LEACHING OF BOROSILICATE GLASS IN CONFINED SYSTEMS
A series of tests of leaching glass cylinder and glass granules in distilled water has been performed using a procedure similar to the MCC-1 as proposed by PNL. Different ratios of exposed glass surface to leachate volume, and namely 0.22; 0.33; 0.5; 1.95 were utilized. Tests were performed at 40, 70 and 90 degrees C. Glass cylinders were exposed up to a maximum of 130 days while glass granules up to a maximum of 28 days. Analysis of the leachate allowed to evaluate the release of silicon, boron and sodium. The results obtained were analyzed in order to determine if in the leaching process dissolution or diffusion was the rate determining mechanism. A discussion on the influence of silicon dioxide saturation in the leachate is also performed.
