The Joint Evaluated Fission and Fusion (JEFF) Nuclear Data Library is a collaboration between NEA Data Bank participating countries to produce a common set of evaluated nuclear data, mainly for fission and fusion applications. The JEFF project meets twice a year, in the autumn and spring, for a JEFF Nuclear Data Week with the aim of promoting co-operation between experimentalists, evaluators, producers and end-users of nuclear data.
The second Nuclear Data Week of 2023, held in the last week of November, featured 12 sessions, nearly 70 presentations and over 130 attendees. It included a diverse range of sessions, providing a comprehensive exploration of nuclear data applications. It also incorporated industry feedback through a new session, reflecting an effort to engage proactively with industrial stakeholders, garner insight on the JEFF library and broaden the scope of nuclear data research. The NEA Data Bank aims to strengthen and integrate this industry-oriented component into future editions of the event.
The event culminated on Friday with the presentation by the co-ordination group of the strategic roadmap for the release of JEFF-4 in 2024. The group outlined plans for the accompanying documentation, underlining the commitment to transparency and comprehensive information dissemination. This forward-looking approach shows a commitment to maintaining the JEFF library as a reliable and updated resource for the nuclear data community.
