The essence of the invention: on a floating platform made of space prestressed concrete in tubular - cylindrical or toroidal containers. Then the platform with the container is transported to the location of waste, opposite lock and load waste, seal the container by seminolecounty closing element bend concrete. Platform containers are transported by surface waters, and then water canal connecting the waters of the store, arranged at the bottom of the channel, immerse the containers on the bottom of the vault, which is poured around the perimeter of the ground before the formation of inverted cone with a height equal to the height of the vault and base diameter not less than 0.25 the width of the store. 5 C.p. f-crystals.

The invention relates to the protection of the environment, and in particular to methods of purification of waters from radioactive and toxic waste, burial and reburial.

The known method zakhor is diversified coatings, the waste sealing container and its subsequent dive to the bottom of the waters /1/.

The disadvantages of this method are the difficulty of ensuring the tightness of the containers in their manufacture due to the presence of corners, as well as the need for transportation of containers with special vehicles to the place of burial and natural sinking them to the bottom of the water area that does not provide ecological safety of the environment and control of environmental conditions.

The closest is the method of burial and reburial of radioactive and toxic waste in the water area, including production volume prestressed concrete toroidal container on a floating platform, the transport platform with the container to the location of waste, fixed opposite the location of the waste load waste container, sealing the container by seminolecounty closing element bend concrete, transportation to the place of burial of the first surface area, and then by artificial water canal connecting the waters with located at a distance from the containers sunk well after extracting platforms, and at the disposal of each subsequent top-container produce deep buried well of the height of the floor of the store. When this channel is filled with water before transporting platform with top-container from the waters to groundwater storage and dry after removing the platform from under the tor of the container and return it to the water area /2/.

The disadvantages of this method are the complexity of construction of the artificial channel and the installation of standpipe well due to the large amount of excavation and complexity of design illustration: " well, the dependence of the method of transportation tor containers from the presence of tides and water levels in the waters.

The technical challenge is to simplify the method of disposal of radioactive and toxic waste in the water area in underground storage, by reducing excavation and use of natural resources.

The problem is solved in such a way that in the method of burial and reburial of radioactive and toxic waste in the water area, including production volume prestressed concrete tubular container floating on the location of waste the loading of the waste container, sealing the container by seminolecounty closing element bend concrete, transportation to the place of burial of the first surface area, and then along the water canal connecting the waters with located at a distance from the shore underground storage, disposal by successive immersion of the containers in the store, according to the invention, the storage arrange on the bottom of the channel, after immersion of the containers in the store first store near the channel block by placing a jumper, then store fall asleep on the perimeter of the ground before the formation of inverted cone with a height equal to the height of the vault and base diameter not less than 0.25 the width of the store, then formed a cone filled genomescan mixture, displacing water from the cone into the waters, and then, on the surface of the vault form a mound above ground level, with an additional arrange the jumper near the waters, and the channel is covered with soil. Moreover, the container is made in the form of a torus or cylinder. In addition, to monitor the state of the waste in the repository in the cavity formed by the container, establish vertical reinforced concrete chimney height above onogo fact, what store arrange on the bottom of the channel, after immersion of the containers in the store first store near the channel block by placing a jumper, then store fall asleep on the perimeter of the ground before the formation of inverted cone with a height equal to the height of the vault and base diameter not less than 0.25 the width of the store, then formed a cone filled genomescan mixture, displacing water from the cone into the waters, and then, on the surface of the vault form a mound above the level of the soil that allows the use of natural resources channel, the channel to accommodate the storage and isolation of the channel from the waters by hydraulic device jumpers and backfilling with soil and genomescan mixture, the latter provides additional biosecurity store. To ensure the reliability of protection additionally arrange the jumper near the waters, and the channel is covered with soil. Containers are made in the form of a torus or cylinder that provides a streamlined shape, buoyancy (the ability to smoothly immersed in water and to be in pdfsplit state after loading their waste). When filling the formed cone warehouse filled with water, genomescan mixture p is wow, to monitor the state of the waste in the repository in the cavity formed by the containers. establish vertical reinforced concrete chimney height above the level of the embankment. And form a mound of local materials or genomescan mixture.

The method is as follows.

First, on a separate floating platforms made of space prestressed concrete in tubular - cylindrical or toroidal containers. Then the platform with the container is transported to the location of waste, fix it opposed the location of waste and waste load. The sealing of the container is carried out by seminolecounty closing element bend concrete. Platform loaded with waste containers transported by surface waters, and then water canal connecting the waters of the store. Store arrange on the bottom of the channel, which is used as a natural ducts of sufficient dimensions and depth, using the natural bottom or specially constructed Foundation. Disposal of produced by sequential immersion of the containers on the bottom. When this platform from under the con is, in the result, the load is redistributed to the water frame. After immersion of the containers first store near the channel block by placing a jumper waterworks. Then store fall asleep on the perimeter of the ground before the formation of inverted cone with a height equal to the height of the vault and base diameter not less than 0.25 the width of the store. As the soil can be used by any local material: stones, sand, clay, etc. Then formed a cone filled genomescan mixture, displacing water from the cone into the waters. The load then takes genomescan frame. Then, on the surface of the vault form a mound above ground level from local material or genomescan mixture. After the device jumpers are installed in the internal cavity of the storage vertical reinforced concrete pipe in the form of precast or monolithic structures. To ensure the reliability of protection additionally arrange the jumper near the waters, and the channel is completely covered with soil.
