  2. 1. Maturation of Clay Seals in Deep Bore Holes for Disposal of Radioactive waste : Theory and Experiments

    Author : Ting Yang; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-level radioactive waste; HLW; very deep borehole; VDH; disposal; saturation degree; water transport; maturation; model; shear strength; hydraulic conductivity; swelling pressure; homogenization; Geoteknik; Soil Mechanics;

    Abstract : KBS-3 and very deep borehole (VDH) concepts are two major types of long-term geologicaldisposal methods for high-level radioactive waste (HLW) isolating from the biosphere. TheKBS-3V concept for isolating the HLW at the depth of 400-500 m, is the officially proposedoption in Sweden and has been the subject of considerable research in the past few decades,while the VDH concept was considered as an option in the 1950s but later became discouragedbecause of insufficient experience in drilling technology.

  5. 3. Remediation of materials with mixed contaminants : treatability, technology and final disposal

    Author : Kristin Elgh-Dalgren; Patrick van Hees; Bert Allard; Dan Berggren Kleja; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioremediation; Microtox®; mixed contaminants; re-cycling; soil remediation; soil washing.; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

    Abstract : Contaminated soils are a large issue worldwide and much effort has been made to find efficient remediation methods. At many contaminated sites, mixtures of dif­ferent contaminants with different properties are present, which may lead to addi­tional problems, and thus additional costs, during the remediation process.
