About ITER Organization

ITER is an international, large-scale scientific collaboration intended to prove the viability of fusion as an energy source, and to collect data that will contribute substantially toward the design and operation of the subsequent first electricity-producing fusion power plants. To achieve this goal, seven Members (China, European Union, India, Japan, South Korea, Russia and the United States) have joined forces to build the ITER Tokamak: the world’s largest fusion device. The seven Members signed the ITER Agreement in 2006, and have agreed to share in every aspect of the project: science, engineering, procurement, financing, staffing, intellectual property, etc. The ITER Project is based in Saint-Paul Lez Durance, in the south of France, where the ITER facility is currently under construction.
