摘要
核电厂运行经验表明,在核电厂应急堆芯冷却系统、安全壳排热系统以及余热排出系统等安全系统中不凝气体的积聚可能会导致系统不能执行其既定的安全功能。美国在20世纪80年代便对不凝气体积聚的问题进行了研究。本文阐述了不凝气体对核电厂安全系统的影响,并介绍了美国对不凝气体积聚问题的研究进展及现状,主要包括在NRC发布的GL-2008-01中的主要内容和核电厂的响应情况、有关阻止和管理系统内气体积聚的指导文件(NEI 09-10)以及AP1000核电厂针对不凝气体积聚所采取的措施。
It is indicated by operation experiences that the accumulation of noncondensable gas in safety system such as emergency core cooling system（ECCS）,containment spray system and decay heat removal system in the nuclear power station,will lead to the system can not perform designed safety function,which was studied by USA in the 1980 s. This article discusses the noncondensable gas how to influence nuclear power system,and also introduces the relevant research status in USA mainly including the main content of GL2008-01 published by NRC and the respond situation from nuclear power station,the guideline（NEI 09-10）for preventing and managing the accumulation of noncondesable gas inside the system and the measures for accumulation of noncondesable gas by AP1000 nuclear power station.
