Texas Energy Firm Proposes Reuse of Retired Naval Reactors to Power Data Centers

Maritime Cargo Chronicles (MCC) reports that a Texas-based energy company is advancing an unconventional proposal to repurpose decommissioned U.S. naval nuclear reactors as civilian power sources—targeting the rapidly growing energy demand of large-scale data centers.

According to information cited by Bloomberg, HGP Intelligent Energy LLC is exploring plans to deploy retired nuclear reactors from U.S. Navy submarines or aircraft carriers as compact powerplants capable of generating approximately 500 megawatts of electricity per installation. The company argues that such systems could provide reliable, long-duration power at a significantly lower cost than conventional nuclear facilities.

⚡ Cost, Speed, and Power Density Advantages

HGP estimates that a complete reactor-based power installation could be developed for approximately USD 2 billion, a fraction of the cost typically associated with building a new civilian nuclear power station. Traditional nuclear plants often require a decade or more to permit and construct, driven by regulatory complexity, public safety concerns, and labor constraints.

By contrast, HGP believes that a naval-reactor-based facility could be operational as early as 2029, benefiting from existing reactor designs, proven engineering standards, and a mature maintenance ecosystem. U.S. naval reactors are known for their high power-to-weight ratios, long endurance, and operational reliability, qualities that make them attractive for constant-load applications such as hyperscale computing facilities.

🧑‍🔧 Workforce and Supply Chain Readiness

One of the project’s key advantages, according to Maritime Cargo Chronicles, is workforce availability. The U.S. Navy’s nuclear propulsion program has trained thousands of highly specialized technicians—commonly referred to as “Navy nukes”—who are already familiar with reactor operations, safety protocols, and maintenance procedures.

In addition, the supply chain for reactor components, spare parts, and servicing infrastructure has been established over several decades, potentially reducing startup risks compared to first-of-a-kind civilian nuclear technologies.

🔐 Security and Proliferation Challenges

Despite the technical and economic appeal, the proposal faces substantial security and regulatory hurdles. U.S. naval reactors operate on highly enriched uranium (HEU), with uranium-235 concentrations of up to 93%, classified as weapons-grade material.

This raises serious nuclear non-proliferation and national security concerns, as both the fuel and reactor technologies are among the most tightly controlled assets of the U.S. defense establishment. Any civilian reuse would require extensive oversight from multiple federal agencies, including the Department of Energy and national security bodies.

🏗️ Proposed Site and Strategic Location

According to project documents reviewed by Bloomberg, the first proposed installation would be located in Oak Ridge, Tennessee—a city with deep historical ties to U.S. nuclear research and development. Oak Ridge is home to Oak Ridge National Laboratory (ORNL), a secure research hub that played a central role in the development of naval nuclear propulsion and continues to employ a large number of former Navy nuclear specialists.

The location could provide both technical expertise and institutional familiarity with advanced nuclear systems.

🔋 Developer Background and Grid Experience

HGP Intelligent Energy brings prior experience as a grid-scale energy infrastructure developer, having deployed more than 20 sites combining battery storage, thermal generation, and grid-resilience systems. The company was an early entrant into Texas’ battery-backup market and currently has nearly two dozen projects in development across the United States.

🌍 MCC Insight

From an energy-transition and infrastructure resilience perspective, Maritime Cargo Chronicles notes that the proposal reflects growing pressure to secure stable, carbon-free power sources for energy-intensive industries such as data centers, AI computing, and digital infrastructure.

While maritime-linked through naval propulsion heritage, the concept underscores how maritime nuclear technologies may increasingly influence land-based energy systems—provided regulatory, security, and political barriers can be addressed.
