1. Ash chemistry and fuel design focusing on combustion of phosphorus-rich biomass
Abstract : Biomass is increasingly used as a feedstock in global energy production. This may present operational challenges in energy conversion processes which are related to the inorganic content of these biomasses. As a larger variety of biomass is used the need for a basic understanding of ash transformation reactions becomes increasingly important. READ MORE

2. Studies of Nuclear Fuel Performance Using On-site Gamma-ray Spectroscopy and In-pile Measurements
Abstract : Presently there is a clear trend of increasing demands on in-pile performance of nuclear fuel. Higher target burnups, part length rods and various fuel additives are some examples of this trend. READ MORE

3. Development of Encapsulated UN-UO₂ Accident Tolerant Fuel
Abstract : Accident tolerant fuels (ATFs) are designed to endure a severe accident in the reactor core longer than the standard UO2-Zr alloy systems used in light water reactors (LWRs). Composite fuels such as UN-UO2 are being considered as an ATF concept to address the lower oxidation resistance of the UN fuel from a safety perspective for use in LWRs, whilst improving the in-reactor behaviour of the UO2 fuel.

4. New insights into lubricated tribological contacts
Abstract : The emissions of carbon dioxide, CO2, must rapidly be reduced to avoid severe climate change. Tribology-related solutions can be an important part in reducing these emissions. The aim of this thesis is to improve the fundamental knowledge in two tribology-related fields, both concerning lubrication, to enable such solutions in the future. READ MORE

5. Chemical Properties of FBC Ashes
Abstract : In this thesis several aspects of ash chemistry are discussed. An issue of primary concern for boiler operators is the formation of ash deposits. New biomass fuels are introduced, many of which have unfavourable ash melting behaviour due to high levels of alkali metal species and chlorine. READ MORE
