NANO Nuclear and MIT's Department of Nuclear Science and Engineering Launch Advanced Irradiation Study to Investigate Salt-Based Thermal Storage for Nuclear Applications

New York, N.Y., May 20, 2025 (GLOBE NEWSWIRE) -- NANO Nuclear Energy Inc. (NASDAQ:NNE) ("NANO Nuclear" or the "Company"), a leading advanced nuclear technology and energy company, today announced the launch of a major irradiation testing program in collaboration with the Massachusetts Institute of Technology (MIT) Department of Nuclear Science and Engineering. The two-year collaboration will investigate the thermal and radiolytic behavior of nitrate molten salts, commonly referred to as "solar salts", to assess their viability in advanced nuclear energy systems for thermal energy storage and cooling applications.

Funded by NANO Nuclear through over $500,000 of research and development investment, the work will be conducted under the supervision of Prof. Koroush Shirvan, Principal Investigator and a leading expert in nuclear systems engineering. The research will focus on the of salt materials subjected to gamma irradiation using MIT's Gammacell 220F Co-60 irradiator—ensuring a safe, precisely controlled, and highly instrumented test environment.

"We are proud to support this world-class irradiation study at MIT," said Jay Yu, Founder and Chairman of NANO Nuclear. "Understanding how molten salts perform under radiation is essential to unlocking next-generation reactor designs, and this facility gives us the capabilities to do that without the use of any nuclear materials."

While molten nitrate salts are widely used in solar thermal energy systems, the knowledge of these materials' behavior under the ionizing radiation conditions representative of nuclear environments is relatively scarce. This collaboration aims to fill that critical knowledge gap by assessing both the chemical and thermophysical performance of the salts during and after irradiation.

Using a suite of cutting-edge diagnostics, including a magnetic sector residual gas analyzer (RGA), laser flash analysis, and post-irradiation spectroscopic techniques, MIT researchers will measure off-gassing behavior, thermal degradation, and long-term material stability. The results will inform system design for microreactors that utilize molten salts for heat transfer or energy storage, improving the accuracy and reliability of safety and performance models.

"This project offers an exciting opportunity to characterize molten nitrate salts in radiation environments with a level of precision not previously achieved," said Dr. Koroush Shirvan, Principal Investigator at MIT. "We're using real-time diagnostics, high-temperature test rigs, and modern analytical techniques to generate data that can have immediate impact on next-generation reactor development."

The results of this study will feed directly into the engineering and design processes and could also prove useful for other clean energy applications, including industrial process heat and off-grid energy storage.

"We are thrilled to see this groundbreaking research move forward with MIT," said Professor Ian Farnan, Lead of Nuclear Fuel Cycle, Radiation and Materials of NANO Nuclear. "The ability to assess salt performance in radiation fields without reliance on operating reactor gives us unprecedented flexibility and speed in advancing the development of our reactor systems."

The project is expected to conclude in 2027, with quarterly updates and final data delivery coordinated between MIT and NANO Nuclear's engineering teams. As NANO Nuclear continues to expand its operations, the Company remains committed to developing cutting-edge nuclear solutions that redefine the global energy landscape.

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.
