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).

The 2016 January issue of Annals of Nuclear Energy publishes a paper "Static and transient analysis of a medium-sized sodium cooled fast reactor loaded with oxide, nitride, carbide and metallic fuels" by Y. Zhang and Mikityuk. We performed a preliminary safety analysis of the BN600 type sodium cooled fast reactor loaded with different types of fuels with the TRACE code, by using the safety related parameters obtained from the Serpent calculations. http://dx.doi.org/10.1016/j.anucene.2015.03.025

Jeremie Nebes successfully passed the MS exam. The topic of his MS study was "CFD simulations of sodium two-phase flows". The main goal was to evaluate the feasibility and main issues of Computational Fluid Dynamics simulations of sodium boiling in the fuel rod bundle. The work was performed in the framework of the sodium-cooled fast reactor project ASTRID in cooperation with Commissariat à l'énergie atomique et aux énergies alternatives (CEA), France.

Euratom Work Program 2016-2017 is oficially published. One action directly relates to our activities, namely, NFRP 2: Research on safety of fast neutron Generation-IV reactors. This action is aimed at development of the technical assessment of safety improvements of critical fast neutron Generation-IV systems and their supporting reactor islands, as identified by ESNII in the SET Plan Integrated Roadmap.

The Expert and Policy Group meetings of the Generation-IV International Forum (GIF) were held on October 26-30, 2015 in Saint Petersburg, Russia. We represented Switzerland at the Expert Group meeting and, in particular, presented the GIF Education and Training Task Force (see the LinkedIn group for more details).

The December issue of Nuclear Engineering and Design publishes a paper "GeN-Foam: a novel OpenFOAM(R) based multi-physics solver for 2D/3D transient analysis of nuclear reactors" by C. Fiorina, I. Clifford, M. Aufiero, K. Mikityuk, which summarizes our 2-year efforts on launching a new open-source computational engine for nuclear reactor analysis. http://dx.doi.org/10.1016/j.nucengdes.2015.05.035

SAMOFAR – Safety Assessment of the Molten Salt Fast Reactor – is a 5M€ 4-year project of the European Union research program Horizon 2020. The project consortium consists of 11 partners (CNRS, JRC, CIRTEN, IRSN, CINVESTAV, AREVA, CEA, EDF, PSI, KIT and TU Delft). The grand objective of SAMOFAR is to prove the innovative safety concepts of the Molten Salt Fast Reactor (MSFR) by advanced experimental and numerical techniques, to deliver a breakthrough in nuclear safety and optimal waste management, and to create a consortium of stakeholders to demonstrate the MSFR beyond SAMOFAR. At the end of August 2015 the kick-off meeting of the SAMOFAR project took place at Delft University of Technology with over 35 enthusiastic participants.

On 27 August 2015, Switzerland signed the Framework Agreement for International Collaboration on Research and Development of Generation IV Nuclear Energy Systems, which was extended in February 2015 for ten years, paving the way for continued collaboration among participating countries in this important area of Gen IV R&D. A signing ceremony was held at the OECD in the presence of Mr Mauro Dell'Ambrogio, Swiss State Secretary for Education, Research and Innovation, and Mr William D. Magwood, IV, NEA Director General. http://www.oecd-nea.org/general/mnb/2015/august-september.html
