How can the global energy grid keep pace with fast-growing demand from new data centers supporting artificial intelligence (AI) and cloud computing? Nuclear energy and coastal waters offer a potential answer.

The potential for floating nuclear-powered data centers is explored in depth in the latest research from ABS and Herbert Engineering. Pathways to a Low Carbon Future Floating Nuclear Power Data Center details design considerations for a floating data center that would use large river estuaries or coastal waters as a heat sink for both servers and small modular reactors (SMR) onboard a purpose-built barge.

The study provides ABS and the industry with important insight into heat and energy management for both servers and reactors, weight distribution, structural considerations, and other design features for floating nuclear power data centers. This will assist the identification of design issues that will inform future Rules development.

The report builds upon previous ABS and Herbert Engineering research around marinized and offshore applications for nuclear energy, including Pathways to a Low Carbon Future Floating Nuclear Power Plant and Pathways to a Low Carbon Future LNG Carrier Nuclear Ship Concept Design.

ABS launched the industry’s first comprehensive rules for floating nuclear power plants, Requirements for Nuclear Power Systems for Marine and Offshore Applications, in 2024.
