RADIOGRAPHY INSPECTION TECHNOLOGY OF CPR1000 NUCLEAR POWER UNIT PRESSURIZER
This article takes the first in-service inspection of the 3rd Unit nuclear island pressurizer(PZR)radiography inspection of Ling Ao nuclear power station for example.It is introduced that the gamma radiographic inspection technology of CPR1000 nuclear power island PZR welds which include the cylinder weld,the tube welds and the head connection welds,the safe-end-welds of PZR tube,and the thermal sleeve,mainly focused on the exposure mode,the film layout and other content in each weld inspection.Meanwhile according to the site operating experience by the inspectors,it is summarized that the technical difficulties and key points which the PZR radiography inspection technology has.Combined with the related sections of the French design and construction rules for mechanical components of PWR nuclear Islands(the RCC-M standard)and the in-service inspection rules for mechanical components of PWR nuclear islands(the RSE-M specification),it makes analysis,calculation and discussion of the technical parameters and crucial details about the ray source selection,the identification of the film and the location markers,the focal length and the times of exposures at least,aiming the characteristics of the PZR ray inspection,which can provide reference method and the suggestion for the similar container radiography inspection.
