“…The LEU fuel currently under consideration is a high-density monolithic alloy, U-10Mo, which contains 90 wt % uranium and 10 wt % natural molybdenum. It has a density of 17.02 g/cm 3 and an enrichment of 19.75 wt % 235 U. As included in the key top-level assumptions established to guide the HFIR conversion study, 3 there shall be no change in the physical dimensions of the core or fuel geometry, no reduction in the core power or core lifetime, and no major changes to the current control and protection systems, and the margins of safety in the bases of the currently approved Technical Safety Requirements 4 shall be maintained.…”

The fuel meat is the region that will need to be changed when the current HEU fuel is replaced with LEU fuel, with no changes to the basic geometry of the fuel plate.…”
