A method of treating radionuclid-containing metal waste includes melting of waste in the air environment with addition of refining fusing agents at a liquidus temperature below the metal waste melting point, slag induction and removal, and metal casting. In the newly-developed technology, technological slag produced in the process of calcium-thermal reduction of uranium tetrafluoride with oxide to calcium fluoride mol. ratio of (20-80%) to (80-20%), is used as a refining fusing agent. In the second modification of the method, a melting is blown up with an air or inert gas.
