| titleOfInvention | METHOD FOR PREPARING POROUS NUCLEAR FUEL BASED ON THE LESSER OF ONE JUNIOR ACTINIDE |
| abstract | 1. A method of producing a porous fuel containing uranium, optionally plutonium and at least one minor actinide, comprising the following successive steps: a) a tablet compaction step of a powder mixture containing uranium oxide, optionally plutonium oxide and at least one minor actinide oxide wherein at least a portion of the uranium oxide is in the form of triuranium octaoxide UO, and the other part is in the form of uranium dioxide UO; b) a step for reducing at least a portion of triurana octaoxide UO to uranium dioxide UO.2. The method according to claim 1, wherein the minor actinide oxide is selected from the group consisting of americium oxide, curium oxide, neptunium oxide, and mixtures thereof. The method according to claim 1, wherein the uranium oxide in the form of triuran octaoxide UO is bound inside the same grains with minor actinide oxide and optionally with plutonium oxide, said grains having a size of more than 100 μm, preferably from 100 to 250 μm. The method according to claim 1, further comprising before the compaction step a) a step for producing said powder mixture used in step a). The method according to claim 4, wherein the step of preparing the powder mixture comprises combining a first mixture containing uranium oxide powder in the form of uranium dioxide UO, optionally plutonium oxide and at least one minor actinide oxide powder, and a second mixture of powders containing uranium oxide in as triurana octaoxide UO, optionally plutonium oxide and minor actinide oxide. 6. The method according to claim 5, in which the second mixture of powders consists of grains combining inside the same grain triuranium octaoxide UO, optionally plutonium oxide and minor actinide oxide, wherein said grains have |
