Kindai University Reactor (UTR-KINKI) is operated with HEU fuel, but nuclear data-induced uncertainty evaluation of criticality has not been sufficiently performed so far. In this study, eigenvalue calculations, sensitivity and uncertainty analyses were performed using SCALE6.2.4 to evaluate the uncertainty due to nuclear data for the effective multiplication factor.
