Abstract Uncertainty evaluation of transmutation characteristics due to errors in neutron capture cross sections of LLFP nuclides is an important issue in the design of an innovative long-lived fission product (LLFP) transmutation system utilizing fast reactors. By using the error of neutron capture cross section estimated using a T6 system, the uncertainty of the reaction rate of the LLFP nuclides has been analyzed on the transmutation target assembly enabling high transmutation efficiency.
