摘　　要：针对2015年Davis-Besse 1号机组流体加速腐蚀导致管道破裂并引起手动紧急停堆事件,从直接原因、根本原因、次要原因三个方面进行事件反馈原因分析,并对Davis-Besse事件采取的改进措施和引发的经验教训进行总结。为避免Davis-Besse事件的重发,对国内类似电站机组进行共模特性分析,并提出了几点具体的措施和建议。Aiming at the incident that the flow accelerated corrosion model results in steam line failure and manual reactor trip at Davis-Besse Nuclear Power Plant in 2015, the paper analyzed the event reasons from direct cause, root cause and contributing cause, and the corrective action and event triggered lessons were summarized. To avoid recurrence of Davis-Besse event, similar power plant units are co-model analyzed, and several measures and recommendations have been proposed.
