1. Towards Efficient Monte Carlo Calculations in Reactor Physics : Criticality, Kinetics and Burnup Problems
Abstract : This thesis presents a compilation of work focused on Monte Carlo crit-icality, kinetics and burnup calculations in reactor physics. Performing suchcalculations usually comes at a high computing cost. Therefore, the main mo-tivation behind the presented work is lowering the computing cost of MonteCarlo calculations. 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. Neutronic and burnup studies of accelerator-driven systems dedicated to nuclear waste transmutation
Abstract : Partitioning and transmutation of plutonium, americium, and curium is inevitable if the radiotoxic inventory of spent nuclear fuel is to be reduced by more than a factor of 100. But, admixing minor actinides into the fuel severely degrades system safety parameters, particularly coolant void reactivity, Doppler effect, and (effective) delayed neutron fractions. READ MORE

4. Gamma radiation techniques for non-destructive post-irradiation examination of nuclear fuel : Predicting performance and optimizing instrument design
Abstract : Collimated gamma-based techniques are widely used to study nuclear fuel, especially for non-destructive post-irradiation examination (PIE). Examples of such techniques include gamma emission tomography (GET) and gamma transmission densitometry (GTD). READ MORE

5. Modeling of Fission Product Behavior in Fast Reactors
Abstract : Den natriumkylda snabbreaktorn är en av kandidaterna till nästa generationens kärnenergisystem. De extrema förhållanden som kärnbränslet utsätts för i en sådan rektor kan leda till säregna konsekvenser. Till dessa hör formationen av så kallad JOG (franska för Joint Oxyde-Gaine = bränsle-kapsel-fog). READ MORE
