| 摘 要： | 在广东大亚湾核电站最终安全分析报告（FSAR）的基础上，对主给水管道破裂事故重新进行计算，并评价应急给水流量降低对电厂安全裕量的影响。结果表明，在应急给水系统提供的流量降低至41.8m^3/h时，主给水管道破裂事故仍然能满足验收准则的要求，并且尚具备一定的安全裕量。

| Abstract: | The major feed-water line break accident is re-analyzed, which is based on Guang dong Daya Bay nuclear power station final safety analysis report, to justify the impacts of the decreasing of auxiliary feed-water flow rate on the safety margin in Daya Bay. The results showed that the accident analysis can meet the demands of acceptance criteria with the auxiliary feed-water flowrate decreasing from 45m3/h to 41.8m3/h, and enough safety margin is still retained. |
