| 摘 要： | 采用严重事故最佳估算程序SCDAP/RELAP5/MOD3.4,建立了美国Surry核电站的详细计算模型,对完全丧失给水(TLFW)引发的堆芯熔化事故进行了研究分析.为准确预测压力容器内堆芯熔化的进程,给二级PSA提供可信的初始条件,计算中考虑了一回路压力边界的蠕变破裂失效,并评价了人为干预对堆芯熔化进程及事故后果的影响.

| Abstract: | Using the best estimate computer code SCDAP/RELAP5/MOD3.4,the detailed calculation models of USA Surry NPP are established and TLFW-induced core melt accident is analyzed.In order to predict the in-vessel core melt progression accurately and provide PSA-2 with the reliable initialization conditions,the creep rupture failure of primary loops pressure boundary is taken into account in code calculation.Besides,core melt progression and accident results with operator action are evaluated. |

| Keywords: | TLFW severe accident core melt progression creep rupture |
