Research on Radiographic Testing of Steam Generator Tube-plate Welds on Nuclear Power Station

According to the special structure of the steam generator tube-plate welds in nuclear power station, a set of special inspection equipments were employed and corresponding special radiographic testing methods were developed.The best radiographic testing process for the steam generator tube-plate welds in CPR1000 nuclear power station was determined through experiments, thus providing technical support for the nuclear power station both pre-service and in service in the future.
