NANO Nuclear Energy Inc. reported that the U.S. Nuclear Regulatory Commission has formally accepted the Construction Permit Application for deployment of its KRONOS MMR™ microreactor at the University of Illinois Urbana-Champaign. This acceptance means the application contains enough detail for the NRC to begin its full safety, environmental, and technical review.
The Construction Permit Application was submitted on March 31, 2026 by the university, NANO Nuclear’s partner for the planned full-scale KRONOS MMR™ reactor. Based on its current understanding of the process, the company estimates the NRC review could be completed in 2027, creating an opportunity to start nuclear construction activities at the university in the second half of 2027. Management describes this as a major advancement toward construction, licensing, and deployment and believes KRONOS MMR™ is the first commercially-ready microreactor to reach this stage in the U.S. licensing process.
NANO Nuclear Energy Inc. reported its second quarter fiscal year 2026 results and shared a broad business update centered on its KRONOS MMR™ microreactor program and nuclear fuel strategy. The company highlighted progress as a North American microreactor developer during the quarter ended March 31, 2026 and afterward.
University of Illinois submitted a Construction Permit Application to the U.S. Nuclear Regulatory Commission for a full-scale KRONOS MMR™ system on its campus, described as a major step toward construction readiness. Management also emphasized efforts to build a vertically integrated fuel cycle, including transport and HALEU fuel fabrication businesses and space-focused applications.
The company scheduled a webcast for May 14, 2026 at 5:00 p.m. Eastern to discuss the quarter’s developments and future plans.
NANO Nuclear Energy Inc. reported that it has been awarded a U.S. Department of Energy Gateway for Accelerated Innovations in Nuclear (GAIN) voucher, NE-26-38854, for its KRONOS MMR™ Energy System. The voucher supports collaboration with Oak Ridge National Laboratory to apply ORNL’s SCALE/TSUNAMI tools to uncertainty quantification and sensitivity analysis of the reactor design.
This work is intended to strengthen safety margins, performance reliability, and licensing readiness, accelerating KRONOS MMR™ design maturation and commercialization efforts. The voucher funds work at the DOE laboratory rather than providing a direct cash grant to the company and is the company’s second GAIN voucher and the first tied specifically to KRONOS MMR™.
Nano Nuclear Energy Inc. describes a new step in its relationship with Argentina’s state-owned nuclear company Dioxitek S.A. The company has submitted a private proposal to Dioxitek for the potential joint development of a natural uranium hexafluoride (UF6) production facility using Dioxitek’s existing infrastructure in Argentina.
This proposal follows a non-binding Memorandum of Understanding signed in August 2025 to assess Argentina’s natural uranium conversion capacity. The project remains at an early, exploratory stage and is subject to review under Argentinian law, further technical and financial work with local stakeholders, and the potential negotiation and execution of definitive agreements. The company highlights substantial regulatory, technology, funding, and licensing risks that could prevent the project, or its broader nuclear plans, from progressing as anticipated.
NANO Nuclear Energy Inc. reported that a Construction Permit Application (CPA) has been formally submitted to the U.S. Nuclear Regulatory Commission for its KRONOS MMR™ microreactor, in partnership with The Grainger College of Engineering at the University of Illinois Urbana-Champaign.
The company states this makes it the first commercially-ready microreactor developer and the third commercially-ready Generation IV advanced reactor developer to reach the CPA stage, a key milestone that requires advanced engineering, safety analysis, and extensive regulatory engagement. NANO Nuclear views this step as moving KRONOS MMR™ from concept toward a licensable, build‑ready system on the university’s campus.
The press release notes that the CPA submission follows completion of a readiness assessment with the NRC and reflects years of technical refinement. The company estimates the NRC’s formal review of the CPA will take approximately 12 months, after which it aims to progress toward construction authorization, reactor operation, commercial licensing, and potential fleet‑scale deployment.
