In a comprehensive new article in Nuclear Fusion, ITER Director-General Pietro Barabaschi and colleagues outline the progress of ITER and reaffirm the project’s central role in bringing fusion energy from experimental science to industrial reality. 

After a period of restructuring, contract adjustments, and technical recovery, the project is now advancing under a revised plan known as Baseline 2024, designed as a realistic and achievable path to the first experiments, deuterium operation, and ultimately deuterium-tritium fusion with a gain of Q ≥ 10. Over the past two years, the organization has reported its strongest performance to date, maintaining schedule and cost targets while accelerating assembly and manufacturing activities. 

Major milestones include completion of all superconducting magnets, start of series production of tungsten plasma-facing components, and renewed progress in tokamak assembly following successful repairs to key elements. Large plant systems such as the cryogenic infrastructure are operating, and critical test facilities are coming on line as the project transitions from construction to integrated commissioning. 

The authors describe how, despite the emergence of new fusion actors, ITER’s mission is unchanged: to demonstrate integrated, industrial-scale fusion and provide the knowledge and technology needed for future power plants. In that sense, they argue, ITER is not competing with the expanding fusion ecosystem—it is laying its foundation.

The program for this summer's 15th ITER International School is now available and pre-registration is open on the event website.

Since its launch in 2007, every ITER International School has focused on a specific theme. The 15th School, to be held in Chengdu, China, from 20–24 July 2026, will explore the engineering of heating and current drive systems as well as the physics processes undergirding their use for plasma heating, current drive, and the control of plasma scenarios in ITER and other magnetic fusion devices.

The organizers of the event—the Engineering & Technical College of Chengdu University of Technology and the Southwestern Institute of Physics (SWIP)—have now opened the webpage for pre-registration. The program for the five-day event is also consultable on the website.
