FIELD: chemistry.
SUBSTANCE: invention relates to the technology of recycling nuclear energy materials and specifically to methods of cleaning uranium hexafluoride from ruthenium fluorides, and can be used in returning uranium, extracted from spent nuclear fuel, into the fuel cycle of light water reactors. The method of cleaning uranium hexafluoride from ruthenium fluorides involves reaction of gaseous uranium hexafluoride with a sorbent, the sorbent used being porous granules of sintered metal powder of nickel or nickel which contains up to 10 wt % copper.
EFFECT: invention provides efficient cleaning of uranium hexafluoride from ruthenium fluorides at low temperatures, safety and simplification of the process, and also enables to reuse the sorbent after regeneration.
