| Abstract: | AP1000 reactor vessel upper closure head adopts integrated design,the core instrument tubes are set on the top of the RV closure head,and the bottom mounted instrument penetrations are removed from RV bottom.Based on the requirements of ASME code for RV closure head during pre-service inspection,this paper mainly introduced full-range automatic inspection equipments and site application of NDT technique,which was developed on the basis of introduction and digestion.In addition,in order to lay a foundation for the improvement of in-service inspection technology,the problems encountered during the pre-service inspection process of equipments and inspection technology were discussed. |
