• 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...

• 2024:19 Finansiering av en minnesinstitution efter förslutning av slutförvar för använt kärnavfall

  SSM perspektiv Bakgrund och syfte En central princip för dagens finansieringssystem för omhändertagandet av kärnämne och övrigt radioaktivt avfall som uppkommit vid drift och avveckling av kärnkraftverk är producentansvarsprincipen1. Ett finansieringssystem som grundas på en avgift per levererad kilowattimme till den s.k. Kärnavfallsfonden. I tillägg...

• 2025:02 INCLUDE: Including (local) stakeholder participation in the regulatory mission – a future challenge

  SSM perspektiv Bakgrund Det primära fokus för SSM:s kommunikation med intressenter i samband med slutförvaring av använt kärnbränsle och kärnavfall har under flera år legat på formella samrådsprocesser kring den svenska kärnkraftsindustrins forsknings- och utvecklingsprogram samt SKB:s tillståndsansökningar enligt kärntekniklagen.

• 2012:11 Issues in the corrosion of copper in a Swedish high level nuclear waste repository

  The objective with this research 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 equilibrium chemical composition of groundwater close to the canister as a function of temperature has been calculated by use of a thermodynamics code...

• 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...

• 2014:30 Modelling Approaches to C-14 in Soil-Plant Systems and in Aquatic Environments

  Substantial expertise on carbon biogeochemistry already exists in the fields of plant physiology and aquatic ecology and therefore is it beneficial to draw on this to identify the important issues. A paper describing the BIOPROTA C-14 model inter-comparisons, and plans for the forward programme was published in Radiocarbon Journal. Further studies on C-14 (including modelling, model...

• 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...
