福岛第一核电站发生事故后，为了防止再次发生严重事故，对提高核安全提出了很高的要求。基于纵深防御概念，改进建立了核电厂系统安全性的疲劳评估新方案。本研究以日本核电厂的疲劳失效分析为基础，探讨如何重构核电厂疲劳评估的总体设计，以确保系统安全。根据福岛第一核电站事故后，疲劳管理在核电站长期安全运行方案中的新作用，对我们目前存在的疲劳评估问题进行了研究，以审查大设计。
After Fukushima Daiichi NPP accident, the improvement of nuclear safety is highly requested in order to prevent re-occurrence of severe accident. New scheme of fatigue evaluation to confirm system safety in NPPs is enhanced to be established based on Defense in Depth concept. This study focuses on the direction to reconstruct Grand Design of fatigue evaluation to ensure system safety based on fatigue failure analysis of Japanese NPPs. The issues of fatigue evaluation we have now is investigated in order to review Grand Design on the basis of new role of fatigue management in plant long term safe operating scheme that is required after Fukushima daiichi NPP accident.
