Offshore nuclear barges could power ports and data centers—starting with California, where nuclear is banned

The Port of Long Beach has entered a partnership to host offshore nuclear barges that could generate electricity for the harbor’s operations and adjacent data centers. The agreement, announced by Bluecore Energy, marks the first new nuclear‑related project in California in decades, despite the state’s long‑standing ban on nuclear power. Press Telegram described the concept as a 'pinch of salt'—a modest step toward diversifying Long Beach’s energy mix.

The initiative follows a landmark port deal highlighted by The Cool Down and Fortune, positioning floating reactors as a solution for high‑density energy demand at maritime facilities and tech clusters. Advocates argue that the barges can deliver reliable, low‑carbon power, while the partnership targets the growing load of container handling equipment and data‑center cooling needs. The proposal is pitched as a way to power both the port’s logistics equipment and the region’s expanding data‑center footprint, a point emphasized by Fortune.

Coverage from the Los Angeles Times raises questions about Long Beach’s readiness and the regulatory pathway in a jurisdiction that prohibits nuclear plants. Details on licensing, safety standards, and timelines remain sparse, leaving it unclear how the project will navigate the ban or secure approvals before construction can begin.
