The invention discloses a nuclear material plate cladding thickness detection device which comprises a feeding roller way conveying device (1), a support (2) and a discharging roller way conveying device (3) which are sequentially arranged from left to right, a calibration assembly (4) and a detection assembly (5) are arranged at the front end and the rear end of the support (2) respectively, and the calibration assembly (4) comprises a driving motor (6) and two vertical plates (7) which are oppositely arranged left and right. The two vertical plates (7) are fixedly arranged on the top surface of the support (2) and arranged on the front side of the feeding roller way conveying device (1), the driving motor (6) is vertically arranged and arranged on the front sides of the vertical plates (7), a rotating disc (8) is installed on an output shaft of the driving motor (6), and a plurality of standard zirconium piece clamping mechanisms (9) are arranged on the edge of the rotating disc (8) in the circumferential direction of the rotating disc (8). The zirconium sheet thickness detection device has the advantages of being compact in structure, improving zirconium sheet thickness detection efficiency, reducing detection cost and being easy to operate.
Description
technical field [0001] The invention relates to the technical field of thickness detection of zirconium sheets on a nuclear fuel plate, in particular to a device for detecting the thickness of a cladding of a nuclear fuel plate. Background technique [0002] The nuclear fuel plate is of long strip type and consists of a fuel layer in the middle and a zirconium cladding layer above and below. The thickness of the zirconium cladding is directly related to the safety of the nuclear fuel plate, so the detection of the thickness of the zirconium cladding in the production process is particularly important. Due to the special processing technology, the interface between the zirconium cladding layer and the core is not clear, and traditional methods such as ultrasonic thickness measurement and eddy current thickness measurement cannot accurately detect the cladding thickness. The existing mature technology is to use the beta ray released by the decay of the core itself to transmit...
