General Atomics pioneers advanced technologies with world-changing potential. We have been at the cutting edge of energy innovation since the dawn of the atomic age more than 60 years ago. With scientists and engineers continually advancing the frontier of scientific discovery, we serve our growing planet's needs through safe, sustainable, and economical solutions across a comprehensive array of key energy technologies

Our research and development portfolio includes:

  • Fusion: As a world leader in fusion energy research, GA scientists and engineers are engaged in developing both magnetic and inertial confinement fusion as a safe, clean and virtually unlimited energy source for the future.
  • Fission: Pioneering energy systems from the world's most widely used test reactor, TRIGA, to developing next generation advanced reactors for economic sustainable energy.

GA has been an innovator in Magnetic Fusion Energy (MFE) for more than 50 years. The DIII-D National Fusion Facility, operated by GA for the U.S. Department of Energy, is the largest MFE device in the nation and one of the largest in the world. Research in DIII-D addresses a range of issues spanning basic understanding of the physics of fusion plasmas and establishing a scientific basis for operation of future fusion devices including the ITER international project. ITER is now under construction in France by a consortium of 35 nations including the U.S., and it is expected to demonstrate high fusion gain upon completion. GA is also engaged in manufacturing components for ITER including the Central Solenoid, which will be the world's most powerful superconducting magnet that will form the beating heart of the ITER device.

Our Inertial Fusion Technologies program focuses on the inertial confinement approach to stockpile stewardship and fusion energy. We are a leading manufacturer of precision targets, including for the National Ignition Facility in California.

In fission energy, GA has been an important pioneer with more than 50 years' experience in nuclear energy and fuels. GA-Energy Group is developing the revolutionary Energy Multiplier Module – EM2 – a modular advanced fast reactor that can run on the spent fuel of current reactors.

GA focuses its energy business in three primary areas: magnetic fusion, inertial fusion, and nuclear fission. Review our range of work by subject area to learn more about what we do.
