20090116609 | Method for Operating a Nuclear Reactor and Use of a Specific Fuel Rod Cladding Alloy in Order to Reduce Damage Caused by Pellet/Cladding Interaction - A method for operating a nuclear reactor in order to produce electricity, such that the reactor is controlled so that, during a transient power occurrence for at least one of: a linear power density of the nuclear fuel rod remains lower than a limit linear power density, the limit linear power density being greater than 430 W/cm, and a variation of linear power density of the nuclear fuel rod remains lower than a limit variation, the limit variation being greater than 180 W/cm. | 05-07-2009 |
20130163711 | SOLID INTERFACE JOINT WITH OPEN PORES FOR NUCLEAR FUEL ROD - A new interface between the cladding and the stack of pellets in a nuclear fuel rod. According to the invention, an interface joint made of a material transparent to neutrons, in the form of a structure with a high thermal conductivity and open pores, adapted to deform by compression across its thickness, is inserted between the cladding and the stack of fuel pellets over at least the height of the stack. The invention also relates to associated production methods. | 06-27-2013 |

20120002778 | TRIURANIUM DISILICIDE NUCLEAR FUEL COMPOSITION FOR USE IN LIGHT WATER REACTORS - The present invention relates to nuclear fuel compositions including triuranium disilicide. The triuranium disilicide includes a uranium component which includes uranium-235. The uranium-235 is present in an amount such that it constitutes from about 0.7% to about 5% by weight based on the total weight of the uranium component of the triuranium disilicide. The nuclear fuel compositions of the present invention are particularly useful in light water reactors. | 01-05-2012 |

20100128835 | INTERMEDIATE END PLUG ASSEMBLY FOR SEGMENTED FUEL ROD AND SEGMENTED FUEL ROD HAVING THE SAME - An intermediate end plug assembly for a segmented fuel rod can stably support the fuel rod to the end of its cycle even if an interval between the fuel rods becomes narrow due to application of a dual-cooled fuel rod, and reduce excess vibration induced by flows of interior and exterior channels of the dual-cooled fuel rod for obtaining high burnup and output. To this end, the fuel rod has a segmented structure so as to make its length short. A lower intermediate end plug includes at least one channel hole, through which a coolant flows into an internal channel of the fuel rod, so that a possibility of causing departure from nuclear boiling ratio (DNBR) of the dual-cooled fuel rod is reduced. | 05-27-2010 |
20120002777 | TRIURANIUM DISILICIDE NUCLEAR FUEL COMPOSITION FOR USE IN LIGHT WATER REACTORS - The present invention relates to nuclear fuel compositions including triuranium disilicide. The triuranium disilicide includes a uranium component which includes uranium-235. The uranium-235 is present in an amount such that it constitutes from about 0.7% to about 20% by weight based on the total weight of the uranium component of the triuranium disilicide. The nuclear fuel compositions of the present invention are particularly useful in light water reactors. | 01-05-2012 |
20120263271 | NUCLEAR FUEL - A nuclear fuel pellet design that is a cylindrical axial profile with either a larger radius or conical shaped ends such that the as built diameter at the ends of the pellet are slightly smaller than at the middle and at normal operating conditions, the diameter at the ends is nearly the same as at the middle. Preferably, there are short chamfers at the axial ends of the pellet. | 10-18-2012 |
20130322591 | FUEL ASSEMBLY - Nuclear fuel assemblies include fuel elements that are sintered or cast into billets and co-extruded into a spiral, multi-lobed shape. The fuel kernel may be a metal alloy of metal fuel material and a metal-non-fuel material, or ceramic fuel in a metal non-fuel matrix. The fuel elements may use more highly enriched fissile material while maintaining safe operating temperatures. Such fuel elements according to one or more embodiments may provide more power at a safer, lower temperature than possible with conventional uranium oxide fuel rods. The fuel assembly may also include a plurality of conventional UO2 fuel rods, which may help the fuel assembly to conform to the space requirements of conventional nuclear reactors. | 12-05-2013 |
20140307845 | Composite Fuel Rod Cladding - A fuel rod for a nuclear fission reactor is disclosed and claimed. The fuel rod includes an elongate hollow cladding configured to retain a nuclear fuel therein. The cladding includes an elongate hollow tube. Fiber layers are positioned around the outside surface of the tube or within the tube forming an integral part thereof. Both the tube and the fibers are formed of a ceramic material. A fuel assembly including a plurality of such fuel rods is also disclosed and claimed. | 10-16-2014 |
