摘要

Although the glass materials have much better properties (e.g. leachability and mechanical strength) compared to the conventional immobilizing agents (e.g. cement, concrete, etc.), it is reported that the glass dissolution would take place through metal leaching. Therefore, it is necessary to assess the long-term safety of the vitrified LLW in the final geologic disposal repository. Lots of thermodynamic and kinetic glass dissolution models have been developed and proposed. However, most of them have some limitations and uncertainties. The conventional glass dissolution models have often overestimated the long-term dissolution phenomena which can be observed in natural systems.
