GENERAL ATOMICS | ADVERTORIAL FEATURE From TRIGA®
FOR SEVENTY YEARS, GENERAL ATOMICS has helped define the evolution of nuclear technology. From the pioneering TRIGA® research reactor to today’s advanced terrestrial, defense, and space systems, the company continues to expand what nuclear energy can deliver. That spirit of innovation lives on at General Atomics Electromagnetic Systems (GA-EMS), where teams are developing resilient, long duration nuclear energy solutions for critical missions and the rapidly growing power demands of artificial intelligence. Engineers are creating the next generation of
nuclear materials, fuels, and reactor designs built to perform in the extreme environments of modern energy production, national security, and space exploration. The goal is to deliver systems that raise safety margins, boost performance, and operate for decades while providing reliable power wherever it is needed. To meet that need, the company developed SiGA®, a ceramic based fuel cladding engineered to avoid

melting and prevent chemical reactions that can occur between metal alloys and high temperature steam. This innovation increases efficiency, extends core life, and strengthens safety margins across a wide range of reactor concepts. Innovation is also accelerating in space nuclear power and propulsion, where solar energy fades in shadowed craters and distant orbits and chemical propulsion limits mission duration. Building on decades of nuclear experience, teams are advancing compact reactors, high temperature nuclear thermal propulsion fuels, and nuclear electric propulsion systems that deliver sustained power and efficient thrust for cislunar operations and future missions to the Moon and Mars. These systems enable reliable power, high efficiency propulsion, and long operational lifetimes for space outposts and deep space exploration. From TRIGA® to tomorrow’s reactors, GA EMS continues to redefine what nuclear energy can achieve.■
GA-EMS drives U.S. industrial innovation critical to producing next-generation technologies that support national security and economic competitiveness.
OVER 70 YEARS OF ADVANCING NUCLEAR From TRIGA®
to advanced gas cooled modular reactors,
microreactors for national security and critical infrastructure, and next generation terrestrial and space nuclear systems, General Atomics is engineering resilient, long duration energy for critical missions and the ever-increasing computing demands of AI.
Engineering That Endures — From TRIGA® to Tomorrow.
