FIELD: power industry.
SUBSTANCE: method involves combined separation of all actinoid (III), (IV), (V) and (VI) components present in strongly acidic water phase from fission products, namely lanthanides also present in that phase, by means of solvating extractant in salting-out medium.
EFFECT: invention allows catching all other actinoids from solution for decomposition of irradiated nuclear fuel pre-cleaned from uranium contained in it using the combined method which is selective in relation to fission products.
