Découverte du projet Iter 2026

Tour schedule and conditions :
One-hour presentation at the visitors' center, followed by a tour of the platform by bus (subject to accessibility conditions at the time of the visit).
Reservations must be made at least 10 days before the visit at the Gréoux les bains Tourist Office. Please note: For this visit, you must arrive at the Iter center by your own means, 15 minutes before the start of the visit.
Pants (no skirts or shorts) and flat, closed-toe shoes are required.
An official identity document is required for admission to the site (passport or identity card).
Unfortunately, ITER is not accessible to people with reduced mobility.

What is ITER?
In France's Bouches-du-Rhône region, 35 countries are involved in the construction of the largest tokamak ever designed, a machine designed to demonstrate that fusion - the energy of the Sun and stars - can be used as a large-scale, CO2-free energy source to generate electricity.
The results of ITER's scientific program will be decisive in paving the way for the fusion power plants of tomorrow.
ITER will be the first fusion facility capable of producing a net amount of energy. The machine will produce long-duration plasma discharges and will also test, for the first time, the technologies, materials and plasma regimes required to generate electricity on a commercial scale.
Thousands of engineers and scientists have contributed to the design of ITER since the idea of international collaboration on fusion energy was first mooted in 1985. The ITER Members (China, the European Union, India, Japan, Korea, Russia and the United States) have committed to a thirty-five-year collaboration to build and operate the ITER experimental facility. A demonstration reactor can be designed on the basis of this feedback.
Fusion is the energy source that powers the Sun and stars. In the extreme pressure and temperature conditions at the heart of these stellar bodies, hydrogen nuclei collide and fuse to form helium atoms, releasing considerable amounts of energy in the process.
