1. Developments and application of neutron noise diagnostics of sodium cooled fast reactors
Abstract : The Sodium cooled Fast Reactor (SFR) is one of the six reactor types selected by the Generation-IV international forum (GIF), and the building of an industrial prototype is planned in France. The safety standard of the future SFR has to be equivalent to the EPR's. READ MORE

2. Neutron Irradiation Techniques
Abstract : The He-3 “crisis” has become a fact in the last decade and large scale neutron detectors based on He-3 technologies have become unaffordable. This new He-3 reality has resulted in a major effort worldwide to develop replacement neutron-detector technologies. READ MORE

3. Control Rod Homogenization in Heterogeneous Sodium-Cooled Fast Reactors
Abstract : The sodium-cooled fast reactor is one of the candidates for a sustainable nuclearreactor system. In particular, the French ASTRID project employs an axiallyheterogeneous design, proposed in the so-called CFV (low sodium effect) core, toenhance the inherent safety features of the reactor.

4. Fast-Neutron Tomography using a Mobile Neutron Generator for Assessment of Steam-Water Distributions in Two-Phase Flows
Abstract : This thesis describes the measurement technique of fast-neutron tomography for assessing spatial distributions of steam and water in two-phase flows. This so-called void distribution is of importance both for safe operation and for efficient use of the fuel in light water reactors, which compose the majority of the world’s commercial nuclear reactors.

5. Advanced fuels for thermal spectrum reactors
Abstract : The advanced fuels investigated in this thesis comprise fuels non− conventional in their design/form (TRISO), their composition (high content of plutonium and minor actinides) or their use in a reactor type, in which they have not been used before (e.g. nitride fuel in BWR). READ MORE
