NEA Nuclear Data High Priority Request List - HPRL

The NEA Nuclear Data High Priority Request List (HPRL)  is a compilation of the most important nuclear data requests that have been rigorously reviewed by the NEA Working Party on International Nuclear Data Evaluation Co-operation (WPEC) . The purpose of the list is to provide a guide for those planning measurement, nuclear theory and evaluation programmes.
