Abstract
The objective of this report is to assess the long-term stability of high-level waste glass in the geological disposal conditions of the Boom clay formation (Mol site, Belgium). In particular, research efforts were concentrated on the measurement of the dissolution rate of high-level waste glass in the presence of the host rock (Boom clay) and engineered barriers. The influence of three candidate backfill materials (bentonite, sand, and concrete) on the dissolution rate is assessed. The dissolution rate of high-level waste glass is measured by performing leaching experiments in the presence of claywater, Boom clay, and various canister, overpack, and backfill materials. These corrosion tests were carried out at 90 degrees Celsius and at different exposed surface area to volume ratios, namely 10 m{sup -1}, 100 m{sup -1}, and 1000 m{sup -1}. The duration of the tests varies from 30 to 90 days. From the experimental results is concluded that the dissolution of the Pamela/DWK SM513 glass is not affected by the presence of the three candidate backfill materials while in the presence of concrete, the dissolution of the glass is reduced in the short-term. (A.S.).
