Fission nuclear data is essential information for the realization of safe nuclear power systems, but especially in terms of fission yield, the energies for which nuclear data is prepared are extremely limited. In this study, we are attempting to improve the accuracy of fission nuclear data for isotopes and energy regions with scarce experimental values using machine learning. Additionally, we have verified and evaluated the impact of the newly constructed fission nuclear data on reactor physics. This presentation will outline these series of efforts.
