A new nuclear data library JENDL/ImPACT-2018 has been developed aiming at study for nuclear transmutation system of high-level radioactive waste. Due to possible creation of a lot of secondary products including unstable nuclei, the nuclear reaction data have been evaluated with improving predictability of theoretical calculations.
