摘要
“华龙一号”采用全新177堆芯设计,与传统堆芯布置存在一定差异,仅在概率安全分析评价中基于工程判断确定瞬态事件卡棒停堆成功准则有一定的局限性。本研究利用堆芯核设计程序建立“华龙一号”全寿期燃料循环堆芯模型,采用堆芯停堆次临界度分析方法,研究不同卡棒数量对卡棒停堆成功准则的影响,并开展“华龙一号”瞬态事件卡棒成功准则验证。研究结果表明:本研究提出的压水堆核电厂瞬态事件卡棒停堆成功准则分析方法是合理可行的,“华龙一号”瞬态事件N-3卡棒停堆成功准则是有效的。
There are 177 fuel assemblies in HPR1000 reactor core(hereinafter referred to as“177 core”),which is different from the traditional core layout.In the probabilistic safety analysis for HPR1000,the control rod stuck shutdown success criteria in transient events evaluation is determined based on engineering judgment,which has certain limitations.In this paper,the core model of the HPR1000 full-life fuel cycle is established by using the core nuclear design code,and the effect of different control rod stuck number on the control rod stuck shutdown success criteria is studied by using the core shutdown subcriticality analysis method,and the verification of the control rod stuck success criteria in the transient event of HPR1000 is also carried out.The research results show that the analysis method of the control rod stuck shutdown success criteria for the transient event in PWR nuclear power plant is reasonable and feasible,and the N-3 control rod stuck shutdown success criteria in the transient event of HPR1000 is effective.
