Abstract

The application provides a matrix powder coating equipment and process method for spherical nuclear fuel particles, including a coating host, a matrix powder supply mechanism, a wetting agent delivery mechanism, an exhaust and dust removal mechanism, and a hot air mechanism; wherein the coating The host machine includes a dressing pot, a drive mechanism and a frame that are in transmission connection with the dressing pot, and the pot body of the dressing pot is rotatably mounted on the frame around a horizontal axis driven by the drive mechanism; The pot body has a non-porous structure; the output end of the matrix powder supply mechanism, the output end of the wetting agent delivery mechanism, the output end of the exhaust and dust removal mechanism, and the output end of the hot air mechanism all penetrate into the Describe the pot body of the dressing pot. The matrix powder coating equipment and process method for spherical nuclear fuel particles provided by the invention solves the technical problem that the equipment in the prior art cannot meet the demand for capacity expansion.

Description

technical field [0001] The present application relates to the technical field of nuclear fuel processing equipment, in particular to a matrix powder coating equipment for spherical nuclear fuel particles in the manufacture of nuclear fuel elements. Background technique [0002] With the development of nuclear energy technology, coated nuclear fuel particles are widely favored for their outstanding safety characteristics. In addition to being used in high-temperature gas-cooled reactors and molten salt reactor fuel elements, they may also be used in pressurized water reactors, space reactors, fast Stacks and other stacks, the fuel components of these stacks are spherical, columnar or plate-shaped, the matrix includes ceramics, metals, carbon and other materials, and most of the molding processes are press molding. Due to the high pressure during the pressing process, in order to avoid the direct contact between the fuel particles and the pressure rupture, it is necessary to c...
