Abstract

The invention relates to the field of radioactive waste treatment. A method for immobilizing tritium-containing liquid radioactive waste contaminated with radioactive salts and organic matter consists in solidifying said waste in a salt crystal matrix which is then immobilized in a durable mineral matrix. The waste is solidified by hydration of a slightly soluble crystalline phosphate hydrate by adding a pre-dehydrated slightly soluble crystalline phosphate hydrate to a container containing waste, and stirring until new crystalline hydrates are formed. The space remaining to an upper sealing cover of the container is filled with a durable mineral composition. A device is also provided for immobilizing tritium-containing liquid radioactive waste contaminated with radioactive salts and organic matter. The invention makes it possible to minimize radioactive contamination of materials and equipment.
