Current research in Nuclear Engineering
The research activity includes studies of severe accident phenomena in nuclear power plants; advanced multi-physics and multi-scale simulation methods for coupled neutron-kinetic and thermal-hydraulic analysis of transients and accidents in nuclear reactors; experiments and analyses to support safety design of advanced nuclear energy systems, and basic research in boiling heat transfer.
Research on reactor physics focuses on the transmutation of nuclear waste, mainly in design and safety analysis of fourth-generation lead-cooled reactors. In our uranium laboratory, we are developing advanced nitride fuels with high thermal conductivity. We also use multi-scale modeling to study nuclear fuel characteristics during operation, as well as the radiation damage in different model steel.
Reactor Technology includes engineering principles for design, analysis and understanding of processes and systems in nuclear power plants with or in connection with thermal hydraulics, reactor physics and structural integrity. The research is largely focused on two-phase flows with applications to nuclear fuel. Both experimental and theoretical research is performed within the group. The experimental part mainly focuses on heat transfer in the reactor core, while the theoretical part covers the methodology and modeling of nuclear systems from micro-scale to system-level with particular focus on the connection between the reactor physics, structural dynamics and thermo-hydraulic processes.
