• 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 ... 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 called...

• 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...

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

  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 ... states of the structural iron in montmorillonite, the dominant mineral in bentonite, have been shown to be sensitive to such irradiation in experimental studies using suspended bentonite. The change of the...

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

  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 ... is located in Oskarshamn, Sweden. The Clab facility operates several linked underground storage pools which are expected to have a storage capacity of 11,000 tons. Figure 1 is a photo of one of the underground...

• 2011:34 Evolution of hydrogen by copper in ultrapure water without dissolved oxygen

  difficulties of repeating Hultqvist and co-workers work are considerable and were initially underestimated. The main challenge was to obtain satisfactory tightness of all connectors involved in the experimental ... problems with leakage resulted in that the research program originally planned for in this project had to be reduced considerable. Nevertheless, experimental work conducted in this project has in principle...

• 2012:61 Geochemical Constraints on Buffer Pore Water Evolution and Implications for Erosion

  Mineralogical data from the Forsmark Site show that smectite and calcite occur at all depths in Forsmark fractures, with no evidence for removal/dissolution by previous glacial episodes.  This natural analogue ... groundwaters are in equilibrium (steady-state) with montmorillonite and saponite and these minerals may control pH, PCO2, SiO2(aq) and Na/Ca in groundwaters (and any future intruding glacial meltwaters) in the near-field...

• 2014:20 An evaluation of high-temperature creep of zirconium alloys: data versus models

  In this report Dr Massih presents correlations for creep in different phases of zirconium alloys and also presents a general solution to the difficulty of accurately describing the material properties ... properties in phase transition for several zirconium alloys. Based upon superplasticity relations, models are adapted to fit with experimental data for materials in transition regions. The creep models are developed...
