2011:31 Allocation of Decommissioning and Waste Liabilities
A crucial task for the present generations is to ensure that environmental liabilities are identified sufficiently well so that it may be possible to accumulate the corresponding necessary financial assets ... assets in the Swedish Nuclear Waste Fund. Adequate funding will provide forthcoming generation’s with the financial means to decommission and dismantle older nuclear facilities that are part of the Swedish...

2012:13 Technical Note, A review of the creep ductility of copper for nuclear waste canister application
large body of experiments only serves to prove that the creep ductility is sufficient for much shorter time spans than the intended storage times. There is a clear need for a credible theory of creep brittleness ... brittleness of OFP copper which will permit extrapolations to long term storage. The theory presented by SKB does not in its present state permit credible extrapolations. Alternatively SKB needs to find...

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...

2014:48 Technical Note, Independent assessment of groundwater sulphide content in the long-te
sulphide content is a key factor in the determination of canister lifetimes because of its role in corrosion of copper. SKB has based the canister lifetime analysis on a distribution of measured sulphide ... expert judgement in the selection of samples that are regarded as representative. The objective of this report is to make an assessment of the validity of SKB’s approach. Sulphide in groundwater derives...

1997:05 SKI SITE-94
deep geological disposal of spent nuclear fuel and high-level radioactive waste is now in the early stages of the site selection process, with feasibility studies underway in 5 to 10 municipalities. According ... selection of two sites for surface-based investigations by around the year 1998, and submission of a licence application for detailed underground investigations and for commencement of construction of a deep...

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...

2012:03 The IAEA Integrated Regulatory Review Service Mission to Sweden in February 2012
review of the Author-ity and its areas of supervision, an ‘IRRS’ (Integrated Regulatory Review Service) carried out by the International Atomic Energy Agency (IAEA). On February 25, 2009, SSM made a formal ... for an IRRS in Sweden. The time period for the IRRS mission was later agreed to be 6–17 February, 2012. This report summarises the project’s progress immediately prior to the IRRS mission in February 2012...

2016:16 Technical Note, Possible influence from stray currents from high voltage DC power transmission on copper canisters
Phase Introduction As part of the Swedish Radiation Safety Authority’s (SSM) review of the Swedish Nuclear Fuel and Waste management company (SKB) license application for a final storage for spent nuclear ... information regarding the effect of stray currents from high voltage cables on copper corrosion (SSM 2012). SKB therefore has performed an extended study of the effects of high voltage DC power transmission...

2012:34 Technical Note, Review of FEP Handling in the SR-Site Safety Assessment: Initial Review Phase
applications for licences to construct a spent nuclear fuel encapsulation facility in Oskarshamn and a repository for final disposal of the encapsulated fuel in Forsmark. SKB’s applications are currently ... Swedish Radiation Safety Authority, SSM, and the Land and Environmental Court in Nacka. SSM is undertaking a phased review of the safety assessment. Currently, an Initial Review Phase is being undertaken...

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...
