摘　　要：ATWS事故作为核电厂运行经验反馈所暴露的事故,核工业界对它的认识经历了一个长期的过程。对于商用压水堆核电厂,ATWS事故应对已形成一套完整的方法,而对于高功率研究堆,由于结构及特性与普通压水堆的差异,其ATWS事故要求也有所差异。本文回顾了ATWS事故的演变历程,分析了压水堆相关的标准规范,针对高功率研究堆,提出了ATWS事故分析的一般要求,对相关堆型安全分析工作的开展提供了条件。ATWS as an incident exposed by the feedback from nuclear power plant operating experience,the recognition of it by the nuclear industry has gone through a long process.The requirements for ATWS treatment and method for ATWS analysis were completely developed for nuclear power plants.For the requirement and analysis of ATWS,it is different between nuclear power plant and high power research reactor due to different structure and characteristics.The evolution of the ATWS in nuclear power plant was reviewed in the paper,based on which the standard specification for LWR was studied.For high power research reactor,the general requirements for ATWS analysis are put forward,which facilitates the implementation of safety analysis for related reactor type.
