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.

At the end of January 2017 PSI hosted for the first time the meeting of GIF Molten Salt Reactor project and organized on this occasion the MSR workshop. More than 100 participants from 18 counties were listening, in the PSI auditorium, to the presentation of 7 major national projects of the GIF MSR project members and observers. The presentations are available at the GIF workshop website: https://www.gen-4.org/gif/jcms/c_82829/workshops

The EU Horizon-2020 program granted 5 million Euros to the research and innovation project coordinated by Dr. Konstantin MIKITYUK, Fast Reactors Group Leader at LRS/NES/PSI. With 19 partners and the total budget of about 10 million Euros, the ESFR-SMART project aims at enhancing further the SFR safety and, in particular, of the commercial-size European Sodium Fast Reactor developed in frame of the Generation-IV International Forum. During four years the project will produce new experimental data; test and qualify new instrumentations; perform further validation of the computational tools; select and assess new safety measures for each defence-in-depth level; strengthen and link together the networks of the European sodium facilities and of the students working on SFR technologies.

One PhD student and two MS students started at the Fast Reactors Group in February 2017. Rodrigo GONZALEZ GONZAGA DE OLIVEIRA started his PhD study on modeling of molten salt fast reactor with GeN-Foam in cooperation with Dr. C. Fiorina from EPFL. Fanny VITULLO started her MS study on impact of pebble movement on the fuel burnup in High Temperature Reactor in cooperation with Dr. J. Kalilainen (LTH) and Emeline BELTJENS started her MS study on neutronic and thermal-hydraulic analysis of the low-void SFR core using the Serpent and TRACE/PARCS codes in frame of the CEA-PSI bilateral cooperation ARDECo.

In November 2015 Switzerland joined the GIF MSR activities and the upcoming 23rd GIF MSR pSSC meeting will be hosted by Paul Scherrer Institute, the Swiss implementing agent. At this occasion an MSR workshop dedicated to the national projects of the GIF MSR partners will be held. It will include the country programs of China, EU, France, Russia, USA, and the motivation and foreseen project of Australia and Switzerland.

On October 4, 2016, the proposal for the project called "European Sodium Fast Reactor Safety Measures Assessment and Research Tools (ESFR-SMART)" was submitted in response to NFRP2 "Research on safety of fast neutron Generation-IV reactors" of Euratom Work Program 2016-2017. The consortium of the proposed project includes 19 partners from 8 countries. The project is coordinated by Dr. K. Mikityuk (PSI). The first three pages of the proposal (list of participants, table of content and abstract): download.
