In order to achieve both safety and economic efficiency of a nuclear power plant, it is necessary to realize rational maintenance based on characteristics of the plant. The fast breeder prototype reactor, Monju, spent most of the year for the maintenance. It is important to identify causes of the prolonged maintenance of Monju and to investigate countermeasures for implementation of rational maintenance of a next fast reactor. In this study, causes of the prolonged maintenance of Monju during reactor cold s...

Analysis of issues related to maintenance period in the fast breeder prototype reactor Monju (2) Analysis of plant maintenance plan

To achieve the reasonable and effective maintenance of nuclear power plants, it is essential to optimize the aging management from the viewpoints of both safety and efficiency. We propose an inspection-process-scheduling model that minimizes the number of inspection activities in a fast reactor. In this study, we formulate the inspection-process-scheduling problem as mixed integer programming and 0- integer programming problem....

Fundamental Study on Optimal Scheduling of Inspection Process for Fast Reactor

Maintenance scheduling is currently manually handled, which is a time-consuming process because of the large number of components and constraints that must be taken into account when creating a schedule. Besides, to develop next-generation power plants with excellent operability, it is necessary to make it possible to evaluate operability and maintainability in advance at the design stage. Our objective is to develop and implement an automatic scheduling system using the mathematical technique of Operations...
