Abstract: The invention is aimed to be used in nuclear power plants, nuclear industries and points of radioactive waste disposal. The treatment includes loading of the contaminated metallic waste and flux into the furnace, melting of metallic waste and removing of the melt and slag flux from the furnace. Before loading the waste and the flux into the furnace, layer of radioactively contaminated graphite is loaded and it is ignited in oxidizing medium, generated by the plasma of plasma torch furnace. Then, plasma torch is turned off and the fragmented metallic waste is loaded into the furnace, downward, from top to bottom, alternately by each layer.
