THEREDA represents a web-based system of programs enabling access to thermodynamic reference data for the needs of the final disposal of radioactive waste in Germany. It is the only polythermal database worldwide that covers the entire system of oceanic salts, including acids, bases and carbonates. THEREDA aims at calculation of solubilities in high-saline solutions and uses the Pitzer approach.

The talk presents highlights from the generic identification and evaluation of processes for co-disposal of high-level radioactive waste and low- and intermediate-level radioactive waste in clay rock, crystalline rock and salt rock in the context of the German site-selection process for a deep geological repository for high-level radioactive waste on behalf of the Federal Office for the Safety of Nuclear Waste Management (BASE).

Short summary
It has been recently recognized that the availability of liquid water may be a controlling factor for metal corrosion in a storage facility for radioactive waste. Since water is an educt for anaerobe corrosion, the reaction may be suspended or suppressed by the scarcity of water near the corroding surfaces. Gas pressure build-up through hydrogen generation may limit further water ingress. Our model focuses on the close coupling between gas generation through iron corrosion and water availability.
