OECD/NEA Data Bank E-Newsletter

No. 3, October 2008

On 1 October, a questionnaire concerning the Data Bank was sent out to the delegates of member countries (all members of the Executive Group of the Nuclear Science Committee: the Data Bank management committee). This questionnaire was prepared for the first step in the revision process of the Data Bank part of the next NEA Strategic Plan, a new six-year plan.

The Physor'08, International Conference on the Physics of Reactors, organised by PSI in collaboration with NEA, was held in Interlaken, Switzerland from 14-19 September 2008. Many NEA related works especially in relation with NSC were presented and discussed. As to the nuclear data conference track, the recent release of new versions of the major evaluated data libraries showed a significant performance improvement, nevertheless data improvements are still needed for the data of actinides particularly minor-actinide cross-sections and fission spectra. Renewed interest was also observed in covariance matrices. Many industrial applications of Nuclear Data and calculation methods in reactor physics for power plants were presented and discussed. Specific sessions were devoted to benchmark studies carried out under the aegis of OECD/NEA.

1. Nuclear data and tools

A Nuclear Reaction Data Centres (NRDC) meeting was held in Obninsk, Russia on 22-25 September 2008. The topic of quality control of EXFOR and CINDA, experimental and bibliographical databases, was discussed extensively. The development of user feedback pages was decided as a way of identifying EXFOR entries containing possible errors. This will be helpful for creating a new data base that only contains correct EXFOR entries, which will be a useful tool for the evaluators of nuclear data.

2. Processed data libraries

Recently acquired or tested application data libraries:
