Recent Japan HALEU transfer, Venezuela HEU removal support, and U.S. domestic HALEU delivery underscore STS’s mission-proven capabilities and progress towards NANO Nuclear’s broader vision of building a vertically integrated advanced nuclear platform.
NEW YORK, N.Y., May 28, 2026 (GLOBE NEWSWIRE) — NANO Nuclear Energy Inc. (NASDAQ: NNE) (“NANO Nuclear” or “the Company”), a leading advanced nuclear micro modular reactor and technology company focused on developing clean energy solutions, today announced recent U.S. Department of Energy (“DOE”) and National Nuclear Security Administration (“NNSA”) aligned nuclear materials transport campaigns supported by its recently acquired subsidiary, Secured Transportation Services LLC (“STS”). STS is a specialized U.S. based, globally operating nuclear logistics, transportation and services company specializing in the safe, secure and compliant movement of radioactive and nuclear materials.
The completed missions include a record-setting international shipment of high-assay low-enriched uranium (HALEU) from Japan, support for the removal of highly enriched uranium (HEU) from Venezuela, and a second U.S. domestic HALEU delivery supporting advanced reactor fuel testing. Together, these campaigns demonstrate STS’s position as a trusted and experienced nuclear logistics partner capable of supporting complex, highly regulated domestic and international missions for DOE, NNSA, and the broader advanced nuclear sector.
Historic Japan HALEU Transfer and Associated Spent Fuel Logistics
STS served as the DOE’s prime logistics contractor for a major international campaign involving the transfer of approximately 1.7 metric tons of HALEU from Japan — announced by the NNSA as the largest single international uranium shipment in its history — along with the transport of six Type B spent nuclear fuel casks to the DOE’s Savannah River Site in Aiken, South Carolina.
The campaign required coordinated international licensing, maritime transport, port operations, security planning, customs coordination, and final overland delivery to U.S. destination facilities. The HALEU is expected to support U.S. advanced reactor fuel needs through DOE’s HALEU Availability Program.
Venezuela HEU Removal Support
STS also provided logistics planning and U.S. domestic transfer support for NNSA’s accelerated removal of 13.5 kilograms of HEU from Venezuela’s dormant RV-1 research reactor. The mission supported U.S. nonproliferation objectives and helped eliminate a long-standing proliferation risk in the Western Hemisphere. The material was also transported to the Savannah River Site, where it is expected to be processed and down blended for future use in America’s advanced nuclear fuel supply chain.
Second Domestic HALEU Delivery
In addition to its international mission work, STS completed a separate U.S. domestic HALEU transport campaign supporting advanced reactor fuel testing programs. This delivery further demonstrates STS’s ability to execute multiple high-priority nuclear logistics missions safely, securely, and efficiently.

STS Acquisition Adds Proven Nuclear Transportation and Logistics Capabilities, Enhances NANO’s Strategic Focus on Vertical Integration and Supports Future Reactor Deployments
NANO Nuclear’s acquisition of STS adds proven nuclear transportation and logistics capabilities, including established experience in Type A and Type B radioactive materials transport, multi-modal campaign execution, regulatory compliance, international permitting, security coordination, and DOE and NNSA mission support.
With the addition of STS, NANO Nuclear believes it now has the in-house capabilities and infrastructure to support fuel-cycle logistics and future microreactor deployments both in the U.S. and around the world. As demand for HALEU, advanced reactor fuel qualification, spent fuel management and secure nuclear materials transport increases, NANO Nuclear expects STS’s mission-proven logistics capabilities to strengthen the Company’s broader platform across the nuclear fuel supply chain, fuel and spent fuel transportation, microreactor deployment planning and long-term nuclear services.

“STS’s execution of these recent DOE and NNSA-aligned missions demonstrates exactly why integrating STS into NANO Nuclear is so strategically significant. These campaigns showcase the advanced expertise, regulatory discipline, and operational capabilities that are now part of our microreactor and fuel supply chain platform,” said James Walker, Chief Executive Officer of NANO Nuclear Energy. “By bringing STS into the NANO Nuclear ecosystem, we have strengthened one of the most critical and capacity-constrained segments of the advanced nuclear supply chain: the safe, compliant movement of fuel and other nuclear materials. This capability not only supports our fuel-cycle strategy and microreactor deployment plans, but also positions us as one of the few companies developing the capability to deliver an integrated end-to-end advanced nuclear solution. The success of these missions reaffirms that STS is accelerating our ability to deploy next-generation nuclear systems globally.”
“STS has earned its reputation as a trusted and experienced partner for some of the nation’s most important nuclear transportation missions, and we’ve completed many incredibly difficult nuclear shipments with a strong record of success and compliance,” said Roy Boyd, Founder & President of STS. “Our organization is pleased to participate in these important initiatives that support the mission of the DOE and NNSA. These programs are vital to the safety of the United States and to the path forward for advanced nuclear energy. STS has performed movements throughout the world in all types of variable regulatory spaces and mission constraints. With NANO Nuclear’s support, we are well-positioned to expand that capability and help meet the logistics demands of the next generation of nuclear energy.”
“These latest STS-supported missions underscore the tremendous value of our acquisition and reinforce why the integration of a world-class nuclear logistics organization is a major step forward for NANO Nuclear. STS’s work on the largest ever single international uranium shipment in NNSA history, its support for the removal of HEU from Venezuela, and its domestic HALEU delivery highlight proven capabilities and expertise that very few organizations have globally,” said Jay Yu, Chairman and President of NANO Nuclear Energy. “With STS, we control a vital link in the nuclear value chain — one that is essential for scaling microreactor deployment, strengthening domestic fuel-cycle resilience, and enabling the advanced nuclear industry to grow. These accomplishments validate our strategy to build a fully vertically integrated nuclear energy company with the infrastructure, expertise, and execution ability needed to support national priorities and commercial customers alike. We are building the logistics backbone required for the next generation of nuclear energy, and these missions demonstrate the impact of that vision coming to life.”
