摘　　要：华龙一号核电机组应急柴油发电机1E(安全相关)属于反应堆保护系统(RPS)安全支持功能,其整体庞大复杂且分散、接口多。在进行设计时,常会出现设计遗漏现象;同时在验证这些功能时还会发生验证不全的问题。本文针对上述不足,系统分析华龙一号核电机组应急柴油发电机1E安全功能,并对这些功能予以重新定义和划分成不同子安全功能块,进而分别验证这些子安全功能块以确保其完整性。最后在实际工程应用中证明该方法的有效性,可为设计和验证提供指导。The emergency diesel generator 1E(safety-related)function of the Hualong No.1 nuclear power unit is part of the safety support function of the reactor protection system(RPS).Overall,the function is large,complex,dispersed,and has many interfaces.In the process of design,there are omissions.At the same time,the problem of incomplete verification could occur when verifying these functions.In view of the deficiencies,this paper systematically analyzed the safety functions of emergency diesel generator 1E of Hualong No.1 nuclear power unit and redefined and divided these functions into different sub-safety function blocks.Functional integrity was maintained by separately validating these sub-security functional blocks.Finally,the effectiveness of the method was verified by practical engineering applications,which could guide future design and verification.
