• 2018:08 Calculated radiological consequences of applying European clearance levels to scrap metal from the decommissioning of Swedish nuclear facilities

  Background Many practices involving radioactive substances generate materials with potential or known radioactive contamination. Clearance of materials means a decision that such materials can be released from regulatory control and used or disposed of without restrictions from a radiation protection point of view. According to regulations issued by the SSM, such decisions must be based on...

• 2010:41 Rock-block configuration in Uppland and the Ålands-hav basin, the regional surroundings of the SKB site in Forsmark, Sea and land areas, eastern Sweden

  This report concerns a study which was initially conducted for the Swedish Nuclear Power Inspectorate (SKI), which is now merged into the Swedish Radiation Safety Authority (SSM). The conclusions and viewpoints presented in the report are those of the authors and do not necessarily coincide with those of the SSM. The topography in Uppland is more broken in the sea area east and northeast of...

• 2011:26 The influence of temperature and fluid pressure on the fracture network evolution around deposition holes of a KBS-3V concept at Forsmark, Sweden

  In preparation for the review of SKB’s license application for disposal of spent nuclear fuel, SSM is conducting studies to evaluate the performance of the multi-barrier principle on which the KBS-3 concept is based. Copper canisters containing the spent nuclear fuel are placed into granitic bedrock at about 500 m depth and embedded in clay. Thus, the rock, the clay and the copper canister...

• 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...

• 2014:52 Beständiga förändringar av säkerhetskulturen

  Projektet har genomförts dels som en litteraturstudie och dels som en intervjuserie vid svenska kärnkraftverk. Litteraturstudien resulterade i en beskrivning av viktiga komponenter inom området säkerhetskultur, faktorer som anses möjliggöra eller förhindra att en god säkerhetskultur uppnås samt metoder och arbetssätt för att utveckla och förbättra...

• 2013:27 Numerical simulations of headed anchors break in reinforced and non-reinforced concrete structures

  The design codes for anchorage of equipment in concrete structures have been developed since the time the Swedish power plants were designed. Furthermore, the design basis has been updated and in some cases new mechanical loads have been added. As a consequence, it can be difficult for some anchorages to meet the requirements of today. In the design of anchorage equipment the beneficial effect...

• 2013:32 Upparbetning av utbränt kärnbränsle - En studie med fokus på exportkontroll

  Rapporten beskriver principerna för upparbetning samt egenskaperna hos utbränt kärnbränsle där sammansättningen hos det i reaktorn bildade plutoniumet är av avgörande betydelse för kärnvapenframställning till skillnad från civil upparbetning. Rapporten går igenom ett antal upparbetningsmetoder, både äldre metoder samt nya,...

• 2010:39 Beskrivning av Eurokoder för betongkonstruktioner

  Eurokoder, som är gemensamma europeiska standarder för utformning och dimensionering av bärande konstruktioner till byggnader och anläggningar, utarbetas av den Europeiska Standardiseringskommittén (CEN) och ges i Sverige ut av det svenska institutet för standarder (SIS). Sverige, liksom de andra CEN-medlemsländerna, är i färd med att ersätta sina...

• 2007:02e Radiation Environment in Sweden, summary

  The radiation environment to which the population of Sweden is exposed is dominated by medical investigations and background radiation from the ground and building materials in our houses. That is the conclusion of the first general Swedish summary of environmental monitoring data and dose calculations within the field of radiation. The report shows that people’s behaviour in the form of...
