1. The Underground as a Storage Facility. Modelling of Nuclear Waste Repositories and Aquifer Thermal Energy Stores
Sammanfattning : The underground is a vast region, which is, too a large extent, unused by man. It has a large potential as a storage facility due to its vastness and availability. This thesis, which consists of eleven papers and reports, deals with nuclear waste repositories in solid rock and with aquifer thermal energy storage systems. LÄS MER
2. Chlorite: Geochemical properties, Dissolution kinetcis and Ni(II) sorption
Sammanfattning : In Sweden, among other countries, a deep multi-barrier geological repository, KBS-3, is planned for the burial of nuclear waste. One of the barriers is identified as the grantic bedrock itself and in this environment chlorite is present at surfaces in fracture zones. LÄS MER
3. Redox Reactions of Uranium-Based Materials in Aqueous Systems and Under UHV Conditions. : Two models mimicking radiation-induced oxidation of spent nuclear fuel
Sammanfattning : The demand for clean electricity is a primary concern in Europe. Nuclear power isconsidered as a greenhouse gas-free technology for generation of electricity. However,compared to other energy sources, it generates a highly toxic waste.In Sweden, the long-term solution for the waste disposal issue is called the KBS-3 method. LÄS MER
4. Borehole sealing with expandable buffer clays in HLW disposal : Lab-scale performance
Sammanfattning : 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. LÄS MER
5. The Influence of Hydrogen on the Radiolytic Oxidation of UO2
Sammanfattning : Spent nuclear fuel from the nuclear fuel cycle contains radiotoxic nuclides which must be safely stored for over 100 000 years. The Swedish final repository concept, KBS-3, is based on engineered and geological barriers that prevent the nuclear fuel from coming in contact with groundwater, which is the most credible vector to transport the radionuclides into the biosphere.
