, in Korea, Russia and the United States. In Japan, an additional three
reactors returned to operation in 2016, bringing the total to five under the new regulatory regime. Three
reactors were officially shut down in 2016 -- one in Japan, one in Russia and one in the United States.
Governments committed to having nuclear power in the energy mix advanced plans for developing or
increasing nuclear generating capacity, with the preparation of new build projects making progress in
Finland, Hungary, Turkey and the United Kingdom. Further details on these and other developments are
provided in the publication's numerous tables, graphs and country reports.

Donnees sur l'energie nucleaire -- 2017
Les Donnees sur l'energie nucleaire, compilation annuelle de statistiques et de rapports nationaux de
l'Agence de l'OCDE pour l'energie nucleaire, presentent la situation de l'energie nucleaire dans les pays
membres de l'AEN et dans la zone de l'OCDE. Les informations communiquees par les gouvernements
comprennent des statistiques sur la production d'electricite totale et nucleaire, les capacites et les besoins
du cycle du combustible et, lorsqu'elles sont disponibles, des projections jusqu'en 2035. Les rapports
nationaux presentent brievement les politiques energetiques et les evolutions du cycle du combustible.
En 2016, l'electronucleaire a continue de generer des quantites importantes d'electricite en base faiblement
carbonee, et ce en depit de la forte concurrence des combustibles fossiles bon marche et des energies
renouvelable subventionnees. Cette meme annee, trois nouveaux reacteurs ont ete raccordes au reseau
en Coree, aux Etats-Unis et en Russie. Au Japon, trois reacteurs ont ete redemarres, ce qui porte a cinq
le nombre de tranches en exploitation repondant a la nouvelle reglementation en vigueur. Trois reacteurs
ont ete officiellement mis hors service en 2016 -- un aux Etats-Unis, un au Japon et un en Russie. Les pays
decides a inclure le nucleaire dans leur bouquet energetique ont poursuivi leurs projets de developpement
ou d'augmentation de la puissance nucleaire installee. Ainsi, les projets de construction en Finlande, en
Hongrie, au Royaume-Uni et en Turquie ont progresse. Le lecteur trouvera de plus amples informations sur
ces evolutions et d'autres developpements dans les nombreux tableaux, graphiques et rapports nationaux
que contient cet ouvrage.

Radiological Characterisation from a Materials and Waste End-State Perspective – Experience from Decommissioning Nuclear Facilities
English, published: 11/02/17
NEA#7373
Available online at: http://www.oecd-nea.org/rwm/pubs/2017/7373-rad-char-pers.pdf
Radiological characterisation is a key enabling activity for the planning and
implementation of nuclear facility decommissioning. Effective characterisation allows
the extent, location and nature of contamination to be determined and provides
crucial information for facility dismantling, the management of material and waste
arisings, the protection of workers, the public and the environment, and associated
cost estimations.
This report will be useful for characterisation practitioners who carry out tactical
planning, preparation, optimisation and implementation of characterisation to support
the decommissioning of nuclear facilities and the management of associated materials
and waste. It compiles recent experience from NEA member countries in radiological
characterisation, including from international experts, international case studies,
an international conference, and international standards and guidance. Using this
comprehensive evidence base, the report identifies relevant good practice and provides
practical advice covering all stages of the characterisation process.

NEA Workshop on Stakeholder Involvement in Nuclear Decision Making
Summary Report
English, 83 pages, published: 10/16/17
NEA#7302
Available online at: http://www.oecd-nea.org/hans/pubs/2017/7302-stakeholder-workshop.pdf
Because nuclear issues are embedded in broader societal issues such as the environment, energy, risk
management, health policy and sustainability, they can often generate considerable interest and concern.
Actors involved in the nuclear energy sector, including regulators, governments and licensees, share
the goal of reaching accepted, sustainable decisions and to ensure that the decision-making process
is transparent. Stakeholder involvement in decision making is today seen as an essential means for
improving decisions and for optimising their implementation.

In this context, the Nuclear Energy Agency (NEA) organised a Workshop on Stakeholder Involvement in
Nuclear Decision Making in January 2017, acknowledging that different countries and sectors may face
similar challenges and that sharing experiences and approaches could be useful. The workshop was an
opportunity to bring together experts with first-hand knowledge and experience in areas related to
nuclear law, regulatory practices, radiological protection, nuclear waste management, the deployment of
new nuclear facilities, extended operation of nuclear facilities, deployment of other energy technologies
and infrastructures, and social and traditional media.

This summary report attempts to capture the collective wisdom generated over three days of interaction.
It highlights some commonalities and differences in views and approaches, and identifies particular
lessons that can be applied to improve the strategy and practice of involving stakeholders in decision
making. Overall, the learning gained from this workshop can benefit governments and citizens alike.

Addressing Uncertainties in Cost Estimates for Decommissioning Nuclear Facilities
English, 66 pages, published: 09/28/17
NEA#7344
Available online at: http://www.oecd-nea.org/rwm/pubs/2017/7344-uncertainties-decom-cost.pdf
The cost estimation process of decommissioning nuclear facilities has continued to evolve in recent years, with a general trend towards demonstrating greater levels of detail in the estimate and more explicit consideration of uncertainties, the latter of which may have an impact on decommissioning project costs. The 2012 report on the International Structure for Decommissioning Costing (ISDC) of Nuclear Installations, a joint recommendation by the Nuclear Energy Agency (NEA), the International Atomic Energy Agency (IAEA) and the European Commission, proposes a standardised structure of cost items for decommissioning projects that can be used either directly for the production of cost estimates or for mapping of cost items for benchmarking purposes. The ISDC, however, provides only limited guidance on the treatment of uncertainty when preparing cost estimates. Addressing Uncertainties in Cost Estimates for Decommissioning Nuclear Facilities, prepared jointly by the NEA and IAEA, is intended to complement the ISDC, assisting cost estimators and reviewers in systematically addressing uncertainties in decommissioning cost estimates. Based on experiences gained in participating countries and projects, the report describes how uncertainty and risks can be analysed and incorporated in decommissioning cost estimates, while presenting the outcomes in a transparent manner.

