OECD/NEA Data Bank e-newsletter

Issue No. 8, March 2011

Our deep sympathy goes to all those who have suffered as a result of the recent earthquake and tsunami in Japan. Even though we have seen the pictures on our television screens, it is still difficult to truly comprehend how terrible these experiences must have been. We send our very best wishes to all those involved in the rescue, recovery and rebuilding efforts.

1. Nuclear data and tools

Experimental Data – The EXFOR database contains experimental data from neutron and charged particle induced reactions. It is maintained by the international network of Nuclear Reaction Data Centres (NRDC), which includes the NEA Data Bank. Data recently published in peer-reviewed journals have been compiled in the following EXFOR entries (this list is limited to new entries from the NEA Data Bank and does not show all recent updates to EXFOR).

Evaluated Data – The Joint Evaluated Fission and Fusion (JEFF) project is a collaborative effort among NEA Data Bank participating countries to compile, maintain and develop a reference nuclear data library for use in different energy applications. Following the adoption by the French nuclear industry of the latest version of the JEFF library (JEFF-3.1.1, released in 2009), the JEFF collaboration efforts now concentrate on the development of its next major release, the JEFF-3.2 library, which will implement more and further improved nuclear data evaluations and is expected for official release in about 2 to 3 year’s time.

The NEA Working Party on International Nuclear Data Evaluation Co-operation (WPEC) provides a worldwide framework for co-operative activities between major nuclear data evaluation projects. Two WPEC subgroups recently completed their work and the final reports are now available. Subgroup 24 was established to develop a methodology for the production of covariance data in the fast neutron region. The report describes the different approaches and compares results obtained with existing nuclear reaction codes. Subgroup 30 focused on improving the accessibility and the quality of the Experimental Nuclear Reaction Data (EXFOR) database. The report describes the translation process from EXFOR into more user-friendly tabulated data files, as well as the various methods developed to verify and correct the contents of the database.

Note for users of DVDs sent out by the NEA Data Bank:

The CD-ROM and DVD robot used at the NEA Data Bank to produce copies of the information it distributes has been upgraded. DVDs are produced for large packages with dual layers. The result of this upgrade and modification is that compatibility problems might arise with operating systems and/or DVD-readers older than 12 years, i.e. released before 1997. Users experiencing problems with old DVD readers should either request information on CD-ROM or upgrade their readers.

Criticality Safety

The 2010 edition of the International Criticality Safety Benchmark Experiments Project (ICSBEP) handbook is now available. The evaluated criticality safety benchmark data are given in nine volumes. These volumes span over 55,000 pages and contain 516 evaluations with benchmark specifications for 4,405 critical, near critical, or subcritical configurations, 24 criticality alarm placement / shielding configurations with multiple dose points for each, and 200 configurations that have been categorized as fundamental physics measurements that are relevant to criticality safety applications.

Reactor Systems

The first meetings of four new Experts Groups under the Working Party on Scientific Issues of Reactor Systems were held at NEA Offices in the first week of February. The groups are:

The roles of EGRFP, EGRTS and EGRPANS will include helping to develop the Integral Experiments Databases IFPESINBAD and IRPhE, respectively. Work has started on reviewing the contents, structure and future requirements of each database. For IRPhE a study is being made on the development of a database tool to allow users to search for experiments of particular interest, similar to the DICE tool already available for ICSBEP. The next issue of the IRPhE handbook is due in April/May 2011.
