核电反应堆堆内构件在反应堆延寿分析中需考虑设备材料的辐照老化。目前国内尚无堆内构件材料的具体辐照数据,同时针对不同堆型及具体的机组,由于其运行使用也不尽相同,对于具体机组的辐照老化分析,还需考虑其具体的功率运行史,因此,为了较为准确地了解辐照老化对堆内构件使用的影响,本文提出了堆内构件实堆辐照监督结构方案。 Nuclear reactor components in the reactor life-span analysis of materials to be considered radiation aging equipment. At present, there is no specific irradiance data for the material of the internals in China. At the same time, for different reactor types and specific units, their operation and use are different. For the irradiation aging analysis of specific units, the specific power operation needs to be considered Therefore, in order to know more accurately the influence of radiation aging on the use of components in the reactor, this paper presents a scheme of real-time radiation monitoring structure of in-reactor components.
