· JVASP-24595· Y6UO12

Y6UO12 is an yttrium uranium oxide ceramic compound belonging to the mixed-valence oxide family. While specific industrial deployment data is limited, uranium-yttrium oxides are primarily investigated for nuclear fuel applications, particularly as potential accident-tolerant fuel (ATF) forms and in advanced reactor concepts where enhanced thermal stability and radiation resistance are sought compared to conventional uranium dioxide. This material family is notable for combining yttrium's stabilizing effects with uranium's fissile properties, making it relevant to next-generation nuclear fuel development rather than conventional commercial applications.
