<div id="readability-page-1"><div>Nano Nuclear submitted a Construction Permit Application (CPA) to the U.S. Nuclear Regulatory Commission (NRC) for their Kronos microreactor project at the University of Illinois. The filing marks the latest step in a project we’ve tracked since site characterization began last fall.<blockquote>Watch: Modular Energy Pioneer Nano Nuclear Begins Drilling First Reactor In Illinois https://t.co/hUcFvtXfaD— zerohedge (@zerohedge) October 24, 2025</blockquote>Kronos is a high-temperature gas-cooled reactor (HTGR) engineered for commercial deployment. It delivers 15 megawatts of carbon-free baseload power using meltdown-resistant TRISO fuel and helium coolant. The design emphasizes walk-away safety, autonomous operation during grid outages, and scalability through multiple units. Intended uses include powering artificial intelligence data centers, industrial electrification, military bases, and remote communities.Nano Nuclear acquired the technology in 2024 from Ultra Safe Nuclear Corp. and positioned it as one of the first commercially ready microreactor platforms.<img width="500" height="312" src="https://imageproxy.pbkrs.com/https://www.zerohedge.com/_next/image/query-cT03NSZ1cmw9aHR0cHM6Ly9hc3NldHMuemVyb2hlZGdlLmNvbS9zM2ZzLXB1YmxpYy9pbmxpbmUtaW1hZ2VzL2ltYWdlMi5qcGVnJnc9MTkyMA?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" original-src="https://imageproxy.pbkrs.com/https://www.zerohedge.com/_next/image/query-cT03NSZ1cmw9aHR0cHM6Ly9hc3NldHMuemVyb2hlZGdlLmNvbS9zM2ZzLXB1YmxpYy9pbmxpbmUtaW1hZ2VzL2ltYWdlMi5qcGVnJnc9MTkyMA"/>The University of Illinois partnership targets the first full-scale Kronos research reactor deployment. We detailed the October 2025 launch of geotechnical drilling and site characterization work, followed by a ceremonial groundbreaking. Those steps built on state support from Illinois Governor J.B. Pritzker and positioned the campus project as the lead effort in Nano’s broader commercialization roadmap. The company has since expanded discussions for additional deployments in Texas, South Korea, and at U.S. federal sites.Under the NRC process, staff will first review the application package for completeness and docketing. Once accepted, the agency will conduct a formal technical and environmental evaluation. Nano estimates this formal review phase will take approximately 12 months, after which the NRC could authorize construction. The timeline aligns with recent agency efforts to streamline advanced reactor licensing while maintaining rigorous safety standards.Company executives described the submission as validation of years of engineering and pre-application engagement. Chief Technical Officer Florent Heidet called it “a defining moment” that separates ready projects from those still in early development.The milestone keeps Nano on track for initial test operations at Illinois by the late 2020s and supports its goal of factory-built, fleet-scale microreactor production.</div></div>

Nano Nuclear has submitted a Construction Permit Application to the U.S. Nuclear Regulatory Commission for its Kronos microreactor project at the University of Illinois. The Kronos reactor, designed for commercial use, will provide 15 megawatts of carbon-free power and emphasizes safety and scalability. This submission is seen as a significant milestone for Nano Nuclear, with plans for initial test operations by the late 2020s. The project has garnered state support and aims for further deployments in Texas, South Korea, and federal sites.
