NES Publication- LMFNS Compendium

​​The IAEA Nuclear Energy Series publication 

Experimental Facilities in Support of Liquid Metal Cooled Fast Neutron Systems​

Abstract

     The publication presents both an overview and detailed information on experimental facilities currently designed, under construction or operating, in support of the development and deployment of the innovative Liquid Metal cooled (sodium, lead and lead-bismuth eutectic, LBE) Fast Neutron Systems (LMFNS), both critical and subcritical. The overview of these facilities is presented in the chapters of the report, whilst the detailed information is collected as profiles of all the facilities in the form of individual papers contained in a CD-ROM attached to this publication. The profiles, providing a thorough technical description of the facilities, including their specific features for utilization, represent the main component of the Compendium and are the integral part of the report.

 
   By providing the end-users with detailed information on existing and future experimental facilities able to support innovative liquid metal cooled fast neutron systems, the Compendium will facilitate cooperation between organizations with an active programme on these nuclear energy systems and, as a consequence, will enhance their utilization as well as the involvement in the associated experimental programmes of young engineers and researchers to be educated and trained in the field of advanced reactors.
 

 
    In total, the Compendium covers information about 150 LMFNS experimental facilities. Facilities in support of SFR and LFR development and deployment amount up to almost equal numbers: 79 for SFR and 72 for LFR.

    Besides the facilities in support of SFR and in support of LFR there are a few dual-application facilities in support of both designs. These cross-cutting facilities are noted in the overview Tables 3 and 4.

     Individual papers (profiles) follow the standard experimental facility template:
  • General information;
  • Status of the facility;
  • Facilities planned to be operated beyond 2020, even if under design or construction, are considered out of scope for the Compendium
  • Main research field(s);
  • Technical description;
  • Completed experimental campaigns: main results and achievements;
  • Planned experiments;
  • Training activities;
  • References.
    ​The profiles on facilities in support of fast neutron systems are structured according to coolant technologies: 1) sodium cooled Reactors (SFR), 2) lead cooled reactors (LFR), i.e. lead and lead-bismuth cooled reactors.

 The Profiles represent an integral part of the IAEA publication and are also presented in this web-based database entitled "LMFNS Catalogue" (page "LMFNS Facilities Database").
 
Important notes:
  1. LMFNS is a common term for SFR and LFR, both critical and subcritical, including LFR/ADS fast neutron systems.
  2. In this Compendium it is assumed that under the term "lead fast reactor (LFR)" all heavy liquid metal cooled fast neutron systems (FNS) are included, i.e. lead and lead-bismuth cooled reactors, both critical and subcritical installations.
  3. Status of the facility:  Facilities planned to be operated beyond 2020, even if under design or construction, are considered out of scope for the Compendium
