Abstract: Ageing of System, Structure, and Components (SSCs) can have impacts on the safety and performance of nuclear power plants. Proactive plant life management is a key element to ensure long term safe, economic and reliable operation of nuclear power plants. Ageing must be systematically taken into account throughout the full plant’s lifetime. In China, since two old nuclear power plants of Qinshan-I and Daya Bay are approaching their design life, it is a great concern in China how to establish an effective ageing management program for the both plants. In addition, operating experience accumulated from the both plants should be learned and reflected to the new-built plants. In this paper, the proactive plant life management recommended by International Atomic Energy Agency (IAEA) is first summarized and then explain briefly how this IAEA recommended approaches are applied the current plant life management activities in China.
