| 摘 要： | 严重事故的预防和缓解是新一代核电厂的重要安全问题。本文主要讨论核电厂严重事故研究和管理中确定严重事故主导事故序列时应考虑的准则问题,包括定性和定量准则以及准则相应的意义。以此为基础,本文整理形成一套推荐中国核电厂进行严重事故主导序列筛选时采用的准则,并以1000MW非能动先进压水堆(AP1000)标准设计为研究对象进行应用尝试。分析表明,严重事故选取准则应从定性和定量两方面阐述。从定性的角度,严重事故的选取应根据核电厂状态划分,在超设计基准事故范围内,选取可能导致堆芯损伤和安全壳旁路,并且在后果上具有包络性的事故序列。从定量的角度,应确定导致核电厂严重事故风险的绝对筛选值和相对筛选值,同时还要包络陡边效应,补充确定论分析和工程经验的成果结论。根据建议准则选取的AP1000严重事故主导序列与其概率安全分析报告中进行重点分析的严重事故序列基本吻合。

| Abstract: | Severe accidents prevention and mitigation is an important safety issue for new generation Nuclear Power Plant (NPP). This paper mainly focuses on the severe accident dominant sequences screening criteria when performing NPP severe accident management and study,including qualitative and quantitative criteria and their understanding. On this basis,a set of severe accident dominant sequence screening criteria is recommended for Chinese nuclear power plant severe accident study. Using this set of criteria to A... |
