| titleOfInvention | Renewal nuclear fuel assembly (1320) and depleted uranium oxide extractor. |
| abstract | PROBLEM TO BE SOLVED: To provide a method for treating and disposing of spent nuclear fuel of uranium oxide. SOLUTION: A new cladding tube 241 having the same outer diameter and length as the used cladding tube in the original nuclear fuel rod and having a thin wall thickness, and a used nuclear fuel pellet 144 in the original nuclear fuel rod are inserted, and a new spring 244 is mounted. Provided is a renewal nuclear fuel assembly using a renewal nuclear fuel rod 250 in which a new upper end plug 242 and a new lower end plug 243 are connected after being filled with helium. The spent nuclear fuel oxide is further burned in the same type of BWR to deteriorate it into depleted uranium oxide and lower plutonium oxide. The decay heat of the spent nuclear fuel oxide is heated by a heater to melt the lower plutonium oxide, and the depleted uranium oxide from which Pu has been removed from the spent nuclear fuel oxide is used for the artificial ground.
