华龙一号保护系统架构研究

Analysis on Architecture Design of Reactor Protection System of Hualong 1 Nuclear Power Plant

核电厂反应堆保护系统是核电厂仪控系统的重要组成部分,执行重要的安全相关功能,保护三大核安全屏障完整性。本文以保护系统的相关设计原则为依据,研究比较了保护系统的通道逻辑不同冗余设计的可靠性,并提出华龙一号保护系统的架构方案。该方案所采用的独立性等设计原则可为今后三代保护系统架构设计提供一定参考。

The nuclear power plant reactor protection system is an important part of the instrument control system, and performs important safety functions to protect the integrity of the three nuclear safety barriers. By analyzing the relevant design principles and further determining the logical redundancy design of the reactor protection system, the architecture of the reactor protection system is proposed. The measure of independence of this architecture can be referred to when designing the reactor protection system of the 3 rd generation of the nuclear power plants.
