NANO Nuclear Energy Inc. (NASDAQ: NNE) has signed a 10-year Cooperative Research and Development Agreement (CRADA) with the U.S. Department of Energy’s Idaho National Laboratory (INL), marking a significant milestone in the company’s mission to develop and commercialize its advanced microreactor technologies. The agreement is expected to accelerate testing, regulatory engagement, and commercial readiness for the company’s stationary KRONOS MMR and portable LOKI MMR reactor systems.
The announcement positions the emerging nuclear energy company to align more closely with federal energy goals and capitalize on rising demand for compact, resilient, and clean energy systems designed for off-grid and space applications.
How does the CRADA with Idaho National Laboratory strengthen Nano Nuclear’s reactor deployment plans?
The long-term CRADA will allow NANO Nuclear Energy to tap into INL’s advanced nuclear facilities and domain expertise to support multiple phases of microreactor development. This includes design validation, materials qualification, simulation modeling, safety case development, licensing support, and site readiness assessments.
INL’s experience in nuclear engineering, high-temperature gas-cooled reactor design, and irradiation testing is widely regarded as best-in-class. The laboratory’s infrastructure will help de-risk many of the technical and regulatory uncertainties typically associated with new reactor designs, especially in early-stage commercialization.
James Walker, Chief Executive Officer of NANO Nuclear Energy, described the agreement as a transformative milestone, enabling the company to enter the next phase of technical and institutional maturity. He noted that access to INL’s resources would enhance NANO Nuclear’s ability to bring its next-generation reactor technologies to market both in the U.S. and internationally.
What microreactor technologies are being developed by Nano Nuclear Energy under this agreement?
The CRADA will support the advancement of both the KRONOS MMR and the LOKI MMR, which are at the center of NANO Nuclear’s product roadmap. The KRONOS MMR is a stationary high-temperature gas-cooled microreactor designed for long-duration, high-efficiency power generation. It is currently undergoing pre-application engagement with the U.S. Nuclear Regulatory Commission (NRC), in collaboration with the University of Illinois Urbana-Champaign.
In contrast, the LOKI MMR is a portable micronuclear reactor intended for flexible deployment in remote, mobile, or space-constrained environments. The system targets a wide range of applications from military installations and disaster relief sites to off-grid data centers and extraterrestrial bases.
Both reactor types are designed for modular deployment and feature passive safety, minimal maintenance, and scalable output. These attributes align well with growing energy demands from emerging industries such as artificial intelligence infrastructure, autonomous logistics, and long-duration spaceflight.
Florent Heidet, Ph.D., Chief Technology Officer at NANO Nuclear, highlighted that INL’s leadership in high-temperature gas reactor technologies over the past several decades makes it an ideal partner. He emphasized that the collaboration would enhance the reliability and simplicity of the company’s reactor systems.
What support will Nano Nuclear receive from INL throughout the lifecycle of its microreactors?
Under the CRADA, NANO Nuclear Energy will benefit from a structured ecosystem of support that spans the full microreactor lifecycle—from early conceptual design to final decommissioning planning.
Key deliverables from INL include advanced irradiation environments to test new materials and fuels, digital twin simulations to refine reactor dynamics, and compliance advisory to meet NRC and DOE safety requirements. Additionally, INL will support the engineering and quality assurance frameworks necessary for eventual siting and deployment.
The collaboration is expected to position NANO Nuclear as a credible U.S.-based player capable of addressing both government and commercial clean energy needs through distributed nuclear generation.
The CRADA also opens doors to further strategic engagements, including possible siting of a demonstration unit at INL’s facilities or additional DOE funding opportunities as the microreactor market expands.
How is Nano Nuclear building a vertically integrated ecosystem around HALEU fuel and nuclear logistics?
Alongside its reactor portfolio, NANO Nuclear Energy is building an integrated nuclear fuel and logistics supply chain to support deployment at scale. Through its subsidiary HALEU Energy Fuel Inc. (HEF), the company is developing a domestic pipeline for High-Assay, Low-Enriched Uranium (HALEU) fuel fabrication. HALEU is critical for advanced reactors and is in limited commercial supply globally.
The company’s logistics arm, Advanced Fuel Transportation Inc. (AFT), holds an exclusive license to a patented HALEU transport basket developed by three U.S. national laboratories with Department of Energy funding. AFT aims to build a commercial transportation network capable of delivering HALEU to SMR developers, defense programs, and national labs.
Together, HEF and AFT form the backbone of what NANO Nuclear hopes will become North America’s only fully integrated microreactor ecosystem, combining reactor deployment, fuel sourcing, and nuclear logistics within a single corporate structure.
How does Nano Nuclear’s space-focused strategy align with U.S. ambitions for extraterrestrial power systems?
The company is also extending its technology roadmap into the space sector through NANO Nuclear Space Inc. (NNS). This subsidiary is focused on adapting the LOKI MMR and other proprietary designs for cis-lunar missions, lunar habitats, and future Martian operations.
NNS’s initial development priorities include compact nuclear power systems for human-sustaining environments and surface-based energy generation for lunar installations. Over the longer term, the company is exploring nuclear propulsion concepts for deep space exploration, aligning with NASA and Department of Defense interests in nuclear thermal propulsion and space-based nuclear reactors.
This space-focused pivot diversifies NANO Nuclear’s addressable market and adds a speculative but high-upside dimension to its commercial strategy. Analysts have noted that interest in space-based nuclear power has surged following NASA’s Artemis program and broader geopolitical interest in Moon and Mars operations.
What are institutional investors and analysts watching following the DOE agreement?
Analysts and institutional investors have generally interpreted the CRADA announcement as a meaningful credibility marker for NANO Nuclear Energy, which only recently went public as the first listed microreactor-focused company in the U.S. nuclear sector. The deal signals alignment with U.S. federal priorities and reduces perceived regulatory and technology risks.
Market watchers are closely monitoring several upcoming milestones that could shape the future trajectory of NANO Nuclear Energy Inc. Among the key developments being tracked are the pace of licensing progress with the U.S. Nuclear Regulatory Commission (NRC) for the KRONOS MMR™, as well as potential field testing or pilot deployments at Idaho National Laboratory (INL) or affiliated U.S. Department of Energy (DOE) facilities. Investors are also paying close attention to capital formation initiatives that would support reactor manufacturing and first-of-a-kind demonstration, alongside regulatory clarity regarding HALEU fuel sourcing and transport licensing. Additionally, any commercial agreements struck with government agencies or hyperscale datacenter operators are expected to serve as strong indicators of market confidence and commercial readiness.
Analysts believe that successful delivery on even one of these fronts could significantly rerate NANO Nuclear’s growth trajectory, especially as institutional investors look to diversify exposure into non-carbon baseload energy assets.
How does this agreement reflect broader trends in the nuclear microreactor market?
The CRADA announcement comes amid growing interest in microreactors as viable energy solutions for defense, disaster recovery, Arctic infrastructure, and industrial decarbonization. With the passage of the ADVANCE Act and the May 2025 U.S. executive orders supporting domestic nuclear innovation, companies like NANO Nuclear stand to benefit from a more supportive regulatory and funding environment.
As traditional grids face growing stress from extreme weather, AI power demands, and geopolitics, the case for compact, reliable, and transportable nuclear systems is strengthening. If NANO Nuclear can demonstrate technical maturity and fuel readiness, it may be well-positioned to capture first-mover advantage in several niche but high-value segments.
