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 is applied to the fusion-fission hybrid energy reactor. RELAP5 is used to model the hybrid energy reactor cladding, the primary circuit system, the partial secondary circuit system and the passive safety system. The main coolant pump card rotor accident and cold Transient Calculation and Analysis of Small Breakwater Pipe Accident. The calculation results show that the passive safety system can meet the safety requirements of the three selected reactor accidents and verify the feasibility of the passive safety system applied to the fusion fissile hybrid energy reactor. Passive residual heat removal system heat exchanger area increases, the envelope decay heat can be effectively derived; increase the core replenishment tank volume to increase the safety margin of the reactor has a significant effect.
