NANO Nuclear’s KRONOS MMR Microreactor Advances to Critical Milestone Toward Reactor Deployment with the University of Illinois Urbana-Champaign Submission of a Construction Permit Application to the U.S. Nuclear Regulatory Commission
NANO Nuclear Energy Inc. announced that a Construction Permit Application (CPA) has been submitted to the U.S. Nuclear Regulatory Commission (NRC) for its KRONOS MMR microreactor. The CPA was formally submitted by The Grainger College of Engineering at the University of Illinois Urbana-Champaign (U. of I.), NANO Nuclear’s partner for the KRONOS MMR deployment at the U. of I. With this submission, NANO Nuclear becomes the first commercially-ready microreactor developer and the third commercially-ready Generation IV advanced reactor developer to submit a CPA, placing NANO Nuclear among a small group of advanced nuclear companies progressing toward commercial deployment. The CPA submission represents the achievement of a critical milestone for the KRONOS MMR on the pathway from engineering design, to construction on the campus of the U. of I., to reactor licensing, to ultimate commercial deployment. The CPA represents one of the most consequential milestones in the nuclear reactor development lifecycle. Unlike early-stage conceptual work, a CPA requires: Advanced engineering and safety analysis; Site-specific evaluation and environmental considerations; Demonstration of compliance with NRC regulatory frameworks; Extensive documentation developed through ongoing engagement with NRC staff. This process is not undertaken in isolation – developers typically engage in pre-application interactions and iterative feedback with the NRC, meaning that a CPA submission reflects years of technical refinement and regulatory alignment. The preparation of a CPA represents the culmination of years of engineering development, thousands of pages of technical documentation, coordinated input across reactor design, safety analysis, environmental review, and regulatory compliance disciplines, and establishment of a viable supply chain. In NANO Nuclear’s partnership with the U. of I., the CPA submission builds on an extensive body of work developed through continuous engagement with the NRC, including completion of the readiness assessment, a voluntary but highly rigorous process aimed at ensuring a complete and high-quality application. This iterative process reflects a high level of alignment with regulatory expectations and provides strong confidence in the application’s readiness for acceptance for docketing and formal NRC review. By advancing to the CPA stage, NANO Nuclear is now firmly positioned as: An execution-focused microreactor developer; A company progressing toward construction and demonstration of a commercially ready reactor over the next few years; One of the few advanced reactor companies moving through formal NRC licensing. This milestone signals that the intellectual property protected KRONOS MMR reactor is no longer just a design, but an energy system being actively moved into construction, licensing, and eventual commercial deployment at scale. Unlike many advanced reactor concepts focused on limited research and development demonstration, NANO Nuclear’s approach with the KRONOS MMR is centered on commercially ready, scalable systems designed for real-world applications from the outset. NANO Nuclear believes the KRONOS MMR CPA submission represents one of the only full-scale, deployment-oriented reactor applications among its peer group, reflecting a strategy focused not just on proving technology, but on building repeatable, commercially viable systems. This approach directly supports NANO Nuclear’s broader vision of: Regulatory approval of a standardized commercial power reactor; Standardized reactor manufacturing; Fleet-scale rollout across multiple markets. Insights gained through the CPA process are expected to play a critical role in refining NANO Nuclear’s assembly, siting, and deployment strategies, enabling the Company to move efficiently through future licensing and through multi-unit deployment projects. Following acceptance of the CPA for review, the NRC will begin its formal evaluation process, including safety and environmental assessments. Based on NANO Nuclear’s current understanding of the anticipated scope and review process, the company estimates the NRC formal review period to take approximately 12 months. The review period represents the next phase in NANO Nuclear’s journey toward: Construction authorization; Reactor operation; Commercial licensing; Fleet-scale deployment at scale. With global demand for clean, reliable baseload power accelerating – driven by artificial intelligence, electrification, and industrial decarbonization – the timing of this milestone is particularly significant. Developers capable of navigating the regulatory process today are expected to be well-positioned to deploy reactors in the years to come. NANO Nuclear’s KRONOS MMR design advancement to the CPA stage signals not only technical maturity, but also the ability to move at the pace required to capture first-mover advantage in a rapidly tightening energy market.
