The possible application of thermogravimetry, gas chromatography, hydriding-dehydriding, and emf of a high-temperature solid-electrolyte galvanic cell to the determination of the O/U atomic ratio in UO{sub 2-x} is investigated. The studied methods have an analytical uncertainty of {+-} 0.001 O/U units. However, the emf method, which is highly accurate near the stoichiometric composition, is applicable only for homogeneous UO{sub 2-x}. The useful range of the emf method can be expanded for analyzing substoichiometric UO{sub 2}.
