The CPA was submitted to the NRC on March 31, 2026 by the U. of I., NANO Nuclear's partner for the planned full-scale KRONOS MMR™ reactor at the university. Acceptance of the CPA signifies the application contains sufficient information for the NRC to begin its formal safety, environmental, and technical review process. The original submission and the NRC's formal acceptance represent a major advancement toward construction, licensing and deployment of the KRONOS MMR™ system.
The KRONOS MMR™ system is now among a small group of Generation IV advanced nuclear reactors, and the Company believes, the first commercially-ready microreactor to progress to the CPA stage of the U.S. NRC's formal licensing process. Based on NANO Nuclear's current understanding of the anticipated scope and review process, the Company estimates the NRC formal review will be completed in 2027, providing the opportunity for NANO Nuclear to begin nuclear construction activities at the U. of I. in the second half of 2027.
NANO Nuclear believes this milestone further reinforces the KRONOS MMR™'s position among advanced microreactor programs progressing through U.S. regulatory pathways and highlights the Company's broader strategy of accelerating commercialization through early regulatory engagement, engineering advancement, and partnerships.
