Risk Analysis on Safety Injection Test of PWR Nuclear Power Plant
-
摘要: 在压水堆核电厂安注试验期间,可能出现稳压器满水及主蒸汽发生器(SG)高高、低低液位等问题。本文分析了安注试验的风险及应对措施;针对某核电厂进行安注试验时稳压器热态标定液位计满量程问题,对试验过程进行分析,并总结出安注试验中应注意的问题。Abstract: During the safety injection（SI） test in the PWR nuclear power plant,full water in pressurizer and high-high level,low-low level in SG may take place.This paper analyzes the risks and response measures in the SI test.Focusing on the full scale problem of pressurizer thermal calibration level gauge in the SI test of nuclear power plant,the test process is analyzed and the problems that should be noted in the SI test are summed up.
