Matsumoto, Taku; Kato, Masato ; Morimoto, Kyoichi ; Sunaoshi, Takeo*

The oxygen potentials of (U $_{0.623}$ Pu $_{0.35}$ Am $_{0.027}$ )O $_{2{pm}x}$ were measured as a function of oxygen to metal ratio (O/M) in the temperature range from 1673 to 1873 K by the gas equilibrium method using thermogravimetry. The measured oxygen potentials were analyzed by the point defect chemistry method. From this analysis, the oxygen potential of (U $_{0.623}$ Pu $_{0.35}$ Am $_{0.027}$ )O $_{2{pm}x}$ was represented as a function of O/M ratio and temperature.
