FIELD: chemistry.
SUBSTANCE: electrochemical deactivation of the metal is carried out in the method with simultaneous exposure to ultrasonic vibrations. As a deactivating solution, an aqueous solution of an acid is used, the anion of which forms an insoluble compound with calcium. Then, the spent deactivating solution is neutralized. The solution separated from the suspension is then reinforced and reused. Liquid radioactive waste, which is a suspension of metal hydroxides and hardly soluble compounds formed by calcium and anion of the corresponding acid, is liquefied.
EFFECT: increasing the efficiency of decontamination.
