FIELD: technological processes.
SUBSTANCE: invention relates to a method of producing porous fuel containing uranium, optionally plutonium and optionally at least one minor actinide, which includes following sequence of steps: a) a step of compacting a mixture including a first type of agglomerate including uranium oxide in form of uranium dioxide UO2, optionally plutonium oxide, and optionally at least one minor-actinide oxide, and a second type of agglomerate including uranium oxide in form of triuranium octaoxide U3O8, optionally plutonium oxide and optionally at least one minor actinide oxide; b) a step of reducing compacted mixture in a reducing medium so as to reduce all or part of triuranium octaoxide U3O8 into uranium dioxide UO2, second type of agglomerate being prepared prior to compacting step by a series of specific operations.
EFFECT: technical result is prevention of degradation of pore-forming material at step of mixing fuel precursors, possibility of controlling porosity both in qualitative and quantitative ratio.
