These advantages position us with a high degree of design maturity, underpinning our ability to progress toward construction and commercialization. Our strong technical foundation was further validated by the submission of a Construction Permit Application to the U.S. NRC by the University of Illinois for our KRONOS MMR™ deployment on the university’s campus, making NANO Nuclear the first commercially-ready microreactor developer to reach this critical stage. We pair this strong foundation with a focus on vertical integration across critical aspects of the nuclear fuel cycle, which we expect to provide an advantage versus our competitors, positioning us to accelerate reactor deployment, enhance the long-term economics of our reactors, and benefit as a key supplier to the industry,” said Jay Yu, Founder and Chairman of NANO Nuclear.

“We’ve recently outlined four potential catalysts offering the opportunity to create shareholder value: regulatory advancement, commercial progress, expanding our vertical integration across the nuclear fuel supply chain, and strategic partnerships—and we made strong progress in each area during our second quarter. As we look ahead, we expect further progress in each of these areas to unlock additional shareholder value while strengthening our competitive position.”
