Fission Energy Systems
Nuclear Technologies and Materials
Where TRIGA® Began, Nuclear Innovation Endures
General Atomics Electromagnetic Systems (GA-EMS) is developing next-generation nuclear reactors, fuels, cladding, and reactor materials to provide unmatched safety, performance, and longevity across energy, defense, space, and research applications.
Silicon Carbide (SiC) Fuel Rods
Engineered for Extremes—SiC Composites for Nuclear, Space, and Flight.
At General Atomics Electromagnetic Systems (GA-EMS), composites are a core capability driving innovation across nuclear, space, and flight systems. Our advanced materials, including silicon carbide (SiC), ceramics, and high-performance polymers, enable compact designs, improved fuel efficiency, and exceptional durability in the world's harshest environments.
Advanced Terrestrial Reactors
Proven Designs. Modern Performance. A Safer Energy Future
General Atomics Electromagnetic Systems (GA-EMS) designs advanced nuclear reactors guided by three core principles: safety, economic competitiveness, and waste minimization. As a pioneer in nuclear innovation since 1955, GA-EMS continues to lead the development of commercial terrestrial systems that deliver resilient, scalable energy for communities, remote sites, and specialized missions.
Space Nuclear Power and Propulsion
Reliable Power. Relentless Propulsion.
Solar power fades in shadowed craters and distant orbits. Chemical propulsion has limited burn and would necessitate refueling. Nuclear systems offer what others cannot: sustained power, high-efficiency propulsion, and unmatched resilience in extreme environments.
Materials Acceleration, Innovation and Transition Exchange (MAITrX)
The Materials Acceleration, Innovation and Transition Exchange (MAITrX) is General Atomics Electromagnetic Systems’ (GA‑EMS) state‑of‑the‑art, integrated network of facilities for the development, prototyping and manufacturing of advanced materials for extreme environments.
TRIGA® Research Test Reactors
TRIGA®—Advancing Research Through Safe, Proven Reactors
Deployed since the 1950s, General Atomics Electromagnetic Systems (GA-EMS) continues support the global fleet of TRIGA® test reactors with upgrades, consultations, and customer-driven enhancements.
Nuclear Engineering Services
Engineering the Future of Nuclear and Nuclear Waste
General Atomics Electromagnetic Systems (GA-EMS) is developing state-of-the-art technologies for nuclear reactor fuels, core components, and safe nuclear waste treatment and storage. Waste mitigation technologies reduce the cost and complexity of nuclear waste treatment by streamlining treatment methods and simplifying end-products.
