Abstract
The main function of the control rod guide tube (CRGT) is to guide the rod cluster control assembly (RCCA), its integrity can make sure that the RCCA’s drop-time meets the requirements of nuclear safety. This paper puts forward two kinds of visual inspection schemes by analyzing the inspection environment and common defects. A more conservative and stable scheme was selected because of the strict requirements of the inspection environment for foreign materials and radiation. The equipment is applied in the nuclear power plant and the results of visual inspection have guiding significance for the replacement of 6 relevant CRGTs.
