In the present study, as a preliminary stage, to assess the phase stability of MA-containing MOX fuel with a fluorite structure which has a variable composition with oxygen defects in its structure, thermodynamic modeling has been performed for O-Am binary system and O-Pu-Am ternary system on the basis of thermodynamic data available in the literature. The interaction parameters of the excess Gibbs energies of the fluorite structure FCC-C1 phase in O-Am and O-Pu-Am systems were evaluated with respect to the deviation from the ideal solution in oxygen potential, respectively. The thermodynamic modeling used in this study is based on the CALculation of PHAse Diagram (CALPHAD) technique.
