核电厂安全仪控系统的机架不确定度数据获取方法

摘要

At present,there are some law and standards about setpoints and uncertainty for safety-related instrumentation in China nuclear power plants.ln the description,the basic data for setpoints and uncertainty is from the vender.WlTH the tendency of equipments localization in nuclear power plant,more and more equipments are developed local y.How to obtain these basic data becomes a key question.This paper from the point of the rack in safety l&C system,describes about the basic data for l&C system rack,and how to obtain these data.%目前，国内针对核电站安全级通道的整定值和不确定度计算已有一些法规和标准要求。其中对整定值和不确定度计算的基础数据，一般的描述为从供货商处获得，没有明确的方法。针对目前核电站设备国产化的大趋势，越来越多的设备已经进行了国产化生产制造。新设计的国产设备如何获得这些基础数据也成为了关键问题。从安全系统的机架角度出发，介绍了仪控系统机架的基础不确定度数据及其获取方法。
