Bluecore Energy purchases low-enriched uranium to advance first floating nuclear energy system development

Bluecore Energy announced on Oct. 13 the purchase of low-enriched uranium, marking a significant step for its first nuclear energy system. The purchase brings the team closer to fuel fabrication and testing for its compact floating reactor. The California-based company obtained uranium hexafluoride (UF₆) with a 4.95% uranium-235 concentration through nuclear fuel intermediary WMC. The material is currently stored at a U.S. nuclear fuel facility outside California, and Bluecore is advancing fuel fabrication, testing, and validation plans.

Advancing the fuel supply phase

This purchase moves development work from reactor design and non-fuel hardware to the phase of establishing a physical fuel supply. However, Bluecore has not reported operating a fueled reactor, and the announcement did not provide a timeline for the first fuel test.

The purchased uranium exists in UF₆ form, a material used in the enrichment stage of the nuclear fuel cycle. Before it can be used in conventional reactor fuel assemblies, the material will undergo further processing. Bluecore will ultimately convert the UF₆ into uranium dioxide (UO₂), which can be fabricated into fuel pellets and assembled into nuclear fuel. Acquiring enriched uranium is a key link in the fuel supply path, but it is only the first stage of developing an operational nuclear energy system. Fuel fabrication, quality certification, testing, and regulatory requirements remain challenges ahead. WMC operates at the front end of the nuclear fuel cycle and provides customers with uranium procurement, conversion and enrichment products, logistics, storage, financing, and processing support.

Regulatory and technical development progress

Bluecore is advancing its regulatory and technical development in parallel. In August, the company began pre-application engagement with the U.S. Nuclear Regulatory Commission (NRC), presenting a conceptual overview of its design and discussing its proposed regulatory strategy with agency staff. The U.S. Coast Guard also participated in the meeting. Its participation comes as the NRC and Coast Guard establish a framework for coordinating civilian maritime nuclear projects. These discussions are part of the company's efforts to meet the requirements of nuclear technology and its intended maritime deployment. Pre-application engagement does not constitute a construction or operating license.

Floating nuclear power plant design approval

The company also received an approval in principle (AIP) from the American Bureau of Shipping (ABS) for its floating nuclear power plant design. The approval was granted in June 2026 and is the first ABS AIP for a U.S.-designed floating nuclear power plant. The assessment evaluated the concept against applicable ABS rules and guidelines and established a roadmap of technical requirements to be addressed as the design matures. An AIP is an early design assessment, not a final construction or operating license.

Bluecore is headquartered at the Port of Long Beach, California, where the company is developing its first maritime nuclear energy system and a non-fueled prototype reactor module. The company says its technology was designed from the outset for floating maritime platforms, not adapted from traditional land-based nuclear power plants. Depending on the application, potential uses could include ports, coastal infrastructure, and artificial intelligence data centers. Bluecore emphasizes that the company does not operate an active nuclear reactor or store nuclear fuel at its Long Beach headquarters. Its purchased enriched uranium is stored at another U.S. nuclear fuel facility.

The company recently also raised $50 million in seed funding, an announcement made less than three months after emerging from stealth mode. The company says this funding and the latest technical milestones are supporting parallel work in engineering, safety, testing, and regulatory engagement. Next steps include advancing fuel fabrication and quality certification while continuing to develop its reactor system and meet federal and maritime requirements.

Significance of Bluecore Energy's nuclear energy system development

Bluecore Energy's purchase of low-enriched uranium marks significant progress in its floating nuclear energy system development. With the establishment of fuel supply, the company faces nuclear technology challenges including quality certification and regulatory requirements. Engagement with the U.S. Nuclear Regulatory Commission and obtaining the classification society's design approval demonstrate its efforts in regulatory compliance and technical development. These steps not only help advance the realization of its nuclear energy system but may also have far-reaching implications for future maritime nuclear technology applications.
