Abstract

The special steel shot preparation system is used for removing radioactivity of the nuclear scrap metal and is used for preparing steel shots; the device comprises a shot blasting decontamination device, a metal smelting feeding assembly and a shot making equipment assembly, the shot blasting decontamination device, the metal smelting feeding assembly and the shot making equipment assembly are sequentially used in the steel shot preparation process. The shot blasting decontamination device comprises a spray gun, a sand and dust separator, a sand and dust collector, a steel shot cleaning machine, a steel shot repriatrix, a dry ice supply device, a high-pressure air source and a negative-pressure exhaust device. The metal smelting feeding assembly comprises a main frame, a vertical elevator, a smelting furnace assembly, a trolley assembly, a feeding butt joint mechanism, a negative pressure dust removal mechanism and a material conveying mechanism. According to the method, the nuclear waste metal serves as the raw material, the steel shot special for metal core decontamination is prepared, radioactive waste is not additionally generated in the steel shot preparation process, multiple times of cyclic utilization can be achieved through the cleaning process in the steel shot using process, and the requirement of radioactive waste minimization is fully met.

Description

technical field [0001] The invention relates to the technical field of decontamination of metal nuclei, in particular to a special steel shot preparation system for removing the radioactivity of nuclear waste metals. Background technique [0002] With the rapid development of the nuclear industry, nuclear waste metals produced by nuclear power plants and nuclear industrial enterprises are also showing a trend of increasing year by year. Nuclear waste metals can be divided into high, medium, and low levels according to their radioactivity. Among them, high- and medium-radioactive nuclear waste metals are usually difficult to use and can only be buried. However, the places for landfills are very limited and difficult to find. . [0003] If radioactive decontamination and degradation of nuclear waste metal can be carried out (that is, the relatively high radioactive surface metal of nuclear waste metal is stripped, and only the relatively low radioactive inner metal is retaine...
