NEA provides support for new stage of nuclear safety initiative

The OECD Nuclear Energy Agency (NEA) is supporting a new stage of an important international initiative, the Multinational Design Evaluation Programme (MDEP). The MDEP was set up to share the resources and knowledge accumulated by national nuclear regulatory authorities during their assessment of new reactor designs, with the aim of improving both the efficiency and the effectiveness of the process. More information is available at www.oecd-nea.org/news/2006/2006-05.html.

Nuclear safety

A specialist meeting on seismic probabilistic safety assessment of nuclear facilities was held on 6-8 November 2006 on Jeju Island, Republic of Korea. The meeting provided an opportunity to review recent advances in the methodology and practical application of seismic probabilistic safety assessments and seismic margin analyses to nuclear installations. The workshop outcomes will be described in a forthcoming technical report. More information is available at www.oecd-nea.org/nsd/workshops/seismicrisk/index.html.

Nuclear science

An NEA expert group formed to review the current status of nuclear science research and test facilities and the likely future requirements worldwide for such facilities met on 30-31 October 2006 at NEA headquarters in Paris, France. During their meeting the expert group examined the new research and test facilities database (RTFDB) and discussed a draft version of the group's final report. A test version of the database has been installed on the NEA website to allow members of the NEA Nuclear Science Committee and facility owners to review the data and to provide feedback. More information is available at www.oecd-nea.org/science/egrfs/.


Data Bank


Nuclear data services

Participants in the Joint Evaluated Fission and Fusion File (JEFF) project met to evaluate the progress of the JEFF, European Fusion File (EFF) and European Activation File (EAF) projects on 20-22 November 2006 at NEA headquarters in Paris, France. Nearly 60 participants, mostly from Europe, discussed the current status of ongoing nuclear data benchmarks, processing initiatives and decay data and fission yield libraries. A meeting of the processing code NJOY user group was also held in connection with the JEFF meetings. More information is available at www.oecd-nea.org/dbdata/projects/nds_jef.htm.

Thermochemical Database Project (TDB)

All four main reviews included in the third phase of the TDB project continue to make steady progress. The review of thorium is currently being peer reviewed and is expected to be ready for publication in early 2007. The state-of-the-art report on the thermodynamics of solid solutions will be ready for publication in the first half of 2007. The review of tin is well advanced and sections on solid and gases are now ready for peer review. The review of iron, covering the key species for Fe(II) and Fe(III), is expected to be ready for peer review by September 2007.

During its meeting on 26-27 October 2006 at NEA headquarters in Paris, France, the management board of the third phase of the TDB project approved a one-year extension (from 1 February 2007 to 31 January 2008) of the current TDB project agreement and to begin planning during 2007 for a new phase of the project. The tentative start date for the new phase of the project is 1 February 2008. More information is available at www.oecd-nea.org/dbtdb/.
