内部事件概率安全评价在核电厂设计中的应用

Applications of Internal Events Probabilistic Safety Assessment in Nuclear Power Plants’ Design

文章阐述了在核电厂设计阶段开展概率安全评价(PSA)的目的、方法及流程。讨论了如何从评估结果出发,给出新建核电厂的设计薄弱点和设计改进建议。文中通过在国内新建核电厂上开展的一些PSA应用案例,展示了内部事件PSA在核电厂设计过程中发挥的重要作用。

This paper describes the purpose,approach and process of performing the probabilistic safety assessment(PSA)in the NPP design.Design vulnerabilities,recommendations of design improvements for new plants are discussed from the aspect of evaluation results.Based on some PSA applications implemented in domestic new NPPs,the paper demonstrates the importance of internal event PSA in the NPP design.
