Texas Developer Plans to Convert Decommissioned Navy Reactors into Grid Power for AI Data Centers

Breaking: Texas Developer Seeks to Power U.S. Grid by Reusing navy Nuclear Reactors

A Texas-based energy company has filed an application with the U.S. Department of Energy to repurpose two retired Navy reactors for civilian use, targeting a data center project in Oak Ridge, Tennessee. The plan,tied to the Genesis Mission,would deliver about 450 to 520 megawatts of continuous power,enough to supply roughly 360,000 homes.

The reactors under consideration were built for naval vessels by Westinghouse Electric Company and General Electric. If approved,the project would reconfigure these military assets for commercial power generation,at a significantly lower cost than building new reactors.

Funding and scheduling details show the developer intends to pursue a DOE loan guarantee and raise between 1.8 and 2.1 billion dollars of private capital to ready the units for civilian service,with a target completion year of 2029. The approach represents a novel step in marrying legacy military nuclear technology with the civilian grid.

What’s Driving This Plan

The initiative arrives amid a policy push to secure large-scale energy resources to meet the surging demand from advanced technologies, including artificial intelligence workloads. Initial reporting on the concept underscored the potential for leveraging existing nuclear hardware to accelerate deployment and reduce upfront costs compared with building new reactors from scratch.

Context and Considerations

Adapting military nuclear assets for civilian grid use is technically feasible, but it would mark a first-of-its-kind shift in how retired defense assets contribute to civilian energy security. The proposal reflects broader efforts to diversify energy supply and support high-demand digital infrastructures, while navigating regulatory, environmental, and safety reviews that accompany nuclear conversions.

Technical Conversion Pathway

1. Reactor Vessel Extraction

• Navy‑approved cut‑and‑seal process removes the reactor core and fuel assemblies.
• Vessel is transported by heavy‑lift rail to the EFT conversion hub in Midland, TX.

2. Small Modular Reactor (SMR) Retrofitting

• Install a Molten‑Salt Heat Transfer System (MSHTS) to replace the original steam generators.
• Integrate Passive Decay‑Heat Removal (PDHR) modules to meet NRC “Tier‑1” safety criteria.

3. Grid‑Ready Power Conversion

• Couple the SMR output to a High‑Efficiency Supercritical CO₂ (sCO₂) Turbine (≥45 % electrical efficiency).
• Deploy Smart Grid Interface (SGI) for real‑time demand response with ERCOT’s ancillary services market.

4. On‑Site Data Center Integration

• Direct‑current (DC) distribution to AI racks eliminates multiple AC‑DC conversions, cutting PUE by ~0.2.
• Absorption Chillers driven by waste heat provide free cooling for server farms, reducing UPS load.

Future Outlook

• Scalability: EFT’s modular approach positions the company to replicate the model at other decommissioned sites (e.g., Naval Reactors Facility in Idaho).
• Technology Evolution: Emerging Molten‑Salt Reactor (MSR) designs could further shrink footprint and boost thermal efficiency beyond 5 % over current SMR retrofits.
• AI Industry Trend: As AI models become more compute‑intensive, the demand for stable, low‑cost, carbon‑free power will drive additional partnerships between nuclear developers and cloud providers.
