An NEA workshop to examine the results obtained by participants in the ISP-48 (international standard problem) exercise was held on 6-7 April 2005 in Lyon, France. Workshop participants also assessed current practices and the state of the art with respect to the calculation of the response of structures under severe accident conditions. The results of this assessment will be used to develop a consensus on these calculations and identify gaps in present knowledge.
The Information System on Occupational Exposure (ISOE) is a unique worldwide programme to review, promote and co-ordinate international co-operative undertakings for the radiological protection of workers at nuclear power plants. It also serves as a forum for discussing occupational exposure management issues and is the repository for the world's largest database on occupational exposure from nuclear power plants.
The ISOE Steering Group met at NEA headquarters on 17-18 November 2004. The group agreed to migrate the ISOE occupational exposure database to a fully web-based system; access to the system will be restricted to ISOE members. The group also discussed current operational radiological protection issues. These included the increasing need for benchmark studies of exposure data and approaches to such major jobs as the replacement of reactor vessel heads in nuclear power plants. The ISOE Steering Group will next meet in Tokyo, Japan in 2005. More information is available at www.oecd-nea.org/jointproj/isoe.html.
The NEA Expert Group on the Implications of ICRP Recommendations (EGIR) met on 29-30 November 2004 at NEA headquarters to develop a set of proposed wording changes to the new draft ICRP recommendations in order to make them more applicable to the needs of the recommendations' users. The Chair of the International Commission on Radiological Protection (ICRP), Professor Roger Clarke, participated in the meeting and was able to clarify many of the issues raised by group members as well as learning more about their needs and concerns. The final report from the EGIR will be forwarded to the ICRP for consideration and will be discussed at the March 2005 meeting of the NEA Committee for Radiation Protection and Public Health. The ICRP recommendations are now expected to be approved in 2006, a year later than previously anticipated. This is to allow for the incorporation of input from the EGIR and other such groups. More information is available at www.oecd-nea.org/rp/egir.html.
The NEA Nuclear Science Committee has established an expert group to study very high burn-up fuel cycles in light water reactors. This expert group met on 22-23 November 2004 at NEA headquarters to discuss progress on its report on the potential benefits of very high burn-up (60–100 gigawatt-days per tonne) fuel cycles. The report will cover both the technical and economic aspects of such high burn-up fuel cycles, identifying problem areas but not attempting to solve them. It is planned to publish the report in early 2006.
