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 developed in Europe, in particular, European Sodium Fast Reactor (ESFR) and Advanced Sodium Technological Reactor for Industrial Demonstration (ASTRID);

  • 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.

Swiss National Supercomputing Centre (CSCS) in Lugano supported our proposal for a Production Project entitled "Generation-IV European Sodium Fast Reactor: computation of the core parameters using a high-fidelity Monte Carlo code" with an allocation of 100'000 node hours over 1 year on the Cray XC40 – Manycore and 1 TB disk space. The allocation is available from October 1st, 2017 until September 30th, 2018 and will be used in frame of the Horizon-2020 ESFR-SMART project.

The Horizon-2020 ESFR-SMART project (European Sodium Fast Reactor Safety Measures Assessment and Research Tools) officially started on September 1, 2017 and ten days later 45 partners representing 19 organizations met on the European Commission premises in Brussels to kick the project off. During two days the 12 work packages of the project were presented and discussed with the focus on the first steps to make a successful start.

Emeline Beltjens successfully passed the MS exam. The topic of her MS study was "Modelling of the low-void SFR core during ULOF with spatial kinetics". Unprotected Loss Of Flow (ULOF) transient in the low-void Sodium Fast Reactor (SFR) core was simulated, using the TRACE thermal-hydraulic system code coupled to the PARCS 3D nodal diffusion reactor kinetics solver. The new method of the one-group cross sections preparation using the Serpent 2 Monte-Carlo code was developed and successfully applied. One of the conclusions made in the study says that for ULOF in low-void core, 0D and 3D reactor kinetic models provide conservative and best-estimate predictions, respectively.

IAEA TECDOC-1819 on Coordinated Research Project "Benchmark Analysis of EBR-II Shutdown Heat Removal Tests" has been published online: http://www-pub.iaea.org/books/IAEABooks/12247/Benchmark-Analysis-of-EBR-II-Shutdown-Heat-Removal-Tests. The Fast Reactors Group has contributed with static and transient analysis using Serpent 2 and TRACE codes, respectively.

This year FR17 International Conference on Fast Reactors and Related Fuel Cycles: "Next Generation Nuclear Systems for Sustainable, Development" was held in Yekaterinburg, Russia on June 26-29, 2017. The Fast Reactors Group actively participated in this important event contributing as first authors or as co-authors to 12 papers presented at the conference as well as to panel discussions on Small and Medium Sized Fast Reactors. One of the five young nuclear scientists awarded at the conference in frame of the Young Innovator Challenge competition was E. Pettersen who did his master thesis at the Fast Reactors Group.

Janos Bodi, student from University of Birmingham, UK, joined the Fast Reactors Group to make his master thesis on "Development of the CAD models for the European Sodium Fast Reactor". The drawings will be used in the Horizon-2020 ESFR-SMART project for visualization of the concepts and consistent development of the input models for different codes.

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
