Non-uniformity of the composition is an issue when evaluating fuel debris's criticality characteristics. Critical experiments using the modified STACY are planned to validate the criticality effects of the non-uniformity. In this presentation, the results of the critical experiment their experimental core arrangements have large non-uniformity effects, and their experimental analyses are shown.
