Definitions
- the invention relates to packaging kits intended for the transportation and transit storage of radioactive materials by all modes of transport, including air.
- transport packaging sets intended for the transportation and transit storage of radioactive materials must provide high radiation-protective and strength properties, including in case of emergencies that may occur during transportation and storage.
- radioactive material especially by air transport: in accordance with IAEA safety requirements N° SSR-6, packages for fissile materials intended for air transport must pass enhanced thermal tests, when the package is kept in a thermal environment for 60 minutes, and the test for collision with a target at a speed of at least 90 m/s.
- the container is not intended for transportation of nuclear hazardous materials
- the arrangement of the container does not ensure the radiation and nuclear safety of the transported materials.
- TUK for the transportation of spent nuclear fuel - fuel assemblies of a nuclear reactor by all modes of transport, including air (see patent RU 2581648, G21F5 / 00), - a prototype, which is a container consisting of an inner and outer casing, on which during transportation Removable shock absorbers are installed, fastened to the container with a bolted connection, while the dampers are made of titanium alloy and have a ribbed surface.
- TUK The disadvantages of this TUK include the restriction on the nomenclature of the transported fissile material, associated with the design of its containment system; low manufacturability of use, associated with the need to install / remove damping devices when loading / unloading the contents being transported.
- the technical problem to be solved by the invention is the creation of a TUK design that does not allow the opening of the container body, leading to leakage, dispersion of the transported fissile material, redistribution of material inside the package with loss of material spacing, thermal effects and ignition elements of TUK with a simultaneous increase in the manufacturability of the use of TUK.
- the technical result of creating such a design of the TUK is to meet the requirements of radiation and nuclear safety during the transportation and transit storage of nuclear fissile materials and to improve the performance of the TUK.
- the inner case of the container contains a cover with slots designed for installation of containers with uranium-containing fissile material, the free cavities of the cover are filled with material that performs the function of neutron protection, while the shock absorber is located on the outer surface of the outer power body of the container and is impregnated with a fire retardant composition, a wooden mass with an outer lining made of steel sheet, while a refractory material is laid between the damper and the lining.
- the problem is also solved by the fact that the case installed in the inner casing of the container can have five slots designed to install containers with uranium-containing fissile material. In each nest, it is possible to install two containers one above the other.
- boron carbide powder can be used as a material that performs the function of neutron shielding.
- MBOR fabric can be used as a refractory material used to cover a solid wood, which acts as a shock absorber.
- the proposed design of the transport packaging set allows to solve the set technical problem.
- the use of two hermetically sealed covers in the TUK design ensures compliance with the requirements of the IAEA rules to prevent the redistribution of radioactive contents inside the package.
- the use of refractory materials in the design of the TUK makes it possible to exclude the ignition of the shock absorber, ensuring the safety of the sealing gaskets during thermal effects on the package.
- FIG. 1 shows a TUK container for transporting uranium-containing fissile materials, general view.
- FIG. 2 shows the fastening of the cover of the outer body of the container (fragment).
- FIG. 3 shows the fastening of the cover of the inner body 20 of the container (detail).
- FIG. 4 shows a container for uranium-containing fissile material, placed in the nest of the cover of the inner body of the container.
- TUK includes a container that contains an external power housing 1, closed by a lid 2, and an inner housing 3, placed in a housing 1 and closed by a lid 4. Inside the housing 3 there is a cover 5 with nests that serve to accommodate containers 6 for transported uranium-containing fissile material.
- the outer casing 1 is made in the form of a steel cup, on the outer surface of which a shock absorber 7 is installed, made, for example, of solid wood impregnated with a flame retardant composition and lined on the outside with a sheet 8 of sheet steel. Between shock absorber 7 and sheet 8 steel placed refractory material 9, for example, fabric MBOR, designed to protect shock absorber 7 from temperature effects in emergency situations.
- a plug 10 On the side of the cover 2 of the body 1 is installed a plug 10 in the form of a disk made of damping material, for example, wood, coated with a flame retardant and lined with sheet steel.
- the cover 2 of the outer casing 1, made of thick sheet material, is attached to the casing 1 using reinforced bolts 11.
- a sealing gasket 12 is installed between the casing 1 and the cover 2, which serves to prevent the loss of the transported contents both in normal and emergency situations.
- the plug 10 is attached to the outer body 1 with the help of nuts 13.
- a sealing gasket is installed between the plug 10 and the body 1, which prevents atmospheric precipitation from entering the body 1 (not shown).
- lugs 14 are fixed by welding, designed to lift, move the TUK, and also to secure it with the help of couplers in the vehicle.
- supports 15 are welded to the surface of the body 1 in the upper part, intended for tiered storage of TUK, and four supports 16 in the lower part.
- the cover 4 made of thick-walled material, is attached to the inner body 3, made in the form of a glass of thick-walled material, using reinforced bolts 17.
- a sealing gasket 18 is installed between the body 3 and the cover 4, which serves to prevent the loss of the transported radioactive contents, as in normal, as well as in emergency situations.
- special lugs 19 are welded, which serve to install/remove the body 3 of the container into the power outer case 1.
- a cover 5 in the form of a drum, for example, with several slots for accommodating containers 6 with transported contents.
- the free cavities of the cover 5 are filled with a neutron-absorbing material 20, for example, boron carbide powder B 4 C.
- the container 6 is a cylindrical body 21 with a lid 22 connected by a thread.
- TUK is carried out as follows.
- Uranium-containing fissile material for example, in the form of powder, crumbs, tablets, metal ingots, is packed in a polyethylene case, which is placed inside the body 21 of the container 6 and closed with a screw cap 22.
- the containers 6 with the material packed in them are placed in the sockets of the case 5 installed in the inner cavities of the body 3 of the container.
- the body 3 is closed with a cover 4, which is attached to the body with the help of bolts 17 of a reinforced structure.
- the filled and closed housing 3 is installed in the power outer housing 1 with the cover 4 down.
- the cover 2 of the outer casing 1 is installed and fastened with bolts 11 of a reinforced structure.
- plug 10 is installed and fastened with nuts 13. After that, contamination of the outer surface of the TUK is carried out in accordance with the requirements of the IAEA rules.
- TUK of the proposed design has passed type tests. The declared strength properties are confirmed. The possibility of expanding the range of transported radioactive contents is provided.
- the use of the TUK of the proposed design for the transportation of uranium-containing fissile materials is guaranteed to ensure the radiation and nuclear safety of the transported materials by any mode of transport, including air, while the use of the TUK of the proposed design is less costly and more technologically advanced compared to existing samples.
