Description

The effects of Al2O3-SiO2 and NiO-SiO2 on creep property of UO2 pellet have been studied. The creep rate of UO2 pellets with additives was slower than that of pure UO2 pellets at low stress and small amount of additives, but it faster at high stress and large amount of additives. Especially, the creep rate of UO2 pellets with 0.2wt% Al2O3-SiO2 or NiO-SiO2 at a stress of 65MPa was higher by factors of 1.5∼4 than that of pure UO2 pellet. The enhanced creep rate might be attributed to the secondary phase which has formed on grain boundary through liquid phase sintering
