Former Head of Engineering at Ultra Safe Nuclear Corp. brings firsthand knowledge of recently acquired advanced reactor technologies and extensive reactor building experience

New York, N.Y., March 07, 2025 (GLOBE NEWSWIRE) -- 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 Florent Heidet, Ph.D. has joined NANO Nuclear as its Chief Technology Officer and Head of Reactor Development.

Dr. Heidet is a world-renowned expert on advanced nuclear reactor technologies, leveraging two decades of nuclear engineering and project management expertise. Dr. Heidet was previously the Head of Engineering at Ultra Safe Nuclear Corp. (USNC), where he led a multidisciplinary team of over 100 experts working around the globe to advance the development of the KRONOS MMR^TM Energy System and LOKI MMR^TM technologies prior to their acquisition by NANO Nuclear earlier this year.

Prior to his leadership role with USNC, Dr. Heidet spent 12 years at Argonne National Laboratory, where he played a central role in most of the laboratory’s reactor design projects. He led the design of the Versatile Test Reactor, a $2 billion program under the auspices of the U.S. Department of Energy, served as the Argonne manager for the Transformational Challenge Reactor program, coordinated the Nuclear Thermal Propulsion efforts in support of NASA, and provided expertise and leadership to numerous federal, commercial, and international projects.

Dr. Heidet will be primarily responsible for advancing all of NANO Nuclear’s reactor projects and will have general oversight of all the Company’s various other technologies in development. His decades of experience and status as an innovator in the nuclear energy industry will be invaluable to NANO Nuclear as it seeks to position itself as a global leader in advanced nuclear energy solutions. He will report to both James Walker, NANO Nuclear’s Chief Executive Officer, and Jay Yu, NANO Nuclear’s Chairman and President. Mr. Walker is relinquishing the position of NANO Nuclear’s Head of Reactor Development to accommodate the hiring of Dr. Heidet.

“I am very proud to join the NANO Nuclear team, and I plan to hit the ground running and play a leading role in the development of our innovative suite of nuclear reactor and related technologies,” said Dr. Florent Heidet, Chief Technology Officer and Head of Reactor Development of NANO Nuclear Energy. “The management and technical teams at NANO Nuclear have proven themselves to be innovators with the development of proprietary microreactor systems like ODIN and ZEUS, and it is a pleasure to continue my work on the KRONOS MMR^TM and LOKI MMR^TM systems alongside them. I’ve had the opportunity to examine the several microreactor technologies being developed in the marketplace, and I believe NANO Nuclear is the ideal home for the KRONOS MMR^TM and LOKI MMR^TM. I am dedicated to seeing the development of all of NANO Nuclear reactor designs, as well as its other innovative technologies, from testing, to regulatory approvals and through to commercialization.”
