>$1.5 billion to U.S. industry, universities, and national laboratories
2026 Status
Civil construction of the international ITER project is largely complete, machine assembly is in progress, and all components of the U.S.-provided central solenoid superconducting magnet are on site for assembly. Overall U.S. scope for ITER is more than 54% complete, with plasma heating, vacuum, cooling water, and diagnostic systems in active fabrication. ITER members are actively pursuing complementary fusion investments in parallel with ITER progress.
What ITER Will Deliver
ITER will deliver scientific foundations for practical fusion by producing and controlling a self-sustained fusion power source of up to 500 megawatts (MW) for hundreds of seconds. This has not yet been achieved by any fusion system. In addition, ITER will be a valuable R&D facility—much like test reactors are for nuclear energy—providing flexible operations, extensive measurement tools, and testing capabilities for fusion.
ITER also is helping grow the nation’s fusion industry, with more than $1.5 billion contracts placed with companies, universities, and national laboratories (see industry impact.)
