摘要
介绍了压水堆核电站冷却剂环境影响疲劳寿命问题,包括环境影响疲劳寿命问题的背景和发展、影响一回路主设备材料疲劳寿命的主要因素和机理、环境影响疲劳寿命的主要评价方法和环境修正系数的使用,并对国内核电站环境影响疲劳寿命问题的解决提出了建议。
Pressurized water reactor coolant environment assisted fatigue（EAF）issues are discussed in this paper,including backgrounds and progress of EAF,main factors affecting material fatigue life of primary system equipment and related mechanisms,main evaluation method and usage of environmental correction factor.Some proposals on how to deal with the EAF issues in domestic reactors are also given.
