  • 2012:12 APRI-7 Accident Phenomena of Risk Importance. En lägesrapport om forskningen inom området svåra haverier under åren 2009-2011

    Kunskap om de fenomen som kan uppträda vid svåra haverier i en kärnkraftanläggning är en viktig förutsättning för att kunna förutse anläggningens beteende, för att kunna utforma rutiner och instruktioner för haverihantering, för beredskapsplaneringen samt för att få god kvalitet på haverianalyser och riskstudier. Sedan...

  • 2012:26 Technical Note, Initial review of chemical and erosional processes within the buffer and backfill - Chemical erosion processes

    The SR-Site documentation relevant to this review topic was found to be of sufficiently high quality overall to justify further consideration in the Main Review Phase of SSM’s PCS (Post-closure safety) project. Several specific topics for which complementary information and clarifications should be requested from SKB were also identified (Appendix 2). Specific review topics for consideration...

  • 2012:53 Technical Note, Review of Engineering Geology and Rock Engineering aspects of the operation and closure of a KBS-3 repository at the Forsmark site – Initial Review Phase

    SRK Consulting (UK) Limited (SRK) has reviewed the Engineering Geology and Rock Engineering aspects of the operation and closure of a KBS-3 repository at the Forsmark site in Sweden. The review assignment is part of a Swedish Radiation Safety Authority (SSM) Initial Review Phase. The review was carried out by David Saiang (PhD) on behalf of SRK. Therefore some of the views expressed in the...

  • 2012:48 Technical Note, Use of Solubility Limits in the SR-Site Safety Assessment

    In a radioactive waste disposal environment, in some potential situations (scenarios) a disposed canister containing spent fuel may be breached and the fuel may come into contact with groundwater. The concentration of a radioactive element such as uranium may rise to a level where the solution is saturated. No more of the radioactive element may dissolve and a precipitated solid may be formed.

  • 2012:24 Technical Note, Initial Review of SR-Site Main Report

    The Swedish Radiation Safety Authority (SSM) is reviewing a license application, which has been submitted by Svensk Kärnbränslehantering AB (SKB), for a repository for the final disposal of spent nuclear fuel.  SKB’s Application includes an assessment of the long-term safety of the proposed repository.  The assessment is known as SR-Site. This technical note records the findings...

  • 2012:02 Evaluation of activity build-up experiments

    This project aims to understand how the water chemistry affects the activity build-up on surfaces in different systems in Swedish nuclear power plants, which in turn provides information on conditions required to reduce the radiation exposure to power plant staff. The study was done to obtain knowledge about water chemistry conditions preferred to minimize the activity build-up. A number of...

  • 2012:68 Assessment of cost for dismantling of Ringhals 2 PWR

    The Financing Act stipulates that future expenses for dismantling of Nuclear Power Plants (NPP) shall be financed from segregated funds that are supervised by the Swedish Nuclear Waste Fund (SNWF). Transparency of and confidence in the process to ensure collection of sufficient funds is fundamental for the acceptance and sustainability of the Swedish model for estimating environmental...

  • 2012:55 Technical Note, Review of SKB’s Radionuclide Transport Methodology

    As part of SSM’s Initial Review Phase of SKB’s SR-Site safety assessment of the final disposal of spent nuclear fuel at the Forsmark site, Quintessa has been requested by SSM to consider whether SKB’s methodology to abstract FEPs (features, events, processes), as well as site information and other data, into assessment models for radionuclide transport is appropriate and sufficient for its...

  • 2012:51 Technical Note, Rock Mechanics related to long-term repository and site evolution

    In general, SKB demonstrates that they have accumulated a significant set of hydraulic, mechanical and thermal data that is essential for constructing a deep geological repository. The method of data acquisition is robust using the internationally- recognized and suggested methods. The methodology of safety assessment is firmly established by applying the state-of-the-art technology and...

  • 2012:45 Beräkning av merkostnader 2012 för avveckling och rivning av de svenska kärnkraftverken och omhändertagande av restprodukter

    I föreliggande rapport presenteras Strålsäkerhetsmyndighetens beräkningar av statens förväntade framtida kostnader, de så kallade merkostnaderna. Beräkningen görs i enlighet med lagen (2006:647) om finansiella åtgärder för hanteringen av restprodukter från kärnteknisk verksamhet (finansieringslagen) och avser de förväntade...
