Abstract: With the aid of the process and equipment according to the invention, the transportation and storage of radioactive and/or other dangerous materials are realizable in accordance with the domestic and international regulations. The physical and radiation protection of the objects to be transported or stored are ensured by the dry, granular material (e.g. sand) filled into the equipment. Loading and removal of the objects are facilitated with fluidization of the granular material. The equipment includes gas distribution system, filter supported by lumpy material pressed between the grids, through which gas (e.g. air) is blown, whereby the granular material is fluidized. The object(s) is (are) positioned by a basket of lattice construction, its fastening dependent on the embodiment. The equipment has fixable cover, withdrawable dustproof cover, ribs for improving the cooling and for partical absorption of the forces arising at impacts.

Abstract: Liquid radioactive wastes are concentrated to form a pasty radioactive concentrate by evaporation below the boiling point of the waste by injecting a hot gaseous medium tangentially in a vortex stream over the entire surface of the liquid waste, thereby entraining vapor evaporated from the liquid surface, removing the gaseous medium together with the entrained vapor, drying and reheating the removed gaseous medium and recirculating it in a vortex stream over the surface of the waste, which may then be stored in the same container in which the evaporation took place.
