FIELD: power industry.;SUBSTANCE: treatment method of radioactive contaminated metal and graphite wastes of uranium-graphite nuclear reactors involves loading of radioactive contaminated metal wastes and flux to oven, melting of metal wastes, and removal of molten metal and formed slag flux from the oven. Before radioactive contaminated metal wastes are loaded to the oven there loaded is layer of radioactive contaminated graphite and it is ignited in oxidising medium with plasma generated by plasmatron of the oven; after that, plasmatron is switched off and loading of fragmented radioactive contaminated metal wastes and flux are loaded to the furnace downwards and layer by layer.;EFFECT: invention allows minimising the volume of secondary radioactive wastes, reducing energy consumption and excluding the possibility of occurrence of emergency situation.;1 dwg
