The Joint Evaluated Fission and Fusion File (JEFF) Nuclear Data Library Project is a collaboration between NEA Data Bank participating countries. 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 November 2021 Nuclear Data Week hosted the JEFF Co-ordination Group meetings and a selection of JEFF technical sessions. 

Please note that these meetings were hybrid, with both in-person and online attendance options. The conference location will be the prestigious Château de La Muette, in the 16th arrondissement of Paris. Note that a "Pass Sanitaire" was asked of all participants coming to the premises. More information on practical details were provided at the time.

Detailed agendas for the sessions will be made available in due course through this webpage. Please note that the schedule might change.

* The participation to the Co-ordination Group meeting is by invitation only.
