Abstract

The invention discloses a fuel plate surface pollution positioning and detecting device and system. The fuel plate surface pollution positioning and detecting device comprises a shielding cover, an upper surface detecting unit, a lower surface detecting unit, a lifting unit, a workpiece conveying unit and a supporting mechanism. The shielding cover is fixed on the supporting mechanism, and the shielding cover and the supporting mechanism form a cavity so as to accommodate the upper surface detecting unit, the lower surface detecting unit, the lifting unit and the workpiece conveying unit whichare arranged on the supporting mechanism. When fuel plate surface pollution detection is carried out, a fuel element is placed on the auxiliary supporting mechanism of the detection device, a detection equipment box body is closed, the workpiece conveying mechanism is started, the fuel element is conveyed to a detection initial position, and after the fuel element is in place, the detecting unitsare started for detection. The device is high in automation degree, large in detection area, low in failure rate and high in safety coefficient, can achieve accurate positioning and detecting of pollution points, facilitates cleaning of surface pollution, and avoids secondary pollution.

Description

technical field [0001] The invention relates to the technical field of nuclear detection, in particular to a device and system for locating and detecting contamination on the surface of a fuel plate. Background technique [0002] Fuel plates have been widely used due to their excellent properties. However, in the development process of the fuel plate, in order to ensure the manufacturing quality and prevent possible spread of nuclear pollution, it is necessary to detect the amount of uranium contamination on the surface of the nuclear fuel plate. Moreover, in order to confirm the location of the pollution point, facilitate cleaning and reduce the secondary transmission of pollution, it is particularly important to locate and detect the surface pollution point. Therefore, it is of great significance to complete the detection and location of fuel plate surface contamination for the development and production of fuel plates. [0003] At present, the detection of surface conta...
