Zusammenfassung:	FIELD: nuclear engineering; methods of processing of the solid radioactive waste. ^ SUBSTANCE: the invention is pertaining to the field of nuclear engineering, to the methods of processing of the solid radioactive waste, in particular, to the methods of processing of the metallic waste containing radionuclides. The method of processing of the metallic waste containing radionuclides includes the waste smelting and the metal casting. At that the processing includes in two phases. At the first phase the waste is subjected to a thermal decontamination in the open air at the temperature of 450 - 700°C. At the second phase conduct the waste smelting under vacuum at a heating rate of 300 - 450°C per hour, then the melt is aged for 10-20 minutes and cast in a mold. The invention ensures reduction of contamination of the gained metal. ^ EFFECT: the invention ensures reduction of contamination of the gained metal. ^ 1 tbl, 1 ex
