A method of manufacturing sintered uranium dioxide in which a mixture is formed of single crystals of uranium dioxide and uranium dioxide powder, compacts are formed from granules of the mixture, the compacts are sintered in carbon dioxide, and then reduced in a hydrogen environment at a substantially lower temperature than the sintering temperature. The quantity of the single crystals is selected so as to inhibit excessive grain growth in the compacts during sintering.
