US approves first data center-specific small nuclear reactor — the BWRX-300 may be covering not just the UK, but America too
US regulators have approved the Tennessee Valley Authority to construct the first BWRX-300 small modular reactor specifically designed for data center power needs. The Nuclear Regulatory Commission completed its assessment in 14 months, allowing construction to begin at the Clinch River site. While TVA may eventually build up to four units, the project still requires an additional license before it can load fuel and generate electricity.
- ▪The US Nuclear Regulatory Commission approved TVA's construction of the BWRX-300 reactor at the Clinch River site after a 14-month review process.
- ▪The 300MW boiling-water reactor is intended to address rising electricity demand from artificial intelligence infrastructure and data centers.
- ▪TVA is considering building as many as four BWRX-300 units at the location, though specific construction timelines have not yet been decided.
- ▪The utility must obtain a separate license before it is permitted to load nuclear fuel or begin commercial electricity generation.
- ▪The same reactor technology is also being proposed for deployment in the UK and Canada.
