Abstract

Abstract

The containment is the last barrier to effectively prevent the leakage of radioactive materials after an accident in a nuclear power plant, and is one of the important facilities to ensure the safe and stable operation of a nuclear power plant, so its sealing performance is crucial. Nuclear power plant containment leakage testing is required during both commissioning and operation to test the containment sealing performance. The research progress was summarized from three perspectives: integrity leak rate testing, local leak rate testing, and other aspects involving containment leakage testing. The different methods of integrity leak rate testing and local leak rate testing were compared and the characteristics of the methods were summarized. In addition, a summary of component optimization, leak rate prediction and numerical simulation and software development related to containment sealing testing was presented. The shortcomings of the current containment leakage testing research were also analyzed, and the future directions of the containment leakage testing were discussed, which can provide relevant references for the containment sealing research and its development applications.
