JENDL Decay Data File 2015

This newly released file, "JENDL Decay Data File 2015" (JENDL/DDF-2015), contains decay data for 3,237 nuclides ranging from the lightest elements including H-1 and n, up to Rf(Z=104). The data of 1,284 FP nuclides remain unchanged from JENDL/FPD-2011, and those of the newly added 1,953 nuclides are taken from ENSDF and transformed into ENDF-6 format. This file can be used to evaluate the production of radioactive isotopes (RIs) for use in decommissioning nuclear reactors, as well as in wider applications, e.g. the estimation of RI production by accelerators.
