NANO Nuclear Acquires 23,537-Square-Foot Demonstration And Office Facility On 2.75 Acres Of Land In Oak Brook, Illinois To Support The Development Of The KRONOS MMR Microreactor Energy System

(MENAFN- Newsfile Corp) New York, New York--(Newsfile Corp. - July 30, 2025) - 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 announced that it has acquired a 2.75-acre land and building package in Oak Brook, Illinois to serve as a regional demonstration and office facility to support the development of NANO Nuclear's lead development project - the KRONOS MMRTM Microreactor Energy System - in collaboration with the University of Illinois Urbana-Champaign (UIUC) on its campus grounds.

The $3.5 million purchase includes a 23,537-square-foot stand-alone building facility, including a 7,400-square-foot non-nuclear demonstration area. The facility will also initially house up to 60 nuclear engineers, researchers and support staff to engage in component construction and testing for the KRONOS MMRTM, a high technology readiness level (TRL), cutting edge, stationary, advanced micro modular reactor. It will also serve as a base of operations to collaborate with UIUC on the construction and regulatory licensing of the KRONOS MMRTM.

This announcement comes on the heels of NANO Nuclear announcing the engagement of AECOM, the trusted global infrastructure leader, under a master services agreement to support site-specific engineering, environmental analysis and regulatory planning at UIUC. The agreement lays the groundwork for site-specific engineering in preparation for deploying the first MMRTM at UIUC, a globally recognized hub for nuclear research and innovation. Planned activities include detailed environmental reviews, regulatory pathway planning, and site drilling to obtain the geological data required for submitting a construction permit application to the U.S. Nuclear Regulatory Commission (NRC).

The Oak Brook Facility is NANO Nuclear's third U.S facility and second U.S. site dedicated to physical test work, joining the Company's facility in Westchester County, New York.

"This new facility will be the hub for NANO Nuclear's work on our lead microreactor project, the KRONOS MMRTM energy system. It will strengthen our collaboration with the University of Illinois and help us advance the KRONOS MMR towards construction, demonstration, regulatory licensing and ultimate deployment," said Jay Yu, Founder and Chairman of NANO Nuclear. "Establishing a local facility was essential to supporting the KRONOS MMRTM program. This expansion, alongside our active recruitment drive for nuclear engineers and researchers to join our efforts at this facility, reflects our growing presence in the advanced nuclear energy sector and broadens our reach across the northern United States and into Canada."

In 2023, Illinois generated 54.89% of its electricity from nuclear power and accounted for 13% of the nation's total nuclear output, according to the U.S. Energy Information Administration. The state's established infrastructure and supportive political and social environments make Illinois an ideal location for advancing next-generation reactor technologies like NANO Nuclear's KRONOS MMRTM.

NANO Nuclear has already begun site-specific engineering work and contracting with key vendors to support the KRONOS MMRTM project. The new facility's location near the U.S.-Canada border also positions NANO Nuclear to advance its existing plans to bring the KRONOS MMRTM to Canada and prepare for construction, testing, regulatory licensing and ultimately commercialization efforts across North America.

"We are very pleased to finalize the acquisition of this property in Oak Brook," said James Walker, Chief Executive Officer of NANO Nuclear. "This facility will serve as our central hub for building the KRONOS MMRTM Energy System on the UIUC campus, an effort that would mark the first commercial microreactor developed at a U.S. university and position us as a leader in this sector. Illinois has a proud nuclear history, and UIUC is a major driver of innovation and testing in nuclear energy. We're excited to establish our presence in Illinois as we continue to advance our goals and drive value for our shareholders."

About NANO Nuclear Energy Inc.

NANO Nuclear Energy Inc. (NASDAQ: NNE) is an advanced technology-driven nuclear energy company seeking to become a commercially focused, diversified, and vertically integrated company across five business lines: (i) cutting edge portable and other microreactor technologies, (ii) nuclear fuel fabrication, (iii) nuclear fuel transportation, (iv) nuclear applications for space and (v) nuclear industry consulting services. NANO Nuclear believes it is the first portable nuclear microreactor company to be listed publicly in the U.S.

Led by a world-class nuclear engineering team, NANO Nuclear's reactor products in development include the patented KRONOS MMR ^TM Energy System , a stationary high-temperature gas-cooled reactor that is in construction permit pre-application engagement U.S. Nuclear Regulatory Commission (NRC) in collaboration with University of Illinois Urbana-Champaign (U. of I.), " ZEUS" , a solid core battery reactor, and " ODIN" , a low-pressure coolant reactor, and the space focused, portable LOKI MMR ^TM , each representing advanced developments in clean energy solutions that are portable, on-demand capable, advanced nuclear microreactors.

Advanced Fuel Transportation Inc. (AFT) , a NANO Nuclear subsidiary, is led by former executives from the largest transportation company in the world aiming to build a North American transportation company that will provide commercial quantities of HALEU fuel to small modular reactors, microreactor companies, national laboratories, military, and DOE programs. Through NANO Nuclear, AFT is the exclusive licensee of a patented high-capacity HALEU fuel transportation basket developed by three major U.S. national nuclear laboratories and funded by the Department of Energy. Assuming development and commercialization, AFT is expected to form part of the only vertically integrated nuclear fuel business of its kind in North America.

HALEU Energy Fuel Inc. (HEF) , a NANO Nuclear subsidiary, is focusing on the future development of a domestic source for a High-Assay, Low-Enriched Uranium (HALEU) fuel fabrication pipeline for NANO Nuclear's own microreactors as well as the broader advanced nuclear reactor industry.

NANO Nuclear Space Inc. (NNS) , a NANO Nuclear subsidiary, is exploring the potential commercial applications of NANO Nuclear's developing micronuclear reactor technology in space. NNS is focusing on applications such as the LOKI MMR ^TM system and other power systems for extraterrestrial projects and human sustaining environments, and potentially propulsion technology for long haul space missions. NNS' initial focus will be on cis-lunar applications, referring to uses in the space region extending from Earth to the area surrounding the Moon's surface.
