Delivery milestone

A remarkable chapter draws to a close

In July 2020, in the middle of the exceptionally challenging Covid-19 pandemic, the ITER Organization marked the start of ITER machine assembly with a small ceremony on site. The cryostat base had been successfully lowered into place—the first in a succession of extraordinary lifting operations that would see the empty...

Last vacuum vessel sector arrives on site

2026-10-02 - Vacuum vessel sector #2, procured in Europe, arrives early in the morning of Friday 2 October. Six years after the arrival of the first vacuum vessel sector, the ninth and final sector is on site.

Upcoming project: assembling the central solenoid structure

2026-09-25 - Now that the central solenoid tower is complete, with six stacked modules, the next phase of work is assembling the central solenoid structure. In this photo, tie plates are being unwrapped.

Last "super" load ready for barge crossing

2026-09-23 - The last "super HEL" (highly exceptional load) of the ITER procurement program is travelling now to the worksite: vacuum vessel sector #2. With the arrival of sector #2 in early October, all super HELs will be safely on site—a category that included all toroidal field coils, poloidal field coils manufactured offsite, and all nine vacuum vessel sectors. On 23 September, sector #2 was loaded on to a specialized barge to cross the inland sea of Berre.

Early morning at the port

2026-09-22 - The last vacuum vessel sector en route to ITER emerges from the hold of a cargo ship just as the sun is rising over the Port of Marseille Fos.

Penultimate sector joins sub-assembly process

2026-09-18 - Vacuum vessel sector #3 is transferred to one of ITER's tall sub-assembly tools where it will become a "sector module" after thermal shielding and a pair of vertical magnet coils are attached.

Safety Day 2026

2026-09-17 - For the sixth consecutive year, Safety Day at ITER promoted best practices and reinforced the project’s strong safety culture. This year’s event brought together 150 volunteers, 1,500 visitors, and 36 booths—including this one, where glasses simulating the effects of marijuana put volunteers’ coordination to the test.

Just a peek

2026-09-17 - ITER's photographer has captured the magnet cold test facility at a particular moment, with the lid slightly open. Inside, is the last 330-tonne toroidal field coil to be tested.

ITER @ IAEA General Conference

2026-09-16 - ITER takes part in the 70th General Conference of the International Atomic Energy Agency (IAEA) in September, where fusion energy is part of the debate. Deepti Choubey, head of ITER Communication, delivers a statement emphasizing how lessons learned during the buildup to ITER operation are already benefitting the fusion community.

400-tonne sector upended

2026-09-16 - Before it can be settled into tooling, vacuum vessel sector #3 must be raised from its horizontal travel position to vertical. That is the job of the ITER upending tools, one of which is seen here in action.

Last ITER vacuum vessel sector leaves Italy

2026-09-16 - The ninth and final sector of the ITER vacuum vessel is leaving Italy. It is expected onsite at ITER in a few weeks.

Third Tritium Plant Summit @ ITER

2026-09-15 - The Tritium Plant Summit provides a forum for the international teams responsible for delivering the tritium plant to exchange progress updates and coordinate approaches as the project moves from design towards manufacturing, installation and commissioning. All systems have now reached final design status and the first equipment is expected in 2028.

ITER and China strengthen cooperation on fusion

2026-09-15 - The ITER Organization and the China Fusion Energy Co., Ltd. (CFEC) have signed a Memorandum of Understanding to further cooperation on fusion engineering and scientific research. It will provide a framework for deeper engagement in areas of mutual interest, including fusion engineering technologies, collaborative research, and international scientific exchange.

Test blanket systems enter final engineering phase

2026-09-14 - This summer, the four tritium breeding concepts that ITER will be testing in its first deuterium-tritium operation phase passed preliminary design reviews. This opens the door to the final engineering phase.

Gaining first-hand insight into progress

2026-09-12 - The visit of Minister of State for Science and Technology Policy, Onoda Kimi, reflects Japan’s longstanding commitment to the ITER project and to advancing fusion as a sustainable energy source for future generations. She was received onsite by ITER's Deputy Director-General for Science and Technology, Kamada Yutaka, and the Deputy Head of the ITER Construction Project, Omae Takayoshi.
