The antineutrinos which are emitted in a process of beta decay of fission products in reactors are called reactor neutrinos. Reactor neutrinos are key to obtain the information of inside of the reactor and spent fuel from the perspective of nuclear security and safeguards, and these are also the signal of neutrino oscillation. This study aims to optimize the nuclear data for calculating the energy spectra and fission yields of reactor neutrinos based on summation calculation of fission products.
