Abstract
An underground repository for the storage of radioactive material, particularly spent fuel from nuclear reactors and radioactive wastes produced by reprocessing spent nuclear fuel. The repository comprises a hollow body of solid material for accommodating the radioactive material. The hollow body is surrounded by a shell or barrier of clay. The hollow body and the clay barrier are located in a cavity in rock, the clay filling the space between the hollow body and the inside of the rock cavity.
Claims17
An underground repository for the storage of radioactive material and other materials in a rock formation, comprising a first cavity in said rock formation, a first body of rock derived from said rock formation by having been left at the excavation of said first cavity so as to be located within said first cavity and spaced on all sides from the walls of said first cavity, the space between said first body of rock and the walls of said first cavity being filled with a plastically deformable material supporting said first body of rock in said spaced relationship relative the walls of said first cavity, said first body of rock being hollow and containing in its interior storage space for the material to be stored, and shaft means extending through said rock formation, said space filled with said plastically deformable material and said first body of rock to said storage space for the transfer of the material to be stored into said storage space.