National Inventories and Management Strategies for Spent Nuclear Fuel and Radioactive Waste
Extended Methodology for the Common Presentation of Data
English, 70 pages, published: 08/28/17
NEA#7371
Available online at: http://www.oecd-nea.org/rwm/pubs/2017/7371-spent-fuel-strategies.pdf
Radioactive waste inventory data are an important element in the development of a national radioactive waste management programme since these data affect the design and selection of the ultimate disposal methods. Inventory data are generally presented as an amount of radioactive waste under various waste classes, according to the waste classification scheme developed and adopted by the country or national programme in question. Various waste classification schemes have evolved in most countries, and these schemes classify radioactive waste according to its origin, to criteria related to the protection of workers or to the physical, chemical and radiological properties of the waste and the planned disposal method(s).

The diversity in classification schemes across countries has restricted the possibility of comparing waste inventories and led to difficulties in interpreting waste management practices, both nationally and internationally. To help improve this situation, the Nuclear Energy Agency developed a methodology that ensures consistency of national radioactive waste and spent fuel inventory data when presenting them in a common scheme in direct connection with accepted management strategy and disposal routes. This report is a follow up to the 2016 report that introduced the methodology and presenting scheme for spent fuel, and it now extends this methodology and presenting scheme to all types of radioactive waste and corresponding management strategies.

Sourcebook of International Activities Related to the Development of Safety Cases for Deep Geological Repositories
English, 64 pages, published: 08/21/17
NEA#7341
Available online at: http://www.oecd-nea.org/rwm/pubs/2017/7341-sourcebook-safety-cases.pdf
All national radioactive waste management authorities recognise today that a robust safety case is essential in developing disposal facilities for radioactive waste. To improve the robustness of the safety case for the development of a deep geological repository, a wide variety of activities have been carried out by national programmes and international organisations over the past years. The Nuclear Energy Agency, since first introducing the modern concept of the ?safety case?, has continued to monitor major developments in safety case activities at the international level. This Sourcebook summarises the activities being undertaken by the Nuclear Energy Agency, the European Commission and the International Atomic Energy Agency concerning the safety case for the operational and post-closure phases of geological repositories for radioactive waste that ranges from low-level to high-level waste and for spent fuel. In doing so, it highlights important differences in focus among the three organisations.

Recycling and Reuse of Materials Arising from the Decommissioning of Nuclear Facilities
A Report by the NEA Co-operative Programme on Decommissioning
English, 69 pages, published: 08/16/17
NEA#7310
Available online at: http://www.oecd-nea.org/rwm/pubs/2017/7310-recycle-decom.pdf
Large quantities of materials arising from the decommissioning of nuclear facilities are non-radioactive per se. An additional significant share of materials is of very low-level or low-level radioactivity and can, after having undergone treatment and a clearance process, be recycled and reused in a restricted or unrestricted way. Recycle and reuse options today provide valuable solutions to minimise radioactive waste from decommissioning and at the same time maximise the recovery of valuable materials. The NEA Co-operative Programme on Decommissioning (CPD) prepared this overview on the various approaches being undertaken by international and national organisations for the management of slightly contaminated material resulting from activities in the nuclear sector. The report draws on CPD member organisations’ experiences and practices related to recycling and reuse, which were gathered through an international survey. It provides information on improvements and changes in technologies, methodologies and regulations since the 1996 report on this subject, with the conclusions and recommendations taking into account 20 years of additional experience that will be useful for current and future practitioners. Case studies are provided to illustrate significant points of interest, for example in relation to scrap metals, concrete and soil.

SFCOMPO-2.0: International Database of Spent Nuclear Fuel Isotopic Assays
English, published: 07/17/17
NEA#7391
Available online at: http://www.oecd-nea.org/sfcompo/
SFCOMPO 2.0 is the NEA database of experimental assay measurements. Measurements are isotopic concentrations from destructive radiochemical analyses of spent nuclear fuel (SNF) samples, supplemented with design information for the fuel rod and fuel assembly from which each sample was taken, as well as with relevant information on operating conditions and design characteristics of the host reactors. SFCOMPO 2.0 contains data from 750 SNF samples coming from 44 reactors representing 8 different international reactor designs. SFCOMPO 2.0 was released online in June 2017.
SFCOMPO 2.0 has been developed by the NEA in close collaboration with Oak Ridge National Laboratory (ORNL). The data in SFCOMPO 2.0 has undergone an independent and iterative review process by the Expert Group on Assay Data of Spent Nuclear Fuel (EGADSNF), under the NEA Working Party on Nuclear Criticality Safety (WPNCS). The data have been reviewed for consistency with the experimental reports but have not been formally evaluated. Assay data evaluations are a multidisciplinary effort involving reactor specialists, modelling and simulation experts, and radiochemistry experts. Any errors in measurements, omissions or inconsistencies in the original reported data may be reproduced in the database. Therefore, it is important that any user of the data for code validation consider and assess the potential data deficiencies. The evaluation of assay data will provide a more complete assessment and may result in the development of benchmark specifications and measurement data in cases of high quality experiments.
SFCOMPO 2.0 contains only openly accessible, published experimental assay data. An online Java application of SFCOMPO 2.0 is available at www.oecd-nea.org/sfcompo.
