To realize the reasonable and effective maintenance of nuclear power plants, it is essential to optimize the maintenance scheduling management from the viewpoints of both safety and efficiency. As a fundamental study, we propose an inspection-process-scheduling model that minimizes the total number of inspections in a fast reactor. In this study, we formulate the inspection-process-scheduling problem as an integer programming problem. Computing the inspection-process schedules for a simplified fast reactor plant model, we verified that the proposed model can provide the optimal schedule automatically.
