Abstract: A final depository located underground for storing radioactive wastes contained in storable shielded containers, composed of at least one shaft extending downwardly from the ground surface, an underground passage, a radioactive waste storage region located above the underground passage, and a connecting passage connecting the storage region with the shaft or the underground passage.

Abstract: A storage arrangement for radioactive waste includes a storage bore hole defined by walls of a rock formation, vessels containing radioactive waste deposited in a vertical series in the storage bore hole and a sealing closure situated in the storage bore hole above the uppermost vessel. The sealing closure is a prefabricated solid body (or several such bodies in a vertical series) closely conforming, along its circumference, to the shaft walls.

Abstract: Radioactive wastes are encased in closed sheaths, the wastes to be solidified with binders and accommodated in barrels and the closed sheath to be resistant to water and aqueous solutions of natural mineral salts and to leaching, by completely surrounding the waste by a synthetic resin layer between the waste and the barrel or around the barrel containing the waste in accordance with specific methods involving applying spacing layers in the areas to be occupied by the resin layer and subsequently filling the spacing layer with a synthetic resin and a solvent.
