Pyrochlore-type (P-type) zirconia has been widely studied as a disposable form of the high-level radioactive nuclear waste. We have developed the EMF (electromotive force) measurement system using the cubic zirconia sensor, in order to investigate the oxygen potential (g(O $_{2}$ )) of P-type Zr $_{2}$ Pu(Ce) $_{2}$ O $_{7+x}$ . For P-type Zr $_{2}$ Ce $_{2}$ O $_{7+x}$ at 1078 K, we have found that g(O $_{2}$ ) vs. oxygen composition (x) relationship has different behavior between x more than 0.34 and x less than 0.34. This may suggest that the degree and way of the ordering of oxide ions (O $^{2-}$ ) and oxygen vacancies (V0) should change around x =0.34. We have also measured the g(O $_{2}$ ) vs. temperature (T) relationship between 763 and 1078 K at various x, and derived the partial molar enthalpy (h(O $_{2}$ )) and entropy (s(O $_{2}$ )) of oxygen. It was found that h(O $_{2}$ ) and s(O $_{2}$ ) of P-type Zr $_{2}$ Ce $_{2}$ O $_{7+x}$ exhibit significantly different behavior from those of fluorite-type CeO $_{2-x}$ . The similar experiments are in progress for P-type Zr $_{2}$ Pu $_{2}$ O $_{7+x}$ , and the results are discussed in comparison with those of P-type Zr $_{2}$ Ce $_{2}$ O $_{7+x}$ mentioned above.
