Portions of the cesium-uranium-oxygen system have been investigated between 873 and 1273/sup 0/K and a phase diagram has been constructed using our data and the data of other workers in the field. Thermodynamic and kinetic data have been used to examine the reactions that occur in fast-reactor fuel pins between fission-product cesium and the uranium oxide blanket. It was concluded that at the low oxygen potentials existing at the interface between the uranium-plutonium mixed-oxide and the uranium oxide blanket, Cs/sub 2/UO/sub 4/ is the only Cs-U-O compound expected to be formed in the uranium oxide blanket.
