二代加核电堆内构件实堆辐照监督结构研究

Research on In-Pile Irradiation Structures of Second-Generation Plus Nuclear Power Plants

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。

Material radiation ageing should be considered in the aging analysis of the reactor internals of nuclear power plants. At present, there is still no material irradiation data of reactor internals at home. Operating history shall be considered for different reactor types or specific rectors. For the purpose of understanding the effect of material radiation ageing on the reactor internal accurately, a new scheme of in-pile irradiation structures is put forward. © 2015, Editorial Office of Nuclear Power Engineering.
