摘要
严重事故环境条件是设备鉴定和设备可用性评估的重要设计输入。本文针对CPR1000核电厂严重事故的环境条件进行计算分析,进行了典型的严重事故序列选取以及计算模型的处理,最终确定了安全壳内严重事故工况下的热工水力环境条件。同时本文也根据设备和仪表的具体位置细化了安全壳内的模型,进而得到设备所处具体隔间的特定环境条件分析方法。
Serious accident environmental condition is an important design input for equipment evaluation and equipment availability evaluation.In this paper,the environmental conditions of severe accidents in CPR1000 nuclear power plant are calculated and analyzed,the typical sequence of severe accidents and the treatment of calculation models are carried out,and the thermal hydraulic environmental conditions under severe accident conditions in the containment are finally determined.At the same time,this paper refines the model in the con⁃tainment according to the specific location of the equipment and instruments,and then obtains the analysis method of specific environmental conditions of the specific compartment where the equipment is located.
