Key Nuclear Energy Statistics (2026)
Key Findings: Nuclear Energy Statistics — 2026 Data
The headline figure for 2026 is 415 — nuclear reactors in operation globally (2024). This figure comes from IAEA PRIS 2024 and represents one of the most-cited benchmarks in this space.
Trends and Growth
Looking at broader trends, nuclear electricity generation globally (2023) stands at 2,602 TWh, according to IEA 2024. The data points to continued momentum in this area, driven by digital transformation, shifting consumer behaviour, and policy changes.
Regional Breakdown
While global-level statistics provide a useful overview, significant variation exists between regions and countries. Europe, North America, and Asia-Pacific each show distinct patterns in nuclear energy statistics, shaped by regulatory environments, infrastructure investment, and demographic factors. The statistics above reflect these regional nuances where data permits.
