The method of disposal of nuclear substances


(57) Abstract:

The method of disposal of nuclear substances allows for the disposal of radioactive substances in any state: liquid, solid, and with the possibility of changing States of matter. Capacity for disposal is multi-layered and all is filled with an aqueous medium, each layer has a thickness that ensure compliance with radiation safety standards. Multilayer container of the nuclear substance is placed on the bottom of the reservoir. Each cavity is connected to the upper part of the back-pressure valve with external water environment. The inner cavity is additionally connected with the external environment by a tube placed in the lower part of the cavity. Tube bend up and fill with a liquid separating medium, which can be used mercury. The technical result is to protect the environment from radiation and contamination radioactive substance. 1 C.p. f-crystals, 1 Il.

The technical solution relates to the field of disposal of radioactive substances in liquid or solid state after use of the substance in the industry for any type of radiation or combination of types of radiation.

There is a method of placement of the radiation is postimage radiation (I, p. 141).

The disadvantages of the described method can be considered:

- you can activate the neutron flux of sediment in the aquatic environment, with consequent impacts on living creatures in the aquatic environment with all the consequences that

if the radioactive substance is in a liquid state, the entire volume will be dangerous to all living things with any type of radiation,

if the disposal is subject to the Assembly with neutron radiation, it is accompanied by emission in the form of helium, hydrogen, and sealed the signing of the substance in the tank would burst capacity with the emission of substances into the environment.

The situation is exacerbated by heat allocation substance with insufficient heat.

The combination of radiation, heat, gas leads to the destruction of almost any material, and the half-life can reach tens of thousands of years for heavy elements (II, page 141). Similar disadvantages does any reactor (research or energy), because all the factors mentioned above are present in the implementation process. All materials used in the reactor will break from these influences to which prilocaine deficiencies namely:

- ensure the protection of radioactive substances protective layer and a material that will provide for a specified period of the external security environment from radiation and direct exposure to substances in the environment,

- possibility of filling the storage of liquid, solid and material that can change its state, for example, when the destruction of the Assembly.

This objective is achieved in that the internal cavity of the container filled with radioactive material and communicate it with the external environment substance in liquid form through a tube, the capacity to perform multilayer and the entire volume, including the internal fill fluid, which will be omitted capacity, while the thickness of each water layer is carried out sufficient to ensure radiation safety standards each layer, each cavity is provided in its upper portion with a check valve direction in the environment.

Explanation way:

1. If should be buried Assembly in the solid state, it is located in the inner cavity with clearance relative to the first shell with a gap, which will provide security standard after the first shell. The retention Assembly may be carried out will limit KJV the NCI with a radioactive substance. It may be stand on legs, like a stool.

2. A more complex case, when the substance is in a liquid state and in this case there is a direct effect of radiation on the material wall. In any material, the wall will crumble. However, when the destruction of the first inner wall hundreds of times will decrease the concentration of radioactive substances, because the thickness of one layer between the inner and second wall must meet safety standards, but in the General case, the mass of water between the layers is subject cubic dependence (as for the ball in the General case), so the mass of one environment will increase not less than the 33= 27, since the thickness of the layer in the inner cavity will provide security. The second layer will reduce the concentration of the 27320,000 times. If layers of such a few, we can achieve an arbitrarily low concentration. Anyway, no one bothers to achieve any degree of protection as the destruction of the walls.

3. Materials for walls it is better to be combined: for example polyethylene and non-ferrous metal. Polyethylene keeps well the impact of sea water, as the metal color. The polyethylene can be sprayed. All construction is soft and can be thin-walled.

4. About the e tube with mercury, which will fill the lower part of the water environment in the inner cavity. Mercury will protect from radiation the lower part, and the resulting amalgam will make the bottom strong and protected. Mercury fill until liquid state of matter) until after the check valve on the upper part of the inner cavity will not receive the substance. This means that the internal cavity has an air environment. However, if the air will be formed in the process of radiation, it will be released through the check valve.

The surface of the mercury will be in contact with spring water environment and the internal environment of radioactive substances. Can change only the outer layer of mercury (to oxidize, for example, because the liquid cannot be destroyed, can be formed film). Diffusion is excluded due to the large difference in density and film forming.

Perhaps you can find a more efficient material instead of mercury, but it will require special searches.

Each cavity is filled with an aqueous medium, which is used for dipping, and all layers have the check valve with output up to possible leakage of gas or pressure relief temperature. Thus, the bottom soil will have Acoe device, because it is filled with an aqueous medium, which is the number of layers of water between the shells exceed the desired degree of protection. The device must not be laid on its side, it is desirable to have a large stand under it.

The design provides good heat, so thermal processes will not affect the integrity of the system. After a few hundred years, the entire design will be muddy and further its existence will be provided in a natural way. Mercury will go in the complete destruction in the ground, Yes it is small, because the hydraulic lock of the mercury does not require a large diameter.

Thus, we receive all of the above goals.

FIELD: physics; construction.

SUBSTANCE: process of crashed atomic reactor entombment includes construction of underground mortuary in the form of vertical underground excavation. Internal volume of the excavation is filled with ice which forms a new temporary ice foundation under the basis of the crashed reactor. The weight of the latter is shifted to the new ice foundation, heat is conducted to it, and gradually the height of ice foundation is decreasing till the complete removal of ice. At that, the crashed reactor is set at the mortuary made previously at the basement of excavation. Before deposition of the crashed reactor underground, solidity (thickness) of frozen soil body under the reactor basis is improved, and then, after the new ice foundation is ready, the load is increased, and the previous ground base is destroyed by adjoining of excavation ice body to the crashed reactor basis via flexible load-bearing cables laid through the vertical wells.

FIELD: construction, hydrotechnics.

SUBSTANCE: invention is attributed to cleaning methods for beds of minor rivers in permafrost zone with seasonal flow from sediments contaminated with radionuclides from radioactive solid waste handling. Removal of contaminated sediments is executed in winter by segments in downstream direction after discharge cancellation and their dewatering. Bottom ground is loosened and mechanically shaved by layers as it is freezed by natural cold with stocking it in temporary piles and subsequent transportation outside river floodplain for burying or laying in surface burial hills. To speed-up layer-by-layer freezing the net of trenches with vertical walls is cut in parallel in bottom ground depth as it freezes. Trench width is defined by parameters of equipment being used, their depth is not less than half a meter and distance between trenches corresponds to double trench depth. The invention allows to isolate from biota (for a period of not less than 100 years) the most migration suspectable solid radioactive wastes and hence to lower the risk of people irradiation.
