摘　　要：福岛事故后,《核动力厂设计安全规定》(HAF102—2016)明确引入了设计扩展工况的概念,提出将设计扩展工况纳入设计范畴,以进一步提高核动力厂的安全性。论文遵照HAF102-2016法规要求,参考国际上对设计扩展工况的研究,提出一套适用于ACP100模块式小堆堆芯未损伤设计扩展工况(DEC-A)的分析方法,开展ACP100模块式小堆DEC-A工况研究。研究表明,ACP100模块式小堆针对各类DEC-A工况均有相应的缓解措施和应对能力,保障了模块式小堆的安全性。论文形成的DEC-A工况选取及分析方法也为其他核电厂的DEC-A研究提供了思路和参考。After the Fukushima accident,the Design Safety Regulations for Nuclear Power Plants(HAF102-2016)explicitly introduced the concept of design extension condition,and proposed to include the design extension condition into the design category,so as to further improve the safety of nuclear power plants.In accordance with the requirements of HAF102-2016 regulations and referring to international studies on design extension conditions,this paper proposes A set of analysis methods applicable to DEC-a design extension condition(UNdamaged design extension condition)of ACP100 modular small reactor core,and carries out dec-a condition study of ACP100 modular small reactor.The research shows that ACP100 modular small heap has corresponding mitigation measures and coping capabilities for various DEC-A working conditions,which ensures the security of the modular small heap.The working condition selection and analysis method of DEC-A developed in this paper also provide ideas and references for dec-a research of other nuclear power plants.
