It introduces the current technology and equipment of sludge lancing and TV inspection used for cleaning tube plates for the secondary side of steam generators for CPR1000 units in China, including foreign object removal and acceptance criteria. It is concluded that the current sludge lancing and TV inspection technology and equipment could satisfy the requirements for cleaning and checking the tube plates of steam generators for CPR1000 units. Moreover, it provides some inspiration for the research and development of the sludge lancing and TV inspection technology and equipment which should be improved and developed in the future, whereas some limits of the current technology and equipment are pointed out at the same time.
