摘要: 为了解决非能动慢化剂余热排出系统的不稳定性,本文对原系统结构设计进行了更改,并采用CATHENA程序模拟了在失流事故工况下改进后的系统排热能力。对模拟计算的结果分析表明,改进后的非能动慢化剂余热排出系统能够保证反应堆安全,并且消除了系统中的不稳定性。Abstract: To avoid the fluctuation of the Passive Moderator Residual Heat Removal System(PMRHR) of TACR,this paper improves the system structure and uses CATHENA(Canadian Algorithm for Thermal hydraulic Network Analysis) code to simulate its cooling capability under the condition of lost of flow accident.The results show that the improved system can keep the reactor safe and reduce the instability in light water loop.
