Post-Earthquake Comprehensive Inspection and Assessment of Performances of Nuclear Facility

In order to assess the influences of 5.12 Wenchuan earthquake on the nuclear facilities affiliated with Nuclear Power Institute of China, comprehensive inspection and assessment of those nuclear facilities were performed by different approaches such as inspection (RT, UT, PT and underwater video inspection), testing, analysis and confirmative review. It is the first time that this aspect of work was developped in China. The main inspection results and conclusions show that no damages to the research reactors and critical installations are found in the inspection range, and the three safety functions including safe shutdown, cooling and constrain of radiation release are ensured. It is recommended to continue site earthquake research work, determine site earthquake design base, revise emergency plan and develop special earthquake emergency plan, and so on.
