• 2026:04 3D Discrete Element Modelling of Fluid Injection Induced Fault Slip in Argillaceous Rock – Mt.Terri Fault Slip Experiment

  SSM perspectiv Bakgrund och syfte Det är ett välkänt fenomen att injektering av exempelvis saltvatten i berggrunden kan leda till en artificiell ökning av porvattentryck vilket i sin tur kan utlösa jordbävningar (Walsh och Zoback 2015, med referenser). Ökat porvattentryck på djupet kan även förekomma naturligt, till exempel till följd av de...

• 2026:05 Thermally Induced Fracture Slip in Crystalline Rock: Experimental and Numerical Studies and Safety Implications for Geological Disposal of Nuclear Wastes

  SSM perspective Bakgrund och syfte Högaktivt radioaktivt avfall, såsom använt kärnbränsle, kommer att fortsätta generera värme under en lång tid. Restvärmen resulterar i en termisk expansion av berget kring förvaret, vilket kan framkalla deformationer i spricksystemet. Närfälts-effekter kan innebära termiskt inducerad glidning längs...

• 2023:11 Study of degradation of spent fuel’s structural material and core components under long-term wet storage

  SSM perspective Background Sweden is managing the spent nuclear fuel and core components from its commercial nuclear reactors with a national strategic plan. The fuel and core components are initially stored at the reactor site. After an on-site storage period to comply with transportation limits on decay heat and radiation, these materials are shipped to the Clab (Central Interim Storage...

• 2023:14 Effect of gamma-irradiation on the redox states of the structural iron in bentonite clay

  SSM perspective Background Bentonite clay is used as buffer and backfill material which form engineered barrier in the spent fuel repository. The buffer material surrounding the copper canister will be exposed to gamma and neutron radiations, especially during the first few hundred years after closure of the repository. The redox states of the structural iron in montmorillonite, the dominant...

• 2017:18 FEM analysis of the mechanical integrity for the canister intended for storage of spent nuclear fuel with regard to copper creep ductility

  Background For final storage of spent nuclear fuel it is suggested by the Swedish nuclear fuel and waste management company (SKB) to emplace the nuclear fuel into copper canisters which are surrounded by bentonite clay at approximately 500 meters’ depth into granitic rock. After emplacement of the canisters Bentonite swelling due to water saturation and hydrostatic pressure build up the...

• 2017:02 Slow strain rate testing of copper in sulfide rich chloride containing deoxygenated water at 90 °C

  Background Stress corrosion cracking (SCC) can occur in materials from the combined influence of tensile stress and a corrosive environment. It has previously been shown in the literature, that copper can be sensitive to SCC in the presence of sulfide containing water. Since both tensile...

• 2010:32 Fingerprints of zones in boreholes An approach to identify the characteristics of structures

  This report concerns a study which was initially conducted for the Swedish Nuclear Power Inspectorate (SKI), which is now merged into the Swedish Radiation Safety Authority (SSM). The conclusions and viewpoints presented in the report are those of the authors and do not necessarily coincide with those of the SSM. The Swedish Nuclear Fuel and Waste Management Co (SKB) has published Site...

• 2010:40 Rock-block characterization on regional to local scales for two SKB sites in Forsmark – Uppland and Laxemar – eastern Småland, south-eastern Sweden

  To get an overall impression of the general structural setting of a landscape, a remote study of bedrock structures should include studies of the geomorphology at various scales. Thematic maps improve the general understanding of an area. Digital elevation data in 500m, 50m and 10m grids were used for rock-block interpretations at regional, semi-regional and local scales of areas around the...

• 2010:38 The feasibility of Backfilling a Repository of Spent Fuel: An Assessment of Recent Developments by SKB

  In the Review Statement and Evaluation of SKB’s RD & D programme 2007 (SKI Report 2008:48E), the former Swedish Nuclear Power Inspectorate (SKI) commented that considerable work remained to be done for knowledge of both practical management issues on backfilling and analysis of long-term backfill evolution to reach the same level as for the canister and the buffer. SKI considered that the...
