Corrosion of Steels in Anaerobic, Unsaturated Deep Geological Repository Conditions
Various countries, including Canada, are considering carbon steel as a candidate corrosion barrier material for isolating used nuclear fuel in a deep geological repository (DGR) in sedimentary rocks. Carbon steel containers are also used in low and intermediate level waste underground repositories, including the proposed Canadian DGR. Most existing corrosion studies of carbon steel focus either on the aerobic or anaerobic, saturated conditions. However, in a DGR in a low-permeability host rock, the conditions may be anaerobic and humid but not saturated for extended periods. Corrosion data of carbon steel under these conditions is limited. The current knowledge of hydrogen effect on anaerobic unsaturated corrosion rate and corrosion potential are also poor.
This investigation aims at collecting realistic hydrogen generation data using advanced gas detection techniques. Empirical data obtained will then be used to develop deterministic models which will allow the prediction of the evolution of long term corrosion damage of carbon steel.
