NANO Nuclear Holds Milestone Ceremony to Mark Beginning of Drilling Work for First KRONOS MMR™ Energy System in Partnership with University of Illinois

Tune in today via webcast at 11:30 am Eastern to hear from management, key commercial stakeholders, university officials and distinguished guests as NANO Nuclear celebrates the commencement of real-world work on its micro modular reactor prototype


NANO Nuclear Energy Inc. (NASDAQ: NNE) (“NANO Nuclear” or “the Company”), a leading advanced nuclear energy and technology company focused on developing clean energy solutions, today is holding a milestone ceremony at the University of Illinois Urbana-Champaign (U. of I.) for the research and commercial prototype of its flagship patented micro nuclear reactor, the KRONOS MMR Energy System.

A live webcast of the event will begin at 11:30 a.m. Eastern Time today and can be accessed via NANO Nuclear’s website at Events – NANO Nuclear Energy, with a replay of the event available on the same website for at least 30 days.

Highlighting the site characterization and geotechnical activities performed by global infrastructure leader AECOM, the ceremony will set the stage for the eventual construction, installation and operation of the KRONOS MMR at U. of I., where it will serve as an unprecedented real-world demonstration of the energy system and serve as a model for future university, government, and commercial deployments in North America and worldwide.

The event features remarks from:

  • Key NANO Nuclear executives, including NANO Nuclear’s Founder, Chairman of the Board and President, Jay Yu, Chief Executive Officer and Board Member James Walker, Chief Technical Officer and Head of Reactor Development Florent Heidet, Ph.D., focusing on the company’s differentiated strategy and an overview of the compelling value proposition of its KRONOS MMR; and
  • Remarks from NANO Nuclear Executive Advisory Board Members Retired Vice Admiral Charles J. Leidig Jr. and Retired 4-Star U.S. Army General who served as the Supreme Allied Commander Europe (SACEUR) for NATO Forces General Wesley K. Clark, highlighting the need for advanced nuclear solutions such as the KRONOS MMR for military applications and next generation microgrid infrastructure.

The event will also feature remarks from:

  • University of Illinois leadership, including project engineers from the university’s world-renowned Grainger College of Engineering, focusing on the importance of the project to the university, the U. of I.’s key technical capabilities, and expected areas of support;
  • Prominent engineering, procurement, and construction management and construction firms, Hatch and PCL, demonstrating strong interest in the KRONOS MMR project from established leaders in the nuclear and infrastructure industries;
  • A multi-industry infrastructure and manufacturing company exploring the KRONOS MMR as a potential solution for its energy needs; and
  • An accomplished executive specializing in data-center development and high-reliability infrastructure discussing key advantages of advanced nuclear solutions in addressing the complex power demands of the data-center industry.

“Today’s ceremony and presentations marking the commencement of drilling work on our prototype KRONOS MMR at U. of I. are not only a celebration, but a demonstration of our accomplishments in translating years of design and research into real-world progress,” said Jay Yu, Founder, Chairman of the Board and President of NANO Nuclear. “This milestone shows our investors and the public that our work in just a year and half since becoming a public company is moving from concept to reality with the support of the University of Illinois Urbana-Champaign, a leading nuclear research institution in North America, as well as a growing number of industry stakeholders. The site’s development marks a critical phase in advancing our prototype toward construction, demonstration, regulatory licensing and ultimate commercial deployment, reinforcing our leading role in the development and rollout of the next generation of resilient, microreactor solutions.”

Developed to meet the growing demand for resilient, modular, and clean energy solutions for artificial intelligence and data centers, industrial projects, military applications, remote communities, and other commercial applications, the KRONOS MMR is a stationary, high-temperature gas-cooled microreactor designed to deliver 15 MWe (45 MWth) of carbon-free power, for multi-decade use across multiple industries and environments. Multiple KRONOS MMRs can be synergistically used to achieve any desired power level. Using meltdown-resistant TRISO fuel and passive helium cooling, the KRONOS MMR is being designed to shut down and remain in a safe state automatically without any human intervention or external power (so called “walk-away safety”) while seeking to ensure the ability to disconnect from the main grid and operate autonomously during outages or other disruptions (so called “full island-mode microgrid” capability).

“The start of physical work at the University of Illinois Urbana-Champaign is a defining moment for our engineering and regulatory teams and a great opportunity to bring together a wide array of supporters to begin showcasing how our next-generation microreactor technology, the KRONOS MMR™, can strengthen U.S. energy sovereignty and modernize the nation’s clean power infrastructure,” said James Walker, Chief Executive Officer of NANO Nuclear. “Together with the University of Illinois Urbana-Champaign, AECOM, the State of Illinois, and expected key strategic partners, we are laying the foundation for pivotal nuclear microreactor technologies that can help secure the nation’s energy future.”

“This ceremony reflects the continued efforts of our engineering and scientific teams in advancing our novel KRONOS MMR Energy System towards construction and the growing support for NANO Nuclear from various stakeholders,” said Florent Heidet, Ph.D., Chief Technology Officer and Head of Reactor Development of NANO Nuclear. “With this event, we are demonstrating that advanced nuclear energy can be developed responsibly, efficiently, and in alignment with North America’s long-term goals for energy security, resilience, and sustainability.”

Using the geotechnical data from AECOM’s site characterization and drilling activities, NANO Nuclear plans to submit a construction permit application for the KRONOS MMR Energy System in or around the first quarter of 2026.
