NANO Nuclear Files Six New Patent Applications Related to its Proprietary ZEUS™ Microreactor

NANO continues work to expand its intellectual property portfolio

New York, N.Y., May 30, 2025 (GLOBE NEWSWIRE) — NANO Nuclear Energy Inc. (NASDAQ: NNE) (“NANO Nuclear” or “the Company”), a leading advanced nuclear energy and technology company, today announced that it has filed six new utility patent applications with the United States Patent and Trademark Office (USPTO) related to its ZEUS™ microreactor.

ZEUS™ is being designed as a solid‑core battery reactor with a fully sealed core that uses a highly conductive moderator matrix to dissipate fission heat. As designed, there is no fluid inside the core, which lowers the risk typically associated in‑core coolant accident scenarios.

The ZEUS™ design calls for all reactor and support systems to fit within a standard shipping container, creating the potential for exceptional transportability to sites lacking conventional energy infrastructure. The unit is also designed to deliver thermal energy directly for heat applications or convert it to electricity, making it adaptable for a wide range of needs, including district heating, power generation and non‑electric uses such as hydrogen production.

“These patent applications for ZEUS reaffirm our commitment to strengthening NANO Nuclear’s intellectual property portfolio,” said Prof. Massimiliano Fratoni, Senior Director and Head of Reactor Design of NANO Nuclear. “The applications are directed towards safeguarding ZEUS’s key processes and components, which would not only benefit our own program but also contribute to progress across the entire advanced nuclear reactor industry.”

“We’re pleased to file these new patent applications, which reflect the hard and excellent work of our engineering and technical teams to advance our goal of bringing next‑generation microreactors, like ZEUS™, from development to commercialization,” said James Walker, Chief Executive Officer of NANO Nuclear.”

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 patented KRONOS MMR™ 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™, 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™ 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.
