The CEA strategy
a wide spectrum to maintain at national level a
global assessment capability on fusion energy
development
ST1 Participating in the realisation of ITER and
the Broader Approach projects
Objective 1
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,
ST4 Developing a capability for fusion reactor
conceptual studies.
Objective 4
8
The CEA strategy
IRFM overall challenge, a progressive and
challenging transition to 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.

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, PFCs,, 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
Developmentconstruction of ITER BA projects

• Selected Topics
• Design Integration
• Diagnostics (Vis/IR PFC monitoring, magnetics,
  reflectometry)
• ICRH LHCD
• Cryomagnetism
• Plasma facing components,
• Test blanket modules

LHCD full implementation in ITER

Preparation of the scientific exploitation of ITER
TITAN

• Selected Topics
• Control of long pulse discharges in actively
  cooled environment,
• Platformstest 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 W Environment 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
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
• HCD systems optimisation using scenario
• Exploring innovative PFC concepts materials
  (collaboration with FR-FCM)

15
Challenges in front of us
