Comparing the corrosion of uranium nitride and uranium dioxide surfaces with H2O2
Abstract
<p>Uranium mononitride, UN, is considered a potential accident tolerant fuel due to its high uranium density, high thermal conductivity, and high melting point. Compared with the relatively inert UO<sub>2</sub>, UN has a high reactivity in water, however, studies have not considered the significant effect of radiation, which is known to cause corrosion of UO<sub>2</sub>. This study uses 0.1 M H<sub>2</sub>O<sub>2</sub>to simulate the effects of water radiolysis in order to compare the radiolytic corrosion rates of UO<sub>2</sub>, UN, and U<sub>2</sub>N<sub>3</sub>thin films at room temperature. X-ray reflectivity was used to investigate the changes in film morphology as a function of H<sub>2</sub>O<sub>2</sub>exposure time, allowing changes in film thickness and roughness to be observed on the Ångstrom length-scale. Results showed significant differences between UO<sub>2</sub>, UN, and U<sub>2</sub>N<sub>3</sub>, with corrosion rates of 0.083(3), 0.020(4), and 0.47(8) Å/s, respectively, showing that UN corrodes more slowly than UO<sub>2</sub>in 0.1 M H<sub>2</sub>O<sub>2</sub>.</p>
