FIELD: physics.
SUBSTANCE: method of handling reactor graphite shutdown uranium-graphite reactor includes sampling of masonry of the reactor. Graphite blocks are mechanically. Milled pieces are placed in a plasma-chemical reactor as consumable electrodes. Material of consumable electrodes evaporated. In the area of low-temperature plasma is introduced oxidant. Is quenching products plasma-chemical reaction. Reaction products are concentrated on reactor walls. Gaseous reaction products are removed from the reactor. Part of the gas flow are looped and supplied together with an oxidant in reactor. Gaseous reaction products except carbon oxides are caught in the scrubber. Carbon oxides are converted into liquid phase and delivered for further burial. Solid ash residues removed from plasma chemical reactor.
EFFECT: invention makes it possible to clean radioactive graphite from fission products and activation for further safe storage.
