Nano Nuclear Energy’s KRONOS microreactor becomes the first commercial advanced reactor to reach this regulatory milestone.
The U.S. Nuclear Regulatory Commission formally accepted Nano Nuclear Energy’s (NNE) Construction Permit Application for its KRONOS micro modular reactor. This marks the first time a commercial advanced microreactor has reached this stage of regulatory review.
The KRONOS reactor, a high-temperature gas-cooled microreactor, is designed for off-grid use by data centers and industrial operators. The NRC’s acceptance indicates the application contains sufficient data for further evaluation, though the company still faces a rigorous regulatory process.
Nano Nuclear plans to build its first prototype at the University of Illinois Urbana-Champaign. The company’s progress reflects growing interest in advanced nuclear technologies amid a broader industry resurgence.
