摘要: 为了评估非能动慢化剂余热排出系统的有效性,本文采用CATHENA程序模拟了正常工况及冷却水流失事故工况下非能动慢化剂余热排出系统的排热能力。通过对慢化剂冷却系统的模拟计算得到稳态运行结果,将该结果作为瞬态分析的初始条件计算了非能动慢化剂余热排出系统的排热能力,对计算结果进行了分析。分析结果表明,非能动慢化剂余热排出系统能够保证反应堆安全。Abstract: To evaluate the effectiveness of the Passive Moderator Residual Heat Removal System（PMRHRS）,CATHENA（Canadian Algorithm for Thermal hydraulic Network Analysis） code is used to simulate its cooling capability under normal condition and the lost of flow accident condition.And the result of steady state is obtained by the simulation and calculation for the Moderator Cooling System（MCS）,which is used as the initial value for the transient state analysis.The heat removal capability of the PMRHRS is then calculated and the result is initially analyzed to prove that the PMRHRS can keep the reactor safe.
