Proposed Use of Retired Naval Reactors for Data Center Power Faces Challenges
DEFENSEDATA AND AI INFRASTRUCTURE
HGP proposes rewiring retired naval reactors for data centers at a cost of $1 million to $4 million per megawatt, requiring a decade to complete through five stages. The plan includes a revenue share with the government and a decommissioning fund.
However, the reactors use weapons-grade uranium, which civilian entities cannot possess, and licensing pathways are lacking. Additionally, military-designed systems would need complete reconstruction to meet civilian safety standards, negating cost benefits. Despite these challenges, the maritime cooling concept could reduce energy consumption compared to land-based data centers.
