1. 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.

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. Applications of Gamma Ray Spectroscopy of Spent Nuclear Fuel for Safeguards and Encapsulation
Sammanfattning : Nuclear energy is currently one of the world’s main sources of electricity. Closely connected to the use of nuclear energy are important issues such as the nonproliferation of fissile material that may potentially used in nuclear weapons (safeguards), and the management of the highly radioactive nuclear waste.

4. The interaction of dissolved hydrogen with α-radiolytic oxidants during nuclear fuel dissolution
Sammanfattning : Used nuclear fuel contains radiotoxic elements that will need to be kept isolated from the biosphere over a time period of 100 000 years. The KBS-3 geological storage concept aims to prevent the migration of radionuclides into the environment by different engineered barriers. 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
