Global Evaluated Nuclear File (GENF/D): a decay data sub-library for radionuclide inventory applications

Decay data properties are regularly evaluated and re-evaluated, more frequently than are published evaluated decay nuclear sub-library. This work presents a procedure for generating an up-to-date decay library in ENDF-6 format, based on NUBASE2020, supplemented with the latest ENSDF data, through IAEA Livechart API, and extended with BetaShape, BrIcc, RadiationReport and GEF predictions. Called Global Evaluated Nuclear File (GENF/D), this decay sub-library covers 5502 isotopes, including 3511 ground states, and describes 8531 decay channels. Special care has been taken for spontaneous fission description, and using 2018 ENDF-6 format update, explicits the neutrino and anti-neutrino spectra. The former task led to the production of a new version of GEFY database for spontaneous and neutron-induced fission fragments database, based on NUBASE2020. Comparisons to the latest distributions of JENDL, ENDF/B and JEFF have been made, as well as as comparison to benchmarks of decay heat from shutdown reactors, with fissile and non-fissile materials.
