Port of Long Beach signs deal to build small offshore nuclear reactors
The Port of Long Beach has leased space to startup Bluecore Energy to develop small modular reactors on barges, potentially marking California's first new nuclear project in 50 years. The project faces an unclear path around the state's 1976 nuclear moratorium.
For the first time in 50 years, California could see a new nuclear power project at one of the country's largest trade hubs. The Port of Long Beach is exploring small modular reactors, known as SMRs, that could eventually supply electricity for port operations and the ships that pass through. The proposal is being led by Bluecore Energy, a startup launched less than a year ago, which says its reactors are designed to float on barges.
"We're a few years away from the biggest energy crisis in a generation," said Kofi Asante, founder and CEO of Bluecore. "My team and I took nuclear reactor technology that's been running power plants safely for 70 years, made it smaller and put it on a barge."
The company said one SMR could power 15,000 homes. Its initial system is rated at 10 MWe, a capacity that can scale by pairing multiple units together, according to the startup. The reactors are designed to run for years on a single fueling cycle, making them suitable for continuous port operations.
The port has already leased space at Berth 48 to Bluecore, where the company is building and testing its reactor. In a separate arrangement, the port signed a cooperation agreement with the US Maritime Administration last month to help establish safety standards for maritime nuclear power use.
Regulatory and Technical Hurdles
Despite the momentum, the project faces a significant legal obstacle: California has banned new nuclear reactor construction since 1976, a moratorium tied to unresolved questions about high-level radioactive waste disposal. It remains unclear whether that prohibition applies to Bluecore's floating reactor design, and federal regulators are still being engaged.
Bluecore has not yet filed a formal application with the Nuclear Regulatory Commission (NRC) for deployment approval. The company was scheduled to meet with the NRC this week to present its reactor design and regulatory plans. An NRC report reportedly raised questions about how maritime nuclear deployments would address hazards such as sinking, capsizing, and severe weather extremes.
The Port of Long Beach, the Maritime Administration, and federal agencies including the Coast Guard and the Department of Energy are jointly developing operational and safety protocols. The Maritime Administration also began seeking industry input earlier this year on scalable, US-built small modular reactors for the marine transportation sector.
USC engineering professor Dr. Najm Meshkati, who sits on the state's independent safety panel for Diablo Canyon, noted that the physics behind small reactors isn't new, but placing one on a barge in a busy working port is novel and "should come with tougher, independent oversight." He stressed that the public must remain involved, urging: "If there is a public meeting, please go there. Please question. Please keep the feet of the regulators and the industry people to the fire."
Future potential
Port officials say nuclear power could eventually supply around-the-clock electricity as cargo operations become increasingly electrified across Long Beach's terminals. The technology could also extend to ships, data centers, and other coastal facilities located near water access points.
For now, the Long Beach initiative remains in the development and regulatory-planning stage, with no construction timeline confirmed. Whether the state's decades-old nuclear moratorium ultimately blocks or accommodates this barge-based approach remains an open, unresolved question — one that regulators, port officials, and Bluecore itself have yet to answer.

Port of Long Beach signs deal to build small offshore nuclear reactors
For the first time in 50 years, California could see a new nuclear power project at one of the country's largest trade hubs.
It involves small modular reactors, known as SMRs, which would generate electricity for the Port of Long Beach and the ships that pass through.
Startup company Bluecore Energy, launched less than a year ago, will develop the new technology.
The SMRs are designed to float on barges.
The port signed a cooperation agreement with the Federal Maritime Administration last month to help establish safety standards for the technology.
Separately, the port has already leased a space at Berth 48 to Bluecore, where the company is building and testing its reactor.
Bluecore said one SMR could power 15,000 homes.
The project could face some hurdles, mainly the 1976 ban California placed on new nuclear construction.
It's unclear if SMRs are included in that prohibition.
USC engineering professor Dr. Najm Meshkati commented on the project.
Meshkati also sits on the state's independent safety panel for Diablo Canyon, but made it clear he was speaking only for himself, not the committee.
He said the physics behind small reactors isn't new, but placing one on a barge in a busy working port is a novel idea that should come with tougher, independent oversight.
Meshkati said, 'We need to look at all these sources of energy equally and simultaneously but make sure that each one of them is implemented with the safest possible consideration.'
Bluecore said it's moving fast.
The company hasn't filed an application with the Nuclear Regulatory Commission yet but the two sides are reportedly meeting on Monday.
For now, the project remains in the early stages.
As it progresses, it could reshape how and where California gets its power.
Meshkati said the public has to stay involved with the process.
Meshkati urged, 'If there is a public meeting, please go there. Please question. Please keep the feet of the regulators and the industry people to the fire.'
Framing: Emphasizes the novelty of a first nuclear reactor on a boat in California, with a specific capacity figure (15,000 homes). Leaves out the regulatory hurdles and the fact that it's still in early development. — Measured, with a forward-looking but cautious tone. Example: 'For now, the Long Beach initiative remains firmly in the development and regulatory-planning stage, with no construction timeline confirmed.'

The Port of Long Beach is exploring small modular reactors that could eventually supply electricity for port operations and ships.
Bluecore Energy, a startup building compact nuclear reactors meant to operate from floating barges, is leading the proposal.
This marks a potential return of nuclear power development in California after nearly five decades under state restrictions.
The company's initial system is rated at 10 MWe, a capacity the startup says can scale through pairing multiple units together, an approach which suits continuous port operations partly because individual reactors are designed to run for years on a single fueling cycle.
The port has also signed a cooperation agreement with the US Maritime Administration to help establish safety standards for maritime nuclear power use.
The proposed system is water-cooled and would generate heat through nuclear fission, similar to conventional nuclear plants on land.
Port officials say nuclear power could eventually supply around-the-clock electricity as cargo operations become increasingly electrified across Long Beach's terminals.
The technology could also extend to ships, data centers, and other coastal facilities located near water access points.
California has maintained a moratorium on new nuclear fission reactor construction since 1976, tied to unresolved questions about high-level radioactive waste disposal.
It remains unclear how this long-standing state restriction would apply to Bluecore's proposed floating reactor design.
At the federal level, Bluecore has not yet filed a formal application with the Nuclear Regulatory Commission (NRC) for deployment approval.
The company was scheduled to meet with the NRC this week to present its reactor design and regulatory plans.
An NRC report reportedly raised questions about how maritime nuclear deployments would address hazards such as sinking, capsizing, and severe weather extremes.
The Port of Long Beach, the Maritime Administration, and federal agencies including the Coast Guard and Department of Energy are jointly developing operational and safety protocols.
The Maritime Administration also began seeking industry input earlier this year on scalable, US-built small modular reactors for the marine transportation sector.
For now, the Long Beach initiative remains firmly in the development and regulatory-planning stage, with no construction timeline confirmed.
If the project eventually advances past these early hurdles, Long Beach could become an early American test case for maritime small modular reactors serving port infrastructure.
Whether the state's decades-old nuclear moratorium ultimately blocks or accommodates this barge-based approach remains an open and unresolved question — one that regulators, port officials, and Bluecore itself have yet to answer.
Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
