  1. Association EURATOM-CEA Presented by A. Bécoulet

  2. Outline • Introducing Association Euratom-CEA • Programmatic Priorities for the coming decade • Structure & Organization • Concluding Remarks

  3. march 25th, 1957: Signature of the EURATOM treaty in Rome Association EURATOM-CEA: the first Association (1959) • The Association includes: • CEA/DSM/IRFM ~ 270 permanent CEA staff + ~ 60 non permanent • Fédération de Recherche Fusion par Confinement Magnetique + other CEA Institutes ~ 75 ppy incl. PhD (280 persons involved)

  4. Technological Research (DRT) Nuclear Energy (DEN) Military Application (DAM) Physical Sciences (DSM) (~2300) Life Sciences (DSV) IRFM: A Research Unit within CEA IRFM : Magnetic Fusion Research Institute (~280)

  5. IRFM and the French National Network Lille LPP INRIALMPGM • Equilibrium & MHD stability • Turbulence & transport • Edge plasma, radiation and Plasma facing Components • Heating & Current Drive (waves, beams) Paris LMD LIMHP ENSAM/LIM Palaiseau LPP CPhT Orsay LPGP LCAM Villetaneuse LIMHP Strasbourg LSIIT IRMA INRIA Nancy LPMIA INRIA IECN Orléans CEM-HTI Grenoble CRTBT SIMAP LPSC • Materials • Diagnostic & data processing (operational safety) Lyon LMI Ampere Bordeaux IMB/LABRI INRIALCTS Cadarache CEA Nice LJAD INRIA Toulouse MIP LAPLACE LCAR IMT/MIP Montpellier PROMES Marseille PIIM, CPT LATP, M2P2 CP2M MSNM-GP LP3, IUSTI Toulon SIS

  6. Outline • Introducing Association Euratom-CEA • Programmatic Priorities for the coming decade • Structure & Organization • Concluding Remarks

  7. The CEA strategy a wide spectrum to maintain at national level a global assessment capability on fusion energy development Objective 1 ST1: Participating in the realisation of ITER and the Broader Approach projects JT 60 SA Objective 2 ST2: Preparing the operation of next generation devices ST3: Enhancing and focusing physical understanding along empirical and first principle approaches, Objective 4 ST4: Developing a capability for fusion reactor conceptual studies.

  8. The CEA strategy IRFM overall challenge, a progressive and challenging transitionto a fusion research focused on ITER Objective 3 M1: Adapting its organisation and its manpower M2: Developing strong national, European and international networks and initiating close industrial cooperation M3: Securing the resources necessary in achieving these aims.

  9. CEA strategy implementation guidelines CEA has the ambition to be a major contributor, to the experimental scientific and operational program of ITER. • Direct contribution to the development and construction of ITER, and of BA elements • Preparation of the scientific exploitation of ITER: Heating and current drive, PFC’s,…, and key physics issues (turbulence, ELMs, disruption mitigation, plasma control …) by dedicating Tore Supra to this aim and prototyping the relevant tools • Keeping a high standard at the forefront of physics activity (experiment and theory/modelling) CEA also aims at developing a global vision of fusion as a potential energy source (long term aim): reactor studies have been re-activated

  10. JT 60SA TF coil Development&construction of ITER & BA projects SelectedTopics: • Design Integration • Diagnostics (Vis/IR PFC monitoring, magnetics, reflectometry) • ICRH & LHCD • Cryomagnetism • Plasma facing components, • Test blanket modules LHCD full implementation in ITER 7 m

  11. Preparation of the scientific exploitation of ITER TITAN SelectedTopics: • Control of long pulse discharges in actively cooled environment, • Platforms&test facilities for ITER • Integrated modelling, • Plasma engineering & real time control • Ab initio simulations W7-X JET

  12. A mutation of the Tore Supra Facility is proposed WEST : WEnvironment in Steady-state Tokamaks • Proposal: Turn Tore Supra into a Test Bed besides ITER, dedicated mostly to tungsten (W) actively cooled PFCs (requires an X-point configuration) • Motivation: • Risk minimisation (manufacturing and operation) on ITER relevant technology • Unique capability within the decade • Key for ITER, but also for EAST,JT60-SA, W7X... • Feasability study achieved in 2010, welcomed by high level international panel and by French Gvt Evaluation panel; conceptual study underway Dedicating Tore Supra to ITER preparation and risk minimisation

  13. GYSELA Electric potential Fluctuations Preparing for the numerical tokamak (« VENUS ») • Through intensive collaborations (Fédération de Recherche, EU, …) IRFM is participating to a world class tools development, with a strong focus on its scientific outputs • HPCs yield access to ab initio calculations, allowing to address fully developed tokamak physics (« numerical tokamak » + confrontation to experiment) JOREK

  14. Power Plant Physics & Technology Developing a capability for fusion reactor conceptual studies • System code for DEMO (modularity, evolutivity, ITM-based) • Plasma scenario; magnets; blanket; divertor; He-cooling • H&CD systems optimisation using scenario • Exploring innovative PFC concepts & materials (collaboration with FR-FCM)

  15. Challenges in front of us The next 25 years: a brand new era for fusion • MAKE ITER&JT60-SA A SUCCESS! • Burning Plasma Physics • Validation of magnetic fusion as a nuclear process • Advanced Tokamak and Steady-state operation • Controlled and safe plasma discharges • Integrated modeling and flight simulators for operation • CREDIBLE REACTOR CONCEPTUAL DESIGN! • Full validation of reactor-relevant configuration • Materials for fusion reactors (R&D, tests, simulation) • First principle numerical description of plasma discharges (multi-physics/multi-scale)

  16. Challenges in front of us 2010-2020: Adapting or Vanishing • A commonly agreed long term programme, adapting the competences of the entire fusion community to next step challenges (techno., exp., theory&modelling) • Innovative structures: • Associations’ network: strength and solidarity • Associations’ staffs&tools as a seed for innovation and training/adaptation of competences • IO-F4E-Association project-oriented partnership • EFDA implementing the common undertakings • JET; HPC-FF; IFERC; preparing JT-60SA and ITER operation…. Towards a credible fusion reactor perspective • EU industry & innovation aspects integrated in the programme
