ITER Organization

What ITER Organization does

ITER Organization is an international intergovernmental research organization established by treaty in 2006 to demonstrate the scientific and technological feasibility of fusion energy as a large-scale, carbon-free power source. The organization is constructing the ITER Tokamak, a doughnut-shaped magnetic confinement fusion device weighing 23,000 tonnes across a 28-meter diameter at its Cadarache site in Saint-Paul-lez-Durance, France. The machine comprises approximately one million components and ten million parts, including nine vacuum vessel sector modules, toroidal and poloidal field coils, and a central solenoid magnet system described as the most powerful pulsed superconducting magnet ever built. The project targets first-plasma operations in 2034, initial fusion power generation by 2035, and a gain factor of Q≥10, meaning ten times more fusion power output than input heating power.

The organization is governed by the ITER Council on behalf of seven Members (China, the European Union including Switzerland, India, Japan, the Republic of Korea, the Russian Federation, and the United States) representing 35 nations, each of which contributes funding and in-kind components through Domestic Agencies. No commercial products or services are sold; the project's value proposition is the demonstration of fusion reactor technology and training of fusion scientists and engineers. Supporting systems include the CODAC integrated control system and the Tokamak Systems Monitor, which incorporates a machine learning-based anomaly detection module. The Private Sector Fusion Engagement (PSFE) project, launched November 2024, provides private fusion startups access to ITER's engineering documentation, simulation software (IMAS and PCSSP), and topical research groups. Cumulative project cost has grown from an original ~$5.5 billion to nearly $22 billion.

Core offering

ITER Organization is building the world's largest and most powerful tokamak fusion device in Saint-Paul-lez-Durance, France, designed to prove the feasibility of nuclear fusion as a large-scale, carbon-free energy source. The organization, an intergovernmental collaboration of 35 nations, oversees construction, assembly, and will operate the 23,000-tonne ITER machine—comprising one million components and ten million parts—to achieve fusion power production at power plant scale, with first plasma targeted for 2034.

Product overview

ITER Organization operates the International Thermonuclear Experimental Reactor (ITER), the world's largest fusion research facility located in southern France. The core product is the ITER Tokamak—a magnetic confinement fusion device designed to prove the feasibility of nuclear fusion as a large-scale, carbon-free energy source. Supporting the tokamak are key systems including CODAC (the integrated control and data acquisition system), and the Tokamak Systems Monitor which incorporates machine learning-based anomaly detection for operational monitoring. ITER also offers educational programs including the ITER International School, ITPEA topical research groups, and the ITER Robots competition. The Private Sector Fusion Engagement project facilitates collaboration between ITER and private fusion companies through knowledge-sharing mechanisms. The organization produces the ITER Podcast covering fusion science and project progress. Thirty-five nations collaborate on this project, with first plasma operations scheduled for 2034 and initial fusion power generation targeted for 2035.
