2011:34 Evolution of hydrogen by copper in ultrapure water without dissolved oxygen
Becker Hans-Peter Hermansson Research SSM perspective Background The KBS-3 repository concept developed by SKB for disposal of spent nuclear fuel is based on a multi barrier principle for isolation ... isolation of the fuel and to delay any escaping radionuclides. The concept is based on three barriers; copper canister, bentonite buer and granitic bedrock. The copper canister will in this respect work as...
