More than 800 companies in 46 states have contributed to US ITER. These companies have established the capability to produce first-of-a-kind components and technology as they deliver innovative fusion engineering, testing, and manufacturing for ITER technical systems.
U.S. industry also benefits from growth of the fusion supply chain and workforce, as well as access to ITER information relevant for a variety of fusion and high-tech manufacturing efforts.
ITER members are working together to build a fusion research and development platform that will provide scientific and technological understanding of an industry-scale self-sustained fusion power source for hundreds of seconds with up to 500 megawatts of fusion power and a fusion power gain (Q) of 10. This is essential knowledge for industry to evolve from concepts to practical fusion systems.
Most US ITER funding for hardware contributions goes to U.S. industry,
universities, and national laboratories to support research and development,
design, and manufacturing for 12 essential systems that the United States is contributing to ITER.
