New ITER VR Tour

Discover the worksite in 360°!

UNLIMITED ENERGY

Fusion, the nuclear reaction that powers the Sun and the stars, is a potential source of safe, non-carbon emitting and virtually limitless energy. Harnessing fusion's power is the goal of ITER, which has been designed as the key experimental step between today's fusion research machines and tomorrow's fusion power plants.

AMAZING MACHINE

One million components, ten million parts ... the ITER Tokamak will be the largest and most powerful fusion device in the world. Designed to produce 500 MW of fusion power for 50 MW of input heating power (a power amplification ratio of 10), it will take its place in history as the first fusion device to create net energy.

35 countries, 35 years

ITER Members China, the European Union, India, Japan, Korea, Russia and the United States have entered into a 35-year collaboration to build and operate the ITER device. A two-decade research program is planned during which the Members will share in the experimental results and in any generated intellectual property.

MASSIVE CONSTRUCTION

ITER construction is underway now. On the ITER site, buildings are rising; abroad, machine and plant components are leaving factories on three continents. In the years ahead, over 4,000 workers will be required for on-site building, assembly and installation activities.
