摘要: 本文采用AFT Fathom软件分析了AP1000核电厂安全壳内置换料水箱(IRWST)的低压安注性能，分析了AP1000核电厂在压力容器直接注入管线双端断裂工况下事故后期的安全注射能力。分析结果表明，AP1000核电厂低压安注能力足以带出堆芯热量，并有较大的裕量。

Abstract: AFT Fathom code was used to calculate the low pressure safety injection of AP1000 nuclear power plant in-containment refueling water storage tank (IRWST). The safety injection performance of AP1000 nuclear power plant in the late period of direct vessel injection line (DVI) break accident was analyzed. The results show that the low pressure safety injection capability of AP1000 nuclear power plant meets the requirement of decay heat removing with reasonable margin.
