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 reactors;
  • to evaluate safety of fast reactors considered for construction in Europe;
  • to study different design solutions for Generation-IV Molten Salt Reactor;
  • to represent Switzerland internationally;
  • to educate young researchers and students.

We presented five papers at International Conference on Nuclear Engineering (ICONE22) held on July 7-11, 2014 in Prague, Czech Republic: three of them were about different studies of Molten Salt Reactor, one was on designing of gas-cooled sub-critical transmuter, and one was on the OpenFOAM-based solver for simulation of reactor dynamics. The paper "Parametric lattice study of a graphite-moderated Molten Salt Reactor" presented by Boris Hombourger was selected for the best student paper award in the region Europe.
