RELIABLE ZERO-CARBON ENERGY ANYWHERE

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.

ADVANCED MANUFACTURING

MADE IN THE USA

Ultra Safe has initiated production of TRISO particles, FCM Fuel and core components for the MMR, with planned scaleup to large factories.

MILLIWATT to GIGAWATT

EARTH to SPACE

Ultra Safe Nuclear has the tech stack and capabilities to develop energy systems that meet a wide range of power and energy needs.

TRISO Particle Fuel

MADE IN THE USA

The most robust fuel form ever developed for nuclear reactors. Designed and manfuctured in the USA. It is now available to approved vendors.

NTP Engines

Nuclear Thermal Propulsion

More efficient engines that reduce space transport costs and enable new missions and capabilities for the space economy.

New Projects

Join the MMR Pipeline

With the help of our world-class EPC partners, we can deliver small and large projects worldwide sooner than other nuclear vendors. Achieving zero-carbon goals without disruption to industrial or commercial activities is now possible.
