Cold, powerful magnet will help control hot plasma in fusion reactor

A team at ITER, an international experimental fusion reactor in southern France, prepare on Feb. 10, 2022, to move one of six modules for a central solenoid, a powerful superconducting magnet being built by General Atomics in California under the management of Oak Ridge National Laboratory.

A magnet so powerful it could lift an aircraft carrier six feet into the air was designed in a project managed by Oak Ridge National Laboratory. It will be used in an international experimental reactor in southern France to produce energy using fusion, the same process used by the sun and other stars to create heat and light. If successful, the reactor could revolutionize energy production, potentially showing how to provide a nearly limitless energy supply without planet-warming carbon dioxide emissions or long-lived radioactive wastes.

Six modules for the reactor’s central superconducting magnet, plus a spare, are being made by General Atomics in Poway, California. Two of the modules have already been shipped to France. Two more are completed, with one of those expected to ship this year. The remaining three are more than 60% complete, and manufacturing should be done this year, said John Smith, General Atomics senior director of engineering and projects.

A member of the technical staff at ITER, a magnetic fusion device in southern France, will discuss man’s quest for fusion and the role of ITER in a Friday evening lecture in Oak Ridge.

The lecture starts at 6 p.m. Friday, May 20, at the American Museum of Science and Energy. It will be by Mark Henderson, member of the Technical Staff, ITER Organization in St. Paul-les-Durrance, France.

Henderson will provide a first-hand account of the wide scope of technologies involved in operation of the ITER tokamak (the magnetic fusion device), as well as the current status of design, development, and construction of the experimental fusion facility, a press release said. ITER is the only fusion device in the world that is presently being designed to achieve a burning plasma of hydrogen isotopes. [Read more…]
