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.

Analysis

Kori in South Korea is the largest at 7,489 MW, 1.03 times the 7,268 MW of Hanul. The 8 stations here total 51,828 MW. 4 of them are in China, and 3 countries are represented in total. The smallest on the chart, Hanbit, is rated at 5,875 MW, 78% of the leader.
