摘　　要：福岛核事故后,极端灾害可能引发的核电厂相关设备大范围损伤情景下的事故处理策略成为核安全必须关注的问题之一。本研究针对台山核电厂EPR机组的大范围损伤情景,选取具有代表性的全厂断电工况,开展事故敏感性分析。结合台山核电厂的系统特征及电厂移动设备的配置,给出该类事故情景下用于堆芯损伤状态控制及缓解的反应堆冷却剂系统注水策略的相关缓解行动要求和关键时间节点,以有效缓解事故进程。在此分析基础上制定了EDMGs反应堆冷却剂系统注水策略。After the Fukushima accident,the accident treatment strategy under extensive damage conditions of nuclear power plant's related equipment caused by extreme disasters has become one of the issues that nuclear safety must pay attention to.In this paper,considering extensive damage of EPR in Taishan nuclear power plant,the representative scenarios of station black out are selected to perform sensitivity analysis,based on the system characteristics of the nuclear power plant and the configuration of the mobile equipment of nuclear power plant,relevant mitigation action requirements and key time of reactor coolant system water injection strategies for core damage control and mitigation under accident scenarios,so as to effectively mitigate the accident progression.On this foundation,reactor coolant system water injection strategies of EDMGs have been formulated.
