Abstract
Estimation of covariance of the neutron cross sections of the long-lived fission product (LLFP) nuclides is important for the design of an innovative LLFP transmutation system utilizing a fast reactor. Estimation of uncertainty of the cross-section data produces quantitative evaluation of errors of the reactor constants such as nuclear transmutation rate. We estimated the covariances of neutron cross sections of LLFP nuclides (79Se, 93Zr, 99Tc, 107Pd, 129I, and 135Cs) using the nuclear data evaluation code system T6.
