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

We launched the project in 2002 and our current goals are:

  • to study neutronics and nucleonics, 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 Sodium-cooled Fast Reactor;

  • to analyse innovative design solutions for Generation-IV Molten Salt Reactor;

  • to represent Switzerland internationally at 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.

On September 14, 2016 the NES colloquium "Molten Salt Reactor: sustainable and safe reactor for the future?" was given by Dr. Jiri Krepel. The colloquium offered a brief history of the Molten Salt Reactor, addressed its advantages, disadvantages and open issues, and presented the related international research and activities at PSI. Specific attention was brought to the inter-laboratory effort initiated within the Nuclear Energy and Safety Division during the past two years. The slides are available for download (4MB).

On August 30 Jiadong Bao successfully passed the MS exam. The topic of his MS study was "Development of the model for the multiphysics analysis of Molten Salt Reactor Experiment using GeN-Foam code". The experiment, completed 50 years ago, was partly re-analyzed with the open source multi-physics code 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.

The Expert and Policy Group meetings of the Generation-IV International Forum (GIF) were held on April 25-28, 2016 in Paris, France at the OECD Conference Centre. We represented Switzerland at these meetings. The GIF Policy Group members unanimously voted to accept Australia’s bid to join the GIF and thus become the 14th member of the forum.
