压水堆核电厂严重事故下堆芯熔融物的冷却研究

The Research on Molten Corium Coolability Measures for the PWR Severe Accident

堆芯熔融物的冷却和捕集在严重事故后长期的进程对安全壳完整性有很重要的影响,本文综述了核电厂特别是先进核电厂在堆芯熔融物冷却和保持方面的设计,并进行简要分析比较。

The corium melt coolability is perhaps the most vexing issue impacting containment performance in the long term after a severe accident. This paper described the severe accident mitigation concept in respect of corium melt coolability and retention, especially for advanced light water reactor plant. At last the mitigations were briefly reviewed.
