The Static Experiment Critical Facility (STACY) is being modified to achieve early first criticality to clarify criticality characteristics of fuel debris and is scheduled to start operation in May 2024 at the time of registration. The computations for the first criticality core configurations and some series of the experimental series. In this presentation, in addition to these studies, the status of the STACY modification will also be reported.
