Nano Nuclear signs 3-year engineering deal with IMPSA for reactor parts

October 21, 2026 8:00 AM EDT

Nano Nuclear Energy (NASDAQ: NNE) has signed a three-year Engineering Services Master Agreement with the U.S. subsidiary of IMPSA, an Argentine engineering and heavy-manufacturing company, to support engineering, design-for-manufacture and potential future fabrication of components for its KRONOS MMR™ Energy System, according to a press release.



The agreement establishes a framework for Nano Nuclear to draw on IMPSA's experience in nuclear pressure vessels, ASME Section III manufacturing, welding, non-destructive examination, quality assurance and heavy-component fabrication. The reactor pressure vessel is identified as a principal component under evaluation, with reactor cavity cooling systems, spent-fuel storage systems and transportation components cited as additional areas of potential collaboration.



As an initial step under the agreement, the two companies are beginning a KRONOS MMR™ Design Review and Assessment covering engineering consulting and manufacturability feasibility. The program is expected to run approximately six months and will include an independent review of KRONOS MMR™ components against ASME Boiler and Pressure Vessel Code Section III requirements.



The agreement describes IMPSA as one of the few companies in Latin America certified with ASME N and ASME III N stamps, giving it the ability to engineer and construct Class 1 heavy nuclear components.



"Advanced reactors have to move from drawings and calculations to modular components that can be manufactured repeatedly, inspected, qualified and assembled," said James Walker, Chief Executive Officer of Nano Nuclear Energy.



The agreement is non-exclusive. Any future component fabrication or commercial activities beyond the initial engineering scope will be subject to results of the engineering work, applicable regulatory requirements and additional agreements between the parties.
