OECD/NEA Data Bank E-Newsletter

No. 2, July 2008


The 17th Meeting of the Executive Group of the Nuclear Science Committee (Data Bank Management Committee) was held from 24 to 25 June 2008, chaired by Pierre D’hondt and attended by 23 delegates from member countries. The Data Bank activities and its budgets relative to 2007 and 2008 as well as planned activities and budgets for 2009 and 2010 were discussed and approved.
Like in the previous year, also this year’s meeting was prolonged by a half day to discuss a questionnaire on “evolution of the Data Bank to meet future challenges”, which is a continuation of last year’s discussion session on “the future of the Data Bank”. Also a special session on “new generation of computer codes in nuclear engineering” was held where three invited guest speakers from US, France and Japan have shared their common understanding on what is happening in the world of computer codes for nuclear science and technology and how they are expected to evolve in the future. A Workshop on this topic will be prepared for 2009.

On new generation of computer codes in nuclear engineering:

1. Nuclear data and tools

The following nuclear data libraries have recently been added to the evaluated nuclear data (EVA) database:

  • UK Heavy Element Decay Data library, UKHEDD-2.6;
  • UK Activation Product Decay Data library, UKPADD-6.8.
The EVA database contains a large number of evaluated data libraries, all in ENDF format; it can be consulted at www.nea.fr/html/dbdata/eva/evaret.cgi. More information on evaluated data libraries is available at www.nea.fr/html/dbdata/data/nds_eval_libs.htm.
Participants in the Joint European Fission and Fusion (JEFF) nuclear data evaluation project met on 21-23 May 2008 in Aix-en-Provence, France. Meeting participants reviewed feedback from the verification and validation of the current version of the JEFF data library and discussed evaluations to be incorporated into a future release of the library. A new release of JEFF-3.1.1/RDD, the radioactive decay data library, is now available on CD-ROM. The full documentation for the radioactive decay data library is currently being prepared for publication. More information is available at www.nea.fr/html/dbdata/projects/nds_jef.htm.
