NANO Nuclear Energy Inc. (NNE) soared 5.18% in pre-market trading on Wednesday following a significant announcement regarding its advanced nuclear microreactor project.

The surge comes after the company announced that the U.S. Nuclear Regulatory Commission has formally accepted the Construction Permit Application for the deployment of its proprietary KRONOS MMR™ microreactor at the University of Illinois Urbana-Champaign. This acceptance initiates the NRC's formal safety, environmental, and technical review process, marking a crucial regulatory step forward for the project.

The milestone solidifies the KRONOS MMR™ system as the first commercially-ready microreactor to reach this stage in the U.S. NRC's licensing process. Based on the company's current understanding, the formal review is estimated to be completed in 2027, potentially allowing nuclear construction activities to begin in the second half of that year. This advancement reinforces the company's strategy of accelerating commercialization through early regulatory engagement and engineering partnerships.
