The JEFF library combines the efforts of its different working groups to produce a common set of evaluated nuclear data, mainly for fission and fusion applications. The JEFF project meets twice a year, in autumn and spring. The next edition of the Nuclear Data Week will take place on 17-21 November 2025, and will host both the JEFF Co-ordination Group and the JEFF technical sessions.
