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 through its different subgroups.
