Abstract

The main objectives of this four-stage project were to complete the experimental approaches observed in previous programmes and to make use of the data obtained to develop models for long-term predictions of radioactive waste glass stability in possible geological environments.

Tests on inactive waste glass samples were performed in various geological liquid media with high glass surface area to solution volume ratio (SA/V) under different conditions of temperature.

A second group of experiments concentrated on accelerated and integrated corrosion tests on glasses doped with the major actinides and in contact with synthetic clay-water or a clay/clay-water/canister corrosion products mixture.

As part of the effort to model glass corrosion in Boom clay, flow-through migration tests have been carried out to determine the diffusion coefficient of silica and the extent of its sorption on Boom clay.

The data obtained from the corrosion tests will be incorporated into models which are under development to evaluate the long-term performance of waste glasses in geological experiments. iments.
