Bluecore Raises US$50M to Float Small Nuclear Reactors Into Ports
Bluecore Energy, a nuclear startup headquartered inside the Port of Long Beach, California, said on September 8, 2026 that it had raised an oversubscribed US$50 million seed round roughly two months after emerging from stealth. Silverton Partners led the round. Returning investors included Slauson & Co., Harlem Capital, Precursor Ventures and Ripple co-founder Chris Larsen, and new backers included Collab Capital, MaC Ventures and HartBeat Ventures, the fund founded by comedian Kevin Hart, along with angel investors from Tesla, Uber, Amazon and Google. The round closed in about eight weeks and brings total funding to roughly US$60 million, following a US$10 million pre-seed announced in July. The company was founded earlier this year by Chief Executive Officer Kofi Asante, a former Uber executive, and is described as the first US nuclear company founded by a Black entrepreneur.
Bluecore is building small modular, water-cooled reactors mounted on floating barges, a design meant to be towed to a customer rather than built on a site. The first system is engineered for about 10 megawatts of continuous electrical output, enough for roughly 15,000 homes, with refueling required only once every few years. Target customers are ports, coastal industry, AI data centers, islands and remote communities without reliable grid access, with reactors potentially anchored offshore and connected by subsea cable. The capital funds engineering, hardware, testing, licensing and hiring. A non-fueled prototype is under construction at Long Beach to validate monitoring and control systems, and the company began formal regulatory engagement in August with the Nuclear Regulatory Commission and the US Coast Guard, which recently signed a memorandum of understanding to coordinate oversight of civilian floating nuclear plants. The team includes engineers from SpaceX, Blue Origin, Northrop Grumman, Rivian and Toyota, former Navy nuclear submarine officers, and licensing lead Megan Moyette, also a former Navy nuclear officer.
Market Context
The demand story behind the round is electricity for computing. Deloitte estimates US data center power demand could rise roughly fivefold by 2035 to about 176 gigawatts, and calculates that newly built nuclear capacity could cover only around 10% of that growth even if 35 to 62 gigawatts came online. Nuclear plants generated more than 19% of US electricity in 2024 from less than 8% of installed capacity, with capacity factors above 92.5% against 56% for natural gas and 35% for wind. That reliability is what makes reactors attractive to buyers who need power around the clock, and what has pushed a wave of venture money into small modular designs.
Bluecore's differentiator is siting rather than physics. Its reactors use light-water technology, the same basic approach that has run US commercial plants for decades, and the barge is what is new: no land acquisition, no interconnection queue, and a unit that can in principle be built in a shipyard and relocated. The precedent is thin. Russia's Akademik Lomonosov, at up to 70 megawatts, remains the only operating floating nuclear plant in the world, several times larger than Bluecore's first system. The US comparison is military, with naval reactors at sea since 1955, which is the analogy Asante leans on. The company also faces the cost history of the sector: nuclear construction overruns above 100% are common, and no US small modular reactor developer has yet delivered a commercial unit.
The Number
"The Navy is doing this as we speak, for the last 70 years, and has never had an accident. We just made it smaller, so you can actually move things around in days." — Kofi Asante, Founder and Chief Executive Officer, Bluecore Energy
Regional Relevance
For the United States, the round tests whether the country's nuclear buildout can move from construction projects to manufactured products. Every gigawatt of new demand from artificial intelligence runs into the same three bottlenecks: land, transmission interconnection and permitting timelines measured in years. A reactor on a barge is an attempt to route around all three by making the power plant mobile and shifting the work into a shipyard, where cost curves fall with repetition rather than rising with each bespoke site. The regulatory piece matters as much as the engineering, because the NRC has signaled that maritime reactors can be licensed under existing federal rules and has agreed to coordinate with the Coast Guard. If that pathway proves workable, it becomes a template other developers use.
For California and the Port of Long Beach, the tension is immediate. Bluecore is the first small modular reactor company headquartered inside a major US port, and the ports of Long Beach and Los Angeles are among the largest single sources of local emissions in Southern California, under sustained pressure to electrify cranes, trucks and ships. Nuclear power tied to a dock addresses that directly. But California maintains longstanding restrictions on new nuclear plants, which is why a company assembling reactors in Long Beach may end up selling its first units somewhere else entirely, including Alaska, island markets and Gulf Coast industrial sites.
There is also a capital-formation angle. The syndicate is unusual for a heavy industrial startup, mixing a traditional venture firm with funds built around underrepresented founders and celebrity capital. That Bluecore raised US$50 million in eight weeks, with no fueled reactor and no license, says as much about the current appetite for anything adjacent to AI power demand as it does about the technology.
The Other Side
How far is this from actually producing electricity? Bluecore has a barge, a prototype without fuel, and preliminary conversations with two regulators. It does not have a licensed design, fuel, or a completed reactor. Even developers with far more capital and a decade of head start have not yet delivered a commercial small modular unit in the United States. A realistic first-power date is years out, and the seed round funds engineering and licensing work rather than deployment.
Does a 10-megawatt unit move the needle for data centers? A single hyperscale AI campus can draw hundreds of megawatts. At 10 megawatts, one Bluecore barge is closer to a port electrification project or an island utility than to a data center power contract, and serving the AI market would require either a much larger design or many units operating in parallel, each with its own licensing and staffing burden. The economics of small reactors have historically worsened, not improved, at small scale.
What about the politics of a reactor at a working port? Floating nuclear concentrates several sensitive questions in one place: marine accident risk, security at a facility handling international cargo, spent fuel handling on the water, and public consent in dense coastal communities. California's nuclear restrictions are only the formal version of that problem. Naval safety records are a strong argument, but the Navy operates under military control and outside civilian licensing, which is precisely the gap the NRC and Coast Guard now have to fill.
