  • 2017:30 SSM’s external experts’ review of SKB’s safety assessment SR-PSU – consequence analysis

    Background The Swedish Radiation Safety Authority (SSM) received an application for the expansion of SKB's final repository for low and intermediate level waste at Forsmark (SFR) on the 19 December 2014. SSM is tasked with the review of the application and will issue a statement to the government who will decide on the matter. An important part of the application is SKB’s assessment of...

  • 2015:25 Design Guide for Nuclear Civil Structures (DNB)

    The Swedish Radiation Safety Authority (SSM) and the Swedish licensees have previously in a jointly funded research project developed a design guide for civil structures at Swedish nuclear facilities to be based on Eurocodes, DNB. The report was published in January 2014 as SSM Report 2014:06. To further improve DNB and to ensure that the fundamentals of the recommendations will be applied...

  • 2010:43 Displacement along extensive deformation zones at the two SKB sites: Forsmark and Laxemar

    The Fennoscandian shield is distinguished by that the exposed bedrock is mainly composed of Precambrian metamorphic and igneous rocks older than a billion or one and a half billion years with few easily distinguished testimonies for the younger history. Large parts of the present ground surface closely coincides with a late Precambrian denudation surface; the sub-Cambrian peneplain.

  • 2012:49 Hydrogeological characteristics of sites for low- and intermediate-level waste disposal

    The Forsmark area with its selected two sites and the Laxemar-Simpevarp area with its two sites are broadly similar in terms of lithology, rock ages, and tectonic histories. The two areas differ in terms of degree of deformation, and tectonic fabric. Some lithologic and tectonic differences are noticeable between the two sites in the Forsmark area and between the two sites in the...

  • 2017:11 Extended Common Load Model: A tool for dependent failure modelling in highly redundant structures

    Background The treatment of dependent failures is one of the most controversial subjects in reliability and risk analyses. The difficulties are specially underlined in the case of highly redundant systems, when the number of redundant components or trains exceeds four. The Common Load Model (CLM), originally defined in the 70’ies, differs from other CCF models, as it relies on a specific...

  • This is how ESS works

    The European Spallation Source, or ESS research facility, comprises a neutron source that could be described as an enormous microscope for examining molecular structures. The facility will make it possible to study materials in their smallest components and is consequently useful in materials research in diverse fields such as medicine, biology, chemistry, physics and engineering.

  • Radon

    Radon is a radioactive gas that arises naturally in bedrock when radium decays. Long-term exposure to radon gas gives an elevated risk of developing lung cancer. The Swedish Radiation Safety Authority estimates that radon in dwellings causes around 500 cases of lung cancer per year in Sweden, most commonly among smokers.
