Abstract

The invention discloses an automatic conveyer of nuclear fuel microsphere granules and an automatic detection platform. The automatic conveyer comprises a funnel, wherein an outlet end of the funnel is connected with a multi-segment circular tube, wherein the multi-segment circular tube comprises a first circular tube, a second circular tube and a third circular tube which are sequentially connected end to end; the first circular tube and the second circular tube are V-shaped; the third circular tube is vertically arranged downwards; the connected end of the first circular tube and the second circular tube is provided with an air pump for pushing the nuclear fuel microsphere granules into the third circular tube from the second circular tube; and an outlet end of the third circular tube is located at the upper end of an automatic detection device for detecting the quantity of the nuclear fuel microsphere granules. The invention further discloses a detection platform with the automatic conveyer. The overall dimensions and the sphericity of the nuclear fuel microsphere granules can be automatically detected, so that the detection efficiency can be improved, the detection time is shortened, the labor intensity of labor personnel is greatly reduced, the possibility of contacting a radioactive hazard is reduced and the detection platform is suitable for batch detection.

Description

technical field [0001] The invention relates to the technical field of detection equipment for nuclear reactor fuel elements, in particular to an automatic transmission device and an automatic detection platform for nuclear fuel microsphere particles. Background technique [0002] Nuclear fuel microspheres are the main components of micro-sealed fuel pellets in accident-resistant nuclear fuel elements (ATF) and high-temperature gas-cooled nuclear reactor (HTGR) fuel elements. The size and sphericity of nuclear fuel microspheres are the key indicators for its quality inspection. However, nuclear fuel microsphere particles are generally radioactive, and the surface has radioactive contamination during the manufacturing process. In the actual production inspection, manually inspecting tens of thousands of microsphere particles in a furnace is not only a heavy workload, but also long-term radioactivity is not conducive to labor protection of personnel. [0003] Based on this, ...
