Abstract
A fuel assembly includes a plurality of elongated fuel elements. Each of the plurality of fuel elements has a spirally twisted, multi-lobed profile that defines a plurality of spiral ribs. Each of the plurality of fuel elements has a fuel kernel that includes fuel material disposed in a matrix of metal non-fuel material. The fuel material includes fissile material. A cladding surrounds the fuel kernel. A moderator: fuel ratio in a region of the fuel elements is 2.4 or less. The moderator: fuel ratio is an area ratio within a cross-section that is perpendicular to longitudinal axes of the plurality of fuel elements and extends through the plurality of fuel elements. The area ratio is a ratio of: (1) a total area available for moderator flow for the plurality of fuel elements to (2) a total area of the fuel kernels of the plurality of fuel elements.
