Oxygen potential measurement and point defect chemistry of UO $_{2}$

Watanabe, Masashi ; Kato, Masato ; Sunaoshi, Takeo*

Many studies on the oxygen potential of UO $_{2}$ have been carried out so far. However, the oxygen potential data for UO $_{2}$ near the stoichiometric composition in the high temperature region (1673-1873 K) are limited. In this work, the oxygen potential data of UO $_{2+x}$ were extended to high temperature range of 1673-1873 K by gas equilibrium method. The measured data were analyzed based on a defect chemistry model.
