Description

Technical Field

[0001] The invention relates to the technical field of radioactive waste pre-compression, in particular to a retractable barrel sleeve protection system based on radioactive waste pre-compression. Background Art

[0002] In recent years, many nuclear power plants have gradually entered the decommissioning stage. The dismantling of these facilities will generate a large amount of low- and medium-level radioactive wastes, which must be collected, transported and stored. Faced with this challenge, the industry urgently needs waste reduction solutions to minimize the volume of radioactive wastes, because these wastes need to be stored safely for a long time. Pre-compression of radioactive waste is a typical case. The pre-compression process is a standard process in the nuclear industry, which aims to reduce the volume of pre-compressible wastes at the waste generation site. Pre-compressible wastes usually include lightweight wastes such as rags, clothing, plastics and light metal profiles. These wastes are The waste can be greatly compressed under a pressure of about 10 tons. The process is carried out in 220-liter (50-gallon) barrels. The waste is manually loaded into the barrels placed in a closed cabin to prevent the spread of contamination. Then the pressure head is used to compress directly in the barrel. The process is repeated until the barrel is full. The main limitation of the process is that the barrel itself is not strong enough and usually cannot withstand compression pressure exceeding 10 tons. This limitation hinders the ability to further reduce the volume of waste. Although at a pressure of 50 tons, the effect of waste volume reduction is almost linearly related to the compression pressure, so the potential of the process has not been fully realized.

[0003] The traditional method of keeping waste barrels has the following disadvantages:

[0004] (1) In order to maintain the integrity of the waste barrels as much as possible, the following methods have been used: Manual waste loading: The operator must manually load the waste carefully throughout the process, which not only increases the complexity of the work, but also forces the operator to be exposed to the radiation environment for a long time, directly operate and slowly handle the waste, increasing the risk of radiation exposure;

[0005] (2) Reduce the compression force: To avoid damaging the barrel, the compression force is usually limited to 10 tons;

[0006] (3) Reduce the amount of waste barrels filled: Since the last few bags of waste tend to overflow from the barrel when compressed, causing the upper edge of the barrel to be crushed, it is often necessary to reduce the total amount of waste barrels filled;

[0007] (4) Reduce the amount of waste in each bag: This is done to reduce the friction between the waste and the barrel during the compression process, avoiding the barrel curling or barrel mouth curling deformation caused by friction;

[0008] (5) Avoid loading waste with hard, metal or sharp edges: Such waste may puncture or tear the barrel. All of these methods of protecting waste barrels have a negative impact on operator safety, the efficiency of the volume reduction process, and the filling degree of the waste barrel.

[0038] When the embodiment of the present application is in use: the design of the sleeve 10 includes a cylindrical sleeve made of structural stainless steel, the thickness of which is sufficient to support all the forces generated during the compression process. The height of the sleeve covers the entire compression chamber, the waste barrel and the feed chamber. Its outer diameter is smaller than the inner diameter of the 220L waste barrel, and the inner diameter matches the diameter of the compression head passing through the sleeve to effectively compact the waste.
