Abstract

Abstract

The flange bolts in-service inspection of reactor coolant pump in AP1000 Nuclear Power Plant is one of important supervision items. At present, there is no in-service inspection system and application case in China for this component. Combined with the structural characteristics of AP1000 reactor coolant pump flange bolts, the analysis of on-site high-dose environment and complex inspection conditions, this paper designs and develops a set of in-service ultrasonic inspection system for reactor coolant pump flange bolts, which implements ultrasonic inspection from the inner wall of the bolt center hole and is suitable for in-service inspection requirements. The debugging and test results on the simulation body of the reactor coolant pump show that the system can realize the functions of circumferential operation, vertical obstacle avoidance, precise alignment adjustment between the special ultrasonic probe and the bolt hole, etc., and then realize the ultrasonic scanning of the reactor coolant pump flange bolts. The engineering application results show that the system meets the requirements of in-service inspection of flange bolts of reactor coolant pump in AP1000 Nuclear Power Plant, and has high reliability and good applicability.
