摘要

为提升华龙一号安全水平,响应最新法规要求,幵充分吸收福岛核事故经验反馈,华龙一号设计了蒸汽发生器二次侧非能动余热排出系统(PRS),用于应对和缓解全厂断电叠加辅助给水汽动泵失效事故和给水完全丧失事故,实现事故后堆芯余热的长期有效导出。本文通过理论分析全厂断电叠加辅助给水汽动泵失效事故和给水完全丧失事故,确认了设计方案的有效性。
        To improve the safety level of HPR1000, respond to latest regulatory requirements, and fully absorb the experience feedback of the Fukushima nuclear accident, passive residual heat removal system is designed for HPR1000, to mitigate SBO superimposed turbine-driven auxiliary feedwater system failure and total loss of feedwater, and to realize long term effective removal of residual heat from the reactor core after accident. This paper verified the effectiveness of the design scheme by theoretical analysis of SBO superimposed turbine-driven auxiliary feedwater system failure and total loss of feedwater.
