  • 2014:10 Technical Note, Rock Mechanics - Confidence of SKB’s models for predicting the occurrence of spalling – Main Review Phase

    This review study is placed in the context of SSM’s Main Review Phase for SKB’s safety assessment SR-Site. The assignment is titled “Rock Mechanics – Confidence of SKB’s models for predicting the occurrence of spalling”. The report presents the authors’ assessment in response to the questions raised by SSM. The review concentrated on two main issues: (1) the analysis of the assumptions made...

  • 2014:44 Technical Note, Independent evaluation of the number of critical canister positions in the KBS-3 repository at Forsmark – Main Review Phase

    Independent calculations were carried out to estimate Ncrit, the number of canisters in critical positions that can be expected in the proposed repository at Forsmark, based on statistical simulations of SKB's geological discrete-fracture network (Geo-DFN) models, and taking into account SKB's full-perimeter criterion (FPC) and extended full-perimeter criterion (EFPC) to screen out...

  • 2012:03 The IAEA Integrated Regulatory Review Service Mission to Sweden in February 2012

    The Swedish Government decided on January 22, 2009 to mandate the Swedish Radiation Safety Authority, SSM, to apply for an international 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 request to the IAEA for an IRRS in Sweden. The time...

  • Slutförvarets utveckling

    Strålsäkerhetsmyndigheten och myndighetens föregångare har under flera decennnier följt projektet att ta fram en plats och metod för ett slutförvar för använt kärnbränsle. På mitten av 1970-talet inledde kärnkraftsindustrin de första geologiska studierna för att kartlägga lämpliga platser i Sverige för slutförvaring...

  • 2012:18 Technical Note, SR-Site Independent Modelling of Engineered Barrier Evolution and Coupled THMC: Contribution to the Initial Review Phase

    This review has focussed mainly on the modelling of the Engineered Barrier System (EBS) evolution, which includes coupled thermal, hydraulic, mechanical and chemical (THMC) processes. Additionally, the role of the EBS in the wider safety case was reviewed, including its treatment in scenarios and its representation in conceptual models since this provided the motivation for the modelling work...

  • 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...

  • 2012:08 Deterministic Assessment of Future Costs for Dismantling (FA)

    In this study a model for advanced deterministic cost calculation has been used to find a parametric value on the cost for dismantling of the FA-facility. The study gives good description of good practise to collect, test and utilise input data in a systematic way in order to make prudent cost estimates for any particular nuclear installation The Swedish Law stipulates that future expenses...

  • 2012:15 Technical Note, A review of the mechanical integrity of the canister

    An introductory review of SR-Site has been conducted with respect to the mechanical integrity of the canister. The review is focused on the copper canister and the nodular cast iron insert. Review results show that a number of loads and loading scenarios for the copper canister has not been analysed by SKB. The importance of sufficient creep ductility of the copper material and sufficient...

  • 2012:30 Technical Note, Initial review of physical properties and processes of the buffer and backfill. THM and other physical processes

    The Swedish Radiation Safety Authority (SSM) reviews the Swedish Nuclear Fuel Company’s (SKB) applications under the Act on Nuclear Activities (SFS 1984:3) for the construction and operation of a repository for spent nuclear fuel and for an encapsulation facility. As part of the review, SSM commissions consultants to carry out work in order to obtain information on specific issues. The...
