摘　　要：在反应堆压力容器(RPV)内部安装辐照监督试样并定期取出试验可预测RPV服役状态,顺利提取辐照监督管是开展后续试验与评估工作的前提。围绕辐照监督管的提取,阐述了运输容器设计、制造与验证,运输容器在进入核岛前的安装与调试,辐照监督管提取及放置,运输容器包装四个方面的技术方案,并以某CPR1000机组为案例介绍了实践过程中的注意事项,为国内其他类似核电机组的辐照监督管提取提供参考。Irradiation surveillance capsules are installed in the reactor pressure vessel(RPV)and extracted regularly for experiments to predict the service status of the RPV.Hence,the smooth extraction of irradiation surveillance capsules is a prerequisite for subsequent experiments and evaluation.In this paper,four following technical solutions are elaborated around the extraction of irradiation surveillance capsules:①design,manufacture and verification of the shipping containers,②the installation and debugging of the shipping containers before entering the nuclear island,③the extraction and placement of the irradiation surveillance capsules,and④the packaging of the shipping containers.A CPR1000 unit is used as a case to introduce the matters needing attention in the practice process,and provide a reference for the extraction of irradiation surveillance capsules for other similar nuclear power units in China.
