核燃料の挙動を理解するうえで酸素の拡散現象は非常に重要である。これは核燃料の焼結、蒸発、酸素再分布及び核分裂生成物の形成といった現象と酸素拡散が密接に関連していることに由来する。そこで、本研究では(U, Pu)O$$_{2}$$中における酸素の自己、化学拡散係数を高温下で高精度に測定し、両者の関係を評価した。

Diffusion phenomena of oxygen in mixed oxide fuel are especially important in understanding fuel behaviour. The reason is that sintering, evaporation, oxygen redistribution and behaviour of fission products are essentially involved in the oxygen diffusion process. Thus, the purpose of this work is to precisely measure the oxygen self and chemical diffusion coefficients in (U, Pu)O$$_{2}$$ at high temperatures and to evaluate the relationship between both coefficients.
