The story so far

History

This one-of-a-kind scientific collaboration dates back to 1985. Premier Gorbachev (former Soviet Union), following discussions with President Mitterrand (France), proposed to President Reagan (United States) that an international project be set up to develop fusion energy for peaceful purposes. At that time, the Soviet Union, the United States, the European Union and Japan formed the parties that agreed to work together. A first design was completed in 2001. China, the Republic of Korea, and later on, India joined the project. On 24 October 2007, they signed an international agreement to build ITER.

2003
Europe offers to host the ITER project
>

The Parties will have to decide the location of the biggest experiment in the field of fusion energy.

2005
ITER to be built in Cadarache, south of France
>

Meanwhile, the seat of Fusion for Energy (F4E), the EU organisation managing Europe’s contribution to ITER, is established in Barcelona.

2006
ITER Agreement signed
>

The seven Parties meet in Paris to sign the agreement establishing the ITER Organization responsible for the phases of building, operation, and decommissioning of the project.

2007
F4E is established
>

The EU organisation gets ready to launch Europe’s first tenders for ITER.

Works begin on the ITER site – 90 hectares of land start to be cleared.

2008
Europe launches its first procurement
>

A tender for the supply of chromium plated copper strand marks the operational phase of F4E.The material will be used in the manufacturing of ITER’s powerful superconducting magnets which will confine and stabilise the machine’s hot plasma.

2009
ITER platform ready for construction
>

The 42 hectare-platform to host the ITER buildings, infrastructure and power supplies is ready. Respecting biodiversity has been key to the works performed. Watch the video

2011
Excavation of the Tokamak Complex is completed
>

This is where the Tritium, Tokamak, Diagnostics buildings will be located.

Some 400 000 t will rest on its lower basemat of the complex.

2014
First concrete poured to create the foundation of the Tokamak Complex
>

The slab covers an area of 9600 m2 and comprises 14 000 m3 of concrete, 3 600 t of rebar and 2 500 embedded plates. Watch the video

2015
Europe’s first piece of equipment is delivered to ITER.
>

Six large-sized tanks, part of the water detritiation system, arrive on-site.

The tanks will play a role in ITER’s fuel cycle system. Watch the video

2016
The ITER Assembly Hall rises from the ground
>

An impressive 100 m long workshop will welcome the bulky components to be put together so as to be installed in the machine.

2017
The ITER site is connected to the grid
>

The infrastructure for direct power supply of 75MVA at 400kV is in place.

2018
The crown is completed
>

A solid base ring inside the Tokamak building, and its 18 radial walls – are completed. The cylindrical concrete structure is able to support the load of the ITER machine (23 000 t).

2019
Manufacturing completed for ITER’s sixth Poloidal Field coil
>

Fabrication concluded for Europe’s first Poloidal Field. Teams moving ahead with final acceptance tests.
The magnet results from the collaboration of F4E (Europe) with ASIPP (China).

2019
End of civil engineering works for Tokamak building
>

The VFR consortium (VINCI, Ferrovial, Razel-Bec) poured the final concrete at the Tokamak building. Approximately 10 types of concrete were developed for its construction.

2020
Two of Europe’s Poloidal Field coils are manufactured
>

The massive magnetic rings will be used to maintain the shape and stability of the ITER plasma.

2020
Europe’s first Toroidal Field coil is completed
>

ITER will operate with 18 TF coils in total. Their role is to confine the super-hot plasma. The impressive D-shape magnet, measuring 17 m x 9 m, weighing 320 t, is the first of the ten TF coils that Europe is responsible for. The remaining eight, plus one spare, will be produced by Japan.
