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...

2017:25 Evaluation of weld fatigue reduction in austenitic stainless steel pipe components
Anderson SSM 2017:25 SSM 2017:25 SSM perspective Background The performed investigation is a continuation of the work performed in SSM 2015:38 where fatigue tests were performed on pressurized ... with mainly reversed bend- ing deformation and particular focus on high cycle fatigue. The previous fatigue results were quite dependent on the estimation of the stress con- centration factor of the weld...
