Keywords:KUCA, substitution reactvity worth, Thorium core, U233, HEU, Nuclear data

In engineering discussions of the feasibility of Thorium reactor systems, it is important to validate of nuclear data such as Th232, U233 and so on. In this study, measurment of U233-HEU substitution reactivity worth in KUCA was carried out and the obtaind value was compared with numerically calculated value using each nuclear data library.
