Central solenoid module 2 stacking in ITER Assembly Hall, September 2023

Central Solenoid Stacking Underway

In one corner of the ITER Assembly Hall, work has started on the second of the six central solenoid modules. Once all six modules are stacked one on top of another, they will form the 18-meter-tall, 1,000-tonne ITER central solenoid.

The United States is a partner nation in ITER, an unprecedented international collaboration of scientists and engineers working to design, construct, and assemble a burning plasma experiment that can demonstrate the scientific and technological feasibility of fusion. ITER’s other partners are the People’s Republic of China, the European Union (host), IndiaJapanthe Republic of Korea, and the Russian Federation.

Mission: Produce a self-sustaining burning plasma

US ITER is a DOE Office of Science project managed by Oak Ridge National Laboratory in Tennessee. Partner labs are Princeton Plasma Physics Laboratory and Savannah River National Laboratory. Involvement in ITER provides significant benefits to the US for a limited investment (~9% of construction costs): The US has access to all ITER technology and scientific data, the right to propose/conduct experiments, and the opportunity for US universities, laboratories and industries to design and construct parts. The US contributes procurement of hardware, assignment of personnel, and cash contributions for the US share of common expenses such as personnel infrastructure, assembly, and installation.
