Definitions
- the invention relates to the field of nuclear technology, in particular to devices for protecting the environment from environmentally hazardous materials, and can be used for storage, transportation and disposal of especially toxic waste, such as radioactive waste from nuclear power plants, nuclear vessels of the marine fleet, toxic materials of chemical industries and other hazardous industrial waste.
- the disadvantage of the known container is the unsatisfactory reliability of waste disposal associated with insufficient corrosion resistance of this container.
- the disadvantage of this container is unsatisfactory strength characteristics due to the brittleness of the silicon carbide layer, which reduces its operational reliability during technological operations associated with loading waste, moving the container during its transportation and loading into a transport container made of concrete or cast iron.
- the closest to the claimed invention in terms of the technical essence and the achieved result is a container for solid radioactive waste containing a canister made of reaction sintered silicon carbide containing free silicon in an amount of 3-30 wt%, on the surface of which a layer of gas-phase silicon carbide is applied (Patent RU . Nb2140402, G21F 5/005, 1998).
- the disadvantage of the known container for storage, transportation and disposal of solid radioactive waste is the low impact strength of the silicon carbide canister, which is further reduced, because radioactive waste is placed in a container by pouring vitrified waste into a silicon carbide case with a temperature of 1200 ° C. This leads to the appearance of thermal stresses in the canister, and after cooling of the vitrified waste - residual stresses, which reduces its operational reliability during technological operations: loading the waste, moving the container during its transportation and other manipulations.
- the container's disadvantage is the lack of means of protecting the environment from radiation emitted from radioactive waste.
- the purpose of this invention is to increase the strength of the container for solid radioactive waste and its reliability, as well as to protect the environment from radiation in AO.
- the outer layer of the case made of reaction sintered silicon carbide, containing free silicon in an amount of 3-30% of the mass, on the surface of which a layer of gas-phase silicon carbide is applied is made of foam metal (foam aluminum, foam titanium, foam copper, etc.) the case of foam aluminum with a porosity of 60-70%, a pore size of 5-6 mm, in pores Powder B 4 With a dispersion of 40-50 microns is filled in, which protects the environment from radiation emitted from HLW.
- the outer layer of the container is made of foam metal with an open porosity of 50-60 %, pore size 5-6 mm, the pores are filled with boron carbide powder with a dispersion of 40-50 microns, which protects the environment from radiation emitted from HLW.
- vitrified molten high-level waste is poured into a steel canister placed in a silicon carbide canister with a 5 mm gap between the canister and the canister wall. which is filled with boron carbide powder with a dispersion of 100-150 microns.
- the parameters of the outer layer depend on the size of the canister and its weight. The determination of these parameters was carried out by mathematical methods, all calculations were performed in the ANSIS program. As the initial data, the weight of the container was 170 kg, the strength of the material of the case was 270 MPa, the stresses in the case when dropped from a height of 1.2 m should not exceed 20-25 MPa. Under these conditions, the results calculations are as follows: the thickness of a layer of foam aluminum with a porosity of 60-
- pore size 5-6 mm is 110 mm.
- Pencil case made of reaction-sintered silicon carbide is manufactured according to the following technology.
- a layer of silicon carbide is applied to the outer surface of the case by the gas-phase method.
- foam metal with a thickness of 110 mm (foam aluminum, foam titanium, foam copper, etc.) is placed, on top of the foam metal a shell of steel with a thickness of 1.5 mm is placed.
- the pores of the foam metal are filled with powder B C with a fineness of 40-50 microns (see Fig. 1).
- the container made in accordance with the prototype, collapsed when falling on a steel plate from a height of 1.2 m, because the level of stresses arising from impact exceeds the strength of silicon carbide, which is 250 MPa.
- the silicon carbide case with a simulator of a can with HLW retained its integrity and tightness.
- the proposed container for storage, transportation and disposal of radioactive waste in comparison with the known container (Patent RU V "2140402, G21F 5/005, 1998) provides increased strength and reliability for storage and disposal of radioactive waste, as well as protection of the environment from radioactive radiation.
- Figure 1 shows a drawing of a container for storage, transportation and disposal of highly toxic waste, such as radioactive waste from nuclear power plants, nuclear vessels of the marine fleet, toxic materials from chemical industries and other hazardous industrial waste.
- the container includes (Fig. 1):
