US approves first data center-specific small nuclear reactor

The US Nuclear Regulatory Commission has granted the Tennessee Valley Authority (TVA) authorization to construct the BWRX-300, a 300MW small modular reactor, at its Clinch River site. This approval marks a significant step in addressing the surging electricity demands of AI infrastructure and data centers. The BWRX-300 utilizes advanced boiling-water technology designed for enhanced safety and simplified construction compared to traditional large-scale nuclear plants. While this permit allows construction to begin, TVA must still secure additional licenses before fuel loading or commercial operation. The project is being closely watched as a test for standardized reactor deployment, with similar initiatives currently proposed in the UK, Canada, and Texas. By leveraging a repeatable design, developers hope to improve efficiency and reduce the costs that have historically plagued large nuclear projects, providing a stable, weather-independent power source for the growing digital economy.
