description The invention relates to a CEPR nuclear power plant control rod driving mechanism weld ultrasonic scanner positioning device. The device comprises a housing sleeved on the control rod, and at least one circumferential positioning assembly arranged on the housing. An ultrasonic scanning probe of the scanner is arranged in the housing. The circumferential positioning assembly comprises swing racks rotatably arranged on the housing, pressing parts arranged on the swing racks, and flexible adjustment cords connected to the swing racks or the pressing parts. The circumferential positioning assembly has two working states. In a first working state, the swing racks and the pressing parts are close to the housing, such that the positioning device is mounted on the control rod to be detected. In a second working position, the swing racks and the pressing parts are expanded relative to the housing, and the pressing parts are pressed against control rods adjacent to the control rod to be detected. With the positioning device, circumferential precise positioning can be realized, and positioning precision is high.
