摘要:国产三代自主化核电项目华龙一号的设计特点之一是采用能动与非能动相结合的安全设计
理念,其中,为对抗全厂断电事故,增设了二次侧非能动余热排出系统(PRS)。非能动系统运行
特殊,并且华龙一号的二次侧非能动余热排出系统是国内大型核电厂中的首次应用,因此,需要建
立一套非能动余排系统的设计方法。本文针对华龙一号PRS的设计容量展开研究,摸索出一套论证
方法,从安全功能出发,抓住影响余排系统设计容量的主要因素,确定其设计容量为1.8% FP,并
探讨了非能动余排系统安全功能拓展后的设计容量,为该系统的后续工程具体方案设计提供基础。

Abstract:One of the design feature of self-designed generation ⅢNuclear Power Plant -
Hualong one is the combination of active and passive safety concept. The extension
secondary passive residual heat system is designed for station blackout. Considering the
unique performance of the passive system and the first application of the secondary passive
residual heat system in the large-scale Nuclear Power Plant,the methodology of
determination of passive residual heat system design capacity is necessary. In this paper,the
methodology of design capacity for the PRS is developed. From the safety function,the
design capacity of Hualong one PRS is 1.8% full power and the design capacity of function
extension PRS is also discussed,that provide the basis for the subsequent design.
Key words:Passive Residual Heat System;Design Capacity;Hualong one
