Description

The results from the JSS phase II static glass leaching experiments are presented. The experiments have been performed in the presence of bentonite, granite and stainless steel corrosion products at 900C for 28 days. The leaching behavior of Cs has been analyzed using gamma-spectrometry. The surface of the leached glass samples has been analyzed by infrared reflection spectrometry. The presence of uncompacted bentonite seems to have a very small, increasing, effect on the leach rate of the glass compared to when no bentonite is present. In the presence of compacted bentonite, a lower leach rate has been found than in the presence of uncompacted bentonite. (For Cs 0.3 g x m-2 x d-1 and 0.7 g x m-2 x d-1 respectively.) The addition of stainless steel corrosion products seems to have a slightly increasing effect on the leach rate in the presence of compacted bentonite. The beneficial effect of granite on the leach rate seems to be overshadowed by the presence of uncompacted bentonite
