Comparison of the properties of ex-DC and -AUC UO2 pellet

  • 1. KNFC, Taejon (Korea, Republic of)

Description

Properties of the DC and AUC pellets which were supplied to the commercial reactors in Korea had been evaluated. Ex-DC UO2 powder showed lower specific surface area than ex-AUC UO2 powder due to its morphology. Since surface area of ex-AUC UO2 powder was large, it had more chance to oxidation. This leaded to raise O/U ratio. Apparent density of granulated ex-DC UO2 powder was similar to ex-AUC UO2 powder. There was no great difference in sintered density between DC and AUC pellet though DC pellet contained more U3O8 and was sintered at lower temperature than AUC pellet. DC and AUC pellets showed similar grain size and their average size was about 7.5μm. DC pellet absorbed less hydrogen than AUC pellet
