JEFF-3.3
The Joint Evaluated Fission and Fusion File (JEFF) is an evaluated library produced via an international collaboration of NEA Data Bank participating countries.
JEFF-3.3 is a thorough update of the neutron, decay data, fission yields, dpa and neutron activation libraries in the EAF format, with neutron thermal scattering files for 20 compounds. Special sub-libraries for incident alphas, deuterons, gammas, helium-3, protons and tritons have been contributed by the TENDL-2017 library and adopted as part of the JEFF-3.3 release. JEFF-3.3 was officially released on November 20, 2017.
Recent updates
- [December, 2019]: JEFF-3.3.1 Activation file The update labeled JEFF-3.3.1 version of the activation data library in EAF format is now fully consistent with TENDL-2017. All cross-sections included in the activation data library were extracted and processed from TENDL-2017 and successfully benchmarked with CCFE’s V&V suite. They are released in the two EAF energy group structures : 2011 and 709 groups, for all isotopes available in the TENDL library. The previous JEFF-3.3 (pointwise) version, included cross-sections from pure TALYS calculations for the following nuclides: \(^{1,2,3}H\), \(^{3,4}He\), \(^{6,7}Li\), \(^{10,11}B\), \(^9Be\), \(^{12,13}C\), \(^{14,15}N\), \(^{16,17}O\), \(^{19}F\), \(^{232}Th\), \(^{233,235,238}U\) and \(^{239}Pu\).
