The hydrothermal synthesis of pure uranium dioxide under supercritical water (SCW) conditions was investigated. The nonstoichiometry, crystallite size and morphology of the UO$$_{2+x}$$ particles were investigated. The SCW hydrothermal synthesis may be a promising method for producing homogeneous UO$$_{2+x}$$ and its solid solutions with well-defined nonstoichiometries ($$x$$), shapes, and sizes.
