| titleOfInvention | Method for producing porous sintered pellets for electrolytic reduction for recovery of metal nuclear fuel, which discontinuously conducts atmosphere sintering and reduction, and porous sintered pellets prepared accordingly |
| abstract | The present invention relates to a method for producing a porous UO 2 sintered pellet for electrolytic reduction for the recovery of metal nuclear fuel, and to a porous UO 2 sintered pellet prepared according to the present invention, in detail oxidizing spent nuclear fuel containing uranium dioxide (UO 2 ) To form a powder comprising U 3 O 8 (step 1); Forming a powder by molding the powder formed in step 1 (step 2); Porous U 3 O 8 prepared in step 2 Sintering the molded body with an atmosphere gas at a temperature of 1200 to 1600 ° C. to produce UO 2 + x sintered pellets (step 3); And cooling the UO 2 + x sintered pellets prepared in step 3 to room temperature, and then reducing them to 1000 to 1400 ° C. in a reducing atmosphere to form UO 2 sintered pellets (step 4). Provided is a method for producing a porous UO 2 sintered pellet for feeding into the electrolytic reduction process. Accordingly, high quality porous UO 2 sintered pellets without cracks or the like can be manufactured. The prepared porous UO 2 sintered pellets can sufficiently remove volatile fission products and have an O / U ratio of 2.00, and include a large number of pores, which facilitate the penetration of electrolytes during the electrolytic reduction process, thereby increasing the rate of electrolytic reduction. have. |
