纵深防御与多样性准则贯穿于核电厂安全有关的所有活动中,仪表和控制系统作为核电厂的重要组成部分也不例外. 基于NUREG/CR 6303对纵深防御和多样性的技术要求,研究和总结了两者之间的关系,并结合核电厂仪表和控制系统结构,分别从纵深防御应用以及多样性在系统间和系统功能中的应用等方面进行分析,认为在设计过程中引入纵深防御与多样性准则是非常必要的.通过在功能和系统设备中设置多重屏障和多样化,可以有效地提高核电厂的安全性能,并且防止潜在故障的发生.

Depth-in-defense and diversity criterion are throughout all the activities related to the safety of nuclear power plant, as one of the important components of the nuclear power plant, instrument and control ( I&C) systems are not excluded. Based on NUREG/CR 6303, the technical requirements of depth-in-defense and diversity, the relationship between them is researched and summarized. In accordance with the structure of I&C system of nuclear power plant, the application of depth-in-defense and the application of diversity among systems and systematic functions are analyzed respectively;it is considered that introducing depth-in-defense and diversity criterion in design process is necessary. By setting up multiple barriers and diversification in functions and system equipment may effective improve the safety performance of nuclear power plant, and prevent occurrence of potential failures.
