The United States is pursuing an expanded and sustained presence beyond low Earth orbit, with near-term objectives focused on the Moon and longer-term ambitions extending to Mars. Achieving these objectives will require reliable, resilient power systems capable of supporting continuous operations in extreme and remote environments. Surface power is widely recognized as a foundational capability for enabling long-duration missions, permanent or semi-permanent infrastructure, and scalable exploration architectures.
These priorities align with a December 18, 2025 executive order titled “Ensuring American Space Superiority,” which calls for a human return to the lunar surface by 2028 and the establishment of initial elements of a permanent lunar outpost by 2030, while reaffirming development of a fission surface power (FSP) system as part of the long-term lunar architecture.
“The renewed global focus on nuclear energy has been encouraging, and the momentum being driven by the United States across the sector is clear,” said Jay Yu, Founder and Chairman of NANO Nuclear. “Through this RFI, NANO Nuclear is seeking to position itself to support national objectives beyond Earth’s orbit by evaluating the potential application of our patented LOKI MMR™ technology for extraterrestrial and lunar use cases. The responses received will help inform our long-term decision-making and provide a comprehensive assessment of the technical requirements, constraints, and opportunities as we plan our next steps.”
NASA, led by commercial and international partners, is advancing programs intended to transition space exploration from short-duration missions to sustained surface operations. As these efforts progress, there is growing emphasis on technologies that can operate independently of intermittent energy sources, reduce operational risk, and support a broad range of surface activities. Fission-based surface power systems represent the most scalable power solution to meet these needs.
NANO Nuclear’s space-relevant reactor design, the LOKI MMR™, is being developed through the Company’s subsidiary NANO Nuclear Space to address functional, operational, and architectural considerations publicly articulated for the FSP program. These considerations include continuous baseload power through extended lunar night or Martian winter, autonomous startup and shutdown, passive safety, launch and lander compatibility, modular interfaces, and integration with surface users and infrastructure.
“The LOKI MMR™ design is inherently well suited for space-based applications, enabling a straightforward pathway to address the specific operational needs of NASA,” said Florent Heidet, Ph.D., Chief Technology Officer and Head of Reactor Development of NANO Nuclear. “This RFI represents an important step for NANO Nuclear as we work to position the Company to support a stable, long-term program aligned with NASA’s and the Department of Energy’s objectives for space nuclear power. The LOKI MMR™’s form factor, robust safety characteristics, and power output profile make it well suited for integration into space operations, and we are pleased to take this next step through this RFI process.”
The LOKI MMR™ is designed to provide 300 kW to 1 MW of electrical power, scalable down to 100 kWe for space-based applications, with load-following capability. The patented system produces up to 3 MWth of thermal power, supports thermal offtake, and operates with reactor coolant temperatures ranging from 500 to 950°C. Electrical conversion efficiency is approximately 40 percent via a supercritical CO₂ Brayton cycle. The system utilizes helium and supercritical CO₂ as primary and secondary coolants and TRISO fuel enriched between 9.75 percent LEU and 19.9 percent HALEU. The fully integrated system mass is designed to be less than 15 metric tons, including shielding and power conversion components, and features a sealed, non-refueled core with a design life of up to 10 years of continuous operation.
“NANO Nuclear is developing its portfolio of advanced nuclear microreactor technologies with applications such as this in mind, positioning the LOKI MMR™ as a strong candidate for these use cases,” said James Walker, Chief Executive Officer of NANO Nuclear. “This Request for Information will help inform the next phase of development for our patented LOKI MMR™ and ensure our approach is aligned with the objectives of the U.S. Department of Energy and NASA as they evaluate the role of nuclear power in space-based applications, including lunar surface power. We welcome the opportunity to contribute to these efforts and to support the nation’s long-term space exploration and energy objectives.”
The objective of this RFI is to help shape NANO Nuclear’s planning and commercial partnership strategy by identifying organizations with enabling capabilities across areas such as systems integration, testing and qualification, manufacturing, deployment, and operations. The RFI will further be leveraged to inform NANO Nuclear’s plan for advancing the demonstration, integration, and maturation of surface fission power systems in alignment with NASA’s FSP objectives.
