2. ƒ The ITER Project aims to demonstrate the scientific and technological
feasibility of fusion power for peaceful purposes.
ƒ Iter project is an international cooperation between countries which
represent more than 50% of the world’s population.

3. Fusion: the fundamental principle
Einstein’s famous equation:
E = mc2
Energy = mass x (speed of light)2
Mass loss of 4 milligram in 1 gram
⇒ 1 gram of fusion fuel ~ 2000 gallons of oil

+ Mass loss = Energy
5. •Fuel: abundant, world‐wide distributed:
• sufficient deuterium in seawater for millions of years
• tritium is produced from lithium
‐ conservative lithium ore recovery estimates indicate sufficient
supplies for thousands of years
‐ sufficient lithium in seawater for millions of years
•Safety: no risk of major accidents:
• reactor contains fuel for only a few seconds burn
•Waste: no long‐term burden:
• low radio‐toxicity after < 100 years
Why Fusion ?
6. • Long pulse plasma have yet been tested but with more energy than
the output power while net gain of energy has been tested but during
very short periods.
• The goal of the ITER fusion program is to produce a long net gain of
energy and set the stage for the demonstration fusion power plant to
come.
• ITER has been designed to produce 500 MW of output power for 50
MW of input power. The expected duration of each plasma pulse
during ITER operation is 1000 second
• Temperature combines with density in our Sun's core to create the
conditions necessary for the fusion reaction to occur. The
gravitational forces can not be recreated on Earth, and much higher
temperatures are necessary to compensate. In the ITER Tokamak,
temperatures will reach 150 million°C.
Why Iter ?
8. ¾ ITER Organization (IO):
ƒ The ITER Organization was formally established on 24 October
2007.
ƒ The purpose of the ITER Organization is to finalize the design,
construct, exploit and de-activate the ITER Facilities.
ƒ Iter Organization is an international Organization with an
international status, like United Nations, with specific legislation and
rules of tendering.
ƒ IO is the Nuclear Operator.
¾ Domestic Agencies:
ƒ The seven Members have all created Domestic Agencies to
manage their “in-kind” contribution to ITER. The EU Domestic
Agency is referred to as Fusion for Energy (F4E) and is based in
Barcelona, Spain.
ITER Project – Key Entities
9. ¾ France, CEA and AIF:
ƒ France is referred to as the Host State
ƒ CEA is referred to as the Host Organization and has set up a
specific agency to manage a range of issues related to the
hosting of ITER. This agency is called Agence ITER France.
¾ Financial contributions
ƒ EU contributes 46% of construction costs
ƒ Each of the other 6 members contribute 9% each.
ƒ In the operational phase EU contributes 34% of costs with
other members 10 to 13%

10. Procurement Arrangement Status
ƒ The IO and DAs have signed more than 100 PA,
ƒ These PA organize the in-kind contribution of each DA
representing approximately 90% of the total procurement
value for the construction of ITER
ƒ Each DA negotiates contracts with local contractor in
accordance with the scope of the signed PA : 1 800 industrial
contracts have yet been signed
