Nuclear waste sealing container preparation system

Abstract

The nuclear waste sealing container manufacturing system comprises a shot blasting decontamination device, a metal smelting feeding assembly and a sand mold. The shot blasting decontamination device, the metal smelting feeding assembly and the sand mold are sequentially used in the preparation process of the nuclear waste sealing container. The shot blasting decontamination device comprises a spray gun, a sand and dust separator, a sand and dust collector, a steel ball cleaning machine, a steel ball 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. The nuclear waste metal serves as the raw material, the radiation dose in the nuclear waste metal is greatly reduced through the two steps of shot blasting and smelting, then all assemblies of the nuclear waste sealing container are cast through a sand mold, and finally the nuclear waste sealing container is formed through welding and assembling. By means of the process, recycling of the nuclear waste metal is achieved, and the requirement for minimizing radioactive waste can be fully met.

Description

technical field [0001] The invention relates to the technical field of nuclear waste metal treatment, in particular to a nuclear waste sealing container preparation system. Background technique [0002] With the rapid development of the nuclear industry, more and more nuclear wastes are produced by nuclear power plants and nuclear industrial enterprises, which are mainly produced by the decommissioning of old equipment that has reached the end of its useful life. These nuclear wastes are highly radioactive and have a half-life of thousands, tens of thousands or even hundreds of thousands of years. If they are disposed of indiscriminately, they will seriously pollute the environment and endanger human health. [0003] The International Atomic Energy Agency has strict requirements on the treatment and disposal of nuclear waste. For nuclear waste metals whose radiation dose exceeds the safety threshold, they cannot be disposed of. They can only be disposed of in permanent deep ...
