Synthetic Groundwater

To understand the influence of cations and silica in groundwater on spent fuel corrosion, the leaching behavior of newly reduced UO2.00 in different solutions was investigated. Uranium concentrations in the solutions were measured and the leached UO2 surface and precipitates on it were analyzed by XPS, laser Raman spectroscopy, SEM-EDS and TEM-EDS. It was found that, in air saturated 2 mM HCO3- solutions, the leaching rates of UO2(s) depend on the composition of the leaching solutions. Very similar leaching rates, 0.5 μg • cm-2 • day-1, were obtained in 0.1 M NaCl and 0.1 M KCl solutions, while that in 0.45mM Ca2+ -0.18 mM Mg2+ -0.2 mM SiO2 containing synthetic groundwater was 10 times smaller. Calcite and quartz like precipitates were detected on the corroded UO2(s) surface.
