| 摘 要： | 选择一个典型的3环路压水堆作为参考对象,采用最佳估算程序RELAP/SCDAPSIM/MOD3.2建立了一个典型的3环路压水堆严重事故计算模型。分析了全厂断电(SBO)事故引发的堆芯熔化基准事故后,高压安全注射系统对该事故的缓解能力。敏感性分析表明,堆芯出口温度达到920 K时,采用卸压充水缓解措施可以有效地阻止堆芯熔化,维持堆芯长期处于稳定、安全状态。

| Abstract: | Taking a typical three-loop PWR as the reference plant and using the best estimate computer code RELAP/SCDAPSIM /MOD3.2, a representative three loops PWR severe accident calculation model is established and station blackout(SBO) induced core melt progression is analyzed. The mitigation capability of high-pressure safety injection system to severe accident is studied. The sensitivity calculation results show that the severe accident management strategy of bleed-and-feed cooling when the core outlet temperature reaches to 920 K can prevent the core damage effectively and the reactor core can achieve a long term safe stable state. |
