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: Slurry to be densified by removal of water is passed into an inlet of a housing, through the housing, and out an outlet. Inside the housing are a plurality of elongated hollow filter elements, which extend in the direction of flow of the slurry. Water in the slurry passes through the walls of and into the interiors of the hollow filter elements, as the slurry flows along the lengths of the filter elements. The cross-sectional area of the flow space for the slurry, defined between the exterior surfaces of the filter elements and the interior wall of the housing, decreases as one proceeds along the lengths of the filter elements. As a result, the flow speed of the slurry does not decrease proceeding in the flow direction, but instead is maintained at least substantially constant, or is even caused to increase (accelerating flow).
