Observation of UO2 Powder Oxidation by X-ray Diffraction
- 1. Kyunghee Univ., Yongin (Korea, Republic of)
Description
As a result, the formation of U3O8 leads to fuel pellet powdering. This volume change by oxidation heavily affects the safety management for the long-time storage and disposal of spent fuel and the integrity of the fuel. The oxidation kinetics of UO2 powders is essential for evaluating long-time integrity maintenance when the dry storage of spent fuel be degraded. In this study, the oxidation kinetics of UO2 powder was analyzed using X-ray diffraction (XRD) systems. In this paper, oxidation experiments with UO2 powder using XRD systems were performed. The results, confirm that the UO2 oxidation proceeds and changes to U3O8. Furthermore, Figure 5 shows that as the temperature increases, the oxidation rate increases, and the oxidation is produced more rapidly in U3O8 from UO2
