Abstract

Static corrosion tests were performed on the simulated waste glass dopedwith Pu and Cm (PuO2; 0.22wt%, Cm2O3;0.09%) in deionized water at 90 °C with S/V ratio of 2600 m−1under oxidizing and reducing conditions, respectively. The corrosion testsunder oxidizing conditions were performed in air, while the corrosion testsunder reducing conditions were performed in an airtight stainless steelcontainer purged with mixed gas (Ar+5%H2), where the Eh of the solution wasmaintained at approximately -0.45 V vs SHE. The results showed that theredox conditions have no remarkable influence on the leaching behavior of Puand Cm. It was also observed that the Pu and Cm concentrations in the 1.8nmfiltered solutions were one or two orders of magnitude lower than those inthe 450nm filtered solutions under both redox conditions, which suggeststhat the insoluble suspended fractions (colloidal particles) with the sizefrom 1.8nm to 450nm are dominant phase for Pu and Cm in the solution underboth redox conditions.
