We want to travel further and faster, grow and expand, live longer and better. Energy is the ultimate constraint on our human ambitions. We are loosening that constraint with advanced nuclear reactors and fuels providing zero-carbon power and heat.

Beating the Carbon Countdown



Ultra Safe Nuclear Corporation, a U.S. corporation headquartered in Seattle, is a global leader and vertical integrator of nuclear technologies and services, on Earth and in Space. Major initiatives include the Micro Modular Reactor (MMR®), Fully Ceramic Micro-encapsulated (FCM®) nuclear fuel, and nuclear power and propulsion technologies for space exploration. The company is demonstrating MMR Energy Systems at the Canadian Nuclear Laboratories with Ontario Power Generation and at the University of Illinois at Urbana-Champaign. New deployment projects underway in the United States, Canada, and Europe.

Ultra Safe Nuclear is committed to bringing safe, commercially competitive, clean and reliable nuclear energy to global power and industrial markets. Ultra Safe Nuclear is working with NASA and the Defense Department on advanced radioisotope power, nuclear thermal propulsion systems and advanced materials using the same strict inherent and intrinsic safety principles to drive innovation in fuels, materials, and design.

Ultra Safe Nuclear is the only private company producing TRISO and FCM fuel. This is enabling the transformation of key power and industrial sectors.


Develop, deploy and vertically integrate nuclear energy solutions, inclusive of hardware, fuel, execution and operational know how, that are safe and commercially competitive.


Reliable Zero-Carbon Energy Anywhere
