摘要: 使用MELCOR 2.1程序建立ACP1000自然循环模型,选取全厂断电叠加辅助给水丧失严重事故(TMLB'),分析主冷却剂管道热段和蒸汽发生器(SG)传热管自然循环现象,采用蠕变失效模型评价主冷却剂系统(RCS)部件失效时间。结果表明,压力容器(RPV)出口接管比有裂纹的SG最热传热管先失效。

Abstract: The natural circulation model of ACP1000 Nuclear Power Plant is built using MELCOR 2.1. This paper analyzes the natural circulation phenomena in the hot leg and steam generator tube by selecting TMLB’ accident, and uses the cumulative creep damage to determine the relative creep-rupture timing in the reactor coolant pressure boundary components. The results showed that RPV outer pipe would be failed earlier than the flawed steam generator hottest tube.
