<p>PROBLEM TO BE SOLVED: To provide a production method for oxide fuel which may be applied to any fuel state of metal fuel reduced from spent oxide fuel and spent metal fuel, is simple in process and cheap in the production cost of fuel formation. SOLUTION: This method is provided with an electrolysis purification process in which metal reduced from spent oxide fuel or spent metal fuel is electrolyzed, uranium and transuranium elements are dissolved in molten salt and are precipitated on a solid cathode or liquid cadmium cathode, an oxidation process making oxidizing gas or steam react to the uranium or transuranium element precipitated on the cathode and recovered and producing oxide, a reducing process reducing the oxide such as produced uranium to dioxide and a fuel production process producing fuel from dioxide stuff. The reducing process may be omitted.</p> |
