Neptunium of minor actinide nuclides separated from spent fuel is added to fuel of reactor cores (inner reactor cores and/or outer reactor cores) of a fast reactor and americium of the separated minor actinide nuclides and rare earth elements are added to either or both of radial and axial blankets of the fast reactor for burning. Thus, the minor actinide nuclides with long half-lives can be burnt with the fast reactor core with the minimized effects of the rare earth elements. For a burner reactor, americium and rare earth elements may be added to shields for burning. Curium may be added together with americium and rare earth elements. Neptunium is added in amount of 2% to 5% by weight based on the weight of the fuel and the rare earth elements are added in an amount of 50% by weight or less based on the weight of the fuel. A Purex process is used to separate neptunium and a Truex process is used to separate americium and curium.
A method of minor actinide nuclides incineration by adding neptunium of minor actinide nuclides separated from spent fuel to reactor core fuel of a fast reactor and adding americium of the separated minor actinide nuclides and rare earth elements to either or both of radial and axial blankets of the fast reactor for nuclear reaction.
A method of minor actinide nuclides incineration by adding neptunium of minor actinide nuclides separated from spent fuel to reactor core fuel of a fast reactor and adding americium of the separated minor actinide nuclides and rare earth elements to either or both of radial and axial shields of the fast reactor for nuclear reaction.
A method for an efficient nuclear reaction of americium and curium in a mixture of americium, curium, and rare earth elements, said method comprising the steps of adding neptunium to reactor core fuel of a fast reactor and placing said mixture on the periphery of the reactor core fuel to which said neptunium is added for causing a nuclear reaction to occur, whereby an efficient nuclear reaction can be caused to occur for americium and curium in said mixture for efficiently making said elements in said mixture incinerate.
A method of making americium and curium incinerate, comprising the steps of:
