Abstract 

The calculations of gamma-ray radiation of a set of radionuclides are needed nuclear data about gamma-ray spectra accompanied radioactive decay of radionuclides. The ENDF/B-VII.0 and JEFF-3.1.1 Decay Data Libraries are the modern evaluated nuclear data libraries for those nuclear data. This paper summarizes the processing codes which are created for processing evaluated decay data coded in the format “endf-6”. Some of the functions of these codes are: production of integral gamma-ray spectrum for a defined set of radionuclides. As an example the intercomparison of the gamma-ray radiation spectra of a spent fuel from the VVER-1000 reactor were made using the ENDF/B-VII.0 and JEFF-3.1.1 Decay Data Libraries.
