摘　　要：依据HAF 102《核动力厂设计安全规定》法规5.5节要求,核电站安全级DCS需要进行设备鉴定。国内外通常是对通用平台进行鉴定。当平台应用到不同核电厂环境时,IEC/IEEE 60780-323虽然认可基于已完成的型式试验结果通过分析进行鉴定,但没有提出分析方法的具体要求。国外采用的分析法仅限于同一堆型不同机组间,以及系统架构及功能基本一致的情况,缺乏适用于不同堆型和架构的通用方法。通过对标准和核级分布式控制系统(DCS)特性的深入研究,创新性地提出了6维度分析模型,创建了基于鉴定试验机理的影响分析技术。该方法成功应用到二代、三代和四代堆型的多个核电厂安全级数字化DCS设备鉴定工作中,确保了鉴定结论有效,保证了核电厂的安全性。该研究成果为核电厂数字化DCS应用于不同堆型和应用环境的设备鉴定提供了一种通用的分析方法,具有较高的借鉴价值。According to the requirements of HAF 102"Nuclear Power Plant Design Safety Regulations"Section 5.5,safety grade DCS of nuclear power plant needs to carry out equipment qualification.Common platforms are usually qualified at home and abroad.While the IEC/IEEE 60780-323 approves analysis based on the results of completed type tests when the platform is used in different nuclear power plant environments,it does not provide specific requirements for analysis methods.The analysis method adopted abroad is limited to the same type of different units,and the system architecture and function are basically the same,so there is a lack of general method applicable to different types and structures.Through the in-depth study of the characteristics of standard and core distributed control system(DCS),a 6-dimensional analysis model was proposed innovatively,and an impact analysis technique based on the identification test mechanism was created.The method has been successfully applied to the safety grade digital DCS equipment identification of the second,third and fourth generation nuclear power plants,which ensures the validity of the identification conclusions and the safety of nuclear power plants.The research results provide a general analysis method for the equipment identification of the digital DCS system applied to different reactor types and application environments in nuclear power plants,which has a high reference value.
