摘要： 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.

摘要： A method of manufacturing a fuel assembly for use in a core of a nuclear power reactor. The method includes manufacturing each of a plurality of elongated fuel elements by mixing powdered fuel material with powdered metal non-fuel material. The mixed powdered fuel material and metal non-fuel material is sintered to create a fuel core stock, the fuel core stock is surrounded with a cladding material, and the fuel core stock and cladding material are co-extruded to create the fuel element. The fuel element has a spirally twisted, multi-lobed profile that defines a plurality of spiral ribs. The multi-lobed profile includes lobe tips and intersections between adjacent lobes. The cladding is thicker at the tips than at the intersections. The plurality of elongated fuel elements are mounted to a frame of the fuel assembly. A moderator:fuel ratio in a region of the fuel elements is 2.5 or less.
