摘要
根据核电站设计总体要求,特别是对仪控系统可用性和可靠性的要求,通过分析核电站中系统、设备及其功能的安全分级,解析现代数字仪化控系统(DCS)的技术特点。结合实际在建核电站中不同DCS总体技术方案设计实施过程中的差异,从满足核电站安全运行以及安全评审相关法规标准的需求出发,阐明核电站中不同安全分级的系统和设备对DCS总体方案设计实施的影响。
By analyzing the safety classification for the systems and functions of nuclear power plants based on the general design requirements for nuclear power plants,especially the requirement of availability and reliability of IC systems,the characteristics of modern DCS technology and IC products currently applied in nuclear power field are interpreted.According to the requirements on the safety operation of nu-clear power plants and the regulations for safety audit,the effect of different safety classifications on DCS design in nuclear power plants is analyzed,by considering the actual design process of different DCS solu-tions in the nuclear power plants under construction.
