1. Generation, stability and migration of montmorillonite colloids in aqueous systems
Sammanfattning : In Sweden the encapsulated nuclear waste will be surrounded by compacted bentonite in the granitic host rock. In contact with water-bearing fractures the bentonite barrier may release montmorillonite colloids that may be further transported in groundwater. LÄS MER
2. 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.

3. The impact of groundwater chemistry on the stability of bentonite colloids
Sammanfattning : I det svenska djupförvaret för kärnbränsle ska kompakterad bentonit användas som barriär mellan kopparkapslar med utbränt kärnbränsle och berget. I kontakt med vattenförande sprickor kan bentonitbarriären under vissa omständigheter avge montmorillonitkolloider. LÄS MER
4. Groundwater chemistry and recharge rate in crystalline rocks : case study from the Eritran highland
Sammanfattning : .... LÄS MER
5. Oxidative dissolution of UO2 by α-radiolysis
Sammanfattning : To prevent the spread of radiotoxic nuclides in the environment, spent nuclear fuel generated by decades of nuclear power operation must be safely stored for at least 100 000 years. The KBS-3 method is a highly developed deep geological repository concept and is the first final repository design for high-level nuclear waste to be constructed. LÄS MER
