Estimation of covariance of neutron cross section is important for quantitative evaluation of uncertainty of nuclear transmutation rate, radio activation, and so on. However, JENDL-4.0 provides only limited number of covariance data, and does not provide those of chloride nuclides which are used in the molten chloride salt fast reactor. In this study, we evaluated the covariance of neutron cross section of chloride nuclides by Monte Carlo method using T6.
