摘要
Abstract
Containment is the last safety barrier between the"nuclear"and the public,and its tightness is very important.Nuclear power plants need to carry out containment tightness tests regularly.In order to improve the accuracy and efficiency of containment leakage detection in nuclear power plant,a new method of containment leakage location detection is explored,that is,by filling helium as a tracer into the containment according to a certain proportion,and making use of the distribution characteristics of the power plant radiation monitoring system around the containment plant,the leakage area can be detected by analyzing the amount of gas leaking from inside the containment.The feasibility of the method and the amount of helium are verified by field tests.The practice shows that the helium mass spectrometry leak detection method can be used in the containment leak detection of nuclear power plants.关键词
