摘　　要：将非能动安全系统应用于聚变-裂变混合能源堆,使用RELAP5对混合能源堆包层、一回路系统、部分二回路系统和非能动安全系统进行建模,对主冷却剂泵卡转子事故和冷管段小破口失水事故进行瞬态计算和分析研究。计算结果显示,该非能动安全系统能够满足选取的3种反应堆事故的安全要求,验证非能动安全系统应用于聚变-裂变混合能源堆的可行性。非能动余热排出系统热交换器的面积增大后,能有效地导出包层衰变热;增大堆芯补水箱的容积对增大反应堆安全裕度有明显效果。The passive safety system was applied to the fusion-fission hybrid energy reactor and a RELAP5 model was developed to represent the primary loop, partial secondary loop and the passive safety system components. The transient calculation and research were conducted for stuck pump accident, the SBLOCA on cold leg. The results indicate that the passive safety system can ensure the safety of fusion-fission hybrid energy reactor in the selected reactor accidents and it is feasible to apply the passive safety system to fusion-fission hybrid energy reactor. The decay heat can be exported effectively while the flow area of the heat exchanger of the PRHRs was optimized. Increasing the volume of CMT is of great significance for the reactor safetv margin.
