The invention relates to a method for producing a porous fuel including uranium, optionally plutonium, and optionally at least one minor actinide, which includes the following series of steps: a) a step of compacting a mixture including a first type of agglomerate including uranium oxide in the form of uranium dioxide UO 2 , optionally plutonium oxide, and optionally at least one minor-actinide oxide, and a second type of agglomerate including uranium oxide in the form of triuranium octaoxide U 3 O 8 , optionally plutonium oxide, and optionally at least one minor-actinide oxide; b) a step of reducing the compacted mixture in a reducing medium so as to reduce all or part of the triuranium octaoxide U 3 O 8 into uranium dioxide UO 2 , the second type of agglomerate being prepared prior to the compacting step by a series of specific operations. |
