US ITER is a DOE Office of Science project managed by Oak Ridge National Laboratory
The plasma heating team at US ITER has begun production of nine of 10 major components of the electron cyclotron heating (ECH) transmission lines. As of September, manufacturing is complete for the direct-current (DC) breaks, which have been delivered and accepted by the ITER Organization. Eight other major components are now in production, with some […]
Hundreds of ITER videos are available for viewing on the ITER Organization web site as well as on the ITER YouTube channel. Watch as components inside the tokamak core are assembled or view aerial footage demonstrating the scope and size of the ITER project as it is built. Here are direct links to several recent […]
ITER’s third Tritium Plant Summit brought together approximately 70 participants from around the world on Sept. 15-18. Participants included staff from the ITER Organization, industry partners, suppliers, and member nations, including the US ITER tokamak exhaust processing team. Participants at the summit discussed common challenges of using tritium, an isotope of hydrogen that is scarce […]
With the successful installation of the sixth sector module of the vacuum vessel, two-thirds of the ITER plasma chamber is now positioned in the tokamak pit. The lift operation lasted nearly 30 hours and required mobilizing more than 100 staff including crane operators, spotters, engineers, metrology experts, safety experts, and supervisors. Each module is composed […]
Private and public sectors in the United States can request a variety of information from the US ITER project at www.ornl.gov/iterinfo. Available information includes design, testing, and manufacturing details related to US ITER technical scope. Requestors also can be referred to the ITER Organization from this site.
With the successful lift of the final module at the end of June, the stacking of the central solenoid—the powerful magnet at the heart of the ITER tokamak—is now complete. While crucial technical work remains before the magnet is ready to be transferred into the tokamak pit, the completed stack is a milestone moment for […]
US ITER has completed final deliveries to the international ITER fusion project for the central solenoid, the world’s most powerful pulsed superconducting magnet. The most recent deliveries included a turnover tool for handling the 110-ton modules plus bus bars and leads for electrical connections between the modules. Earlier, all magnet modules, support structures and tooling […]
As of early 2026, US ITER has completed three technical systems for the international ITER fusion project: the central solenoid magnet system, the toroidal field coil conductor, and the steady state electrical network. The central solenoid was completed in April 2026 with the final deliveries of tooling and components. Previously the United States had completed […]
The spare central solenoid module arrived safely at the ITER site in mid-January after a weeks-long journey by boat and truck from the United States. “It’s very satisfying to see the transport executed so smoothly,” said Jeff Parrott, logistics and transportation coordinator for US ITER. “There will be other large components we deliver but none […]
The fifth module has been placed on the central solenoid magnet stack in the ITER Assembly Hall. See a video of the delicate operation of moving and positioning the 121-ton module into place. The sixth and final module, delivered to ITER in September, is scheduled to be moved into place at the top of the […]
