Working Party on International Nuclear Data Evaluation Co-operation (WPEC)

33^rd Meeting

13-14 May 2021

The Working Party on International Nuclear Data Evaluation Co-operation (WPEC) was established to promote the exchange of information on nuclear data evaluations, measurements, nuclear model calculations, validation, and related topics, and to provide a framework for co-operative activities between the participating projects. The Working Party assesses the needs for nuclear data improvements and addresses those needs by initiating joint evaluation and/or measurement efforts throught its different sub-groups.
