The accident sequences and mathematical model of core melt (CM) was established, then quantitative analysis is performed.
并以陆奥号核动力商船为例,运用事件树分析技术,对SGTR事故进行了安全分析,得出了事故后可能导致堆芯熔化的事故序列,确定了堆芯熔化数学模型,并进行了定量化分析。
The calculated results show that core melt progression is fast and most of the core material melt and relocated to the lower plenum.
结果表明,压水堆发生大破口失水事故时,堆芯熔化进程较快,大量堆芯材料熔化并坍塌至下腔室,反应堆压力容器下封头失效较早,且主回路冷段破口比热段破口更为严重。
In order to predict the in-vessel core melt progression accurately and provide probabilistic safety assessment(PSA) level 2 with the reliable initialization conditions,the creep rupture failure of primary loops pressure boundary was taken into account in code calculation.
为准确预测压力容器内堆芯熔化的进程,为二级概率安全评价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。
