Purpose, scope and membership

The goal of the Working Party is to improve the quality and completeness of evaluated nuclear data available for use in science and technology and to promote the efficient use of available resources through international collaboration.

The Working Party will consist of up to five representatives of each of the following four nuclear data evaluation projects: ENDF (United States), JEFF (NEA Data Bank member countries), JENDL (Japan), RUSFOND/BROND (Russia), as well as up to five representatives of non-NEA nuclear data evaluation projects, such as CENDL or TENDL. The participation from projects in non-NEA member countries will be channelled through the Nuclear Data Section of the International Atomic Energy Agency (IAEA). At least one member of each group will be a representative of the nuclear data measurement community, and another one a representative of the nuclear application community.

A Working Party chairperson shall be elected for a two-year period, with possible yearly extensions; the guiding principle being an alternating chairmanship between the ENDF, JEFF, JENDL and RUSFOND/BROND projects. Eligible candidates are representatives of the evaluation projects in NEA member countries.

Objectives

The Working Party will promote the exchange of information on all nuclear data related topics (i.e., evaluation, measurement, theory/modelling and validation) and foster the adoption of best practices. The Working Party will provide a framework for co-operative activities between the participating projects. The Working Party will assess the needs for nuclear data improvements and address those needs by initiating joint evaluation and/or measurement efforts. The improvements will be reflected in all major evaluated data files and will gradually help eliminate inconsistencies in these files.

In the three-year period, the Working Party will set out to complete the following tasks:

The Working Party will liaise closely with other Nuclear Science Committee activities to ensure that data needs of nuclear science applications are properly addressed.
