Seismic Margin Assessment for Qinshan Ⅱ Nuclear Power Plant
-
摘要: 根据国家核安全局(NNSA)"对国内运行核电厂全面开展抗震裕度评价"的要求,对秦山第二核电厂650 MW核电机组抗震裕度进行评价。结果表明:该型机组抗震裕度评价工作符合NNSA外部事件安全裕度评价工作方案和EPRI NP-6041-SL导则要求,确认该型核电机组具有一定的抗震安全裕度。Abstract: After the accident of Fukushima NPP, NNSA requires that Seismic Margin Assessment（SMA） should be implemented on all operational NPPs in China mainland. This paper describes the SMA process and result of 650 MW PWR unit in Qinshan II Nuclear Power Plant. It is shown that the SMA of 650 MW PWR unit satisfies the requirement of NNSA and complies with the EPRI-NP-6041 as well as the seismic safety margin.
