The concept of a nuclear data request list has a long history in applied nuclear science. The concept is that if requests from applied users of data are collected in a convenient location, it should provide a stimulus to measurers, modellers, and evaluators to undertake work that could lead to certain requests becoming satisfied. A revised High Priority Request List (HPRL) for nuclear data needed for applications has been in existence under the auspices of the OECD Nuclear Energy Agency (NEA) for several years. This list provides a point of reference for nuclear data stakeholders and developers and has led to many new initiatives in nuclear data measurement, evaluation and validation. Its effectiveness in stimulating new measurements, evaluations and verification actions required to meet the expressed needs is well established.
A standing expert group is essential to maintain the HPRL as a point of reference in nuclear data research and development. The expert group consists of at least three representatives from each data project: one from the data user, one from the evaluation and validation community and one from the experimental community. The expert group may have additional representatives from the IAEA Nuclear Data Section, as well as countries not represented in the above-mentioned projects.
The HPRL will reflect the actions undertaken by WPEC and will help guide future activities. The expert group will report to WPEC.
The expert group is responsible for managing the activities related to the High Priority Request List (HPRL) for Nuclear Data, in particular for guaranteeing that the entries are up-to-date and well-motivated by current interests in the field of nuclear energy and other nuclear applications. The expert group is also responsible for stimulating follow-up to the entries and collecting the feedback provided by any of the related activities that may further the resolution of a request. The expert group works mainly by electronic mail exchange. Physical meetings are held typically once a year.
The HPRL is organised as follows:
The request lists will be subjected to periodic review to monitor progress and determine whether each individual request should continue to be included in these lists.
