We will provide hardware and services for reliable energy anywhere – on Earth and in Space. Developed since 2015, MMR is now becoming reality – the first in a family of hardware and service products for reliable energy anywhere. We are further utilizing our design, licensing, and technology capabilities, such as ceramic additive manufacturing and proprietary sintering techniques, to develop nuclear power systems for advanced applications on earth and in space. These include Transportable Power Units, Nuclear Thermal Propulsion and Lunar Surface Power systems.

Ultra Safe Nuclear is a 200+ employee technology company, well balanced between design, licensing, manufacture and project development, with a mix of young and senior engineers, material scientists and business experts, and a well-established network of suppliers and high-quality partnerships. We have a “best in business” workforce that is highly motivated, well tested and demonstrably capable of meeting tough development and commercial milestones. We are able to recruit competitively in all areas of operations in multiple countries.


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


Secure and reliable energy on earth and beyond that is safer, simpler, cleaner and more versatile than today's technologies.


We will engage with and support our employees, contractors, vendors, clients, business partners, and our host communities to uphold and embrace these values:

  • Safety: We will protect the public, our people and the environment from harm from our activities or products. 
  • Quality: We will develop a superior product that meets the requirements of our clients and communities. 
  • Efficiency: We will build on experience and use the latest technological tools to create value and deliver the best products and outcomes.
  • Character: We will treat each other with fairness, respect, care and honesty.
  • Cooperation: We will excel individually and together in everything we do. We will achieve greatness through cooperation.
