Preparing ITER operation on present tokamaks
Preparing ITER operation on present tokamaks
The ITER like Wall experiment JET
(>2009)
• Materials of ITER plasma facing
components will be installed in JET
(2008-2009)
• ITER relevant safety issues (T
inventory with Be and W; dust from
W and Be etc.)
• Progressing the plasma scenarios
in the most relevant conditions: a
key step in support to ITER

The ITER design is based largely on the success of JET
and other tokamaks: high confidence in extrapolation
ITER prepares for the demonstration reactor DEMO

Procurements in kind
A unique feature of ITER is that almost all of the machine will be
constructed through in kind procurement from the Parties
