In order to validate the latest version of Japanese Evaluated Nuclear Data Library, JENDL-5, released in December 2021, some benchmark tests were conducted with integral experiments that contribute to the research and development of fast reactors and ADSs. As the results, improvement from JENDL-4.0 was confirmed in the benchmarks of Na/void reactivity worth and fission rate ratios of TRU to Pu-239 measured in the JAEA fast critical assembly (FCA) experiments.
