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.]]> Mon, 13 May 2013 00:00:00 +0200 http://www.oecd-nea.org/tools/publication?id=7067 7067 Mon, 06 May 2013 00:00:00 +0200 http://www.oecd-nea.org/tools/publication?id=7144 7144 Fri, 19 Apr 2013 00:00:00 +0200 http://www.oecd-nea.org/tools/publication?id=7093 7093 Les principaux articles de ce numéro sont : « À la recherche de l’excellence : présentation et analyse des Principes de conduite des exportateurs de centrales électronucléaires », « La réponse du Canada à l’incident du MCP Altona : cadre réglementaire relatif à l’exportation d’uranium », « Conflits de lois liés à la participation de la Suisse au régime de responsabilité civile de la Convention de Paris » et « L’impact des protocoles additionnels et des garanties renforcées sur l’Agence internationale de l’énergie atomique et les États ».]]> Thu, 18 Apr 2013 00:00:00 +0200 http://www.oecd-nea.org/tools/publication?id=7149 7149 Mon, 25 Mar 2013 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=7092 7092 Feature articles in this issue include: "A common high standard for nuclear power plant exports: overview and analysis of the Nuclear Power Plant Exporters’ Principles of Conduct"; "The MCP Altona incident: the Canadian regulatory response and framework for the export of uranium"; "Conflict of law issues related to Switzerland’s participation in the Paris Nuclear Third Party Liability Regime"; and "The impact of the Additional Protocol and Strengthened Safeguards: effects on the International Atomic Energy Agency and on states".]]> Fri, 22 Mar 2013 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=6988 6988 Fri, 01 Mar 2013 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=7079 7079

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 65 000 pages and 549 evaluations with benchmark specifications for over 4 700 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 Water-moderated Square-pitched U(6.90)O2 Fuel Rod Lattices with 0.67 Fuel-to-water Ratio experiments (see front cover) that were performed by a team of experimenters at Sandia National Laboratories between 2009 and 2012.]]> Mon, 31 Dec 2012 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=7077 7077
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.]]> Mon, 31 Dec 2012 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=7089 7089
The OECD Nuclear Energy Agency (NEA) has prepared this publication in co-operation with the government of Japan to share Japan’s recent experience in implementing its nuclear liability and compensation regime. The material presented in the publication should provide valuable insights for those wishing to better understand the regime applied to compensate the victims of the accident and for those working on potential improvements in national regimes and the international framework for third party nuclear liability.]]> Mon, 31 Dec 2012 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=7120 7120 Mon, 31 Dec 2012 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=6990 6990 Mon, 31 Dec 2012 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=6991 6991 Mon, 31 Dec 2012 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=7124 7124 Cette étude offre une mise à jour opportune sur l’évolution du rôle de l’autorité de sûreté, et les éclairages apportés pourront aider les nombreux pays qui envisagent ou préparent l’entreposage ou le stockage des déchets radioactifs dans des installations en subsurface ou plus grande profondeur.

While it focuses on the developments in waste management and disposal, the trends it describes are probably relevant throughout the nuclear field.]]> Mon, 31 Dec 2012 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=6885 6885
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.]]> Fri, 21 Dec 2012 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=7054 7054 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.]]> Wed, 19 Dec 2012 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=7129 7129 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.]]> Tue, 18 Dec 2012 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=7131 7131 Mon, 17 Dec 2012 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=7056 7056 Fri, 09 Nov 2012 00:00:00 +0100 http://www.oecd-nea.org/tools/publication?id=7066 7066 Mon, 05 Nov 2012 00:00:00 +0100
