The nuclear waste sealing container preparation method is applied to the nuclear waste sealing container preparation system and used for preparing the nuclear waste sealing container. The nuclear waste sealing container manufacturing system comprises a shot blasting decontamination device, a metal cutting machine, a metal shredding machine, a metal compression packing machine, a metal smelting feeding assembly and a sealing container manufacturing assembly. The method for preparing the nuclear waste sealing container comprises the following steps: surface shot blasting; fragmentation processing is carried out; compressing and packaging; feeding in a cold furnace; smelting metal; and preparing a nuclear waste sealing container. 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. Based on 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 method for preparing a nuclear waste sealing container. 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 d...
