Abstract
Experiments on leaching of borosilicate glass samples containing 10, 15, and 20 wt % simulated high-level waste (HLW) were performed at 20 and 90°C in hydrogen peroxide solutions. H2O2 was used as a substance simulating products of underground water radiolysis. The leach rates and diffusion coefficients of the glass components were determined. The character and extent of the effect of the varied experimental parameters on the characteristics being determined were evaluated by correlation analysis. The presence of hydrogen peroxide in the contact solution enhances the chemical durability of borosilicate glasses.
