JET a powerful asset to prepare ITER operation

• plasma parameters closest to those of ITER (R
  3m Ip up to 4 4.5 MA alpha particles
  confined ITER plasma shape)
• the only Tokamak that handles Tritium
• tests of several ITER-relevant technologies e.g.
  unique remote handling capability, ITER-like
  ICRH-antenna, burning plasma diagnostics
• unique capability to use the same plasma facing
  materials as foreseen for ITER (beryllium) gt
  ITER-like wall project

• JET
• Routine performance of in-vessel remote handling
  tasks

14 MeV Neutron tomography Studies of
tritium transport Excellent capability to
predict T transport confirmed by 14 MeV D-T
neutrons tomography
11
ITER-like ICRH antenna

• Antenna assembly ongoing
• Installation during Winter/Spring 07 shutdown
• Aim at demonstration of ITER ICRH antenna concept
  
• ELM resilience
• High power density

12
JET preparing ITER operation

• Materials of ITER plasma facing components will
  be installed in 2008-2009
• CFC tiles to be replaced by Be tiles and W
  tiles W-coated tiles
• A key step in support for ITER
• Plasma scenarios fully compatible with Be W
• Mixed materials issues
• Control of power transients
• Reduced T retention

13
JET a facility collectively used in preparation
of ITER
Participation of European Physicists in JET 2006
Experimental Campaigns

• About 300 different European physicists and
  collaborators from USA, Japan, Russian
  Federation, China conduct experiments on JET
• Brazilian participation through Portugal

EFDA Technology Activities

• Preparing for the construction of ITER
• Preparing in the longer term for DEMO
• Activities include
• research and development work
• design tasks
• manufacturing and testing of components
• EFDA coordinates the technology activities in the
  Associations and European industry

ITER Lines of Activities (1)
Technology Workprogramme 2006 - 2007
Activities focused on the design and RD towards
the ITER procurement, defined in close
collaboration with the ITER International Team
(IT)

• Assisting the IT in the preparation of the most
  urgently needed technical specifications
  (magnets, vacuum vessel, buildings and site
  preparation).
• Investigation on the manufacturing of the most
  critical components (divertor, vacuum vessel,
  shield modules).
• Preparation of European test facilities (Dipole,
  HELOKA, DTP-2, ECRH Test Facility, HeFUS3)

18
Technology Workprogramme 2006 - 2007
ITER Lines of Activities (2)

• Focused effort in areas where design and RD are
  still needed Machine Assembly, Remote Handling,
  ITER Test Blanket Modules, Diagnostics, Heating
  and Current Drive.
• Assisting the IT in the preparation of safety and
  licensing documentation for ITER and related
  safety studies.
• Preparing EU laboratories European Industries
  for ITER construction.

ITER Vessel / In-Vessel
Full-Scale Vertical Target Prototype
Thermal fatigue testing of the full-scale
divertor vertical target prototype manufactured
by HIP was previously reported with 1000 cycles
at 20 MW/m2 plus additional 1000 cycles at 23
MW/m2 on CFC. The testing has now been
completed also on the W armoured part where 1000
cycles at 20 MW/m2 have been achieved.

2 x 3 metre, curved parts of the walls of the VV
need to be 3-D formed. A study being carried out
to determine press shape and forces required.
