核电厂烟囱监测道报警阈值研究

Research on Alarm Threshold Value of Stack Monitoring Channel for Nuclear Power Plant

根据相关标准规定,计算给出了“华龙一号”烟囱气溶胶、碘、低量程惰性气体、高量程惰性气体监测道的一、二级报警阈值.形成了烟囱监测道报警阈值的计算方法,解决了剂量约束条件、放射性物质沉积效应和高量程惰性气体监测道报警值计算依据的问题.仪表报警阈值的确定,可为烟囱监测道放射性测量方法选择、仪表选型提供参考.

According to relevant standards,we acquired the first and second alarm value of aerosol,iodine,low range and high range noble gas monitoring channel in H PR1000 reactor.This paper formed a complete,general and persuasive calculation method of stack monitoring channel alarm value.It solves the problems of dose constraint,radioactive material deposition effect and alarm value setting basis of high level noble gas monitoring channel.The instrument alarm threshold is used to guide the selection of measurement method and instrument type.
