Securing the Fuel Supply Chain
The rapid development of advanced nuclear reactors is driving a surge in demand for High-Assay Low-Enriched Uranium (HALEU). To secure their fuel supply chains, reactor developers are increasingly signing long-term offtake agreements with enrichment companies, providing the financial certainty needed to expand domestic HALEU production capacity.
TerraPower and Quantum Leap Energy
Quantum Leap Energy (QLE) has secured crucial purchase agreements with TerraPower, a leading advanced reactor developer. Under the agreement, QLE plans to supply TerraPower with up to 150 tons of HALEU over a 10-year period from 2028 to 2037. This fuel will be produced at the planned Pelindaba facility in South Africa, a joint venture between QLE and Necsa. The agreement provides a clear demand signal for QLE's proprietary Aerodynamic Separation Process and Quantum Enrichment technologies.
Centrus Energy and Radiant Microreactors
In another significant market development, Centrus Energy and Radiant signed a multiyear agreement in September 2026 for HALEU fuel to be used in Radiant's Kaleidos microreactors. Deliveries are expected to begin before the end of the decade to support both commercial and national-security deployments. Importantly, the agreement includes prepayments from Radiant to help Centrus expand its domestic nuclear-fuel enrichment capacity in the United States.
These offtake agreements are critical for de-risking HALEU production projects, transforming the advanced reactor market from a theoretical concept into a commercially viable reality.
As more advanced reactor designs move toward commercialization, similar fuel supply agreements will be essential. The collaboration between reactor developers and enrichment firms is forging a resilient, domestic HALEU supply chain that will underpin the next generation of clean, reliable nuclear energy.
