Abstract

The invention provides matrix powder coating equipment for spherical nuclear fuel particles and a technological method. The matrix powder coating equipment comprises a coating main machine, a matrix powder supply mechanism, a wetting agent conveying mechanism, an air exhaust and dust removal mechanism and a hot air mechanism, wherein the coating main machine comprises a dressing pot, a driving mechanism in transmission connection with the dressing pot and a rack, and a pot body of the dressing pot is rotatably mounted on the rack around a horizontal axis under the driving of the driving mechanism; the pot body is of a non-porous structure; and the output end of the matrix powder supply mechanism, the output end of the wetting agent conveying mechanism, the output end of the air exhaust and dust removal mechanism and the output end of the hot air mechanism all penetrate into the pot body of the dressing pot. According to the matrix powder coating equipment for the spherical nuclear fuel particles and the technological method, the technical problem that equipment in the prior art cannot meet the requirement for capacity expansion is solved.

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...
