  2. 6. 14C Produced by Nuclear Power Reactors - Generation and Characterization of Gaseous, Liquid and Solid Waste

    Author : Åsa Magnusson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; waste disposal; spent ion-exchange resins; mass balance assessment; Nuclear physics; environmental impact; Fysicumarkivet A:2007:Magnusson; nuclear power plant; Kärnfysik; Carbon-14;

    Abstract : This thesis presents the results from studies on carbon-14 produced by nuclear power reactors. Radioactive 14C enters the carbon cycle and can be taken up by humans, where it will constitute a potential health hazard. READ MORE

  4. 7. Borehole sealing with expandable buffer clays in HLW disposal : Lab-scale performance

    Author : Ting Yang; Jörn Kasbohm; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Two basically different multibarrier concepts for high-level radioactive waste (HLW) are the often cited KBS-3 V/H concepts, for isolating nuclear waste at 400-600 m depth and Very Deep Boreholes concepts (VDH) for placement at 2000-4000 m depth. Both make use of expandable clay as isolating medium of canisters with HLW and as backfill material in shafts and tunnels in repositories for safe disposal of such waste. READ MORE

  5. 8. Performance of Clay Liners in Near-Surface Repositories in Desert Climate

    Author : Laith Al-Taie; Frank Wagner; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Wars in Iraq (1991 and 2003) generated various types of hazardous waste (HW) in the form of soil contaminated by depleted uranium (DU). Other HW emanated from destroyed army vehicles and remnants of Iraqi nuclear facilities holding various types and amounts of chemical and radioactive material. READ MORE

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

    Author : Göran Källvenius; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

  7. 10. The bentonite barrier : microstructural aspects on colloid filtration and radiation effects on bentonite colloid stability

    Author : Michael Holmboe; Mats Jonsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry;

    Abstract : In many countries a multi-barrier concept in a deep geological repository is planned for final disposal of nuclear waste. Many of these different concepts, for example the Swedish KBS-3 model, include an engineered barrier consisting of compacted bentonite. READ MORE
