摘要
Abstract
Safety Classification of Structures,Systems and Components in Nuclear Power Plants(No.SSG-30)was issued by the International Atomic Energy Agency(IAEA).Starting from the two dimensions of safety function classification and design provision,the SSG-30 guidelines provide an operational method-ological framework for the safety classification of nuclear power plant structures,systems and components(SSCs),combining with factors such as the severity of failure consequences and item types.Based on SSG-30,this paper performs safety classification application research in major components of saturated steam generators in nuclear power plants.It discusses the safety classification of key parts such as the pressure boundary,internal components,and sealing assemblies,and the mechanical evaluation are carried out for the anti-vibration strip assembly and the sleeve support plate.The safety classification of nuclear steam gen-erators following SSG-30 can provide a reference for the classification and mechanical evaluation of nuclear power equipment,and is of great significance for the safe operation level of nuclear power units.关键词
