Variations in the composition of U 0.75 Pu 0.25 O 2‐x as a function of the oxygen potential were determined by a thermogravimetric technique over the interval 950° to 1400°C. Oxygen potentials ranging from ‐100 to ‐155 kcal/mol were established by means of H 2 O‐H 2 ‐O 2 equilibria. The partial molar enthalpy and entropy of solution of O 2 in the mixed oxide fuel were independent of temperature over the interval investigated but varied with the composition of the fuel.
