Keywords:JENDL-5, CASMO5, Validation, Criticality experiment analysis, PIE analysis

The CASMO5 neutron data library based on JENDL-5 is generated and validated by comparison with the conventional ENDF/B-VII.1 library analyzing TCA criticality experiments and Takahama-3 PIE data. In the present library, such data as cross section, decay data, fission yield, etc based on ENDF/B-VII.1 are replaced by those of JENDL-5 as much as possible. As a result of the TCA experiment analysis, keff with the JENDL-5 library is slightly greater than those with the ENDF/B-VII.1 library for all cases analyzed. This tendency is also observed by same analysis using MVP3.0. For the PIE analysis, C/E values of nuclide inventory are almost comparable to those with the ENDF/B-VII.1 library and improved for Cs-134.
