Abstract
The OECD-NEA High Priority Request List (HPRL) is a point of reference to guide and stimulate the improvement of nuclear data for nuclear energy and other applications, and a tool to bridge the gap between data users and producers. The HPRL is application-driven and the requests are submitted by nuclear data users or representatives of the user’s communities. A panel of international experts reviews and monitors the requests in the framework of an Expert Group mandated by the NEA Nuclear Science Committee Working Party on International Nuclear Data Evaluation Cooperation (WPEC). After approval, individual requests are classified to three categories: high priority requests, general requests, and special purpose requests (e.g., dosimetry, standards). The HPRL is hosted by the NEA in the form of a relational database publicly available on the web. This paper provides an overview of HPRL entries, status and outlook. Examples of requests successfully completed are given and new requests are described with emphasis on updated nuclear data needs in the fields of nuclear energy, neutron standards and dosimetry.
Highlights
The High Priority Request List (HPRL) for nuclear data has been established under the auspices of the Nuclear Energy Agency (NEA) in the 80s
The HPRL is managed by an Expert Group mandated by the NEA Working Party on International Nuclear Data Evaluation Cooperation (WPEC) working in close collaboration with NEA for administrative items and for the maintenance of the HPRL database, tools and web pages
The HPRL is driven by nuclear applications on the basis of requests for specific nuclear data improvement made by users
Summary
The High Priority Request List (HPRL) for nuclear data has been established under the auspices of the Nuclear Energy Agency (NEA) in the 80s. The list is a compilation of the highest priority nuclear data requirements from nuclear data users. The purpose is to stimulate and guide measurement, nuclear theory and evaluation programmes. The rationale for the current list was established in the 2000s [1, 2] on the basis of more stringent criteria for adopting new requests. The list provides an international point of reference for both nuclear data users and producers, and its effectiveness in stimulating new measurements, evaluations and verification actions to meet the needs is well established
