Abstract
The kinetic changes of air-oxidation of UO2 by additive addition and irradi ation were investigated. Several kinds of specimens, such as unirradiated-U O2 simulated-UO2 for spent PWR fuel (SIMFUEL), unirradiated-Gd-doped UO2, i rradiated-UO2 and -Gd-doped UO2 were used for these experiments. The oxidat ion results represented that the kinetic patterns among those samples are r emarkably different. Ir was also revealed that, the oxidation kinetics of i rradiated UO2 seems to be more similar to that of unirradiated-Gd-doped UO2 than that of SIMFUEL. (C) 2000 Elsevier Science B.V.
