采用反应堆热工水力系统计算分析程序CATHARE分别对模块化小型堆ACP100原型反应堆和非能动余热排出系统(PRHRS)试验装置发生全厂断电事故(SBO)进行模拟,计算结果表明:PRHRS试验装置采用的模拟方法可以较好地反映ACP100反应堆原型的主要热工参数,失真度在可接受范围以内。
The reactor thermal hydraulics calculation and analysis program (CATHARE) was used to simulate the power failure accident (SBO) of modular mini-reactor ACP100 prototype reactor and passive residual heat removal system (PRHRS) respectively. The results show that the PRHRS test device adopts The simulation method can well reflect the main thermal parameters of ACP100 reactor prototype, the distortion is within the acceptable range.
