1. Studies of Nuclear Fuel by Means of Nuclear Spectroscopic Methods
Sammanfattning : The increasing demand for characterization of nuclear fuel, both from an operator and authority point of view, motivates the development of new experimental and, preferable, non-destructive methods. In this thesis, some methods based on nuclear spectroscopic techniques are presented. LÄS MER
2. Near field immobilization of selenium oxyanions
Sammanfattning : The topic of this doctoral thesis is the potential near field immobilization of the radionuclide 79Se after intrusion of groundwater into a spent nuclear fuel canister in a repository. 79Se is a non naturally occurring long lived selenium isotope formed as a result of fission in nuclear fuel. LÄS MER
3. The effect of dissolved hydrogen on spent nuclear fuel corrosion
Sammanfattning : In case of a canister failure in a deep bedrock repository for nuclear fuel, the release of radiotoxic nuclides to the groundwater will depend on the chemical environment near the fuel surface.Due to the presence of large amounts of iron in the canister, hydrogen will be formed if the canister becomes groundwater flooded.

4. Studies of α-D-isosaccharinic Acid – Acid dissociation constant and structural conformations
Sammanfattning : .... LÄS MER
5. 14C Produced by Nuclear Power Reactors - Generation and Characterization of Gaseous, Liquid and Solid Waste
Sammanfattning : 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. LÄS MER
