【 摘 要 】

Chinese government has put forward the strategy of developing nuclear power (NP), and now China has own the largest NP units that is under construction. The safety is foundation and premise of our country's nuclear sustainable development, we must strengthen the national surveillance on nuclear safety. Since every nuclear power plants has their own probabilistic safety analysis (PSA) model, and the precursor analysis methodology is a PSA-based methodology, this method can help to analyse how important the events will affect the nuclear safety, and identify those events which have larger safety importance. Therefore, the precursor analysis methodology can act as a valid method to nuclear safety surveillance to improve the surveillance level and efficiency. In this paper, the introduction of this methodology is given, and a detailed case study about one incident and the application result at one NPP is given.
