A review team comprised of experts from the Argentina, the Czech Republic, Finland, France, the Netherlands, Romania, Spain, Sweden, the USA and the IAEA, has completed an assessment of long-term operational safety at the Qinshan Nuclear Power Plant (NPP) Unit 1 in China.
The 12-member team, which began the review on 6 June, focused on aspects essential to the safe Long-Term Operation of Unit 1, which was put in commercial operation in 1991.
The team identified several good practices and performances at the plant that will be shared with the nuclear industry globally, including the organizational structure in place to support preparation for safe Long-Term Operation, comprehensive implementation of leak rate testing of containment isolation valves, and revalidation of time-limited ageing analyses of mechanical components.
The team informed the management to should make its Periodic Safety Review more comprehensive, establish and implement a comprehensive environmental qualification programme, and implement effective ageing management programmes for civil structures and components.
The design life of the plant’s Unit 1 is 30 years. China’s National Nuclear Safety Administration (NNSA) requires a Periodic Safety Review (PSR) to be performed every 10 years. The plant license expires in 2021. The plant intends to extend its operating lifetime to 50 years and submitted a license renewal application to NNSA in 2016.
