Bluecore Energy has raised an oversubscribed $50 million seed round, including $10 million in previously disclosed pre-seed funding, to develop compact nuclear reactors mounted on floating barges. Led by Silverton Partners, the financing follows the company's emergence from stealth in July and will fund engineering, regulatory approvals, nuclear fuel purchases and hiring. Bluecore's initial light-water reactor design targets roughly 10 megawatts of continuous output, using ocean water for cooling and subsea cables to supply ports, data centers, remote islands and coastal communities. The company has secured its first barge and is developing a non-fueled, electrically heated prototype at the Port of Long Beach. Formal engagement with the U.S. Nuclear Regulatory Commission and U.S. Coast Guard began in August 2026, but Bluecore has yet to build a fueled reactor or obtain operating approvals. It also faces California restrictions on new nuclear plants and supply-chain challenges before commercial deployment, which remains years away.
