  1. 21. Simulating Earthquake Rupture and Near-Fault Fracture Response

    Författare :Billy Fälth; Björn Lund; Roland Roberts; Harald Hökmark; Eric Dunham; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : Sweden is presently a low seismicity area where most earthquakes are small and pose no serious threat to constructions. For the long-term perspectives of safety assessments of geological repositories for spent nuclear fuel, however, the effects of large earthquakes have to be considered. LÄS MER

  3. 22. Dynamics of Spent Nuclear Fuel Dissolution : Impact of Catalysis, Matrix Composition and Time Evolution

    Författare :Annika Carolin Maier; Mats Jonsson; Christophe Jégou; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Sammanfattning : Worldwide, nuclear power produces a large portion of the electricity that we consume every day. While nuclear energy comes with certain advantages, waste originating from its use is of particular concern. LÄS MER

  4. 23. Solubility of Np(IV), Zr(IV), and Reactive Transport Modeling with Uncertainty Calculations

    Författare :Göran Källvenius; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Sweden, as some other countries, is planning to construct a repository for long-lived low and intermediate level radioactive waste. The planned repository is a concrete construction in the bedrock a few hundreds of meters below the surface. LÄS MER

  5. 24. Demokrati på delegation. Lokaliseringen av det svenska kärnavfallet

    Författare :Hanna Sofia Johansson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Kärnavfall; Demokrati; Samrådsmöten; Studieresor; Subpolitik; Svensk kärnbränslehantering AB; Gränsarbete;

    Sammanfattning : The present study concerns the siting of Swedish nuclear waste. Four cases are examined: the feasibility studies in Nyköping and Tierp (cases 1 and 2), as well as three public consultation meetings with conservationist and environmental organisations, and two study visits to nuclear facilities in Oskarshamn and Östhammar, which were held during what is called the site-investigation phase (cases 3 and 4).

  7. 25. Investigations of α-D-isosaccharinate: Fundamental Properties and Complexation

    Författare :Stefan Allard; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Waste products containing cellulose will be present in the planned underground radioactive waste repositories. It will be exposed to an alkaline environment for long periods of time. Under such conditions cellulose will degrade forming mainly isosaccharinate. LÄS MER
