Status of the US contributions to the ITER Project*

As the international ITER project prepares for tokamak assembly, US ITER continues to deliver, fabricate and design essential ITER hardware systems. As of April 2021, planned US hardware deliveries are 40% complete, with two systems already fully delivered. In 2021, a major milestone was achieved: the successful completion of testing plus shipment of two central solenoid magnet modules to the ITER site. The central solenoid is the only ITER magnet to undergo post-production testing that simulates the ITER operational environment, with cryogenic temperatures of 4.5 degrees Kelvin and powering to 40,000 amperes. Disruption mitigation testing continued on JET tokamak, using US ITER and ORNL-developed hardware. Looking forward to 2022, US ITER is continuing to complete essential deliveries for the central solenoid support structures, tokamak cooling water system, and vacuum system, and is advancing post-first plasma design to prepare for fabrication and deliveries that are needed after initial operations. ORNL, which manages US ITER for DOE Office of Science, is also engaging with partners across the US to prepare for ITER science operations.
