摘要
丧失给水事故发生后,若相关安全保护系统失效,将导致一回路丧失热阱,从而使堆芯发生裸露,进一步发生锆水反应产生氢气,氢气进入安全壳有可能发生燃烧或爆炸,产生的高温高压将威胁安全壳的完整性。文章通过M AAP4程序计算分析了丧失给水引发的严重事故后氢气控制系统的消氢能力。
After loss of feed water accident, if the safety features fail to start up, the primary will loss heat sink, which may lead core uncover to generate hydrogen by Zirconium-Water Reaction. The hydrogen release to the containment could cause deflagration or detonation ,which would produce both high thermal and pressure loads on the containment. This paper use MAAP4 to analyze the hydrogen removal capability after the severe accident induced by loss of feed water.
