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.
