US-based Nano Nuclear Energy Inc. has announced the signing of a memorandum of understanding with Dioxitek S.A., a state-owned Argentine company and the country’s only producer of uranium dioxide for nuclear fuel fabrication. The agreement aims to evaluate current uranium-to-hexafluoride (UF₆) conversion capabilities and associated infrastructure with a view to potential industrial collaboration.
While non-binding, the agreement establishes a formal framework for cooperation between the two companies. The review will focus on the technical assessment of Argentina’s local supply chain for transforming yellowcake into UF₆, the feedstock required for nuclear fuel enrichment. Subject to feasibility findings, a production line could be developed at Dioxitek’s existing facility.
A partnership supported by bilateral nuclear frameworks
The initiative falls under the peaceful nuclear cooperation agreement between Argentina and the United States, known as the “123 Agreement”, established under the U.S. Atomic Energy Act of 1954. This legal framework enables US companies to enter into strategic civil nuclear partnerships with foreign entities.
With strategic uranium reserves, Argentina holds potential to expand its domestic conversion and enrichment capacities, amid increasing pressure on the global UF₆ supply chain. The development of a local production line would reduce import dependency and reinforce national autonomy across the entire nuclear fuel cycle.
Expanded Nano Nuclear presence in South America
The announcement aligns with Nano Nuclear’s broader strategy to establish a footprint in Argentina, as the country moves to revise its regulatory framework in key segments of the nuclear sector. The agreement with Dioxitek could pave the way for long-term industrial investment aligned with Argentina’s stated goals of modernising its nuclear infrastructure.
“This collaboration with Dioxitek marks a key step for Nano Nuclear in South America,” said Jay Yu, Founder and Chairman of the company. “It provides access to real-world operational data with the potential to positively impact the global nuclear fuel supply chain.”
