METHOD OF IMMOBILIZATION OF LIQUID RADIOACTIVE WASTES CONTAINING TRITIUM AND POLLUTED BY RADIOACTIVE SALTS AND ORGANICS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC G21F9/00 G21F9/16 

FIELD: recycling and disposal of waste.

SUBSTANCE: group of inventions refers to the field of liquid radioactive waste processing. Method of immobilization of tritium-containing liquid radioactive waste polluted by radioactive salts and organics consists in their curing in a salt crystalline matrix, which is then immobilized in a strong mineral matrix. Curing of the waste is carried out by hydration of a poorly soluble phosphate crystalline hydrate by dropping the previously dewatered slightly soluble phosphate crystal hydrate into a waste container and stirring to form new crystalline hydrates. Space to the upper hermetic cap of the container is filled with a strong mineral composition. There is also a device for immobilizing tritium-containing liquid radioactive waste contaminated with salts and organics.

EFFECT: group of inventions allows to ensure minimization of radioactive contamination of materials and equipment.
