Currently China has 22 units of nuclear power reactors (NPPs) in operation, 27 units under construction. The first NPP Qinshan-I has been operated for 23 years, while the design life time is 30 years. In order to maintain safety operation of NPPs, it is very important to detect ageing effects, to understand related reduction in safety margins and to take actions before loss of integrity and functions. Ageing management program is set up for systems, structures and components important to safety to understand, monitor, and manage ageing effects in China. In addition, ageing, as one of safety factors, is reviewed during Periodical Safety Review. The regulation on licence renewal or long term operation should be decided by Chinese regulatory body in the near future.
