• 2014:34 Technical Note, Modelling Comparison of Simple Reference Biosphere Models with LDF Models – Main Review Phase

  This Technical Note describes the development of simple reference biosphere models as a means of exploring the Landscape Dose Factor (LDF) approach adopted by SKB in the SR-Site safety assessment for the proposed final disposal of spent nuclear fuel at the Forsmark site. The models are developed and described in a systematic manner, based on international guidance reflected in the...

• 2014:24 Technical Note, Workshop on biosphere issues

  The objective of this workshop was to bring together experts in the field of radionuclide transport in the biosphere including non-human biota and dose assessment to discuss the findings of the detailed reviews performed during the main review phase and to identify any further biosphere review issues. This report describes the outcome of the workshop organized by SSM on Biosphere Issues that...

• 2014:58 Technical Note, Rock Mechanics - Assessing probability and extent of blind faults and fault-end growth around the KBS-3 repository at Forsmark – Main Review Phase

  To get a general understanding of the stability conditions of the fault and deformation zone inventory at Forsmark a reactivation potential analysis was carried out. At present-day stress conditions the deformation zones are stable and show no large deformations or detected seismicity. Any changes in stress, and in particular increase of differential stress on deformation zones, might cause...

• 2015:06 Technical Note, Feasibility of Backfilling Deposition Tunnels

  SKB has been conducting an appropriate scientific and technical programme of research and development work to investigate the many processes that may affect the choice of backfill materials, the practicali- ties of backfill emplacement, and the properties of the emplaced backfill that may affect long-term radiological safety. On the basis of this re- search and development work SKB has outlined...

• 2015:39 Technical Note, Granskning av KBS-3 avseende nukleär kriticitetssäkerhet

  SKB (Svensk Kärnbränslehantering AB) ansökte 2011 om svenska regeringens tillstånd för en föreslagen lösning, här benämnd KBS-3, för slutförvaring av använt kärnbränsle från svenska kärnkraftverk och en del mindre kvantiteter av annat fissilt material. SKB har senare tagit fram uppdaterad och tilläggsdokumentation...

• 2015:05 Technical Note, Review of uncertainty propagation and sensitivity analysis in SR-Site Main Review Phase

  The review assignment SSM2014-2060 “Review of uncertainty and sensi- tivity analysis in SR-Site” addressed three issues: Adequacy of the methods adopted by SKB for conducting sensitivity analyses Approach for use of conservative and best-estimate parameter values Propagation of uncertainty for the corrosion scenario Adequacy of the methods for sensitivity analyses: The sensitivity analyses...

• 2014:59 Technical Note, Relation between earthquake magnitude, fracture length and fracture shear displacement in the KBS-3 repository at Forsmark – Main Review Phase

  This study addresses one of several scenarios that could impair the physical integrity of the repository of spent nuclear fuel at the Forsmark site. Two sources of threat are: i) events due to thermal loading on the rock mass by the heat from canisters with spent nuclear fuel, and ii) seismic events, i.e. earthquakes, at the nearby deformation zones and zones intersecting the repository area.

• 2015:29 Technical Note, Quality Assurance in SKB’s Copper Corrosion Experiments

  I Sverige planeras slutförvaring av använt kärnbränsle. Metoden som har utvecklats kallas för KBS-3 och den bygger på tre skyddsbarriärer; kopparkapslar, bentonitlera och det svenska urberget. Det specifika syftet med den här rapporten är att få en förståelse för, och en bedömning av, SKB:s kvalitetssäkring av deras försök...

• 2015:01 Technical Note, Rock Mechanics - Thermal properties and thermal modelling of the rock in a repository of spent nuclear fuel at Forsmark – Main Review Phase

  In preparation for the review of SKB's license application for a disposal of spent nuclear fuel, SSM has conducted a series of modelling studies related to the design, construction and long-term safety of a repository at Forsmark. Several of the presented modelling works are related to the thermal evolution of the repository with time. This report extracts the results from independent SSM...

• 2015:32 Safe and responsible management of spent nuclear fuel and radioactive waste in Sweden - National Plan

  The National Plan describes the general principles (national policies), the legislative, regulatory and organizational framework (national framework) as well as the strategies (national programme and systems) that control the safe and responsible management of spent nuclear fuel and of all types of radioactive waste in Sweden, now and in the future. Flavio Lanaro (project leader), Erica...
