General Description of Fission Observables: JEFF Report 24; NEA Data Bank (June 2014).
The Joint Evaluated Fission and Fusion (JEFF) Project is a collaborative effort among member countries of the Data Bank to develop a reference nuclear data library. The JEFF library contains a number of different data types, including neutron and proton interaction data, radioactive decay data and fission-fragment yield data. The General fission (GEF) model is based on novel theoretical concepts developed to model low energy nuclear fission with a demonstrated capability to calculate fission yields and associated quantities for a large range of nuclei and excitation energies. This report describes the recent development and validation of the GEF model within the framework of the JEFF Project with the objective to further improve fission yield data in future releases of the JEFF library. As a result, most of the fission observables can be generally predicted by GEF with an accuracy that complies with the needs of nuclear energy applications.
The fission yields data described in this report are available in the GEFY-4.2 library for spontaneous and neutron-induced fission.
