【摘要】 在研究稳压器汽腔小破口失水事故过程物理现象的基础上,对北京核电厂模拟培训中心模拟器中的反应堆冷却剂系统数学模型进行了改进,将两相流模拟分支加入到该系统模拟程序中去,得到了满意的模拟效果。文中给出了改进前、后模拟效果的对比,以及改进的结果与三里岛事故记录的对比。更多还原

【Abstract】 The original mathematical model of the reactor coolant system (RCS) of the simulator in Beijing Nuclear Power Plant Simulation Training Center has been evaluated. On the study of the physical phenomena during the pressurizer vapour space SBLOCA, the two phase flow simulation branch has been incorperated in RCS simulation program. The comparisons of the simulation results for the original model and improved model with the record of the TMI accident are presented. It is shown that simulating effects is satisfactory.更多还原
