摘要
在工程设计中,蒸汽管道破裂(SLB)事故的分析是针对偏离泡核沸腾(DNBR)计算,而对燃料元件综合性能并不进行分析,这样的分析方法过于保守。本文基于SLB事故特征,建立了燃料元件相应的计算分析模型,通过对SLB事故的模拟,分析了CF3燃料元件在热态零功率蒸汽管道破裂(HZPSLB)事故下的堆内行为,结果显示CF3燃料元件包壳在该事故下不会发生屈服,进而验证了CF3燃料元件的安全性。
In the engineering design,the SLB accident analysis focused on the computation of DNBR,but no fuel rod performance in reactor was analyzed.This method is too conservative.In this paper,the model were built based on the fuel rod performance and the characteristics of SLB accident,and a new method was adopted to analyze the CF3 fuel rod performance by model the HZP SLB accident process.The calculation results showed that the cladding did not yield,and the safety of the CF3 fuel rod were verified.
