Short summary

The aims of the project are to confirm the long-term anaerobic corrosion rate of carbon steel and copper in compacted bentonite under repository-relevant environmental conditions. Low average anaerobic corrosion rates were measured for carbon steel and a very modest amount of alteration was identified on copper.
