The JEFF Nuclear Data Library
A 3D rendition of the nuclide chart

The Joint Evaluated Fission and Fusion (JEFF) Nuclear Data Library is a collaboration between NEA Data Bank participating countries. The JEFF library combines the efforts of its different Working Groups to produce sets of evaluated nuclear data, for fission and fusion applications.

The JEFF project meets twice a year, in spring and fall, during the NEA Nuclear Data Week, in a 4 to 5 day technical programme, with the aim to promote co-operation between experimentalists, evaluators, producers and end-users of nuclear data.
