ITER Organization

🇫🇷 Saint-Paul-lez-Durance, FR · Active

The ITER Organization is the intergovernmental body, established in 2007 under an agreement signed in November 2006, that is building and will operate ITER, an experimental tokamak at Saint-Paul-lez-Durance in southern France, next to the Cadarache research centre. Its seven members are China, the European Union, India, Japan, Russia, South Korea and the United States. ITER's goal is a plasma that releases ten times more fusion power than the heating power injected into it (a plasma gain of 10) and 500 MW of fusion heat. Under the revised schedule published in 2024, operation with deuterium–deuterium plasma is to start in 2035 and deuterium–tritium operation in 2039.

Role
Consortium, Operator

It is the operator of record for ITER (under construction). ITER carries only planned figures, which are targets rather than results.

Terms

Tokamak
Doughnut-shaped magnetic confinement using a strong toroidal field plus a current driven through the plasma itself. The most-studied configuration, and the one ITER uses. Its main open problem is heat exhaust at the divertor, where the plasma edge concentrates power onto a small area, together with the risk of disruptions: sudden, uncontrolled losses of the plasma current.
Deuterium–tritium
Lowest ignition threshold; 80% of energy in 14.1 MeV neutrons. The reference fuel for every near-term net-gain claim.
