摘要
采用CATHARE程序对直接注入(DVI)管失水事故(LOCA)试验进行了数值模拟。研究发现:DVI管LOCA中系统卸压、非能动安注、堆芯冷却等主要过程和物理现象得到了较好的模拟。一回路系统压力、堆芯补水箱(CMT)安注流量、安注箱(ACC)安注流量、内置换料水箱(IRWST)安注流量以及堆芯流体温度等参数的计算结果和试验数据符合较好。研究结果表明,CATHARE程序可以用于失水事故下非能动安注系统瞬态特性模拟分析。
The direct vessel injection （DVI） line loss of coolant accident （LOCA） experiment is simulated by CATIqARE code in this paper. The main processes and physical phenomena under DVI LOCA, such as system depressurization, passive injection and the cooling of core, are well simulated. The calculation results of primary system pressure, Core Makeup Tank （CMT） injection flowrate, Accumulator （ACC） injection flowrate, In-containment Refuelling Water Storage Tank （IRWST） injection flowrate and core fluid temperature agree well with the experimental data. It shows that the CATHARE code can be used to analyze the transient behaviors of passive injection system under LOCA.
