General Atomics Awarded Contract to Manufacture Superconducting Magnets


Jul 21, 2011

SAN DIEGO – General Atomics (GA) was awarded a subcontract by UT-Battelle, Oak Ridge National

Laboratory, home to the US ITER Project Office, and funded by the U.S. Department of Energy's Office

of Science, to produce seven superconducting magnets, six of them to be configured as the Central

Solenoid for the ITER Tokamak fusion experiment.

ITER is an experimental facility that aims to demonstrate the feasibility of fusion energy for the

commercial power grid. The goal is to produce fusion power that is at least ten times greater than the

external power delivered to heat the plasma. ITER is now under construction in southern France as a joint

project of the European Union, India, Japan, People's Republic of China, Russia, Republic of South Korea

and the United States.

The Central Solenoid is a key system for ITER; it drives 15 million amperes of electrical current in the

fusion plasma to help confine it. Each of the seven Central Solenoid modules GA is to fabricate will

contain 6.5 kilometers of superconducting cable, will be four meters in diameter and two meters tall, and

weigh 110 tons. The superconducting cable will be provided by Japan. The ITER Central Solenoid will be

the world's largest pulsed superconducting magnet.

For this project, GA will employ about 80 engineers and technicians in the San Diego area. Additionally,

numerous subcontractors in the United States and Europe will participate.

Fusion powers our sun and the stars, and when realized on earth, it will be an ideal source of energy.

There is an endless fuel supply on earth to support the production of fusion energy, as well as existing

electrical grids to support large-scale electricity distribution. Fusion energy emits no greenhouse gases, is

inherently safe, and poses no long-term waste disposal issues.

About General Atomics
