Presentation on fusion R&D priorities and EFDA, B. Weyssow
          The European fusion research programme aims at
             developing fusion as an energy source,
          i.e.
          developing the knowledge in physics, technology and
             engineering required to design and build fusion
             power plants.


                   => power plant-oriented strategy
                          => key steps in this strategy: ITER and DEMO
                          => ‘Fast Track’ approach:
                          DEMO = single step after ITER
                          IFMIF (materials test facility) operating
                                                          in parallel to ITER

                        What we expect from ITER
  • The scientific demonstration of fusion: a Burning Plasma at
    Q=10
  • Development of long pulse/steady state modes of plasma
    operation (with a target of power amplification Q=5)
  • Functional tests and test under neutrons of Test Blanket
    Modules (tritium breeding)
  • Demonstration of a number of key components close to
    power plant requirements (magnets, vessel, T plant, safety,
    etc)

   a key input to support the launch of DEMO construction
    in about 20-25 years
   a necessary input, which however needs to be
    complemented by a significant accompanying
        programme in technology and physics

                                                             CORE PROGRAMME (1/2)
                                As recommended by the Facilities Review Panel (October 2008)

 During the period of ITER construction the key strategic R&D emphasis should
 be on

 A1) Supporting ITER construction and preparation for operation
 • Design and construction of ITER systems and components
 • Resolving ITER physics issues which might limit the performance, constrain the
 accessible parameter space and/or impact on the operational reliability;
 • Preparing rapid start-up of ITER targeting promising operational regimes;
 • Strengthening diagnostic and modelling capabilities and fostering developments
 for improved solutions.
 A2) Preparing DEMO design, simultaneously carrying out long lead R&D by
 • Strengthening the materials research programme for DEMO and future
 fusion power plants and establishing experimental means for validation;
 • Advancing Tokamak and Stellarator concepts for optimizing the path towards
 DEMO and a commercial fusion power plant;
 • Establishing a DEMO group for proceeding towards the definition of a conceptual
 DEMO design, steering the DEMO R&D programme and preparing industrial
 involvement.

                                                             CORE PROGRAMME (2/2)
                                As recommended by the Facilities Review Panel (October 2008)

  During the following decade the focus must shift towards

  B) Preparing for DEMO construction, based on ITER and the accompanying R&D,
  with increased involvement of industry and utilities, by focusing on
  • Achieving the goals of ITER in DEMO relevant conditions with emphasis on
  steady-state aspects;
  • Developing a blanket and auxiliary systems compliant with DEMO conditions;
  • Optimising and validating suitable materials and components for DEMO;
  • Assessing concept improvements for the Tokamak and the potential of the
  Stellarator for optimizing the path towards commercial fusion power;
  • Developing a “numerical burning plasma device” for the detailed prediction of
  fusion performance and assistance in the definition and design of DEMO;
  • Establishing the engineering design for DEMO.

  These ITER and DEMO priorities must be complemented by

  C) Pursuing innovation

  D) Maintaining and renewing the staffing basis of the Programme

           Fusion Fellowships Programme
       -    up to 10 post-docs per year selected among proposals from Associations

      - fellowships awarded according to the sole quality of the applicants and
     their proposals => develop a brand of excellence

Presentation on fusion R&D priorities and EFDA, B. Weyssow
                                                             Summary
       -     The priorities for fusion R&D are clearly set (the Facilities Review
             process has been very useful and ITER should guide a significant R&D
             programme); a strong accompanying programme is needed (and the
             need is recognised), but financial constraints are likely to be severe over
             several years

       -   The coordinated activities under EFDA cover a wide range of physics
          and technologies issues aiming at supporting ITER and developing
          fusion energy
        => Further focusing of the future EFDA programme along the 7 R&D Missions

       -     JET brings key results in preparation of ITER (ICRH, ripple, ELM pacing,
             plasma scenarios)
       => The JET ITER-like Wall (with a possible DTE2) will be a key experiment
             worldwide over the coming 5-6 years

       -     Development of Human Resources is among top EFDA priorities
