核电厂仪表和控制系统法规标准体系概述

Overview of the Regulatory Standard Architecture of Instrumentation and Control System for Nuclear Power Plant

国内核电厂仪控设计遵循的法规标准基本从IEC及IEEE、IAEA等标准转化而来,经过多年的完善及技术积累,标准体系基本完善,内容基本完整,但仍存在部分标准版本较早,某些设计要点无参考标准、技术水平滞后的情况。本文对国内外现有的核电厂仪控系统设计依据的法规标准进行分析,总结出国内当前核电厂仪控系统设计的法规标准体系,用于指导华龙一号电厂初步设计工作。

The regulatory standards for instrumentation and control system design and implementation of nuclear power plants in China are basically transformed from IEC,IEEE,IAEA and other standards.After years of combing and technical accumulation,the standard architectural is basically perfect and the content is basically complete,but there are still some earlier versions of standards,some design points have no reference standards,and the technical level is lagging behind.In this paper,the existing domestic and foreign nuclear power plant instrument control system design based on the regulations and standards are analyzed,summed up the regulations and standards of the current unclear power plant instrument and control system design,which can be used to guide the preliminary design work of HPR1000 nuclear power plant.
