Abstract : A concretized coating which encapsulates canisters of radioactive, heat-producing materials is caused to be formed by immersing said canister in a sea floor sedimentary layer, the sediment containing feldspathic material. The canister heats the surrounding water causing alkali and alkaline materials to be leached from the seabed sediment. An indurated concretized layer of anhydrite and sedimentary particles is then formed by precipitation of anhydrite and other agents from the hot pore water, that is, water in the proximate environment of the canister. This concretized barrier provides protection to the fuel capsule against intrusion by the corrosive seawater. Keywords: Radioactive wastes; Ocean bottom soils; Ocean waste disposal; Deep Oceans; Patents.
