Repurposing Retired Navy Reactors for AI Data Centers: A New Energy Frontier
12/27/2025, 1:42:30 AM
Proposal Overview
HGP Intelligent Energy, a Texas-based company, has proposed to the U.S. Department of Energy (DOE) the repurposing of two retired U.S. Navy nuclear reactors for an AI data center project at Oak Ridge National Laboratory in Tennessee. This initiative aims to harness the reactors to generate between 450 to 520 megawatts of power, sufficient to supply energy to approximately 360,000 homes. The reactors in question are the Westinghouse A4W reactors from Nimitz-class aircraft carriers and General Electric S8G reactors from Los Angeles-class submarines. If approved, this would mark the first instance of military reactors being adapted for civilian use.
Background and Context
The U.S. Navy has operated over 100 nuclear reactors for more than 50 years without any radiological accidents, showcasing their reliability. The proposal comes amid a growing demand for energy to support the expanding artificial intelligence sector, which requires continuous and substantial power. HGP's plan is seen as a cost-effective alternative to constructing new nuclear plants, with estimated costs ranging from $1 million to $4 million per megawatt, significantly lower than new builds.
Financial and Operational Considerations
HGP Intelligent Energy plans to seek a loan guarantee from the DOE, with the total project cost estimated between $1.8 billion and $2.1 billion. The company intends to establish a revenue-sharing program with the government and create a decommissioning fund to manage the costs associated with retired nuclear materials. The project aims to provide steady, carbon-free baseload electricity, addressing the increasing strain on traditional power grids.
Criticism and Opposition
Despite the potential benefits, the proposal has attracted skepticism from experts. Critics argue that naval reactors are primarily designed for propulsion rather than grid power and utilize highly enriched fuel, raising regulatory and security concerns. Additionally, the adaptation of military reactors for civilian use would necessitate extensive redesign and safety reviews, presenting significant challenges.
Official Statements & Responses
HGP's CEO, Gregory Forero, emphasized the company's capability to execute the project safely and at scale, stating, “We already know how to do this safely and at scale.” The proposal reflects a broader trend among technology companies and energy developers reconsidering nuclear power as a viable option for supplying reliable, low-emission electricity.
What's Next
As the demand for energy-intensive AI data centers grows, the conversation around nuclear power is intensifying, particularly in states like Michigan, which is facing its own energy challenges. The state has set a clean-energy standard of 100% by 2040, prompting utilities to explore various power sources, including the potential restart of the Palisades nuclear plant. The future of HGP's proposal and similar initiatives will likely depend on regulatory approvals, community acceptance, and the evolving landscape of energy needs in the digital economy.
Conflicting Reports & Gaps
While HGP's proposal is positioned as a solution to the energy demands of AI data centers, there remains uncertainty regarding the practicality and safety of repurposing military reactors. The complexities of federal oversight, security protocols, and community acceptance could significantly impact the project's feasibility and timeline.
