2012:21 Technical Note, Initial Review Phase for SKBs Safety Assessment SR-Site: Corrosion of Copper
The uniform and localized corrosion treatments as well as stress corrosion cracking positions currently considered by SKB have been examined with the objective of identifying key unresolved issues or gaps ... gaps, needs and opportunities. In conjunction with the review of the SKB reports listed in Appendix 1, there has been some consideration of the broader literature. This summary highlights the main review...

2012:20 Report from SSM’s scientific council on ionizing radiation within oncology, 2011
council states that the radiotherapy part in those guidelines and protocols is less well specified than other therapies such as surgery and chemotherapy. This report identifies the key aspects of modern ... organisations and scientific papers in order to develop written radiotherapy guidelines and clinical trial protocols. Associated relevant information to be listed in protocol templates are analyzed and discussed...

2012:18 Technical Note, SR-Site Independent Modelling of Engineered Barrier Evolution and Coupled THMC: Contribution to the Initial Review Phase
thermal, hydraulic, mechanical and chemical (THMC) processes. Additionally, the role of the EBS in the wider safety case was reviewed, including its treatment in scenarios and its representation in conceptual ... The scope of the work described here was to: Review relevant documents concerning SKB’s modelling; and Check one particular modelling area that was judged to be important, based on this review, with a limited...

2012:17 Technical Note, Corrosion of copper canister
deposition holes and tunnels in the Forsmark repository will be very slow. Thus, it might take some few hundred years up to thousand years before the deposition holes are filled with ground water and it might ... saturated and pressurized. The copper canisters will therefore meet to two completely different environments; an initial period of several hundreds of years when copper is exposed to gaseous corrosion and then...

2012:15 Technical Note, A review of the mechanical integrity of the canister
of the canister. The review is focused on the copper canister and the nodular cast iron insert. Review results show that a number of loads and loading scenarios for the copper canister has not been analysed ... analysed by SKB. The importance of sufficient creep ductility of the copper material and sufficient ductility and fracture toughness of the nodular cast iron material is pointed out in the review. A sensitivity...

2012:13 Technical Note, A review of the creep ductility of copper for nuclear waste canister application
Alternatively SKB needs to find an explanation to the effect of phosphorus on the creep ductility and that it ensures the absence of creep brittleness in OFP copper. It is interesting to note that SKB ... material tested in cracked specimens. Perhaps it is possible to more systematically study formation and growth of intergranular cracks in specimens of OFP copper with cracks Kjell Pettersson SSM English...

2012:11 Issues in the corrosion of copper in a Swedish high level nuclear waste repository
project was to increase knowledge in the area of copper corrosion in the planned repository environment and obtain information on how copper corrosion evolves during the assessment period of 100 000 years. The ... thermodynamics code called GEMS. Based on the results, the following sulphide species (S2-, HS-, H2S, HS22-, and S22-) are predicted to be present in sufficient concentrations to cause copper corrosion in the repository...
