摘要：在运核电站模拟仪控系统面临技术老化和物理老化的问题，采用数字化DCS技术对在运核电站通用仪控系统的大范围升级改造具有技术复杂、影响面广、投资大，项目执行周期长、单次实施时间紧（只能在机组大修期间实施等特点。从改造必要性、仪控系统设计基准、数字化仪控技术特点、仪控系统功能分析、仪控系统安全分级、仪控系统架构方案，仪控系统数字化改造全生命周期各关键阶段的工作任务、仪控系统数字化改造风险分析等几方面对在运核电站模拟仪控系统数字化升级改造需重点关注的间题进行了初步分析和论述。在此基础上，结合国外核电站仪控系统数字化改造的经验和教训，对
我国在运核电站模拟仪控系统的数字化改造升级策略提出建议。关键词：数字化，改造；生命周期；规划

Abstract: The operating nuclear power plants are subject to ageing and obsolete problems of the analogue I&C systems, The large scope I&.C upgrading project based on the DCS technology has the following challenged characteristics; the complicated technology, the broad impacts, the big investment and the long implementation period, This document gives a preliminary introduction and analysis from the aspects including the motives for the upgrade, I&C design base, the digital technology characteristics, I&C function analysis, I&.C safety classification, I&C architecture, life-cycle-management mission for the related stages. Considering the experiences and lessons learned from the similar I&C upgrade projects in foreign nuclear power plants, the conclusion and recommendation is given for I&C modernization based on the digital technology.
