始发事件是铅基反应堆确定论安全分析和概率安全评价的起点和基础,对反应堆优化设计和安全运行具有重要指导作用。本文基于小型自然循环铅基快堆SNCLFR-100当前的设计方案,参考其他先进快堆始发事件选取经验,以广义“堆芯熔化”作为顶层目标事件,采用主逻辑图(MLD)方法推导其内部始发事件,最后得到一组较完整的内部始发事件清单。本文研究可为自然循环铅基快堆安全分析工作的开展提供理论依据。

The initiating events, as the starting point and basis for the deterministic safety analysis and probabilistic safety assessment of the lead-cooled fast reactor (LFR), provide important guidance on the design optimization and safe operation of reactors. This paper, based on the current design scheme of the small natural circulation lead-cooled fast reactor SNCLFR-100 and by reference to the experience of selecting initiating events of other advanced fast reactors, with the generalized 'core melting' taken as the top target event, provides the i...
