For the disposal of heat-generating radioactive waste, host rocks in Germany include not only salt but also claystone and crystalline rock, where contact between waste forms and deep groundwater is considered realistic. Corrosion of the waste matrix—particularly borosilicate glass—may mobilize radionuclides, with either high initial dissolution rates or significantly lower steady-state rates being observed. While previous studies mainly focused on glass–water interaction, the coupled corrosion of glass and steel remains insufficiently understood. This research is conducted in close collaboration with Forschungszentrum Jülich and GRS – Gesellschaft für Anlagen- und Reaktorsicherheit (Braunschweig) within a joint project funded by the German Federal Ministry for the Environment, Climate Action, Nature Conservation and Nuclear Safety.
