高速炉燃料として開発が進められている(Pu$$_{0.2}$$U$$_{0.8}$$)O$$_{2-x}$$及び(Np$$_{0.02}$$Am$$_{0.02}$$Pu$$_{0.3}$$U$$_{0.66}$$)O$$_{2-X}$$の酸素ポテンシャルを1473$$sim$$1623Kの温度で、気相平衡法により測定した。(Pu$$_{0.2}$$U$$_{0.8}$$)O$$_{2-x}$$の酸素ポテンシャルは(Pu$$_{0.3}$$U$$_{0.7}$$)O$$_{2-x}$$に比べ約25kJ/molK低い結果を得た。(Np$$_{0.02}$$Am$$_{0.02}$$Pu$$_{0.3}$$U$$_{0.66}$$)O$$_{2-X}$$の酸素ポテンシャルは、MAが含んでいない試料に比べてわずかに高い値であった。

Oxygen potentials of homogenous (Pu$$_{0.2}$$U$$_{0.8}$$)O$$_{2-x}$$ and (Np$$_{0.02}$$Am$$_{0.02}$$Pu$$_{0.3}$$U$$_{0.66}$$)O$$_{2-X}$$ which have been developed as a fuel of fast breeder reactors were measured at temperatures of 1473 - 1623 K by gas equilibrium technique using Ar/H$$_{2}$$/H$$_{2}$$O gas mixture. Oxygen potentials of (Pu$$_{0.2}$$U$$_{0.8}$$)O$$_{2-x}$$ measured in this work were about 25 kJ/mol lower than those of (Pu$$_{0.3}$$U$$_{0.7}$$)O$$_{2-x}$$ and were consistent with the value calculated by Besmenn and Lindemer's model. Those of (Np$$_{0.02}$$Am$$_{0.02}$$Pu$$_{0.3}$$U$$_{0.66}$$)O$$_{2-X}$$ were slightly higher than those of MOX without minor actinides.
