Collaborative study has been done on the properties of nuclear materials between the DOE and Japan and the oxygen potential of (U,Ce)O was measured in this year. Experimental measurements of the oxygen potential were conducted on Ce=20% and 30% composition rates simulating Pu content in advanced MOX fuel in JAEA by gas equilibrium method where oxygen partial pressure in the atmosphere was controlled with mixing dry/wet Ar/H
gas. More than 100 data points were obtained in the O/M range of 1.945
2.000 at 1200
C, 1400
C and 1600
C. The experimental results were analyzed by the defect analysis and analytical equations were obtained to calculate O/M as functions of temperature and oxygen potential. From the comparison with that of (U,Pu)O
, applicability of the same defect chemistry and S-style curve are common. Also, it is revealed that (U,Ce)O
requires evidently higher oxygen potential for the O/M.
