1. The LEADER project, the LFR road map, GIF-LFR activities and 2012-2013 LFR news Technical Workshop to Review Safety and Design Aspects of European LFR Demonstrator (ALFRED), European LFR Industrial Plant (ELFR), and European Lead Cooled Training Reactor (ELECTRA) Joint Research Centre, Institute for Energy and Transport, Petten, the Netherlands, 27–28 February 2013 Alessandro Alemberti Alessandro.Alemberti@ann.ansaldo.it

2. SUMMARY • The LEADER project • The European LFR Road Map • LFR GIF Activities • The LFR Global perspective, some important news • A look into the future EU strategic documents

3. The LEADER Project (EU-FP7) • LEADER project started its activities in 2010 with the main goals to: • Develop an integrated strategy for the LFR development • Define a preliminary European LFR Road Map • Identify main issues for LFR development, develop solutions/way fwd • Design a new conceptual configuration of the industrial size plant, the ELFR conceptual design as a reference for the large size reactor plant (600 Mwe) • Design a scaled down reactor, the LFR demonstrator – ALFRED, using solutions as much as possible close to the adopted reference conceptual design of ELFR but considering the essential need to proceed to construction in a short time frame.

4. LEADER PROJECT STATUS • ELFR conceptual design: • A 600 Mwe INDUSTRIAL SIZE REFERENCE CONCEPT • Fuel Assemblies based on hexagonal wrapped option, FA support provided, continuous monitoring for flow blockage, FAs weighted down by Tungsten ballast • Core Bottom grid, lateral restraint for core and shroud • Safety system completely based on passive technology • ALFRED conceptual design: “Demonstration reactor has to be realized in the short term relying on the today available technology. As a consequence, while we should try to design a demonstrator as close as possible to the reference industrial size ELFR, we shall switch (where needed) to proven and available solutions” • Some components of ALFRED different from the design proposed for ELFR • SGs: double wall straight bayonet tubes, continuous monitoring, permits use of SGs tube bundles as part of DHR system, easy coating and/or surface treatment • Decay Heat Remoal Systems: Based mainly on isolation condenser of ELFR • In general other solutions as close as possible to ELFR design • Common features: low core pressure drop (~ 1bar), total pressure drop ~ 1.5 bar, high primary natural circulation • Some differences but completely functionally equivalent

5. Strategic activities of the LEADER Project The LFR Road Map

6. Current Status of GIF LFR PSSC • Provisional System Steering Committee (PSSC) was formed in 2005 • Members included EU, US, Japan and Korea • Prepared initial draft LFR System Research Plan (LFR-SRP) • Systems included a large central station design (ELSY) and a small transportable system (SSTAR) • In 2010, an MOU was signed between EU and Japan causing a reformulation of the PSSC • In 2011, the Russian Federation added its signature to the MOU • In April, 2012, the reformulated PSSC met in Pisa and began the process of revising the LFR-SRP (System Research Plan) • Members are signatories of the MOU: EU, Japan and Russia • US invited to participate as observer • The new PSSC envisions various updates to the central station and small reactor thrusts while adding a mid-size LFR

7. Current Activities of LFR-PSSC • Working meeting of the PSSC : November, 2012 in Tokyo, Japan • Discussion on position paper on safety aspects and issues and LFR SRP • Preparation of GIF Symposium paper and presentation (Craig Smith) • Russian representative declared two FR line development: LFR and SFR • Korea representative will be invited to the next meeting as observer • Seminar on LFR at Tokyo Institute of Technology • Difficult to proceed to SA signature given the present situation (Japan - Fukushima), decision to continue efforts to enlarge LFR MoU signatures • Next meeting in Paris hosted by OECD-NEA on March 7-8, 2013 after FR13

10. The Small Secure Transportable Autonomous Reactor (SSTAR) SSTAR is a small natural circulation fast reactor of 20 MWe/45 MWt, that can be scaled up to 180 MWe/400 MWt. The compact active core is removed by the supplier as a single cassette and replaced by a fresh core. Key attributes include advanced power conversion system, use of natural convection cooling and a long-life core in a small, modular system.

14. The EC Next StepUPDATE of STRATEGIC EUROPEAN DOCUMENTS FROM THE DRAFT of the Introduction to “STRATEGIC RESEARCH INITIATIVE AGENDA” (SRIA) provided to SNE-TP (Sustainable Nuclear Energy – Technology Platform) by ESNII (European Sustainable Nuclear Industrial Initiative on Fast Reactors - SFR,LFR,GFR) With respect to the 2010 technologies evaluation, sodium is still considered as the reference technology since it has broader technological and reactor operations feed-back. The Lead Fast Reactor technology has significantly extended its technological base and can be considered as the shorter-term alternative technology, whereas the Gas Fast reactor technology has to be considered as a longer-term alternative option. For the development of the Lead Fast Reactor, maximum synergy of activities will be sought with the MYRRHA development to optimize resources and planning. For the LFR demonstrator ALFRED the main focus should be on design activities typical of  a critical reactor connected to the grid, as well as on R&D activities on the lead coolant, addressing the specific characteristics of lead with respect to lead-bismuth. 4 ESNII projects: ASTRID (SFR), MYRRHA(ADS-LBE), ALFRED (LFR), ALLEGRO (GFR)
