About This Dataset
Largest Nuclear Power Stations in the World 2026
The biggest nuclear power stations in operation in 2026, ranked by installed capacity in megawatts. A station here is a site, not a reactor: most of these run several reactors side by side, which is how they reach capacities no single unit could.
