NANO Nuclear Signs Cooperation Memorandum with Hyundai for 45-Megawatt KRONOS Research Reactor

Key Facts

NANO Nuclear announced on October 27, 2026, that it had signed a memorandum of understanding with Hyundai Engineering to establish a framework for potential cooperation on the KRONOS micro modular reactor project at the University of Illinois Urbana-Champaign. The announcement includes discussion of broader cooperation in manufacturing and future deployment, but does not award the South Korean company a construction contract. Hyundai Engineering’s chief executive said the memorandum "establishes a basis for cooperation with a promising developer in advanced nuclear energy." He added that the company aims to gain experience by participating in pilot project and first-of-a-kind unit opportunities. The agreement comes as the university’s application for a construction permit for the reactor remains under review by the U.S. Nuclear Regulatory Commission.

Initial areas of focus include project execution planning, conventional and site work, procurement readiness, constructability and modularization studies, logistics, and supply chain development and localization plans in the United States. The memorandum sets out expected workstreams including constructability and modularization studies, construction sequencing and site mobilization, and preparation of civil and site work packages. It also covers identifying and prequalifying suppliers and planning for long-lead materials, as well as mapping suppliers in the United States and South Korea. The announced step therefore focuses on project preparation and reviewing execution requirements, rather than starting construction. Hyundai’s role could later expand to engineering, procurement and construction, construction management, equipment or component manufacturing, or support for KRONOS fleet deployment, if technical and commercial assessments find that appropriate.

But the memorandum is non-exclusive, does not itself award a specific work package, and does not require either party to finance or build the project. NANO said any paid scope would require a separate definitive agreement, while any expansion of Hyundai’s role remains subject to technical and commercial assessment, the availability of work scope, and university and regulatory requirements. The move from planning to contracted work therefore depends on subsequent agreements. Hyundai’s chief executive said the company wants to build experience in pilot and first-of-a-kind projects, describing the company’s objective in potential participation. The current memorandum sets an exploratory framework and initial workstreams; it does not establish that the company has secured revenue or a reactor construction contract.

The memorandum is tied to a project the U.S. Nuclear Regulatory Commission describes as a high-temperature gas-cooled research reactor with a thermal capacity of 45 megawatts. The project aims to provide heat to the university campus and support its carbon-neutrality goals, according to coverage by The Korea Times. The university says the proposed facility is intended for research and development, not as a commercial project, and that selling energy is not part of its current plan. The project’s goals also include training the workforce needed for next-generation reactor technologies and using the facility as a platform for technology testing. That places the companies’ cooperation in the context of a university research project, not an announced commercial power-generation plant.

According to the regulatory record, the University of Illinois filed its construction permit application on March 31, 2026, and the commission issued a letter accepting the filing on May 18, 2026. That means the application was accepted for filing, not that the commission approved construction; the case remains under review. According to the university, the licensing process requires a construction permit application first, followed by a separate application for an operating license. If a construction permit is issued, the university will still need operating approval before starting up the reactor. The commission’s published schedule targets issuance of a draft safety evaluation in February 2027 and a final evaluation in September 2027; these are review targets, not licensing decisions.

The partnership draws on Hyundai’s earlier technical ties in the micro modular reactor sector: its cooperation with USNC and the Korea Atomic Energy Research Institute on high-temperature gas-cooled reactor and micro modular reactor technologies began in 2012. NANO Nuclear later acquired USNC’s micro modular reactor technology in 2025. This timeline explains the background to the links between the companies and technologies, without meaning that Hyundai designed the KRONOS reactor itself. For NANO, the announcement connects technology acquired by the company with the university project, which is currently going through the regulatory process. The next step tied to the project remains dependent on progress in the commission’s review and on separate agreements that could define any execution or paid scope.

In trading, NANO Nuclear shares closed at $11.86 on October 26, 2026. They had closed at $12.96 on October 20, then $13.33 on October 21, $12.53 on October 22 and $12.16 on October 23. The October 26 close was below the closing levels recorded in the four previous sessions. The price was recorded before the company’s October 27 announcement, so it does not reflect any subsequent reaction to the news. The available data here do not include a closing price for the day of the announcement.
