• 2015:30 Technical Note, Rock Mechanics - Assessing the likelihood and extent of fracture growth in the KBS-3 repository at Forsmark

  This review work concerns the evaluation of the likelihood and extent of fracture growth around the deposition tunnels and holes of the planned KBS-3 repository at Forsmark. The issues of the isostatic, shear and thermal loading concerning the stability and evolution of rock fractures around the KBS-3 repository at Forsmark are addressed. Hereby, the thermal, glacial and earthquake scenarios...

• 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, glacial and earthquake loading scenarios for the KBS-3 repository at Forsmark. In the first part of the report, SKB’s laboratory experiments on shear fracture dilation and extensive...

• 2012:51 Technical Note, Rock Mechanics related to long-term repository and site evolution

  In general, SKB demonstrates that they have accumulated a significant set of hydraulic, mechanical and thermal data that is essential for constructing a deep geological repository. The method of data acquisition is robust using the internationally- recognized and suggested methods. The methodology of safety assessment is firmly established by applying the state-of-the-art technology and...

• 2012:55 Technical Note, Review of SKB’s Radionuclide Transport Methodology

  As part of SSM’s Initial Review Phase of SKB’s SR-Site safety assessment of the final disposal of spent nuclear fuel at the Forsmark site, Quintessa has been requested by SSM to consider whether SKB’s methodology to abstract FEPs (features, events, processes), as well as site information and other data, into assessment models for radionuclide transport is appropriate and sufficient for its...

• 2012:41 Technical Note, Hydrogeological conditions at the Forsmark site

  The hydrogeological site description and groundwater models employed in support of SR-Site, in many ways, represent advances in the state of the art for crystalline bedrock where groundwater moves mainly through fractures. Advanced methods are used for representing water-conducting natural features on scales from kilometres down to a meter, as well as excavated portions of the repository...

• 2012:38 Technical Note, Radiological effects on non-human biota - initial review

  The focus of this review was SKB’s assessment of radiological effects on non-human biota in SR-Site according to present regulations and guidance from SSM and it was conducted by Karolina Stark at the Department of Systems Ecology, Stockholm University. In short, the results from this review show that the completeness of the safety assessment can be questioned regarding considered...

• 2016:21 The effect of a glaciation on East Central Sweden: case studies on present glaciers and analyses of landform data

  The Swedish Radiation Safety Authority reviews and assesses applications for geological repositories for nuclear waste. When assessing the long term safety of the repositories it is important to consider possible future developments of climate and climate-related processes. Especially the next glaciation is important for the review and assessment for the long term safety of the spent nuclear...

• 2016:30 Measurement of Parameter Values for Predicting Corrosion Phenomena on Copper in Swedish HLNW Repositories

  Passivity breakdown and pitting on pure copper, the assumed material for the canisters for the isolation of high-level nuclear waste in Sweden, has been studied in simulated, sulphide- and chloride containing granitic rock groundwater and the data are interpreted in terms of the Point Defect Model (PDM). The results indicated that a sulphide barrier layer forms on the copper surface, and that...
