現在までUO$$_{2}$$の酸素ポテンシャルについての研究は多くなされているが、高温領域(1673-1873K)における定比組成近傍の酸素ポテンシャルデータは非常に少ない。そこで本研究では、1673-1873KにおけるUO$$_{2+x}$$の酸素ポテンシャルデータの拡充を図るとともに、欠陥化学モデルを用いてデータの解析を実施した。

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.
