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. Development of an integrated neutronic/thermal-hydraulic tool for estimating fluctuations in PWRs
Abstract : Monitoring and diagnostics of a reactor core at a given state is very important for detecting potential problems and anomalies at an early stage. Several methods exist for these purposes, but the majority of them require a disruption of the plant operation, e.g. by shut-down or by perturbation of the system. READ MORE

3. Investigation of a discrete ordinates method for neutron noise simulations in the frequency domain
Abstract : During normal operations of a nuclear reactor, neutron flux measurements show small fluctuations around mean values, the so-called neutron noise. These fluctuations may be driven by a variety of perturbations, e.g., mechanical vibrations of core components. READ MORE

4. The Diversity and Unity of Reactor Noise Theory
Abstract : The study of reactor noise theory concerns questions about cause and effect relationships, and the utilisation of random noise in nuclear reactor systems. The diversity of reactor noise theory arises from the variety of noise sources, the various mathematical treatments applied and the various practical purposes. READ MORE

5. Local structure in disordered materials studied by neutron scattering and RMC modelling
Abstract : Different disordered materials are becoming more and more important in various technological applications. There is a need to improve our detailed understanding of the local structure of such materials and how the atomic structure is related to macroscopic physical properties. READ MORE
