NANO Nuclear advances KRONOS MMR NRC review
NANO Nuclear Energy Inc. is advancing the regulatory licensing of its KRONOS MMR Energy System after the U.S. Nuclear Regulatory Commission initiated formal review activities for the Construction Permit Application at the University of Illinois Urbana-Champaign. The NRC's review schedule targets an environmental assessment in Spring 2027 and a safety evaluation in early Fall 2027, with potential construction activities starting in the second half of 2027. Concurrently, the company is expanding global strategic engagements through summits in Africa, India, and Latin America.

NANO Nuclear Energy Inc. is advancing the regulatory licensing of its KRONOS MMRâ„¢ Energy System following the initiation of formal review activities by the U.S. Nuclear Regulatory Commission (NRC). On June 23, 2026, the NRC publicly announced that it had met with representatives from the University of Illinois Urbana-Champaign (U. of I.) and NANO Nuclear to mark the start of its review of the Construction Permit Application (CPA) and the planned KRONOS MMRâ„¢ research reactor project on the U. of I. campus. This meeting follows the agency's formal acceptance of the CPA on May 18, 2026, which triggered the environmental, safety, and technical review process for the planned deployment at the U. of I. campus, representing a major advancement toward regulatory licensing, construction, and future deployment of the reactor system.
The NRC's anticipated review schedule indicates the environmental assessment is expected in Spring 2027 and the safety evaluation in early Fall 2027. NANO Nuclear stated these milestones align with its expectations that the formal review could be completed in 2027, allowing initial construction activities to commence in the second half of 2027, subject to regulatory approvals and other customary project requirements. The company believes the commencement of formal NRC review activities reinforces the KRONOS MMRâ„¢ system's position as the first commercially-ready microreactor developer and highlights its broader strategy of accelerating commercialization through regulatory engagement, engineering advancement, and strategic partnerships.
Global Strategic Engagements
Concurrently, NANO Nuclear is expanding its global strategic engagements across emerging nuclear markets. The company participated in the Nuclear Energy Innovation Summit for Africa (NEISA) from May 19 to May 21, 2026, in Kigali, Rwanda, where Sarah Lennon, International Nuclear Policy Advisor, served as a panelist. In India, a delegation including NANO Nuclear met with government and private sector officials in New Delhi and Mumbai from May 17 to May 21, 2026. Additionally, the company attended the Latin America and Caribbean Regional Small Modular Reactor Workshop in Buenos Aires, Argentina, from June 2 to June 4, 2026, under the U.S. Department of State's FIRST Program.

Management and Technical Leadership
James Walker, Chief Executive Officer, noted that the commencement of formal NRC review activities demonstrates forward momentum for the KRONOS MMRâ„¢ program. Milos Atz, Director of Safety Analysis, emphasized that the review allows for detailed evaluation of environmental, safety, and technical information. Prof. Massimiliano Fratoni, Senior Director and Head of Reactor Design, continues to support the advancement of the prototype KRONOS MMRâ„¢ reactor at U. of I. and plans for its commercial deployment. The KRONOS MMRâ„¢ is a proprietary, stationary, high-temperature gas-cooled microreactor designed for clean energy applications.
