Bluecore Energy has purchased low-enriched uranium for its first nuclear energy system, as per an October 13 announcement. The purchase moves the team closer to fuel fabrication and testing for its compact floating reactor.

The California-based company secured uranium hexafluoride (UF₆) enriched to 4.95 percent uranium-235 through nuclear fuel intermediary WMC. The material is being held at a US nuclear fuel facility outside California while Bluecore advances plans for fuel fabrication, testing, and validation.

The purchase moves the development effort beyond reactor design and non-fueled hardware toward establishing a physical fuel supply. However, Bluecore has not yet reported operating a fueled reactor, and the announcement does not establish a timeline for its first fueled tests.

The purchased uranium is in the form of UF₆, which is used during the enrichment stage of the nuclear fuel cycle. Before it can be used in a conventional reactor fuel assembly, the material will undergo further processing.

Bluecore will eventually convert the UF₆ into uranium dioxide (UO₂), which it can manufacture into fuel pellets and assemble into nuclear fuel.

Securing enriched uranium establishes an important part of the fuel supply pathway, but it is only one stage in developing an operational nuclear energy system. Fuel fabrication, qualification, testing, and regulatory requirements remain ahead.

WMC operates across the front end of the nuclear fuel cycle and supports customers with uranium procurement, conversion and enrichment products, logistics, storage, financing, and processing.

Bluecore is pursuing its regulatory and technical development in parallel. In August, the company began pre-application engagement with the US Nuclear Regulatory Commission (NRC), presenting a conceptual overview of its design and discussing its proposed regulatory strategy with agency staff.
