writes Swedish Nuclear Fuel and Waste Management Company, SKB, in a press release on the occasion of the company’s latest report to the SSM.

– Our assessment is that the scientific support for the existence of a corrosion process of copper in oxygen-free water has weakened further with the results we now see, says Allan Hedin, head of safety at SKB.

Tubes Attempts made for Microbial Analysis AB in Gothenburg have shown that there is no hydrogen evolution at all for copper with ultra-clean surface. This, together with the results of experiments at the Ångström Laboratory in Uppsala, SKB believes indicate that the hydrogen found in other experiments comes from short-term reactions to the copper surface.

SKB to provide additional a progress report on research findings from micans in Gothenburg and the Ångström Laboratory at SSM summer of 2014.
