FAST: Generation-IV nuclear reactors with a fast neutron spectrum

We launched the project in 2002 and our current goals are
  • to study neutronics, thermal hydraulics and fuel behaviour of advanced fast-spectrum nuclear reactors using modern computational tools (TRACE/PARCS/FRED, Eranos/EQL3D, Serpent 2, OpenFOAM);
  • to evaluate safety of fast reactors considered for construction in Europe (in particular, ASTRID SFR);
  • to analyse innovative design solutions for Generation-IV Molten Salt Reactor;
  • to represent Switzerland internationally (GIF, IAEA, OECD, EURATOM);
  • to educate young researchers and students (in particular, via the ETHZ/EPFL Master of Science in Nuclear Engineering and EPFL PhD programs).

Hyemin Kim successfully passed the MS exam. The topic of her MS study was "Static and transient analysis of Molten Salt Reactor Experiment using SERPENT-2/TRACE/PARCS codes". The experiment, completed 50 years ago, was partly re-analyzed with the modern codes to improve our understanding of the liquid-fuel reactor physics and to validate the computational tools to be used in design and safety demonstration of the future MSRs.

Jongsoo Choe successfully passed the MS exam. The topic of his MS study was "Empirical Decay Heat Correlations and Fission Products Behavior in MSRs". Molten Salt Reactors were simulated using Serpent and EQL0D to correlate decay heat power not only with reactor operation time and time after reactor shut-down, but also with efficiency of the on-line fission gas removal system. The results were compared with MSBR simulations from ORNL reports.

Benoit Soubelet successfully passed the MS exam. The topic of his MS study was "Time efficient fluid dynamics analysis of sodium fast reactor wire wrapped rod bundles". OpenFOAM, an open-source 3D CFD code, was applied for modeling of single and two-phase (air-water) flow in a hexagonal wire-wrapped bundle. The obtained results were benchmarked with respect to TRACE, a state-of-the-art 1D thermal-hydraulics code.
