2012:18 Technical Note, SR-Site Independent Modelling of Engineered Barrier Evolution and Coupled THMC: Contribution to the Initial Review Phase
the modelling of the Engineered Barrier System (EBS) evolution, which includes coupled thermal, hydraulic, mechanical and chemical (THMC) processes. Additionally, the role of the EBS in the wider safety ... including its treatment in scenarios and its representation in conceptual models since this provided the motivation for the modelling work that was undertaken by SKB. The scope of the work described here...

2012:48 Technical Note, Use of Solubility Limits in the SR-Site Safety Assessment
In a radioactive waste disposal environment, in some potential situations (scenarios) a disposed canister containing spent fuel may be breached and the fuel may come into contact with groundwater. The ... concentration of a radioactive element such as uranium may rise to a level where the solution is saturated. No more of the radioactive element may dissolve and a precipitated solid may be formed. In this situation...

2013:37 Technical Note, Rock Mechanics – Evolution of fracture transmissivity within different scenarios in SR-Site – Main Review Phase
The current review assignment consists of a literature review and independent modeling for assessing the importance of fracture transmissivity change especially driven by shear loading due to SKB’s thermal ... repository at Forsmark. In the first part of the report, SKB’s laboratory experiments on shear fracture dilation and extensive literature review on shear fracture dilation in-situ and in laboratory under moderate...

2022:08 Geophysical surveys on sub marine land- and rock slides and on alpine glaciers
future climate evolution and the impact it might have on a repository for radioactive waste is important when assessing the long-term safety. In a project funded by SSM (Holmlund et al. 2016), bathymetric ... as terrestrial data from a glacial morphological mapping campaign. A broad range of landforms could be observed in these data and the overall glacial morphology pointed towards a powerful glacial impact...

2013:36 Technical Note, Review and assessment of aspects of the Qeq concept – Main Review Phase
transport of dissolved constituents in the near field at the Forsmark site, in particular the Qeq abstraction for diffusive transport. SKB uses the Qeq parameter to scale concentration gradients in order ... order to estimate dissolved-species fluxes from the far-field environment to the canister surface and from a canister breach to the far field. To accomplish the review assignment, we (i) reviewed relevant...

2014:34 Technical Note, Modelling Comparison of Simple Reference Biosphere Models with LDF Models – Main Review Phase
development of simple reference biosphere models as a means of exploring the Landscape Dose Factor (LDF) approach adopted by SKB in the SR-Site safety assessment for the proposed final disposal of spent nuclear ... fuel at the Forsmark site. The models are developed and described in a systematic manner, based on international guidance reflected in the International Atomic Energy Agency’s BIOMASS approach. The context...

2012:32 Technical Note, Groundwater Chemistry in SKB’s Safety Assessment SR-Site: Initial Review
This preliminary review of SR-Site is focused specifically on the treatment of groundwater chemistry in the description of the Forsmark site and in the long-term safety of a deep geological repository ... compositions of groundwaters have contributed to a site descriptive model (SDM) for Forsmark. In that SDM, groundwater chemistry is interpreted for several purposes. The main outputs are the description of present-day...
