Abstract: A locking mechanism (95, 125, 130) for a nuclear fuel assembly (2) having seed and blanket (6) subassemblies is configured to selectively lock the seed subassembly within the blanket subassembly, preventing separation thereof. The locking mechanism contains one or more detents (95) on one of the seed subassembly or the blanket subassembly, that are configured to engage with a surface feature on the other of the seed subassembly or the blanket subassembly. The locking mechanism contains a locking member movable between two positions. In a first position, the locking member (100) is configured to prevent the one or more detents from disengaging from the surface feature (125, 130), thereby holding the blanket subassembly and the seed subassembly together. In a second position, however, the detents are able to move into a non- locking position, such that the one or more detents may disengage from the surface feature as the seed subassembly is separated from the blanket subassembly.

Abstract: Nuclear fuel assemblies for use in nuclear power plants include all-metal fuel elements that are sintered or cast into billets and co-extruded into a spiral, multi-lobed shape. The increased thermal transfer properties of such fuel elements relative to conventional cylindrical uranium oxide fuel rods increases the amount of heat that can be transferred to the coolant at a lower fuel element temperature. The metal fuel elements may use more highly enriched fissile material while maintaining safe operating temperatures. Such metal 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, fuel elements, and/or fuel kernels may include burnable poison. The fuel assembly may also include a plurality of conventional U02 fuel rods, which may help the fuel assembly to conform to the space requirements of conventional nuclear reactors.

Abstract: 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.
