核电厂保护系统多样性设计应用研究

Research on the Application of Protection System Diversity Design in Nuclear Power Plant

为保证核电厂可靠性和安全性,应对数字化仪控系统的共因故障风险,保护系统必须充分考虑多样性的设计以满足纵深防御的原则。本文介绍了中国核能发展的概况以及多样性设计要求,并以保护系统架构为基础,详细地对核电厂保护系统的多样性分类和实现方法进行分析和研究。

In order to ensure reliability and security of nuclear power plant, and cope with the common cause failure of digital IC system, protection system design must consider diversity design to meet requirements of DefenseDepth principle adequately. This article addresses the development of China nuclear power and diversity design requirement. Based on protection system architecture, this paper analyzes and studies in detail the classification and realization methods of diversity in protection system of nuclear power plant.
