Overview

  • The Central Solenoid, the electromagnetic core of ITER's tokamak, has been completed and tested in the U.S., marking a major engineering milestone.
  • This 3,000-ton superconducting system, capable of lifting an aircraft carrier, will confine plasma heated to 270 million degrees Fahrenheit for nuclear fusion experiments.
  • ITER, a collaboration of over 30 countries, aims to produce 500 megawatts of fusion power from 50 megawatts of input, demonstrating a tenfold energy gain.
  • The reactor assembly phase is underway at ITER's facility in southern France, with first plasma projected around 2035.
  • The Central Solenoid joins other key components, including six Poloidal Field magnets, in ITER's effort to validate fusion as a scalable, carbon-free energy source.
