   Sammanfattning : It is the aim of the present study to detect the reasons for these grievances, taking as an example the new Ecological Housing Estate Flintenbreite, and to demonstrate alternative solutions. For this purpose, different concepts of assessment are employed which meet the requirements of a full life cycle analysis. LÄS MER

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

   Författare :Ting Yang; Luleå tekniska universitet; []
   Nyckelord :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;

   Sammanfattning : 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. 4. Durability of Cementitious Materials in Long-Term Contact with Water

   Författare :Arezou Babaahmadi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Nuclear electricity is considered to be an alternative energy production solution for the power industry in many countries. To ensure the sustainability of this energy solution, the disposal of the produced waste is one of the biggest issues facing nuclear electricity industries. LÄS MER
