Copenhagen Atomics And Urenco To Collaborate On UF6 Deconversion Facility

Nucnet • November 4, 2026

Copenhagen Atomics, a developer of thorium-fuelled molten salt reactor (MSR) technology, and London-headquartered uranium enrichment company Urenco are collaborating to build a uranium hexafluoride (UF6) deconversion facility in Copenhagen.

Denmark-based Copenhagen Atomics said it has also bought low-enriched uranium (LEU) from Urenco for its first reactors.

It said the existing global supply chain is only able to deliver LEU as UF6, but molten salt reactors require uranium tetrafluoride (UF4).

Copenhagen Atomics and Urenco Collaborate on Uranium Deconversion Facility Copenhagen Atomics and Urenco have signed an agreement to develop a uranium deconversion facility in Copenhagen. This facility will convert uranium hexafluoride (UF6) into uranium tetrafluoride (UF4), which is necessary for molten salt reactor (MSR) fuel production. Copenhagen Atomics will source enriched UF6 and handle the deconversion process to manufacture high-purity fuel salts for its reactors and other MSR developers. The facility aims to establish a commercial fuel supply chain for MSRs, addressing supply-chain needs as the industry progresses from research to commercial demonstration. Details on the facility's construction schedule and processing capacity have not been disclosed. The collaboration marks a significant step in the advanced nuclear technology sector. 2 sources 21
