A literature survey on the surface science of water adsorption on Cu

The method chosen by Posiva Oy (Finland) and Svensk Kärnbränslehantering AB (Sweden) for the final disposal of spent nuclear fuel is the KBS-3 method. It entails storing spent nuclear waste underground in canisters that have a protective exterior made of copper (Cu). At present, there is controversy over the extent of corrosion of Cu in anoxic water. Recent results suggest that Cu can corrode in anoxic water to a much larger extent than what has been predicted earlier.

A wealth of information exists on water-Cu interaction. Most of it has been acquired by using surface scientific means. This report reviews the recent experimental and theoretical results obtained on water-Cu interaction mechanisms.
