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.

The March issue of Progress in Nuclear Energy publishes the second part of the paper on "The effectiveness of full actinide recycle as a nuclear waste management strategy when implemented over a limited timeframe -- Part II: Thorium fuel cycle" by B. A. Lindley (University of Cambridge), C. Fiorina (PSI), R. Gregg (NNL), F. Franceschini (Westinghouse), G. T. Parks (University of Cambridge), to which we contributed with the SFR analysis: http://dx.doi.org/10.1016/j.pnucene.2014.11.016. The first paper was devoted to the uranium fuel cycle: http://dx.doi.org/10.1016/j.pnucene.2015.07.020.

By signing the Memorandum of Understanding on November 20, 2015, Switzerland entered the Generation-IV International Forum Molten Salt Reactor (MSR) Project, joining Euratom (represented by JRC), France (represented by CEA) and Russia (represented by ROSATOM) in their collaborative efforts to develop this Generation-IV system. Switzerland will be represented by Paul Scherrer Institut and, in particular, by our group. http://www.oecd-nea.org/general/mnb/2015/december.html#4

This year the TopFuel conference on Reactor Fuel Performance was held in Zurich, Switzerland on September 13-17, 2015. The proceeding are available for download at http://www.euronuclear.org/events/topfuel/topfuel2015/transactions.htm. We contributed to two papers presented at the conference: one on fission gas trapping in the BWR fuel (A0038) and second on calculational benchmark of the sodium-cooled fast reactor fuel behaviour (A0042).

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 K. 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).
