    The invention relates to the storage and transportation of radioactive and other hazardous substances. The purpose of the invention is to increase the safety of transportation and storage. The essence of the method lies in the fact that during loading and unloading the granular material is fluidized and in this state the objects are placed in the container or removed from it. For this purpose, a distributor and sprinkler heads are installed at the bottom of the tank, and a box is placed on the springs in the tank itself. To delay the granular material in the bottom of the tank there is a filter installed between the grids on the supporting flanges. 2 sec. f-ly, I zp f-ly. 2 Il. yuso sp

     The invention relates to methods and devices for transporting and storing items with radioactive and / or other hazardous substances. The purpose of the invention is to increase integrated safety during storage and transportation of items with radioactive and / or other hazardous substances. Work according to this method is performed as follows. An object with radioactive and / or other hazardous substances is loaded into a container filled with granular material. During loading, the granular material is transferred to a pseudo-liquid state by blowing gas, such as air, into days (e capacity through the filter. When gas is blown at a speed sufficient to maintain the granular material in suspension, the friction between the grains decreases and the granular the material comes to a pseudo-liquid state. In this case, loading and moving an object with radioactive and / or other dangerous substances does not cause difficulties and becomes similar to loading and moving objects in a liquid, for example After the object is installed in the tank, the gas is stopped and the granular material under the action of gravity is deposited and compacted in the container around the object, providing protection and safety. The container is installed in the storage or transported to the desired place of delivery. radioactive and / or other hazardous substances from the container after storage or transportation in the same way transfer the granular material into a pseudo-liquid state and remove the item from the container and. FIG. 1 shows one of the possible embodiments of a transport device for carrying out the proposed method, a slit; in fig. 2 — another embodiment of the device more adapted for the storage of items with radioactive and / or other hazardous substances (storage option). The device contains its capacitance 1, which is located on the top, is closed with a seal of the hinge 2. Capacity 1 and crinkle 2 are externally provided with stiffening ribs 3, which increase the shock resistance of the tank and improve air cooling. A support flange 4 is installed in the bottom of the tank, into which a filter 5 is built with a seal, made of dense felt or other flexible screening material with high air resistance (desired resistance with air passing is 0.1-1 kPa at an air speed of 3cm / s) . The filter 5 is fixed below and above by a grill 6, which prevents the latter from deforming when blowing air. Under the filter 5 there is a layer 7 of coarse lumpy material (for example, a gravel), which has a uniform air distribution. Read 1: The size of the piece from Lo 7 is 3-5 mm. Subject 8 with radioactive and / or other hazardous substances is placed in a container 1, while on all sides it is surrounded by a granular material 9, for example sand. Under the filter 5 in the layer 7, the gas distributor 10 is placed and sprayed above the head 11. In order to prevent the object 8 from moving with the radioactive and / or other 3d hazardous substances during transportation and fixia in the container dent, the object 8 is placed in a grid box 12 closed with a grid cover 13, Lattice the box 12 is elastically attached to the internal ribs 14 of the capacity of the container I by means of springs 15 protected by rubber caps. To adjust the level of the granular material 9, a notch 16 is provided in the upper part of the container 1, which the excess granular material 9o can change; The container is mounted on the stand 17, which is attached to the tank 1 by means of an apron 18. To lift the tank 1, there are three racks i 9, which are attached to the stand 17 and provided with lifting lugs 20 Dust bellows contains 21, preventing dispersion to the outside of the granular material 9 during blowing. The device works as follows. When the item (or objects) 8 with radioactive and / or other hazardous substances is loaded from the tank 1, the cover 2 is removed, the dust bellows 21 is pulled out, air is blown through the gas distributor 10 and the spraying heads 11 by means of an external compressor (not shown). In this case, the granular material 9 is transferred to a pseudo-liquid state. Then the lattice cover 13 of the lattice box 12 is opened and an object or objects 8 with radioactive and / or other dangerous substances are put in there, after which the lattice cover 13 is closed. Air supply from the compressor stops, sedimentation and compaction of granular material 9 occurs around object 8 in tank I. If necessary, the upper surface of granular material 9 is leveled, Dust bellows 21 is inserted into place and container 1 is closed by cap 2. After that, the lifting cable is fixed on the lifting lugs 20 and the container I is mounted with its support 17 on the vehicle platform and transported to the destination. The device is removed from the platform and installed in the desired location. If necessary, the removal of the object (s) 8 from the container 1 is performed in the same sequence as during loading.
    A possible design of a device for storing items with radioactive and / or other hazardous substances is shown in FIG. 2
    The main structural elements of the warehouse version are the same as in FIG. 1, structural elements can be simplified to ensure the proper position of the object and to transport the device. However, when storing objects of high activity, additional structural elements are required to ensure the intensity of cooling: two fittings 22 are located on the cap 2 to periodically purge the air space under the cap 2 to control the activity, for better heat transfer the number of stiffeners 3 increases.
    In addition, gas-conducting channels 24 should be provided at the bottom of the concrete charge 23 where the device is stored. Cooling air is supplied into the gap between the concrete charge and the storage container, which is blocked from above by a seal 25. The air is discharged through the exhaust channels 26 to the gas-collecting manifold 27.
     Work with the storage device option is performed in the same way as with the transport one.
