The fuel for the Xe-100 is a spherical fuel element, or pebble, that utilizes the tristructural isotropic particle nuclear fuel design, with high-assay LEU (HALEU) uranium fuel enriched to 20%, to allow for longer periods between refueling. [7] X-energy claims that TRISO fuel will make nuclear meltdowns virtually impossible. [citation needed]
