A method for manufacturing a porous fuel comprising uranium, optionally plutonium and at least one minor actinide is provided. The method may comprise the following successive steps: a) a step for compacting as pellets a mixture of powders comprising uranium oxide, optionally plutonium oxide and at least one oxide of a minor actinide, at least one portion of the uranium oxide being in the form of triuranium octaoxide U 3 O 8 , the other portion being in the form of uranium dioxide UO 2 ; b) a step for reducing at least one portion of the triuranium octaoxide U 3 O 8 into uranium dioxide UO 2 . |
