uo2 pellet perpendicularity detection system and detection method

Abstract

The invention discloses a UO2 pellet perpendicularity detection system and a detection method thereof. The UO2 pellet perpendicularity detection system comprises an upper computer and a detection device, wherein the detection device comprises a base, a guide rail is arranged on the base, a sliding table is arranged on the guide rail, a stepping motor is installed on one end of the guide rail, and a pellet positioning device is arranged on the side surface of the sliding table; line type laser scanners are arranged on both sides of the guide rail; and the upper computer is connected with the stepping motor and the two line type laser scanners. The detection method of the UO2 pellet perpendicularity detection system comprises the steps of: 1) placing a UO2 pellet to be detected on the pellet positioning device; 2) conducting scanning detection on the end surfaces of the UO2 pellet to be detected synchronously by means of the two line type laser scanners; 3) and carrying out data processing by the upper computer via a data processing system, so as to obtain perpendicularity of the UO2 pellet. The UO2 pellet perpendicularity detection system and the detection method thereof can be used for detecting the UO2 pellet quickly, and can detect a plurality of the UO2 pellets simultaneously, thereby significantly improving the detection efficiency of the UO2 pellets.

Description

technical field [0001] The invention relates to the technical field of product detection, in particular to a UO with a columnar structure 2 A detection system and a detection method for the perpendicularity between the end face of a core block and the axis line. Background technique [0002] During the production and processing of nuclear fuel, UO 2 The gap between the (fuel) pellet and the cladding tube is an important factor affecting the temperature of the nuclear fuel pellet. Since the fuel pellet is cylindrical as a whole, and its two ends have grooves so that the two ends are ring-shaped, the perpendicularity between the end surface of the fuel pellet and the axis directly affects the accuracy of the gap measurement between the nuclear fuel pellet and the cladding tube degrees, therefore, at UO 2 During the production process of the pellets, it is particularly important to test the verticality accuracy of the pellets. [0003] The traditional detection methods main...
