Quick answer — Nuclear power plants worldwide now

Of the 202 sites on this list, 17 had at least one event reported or measured nearby in the last 30 days and 185 had nothing in Delta’s sources. 42 distinct events in all. Titles summarise the reporting; they are not facts this page has checked.

Why this list

The International Atomic Energy Agency counted 413 operational nuclear power reactors across 31 Member States at the end of 2025, with a net capacity of 377.1 GW(e), and 72 reactors with 76.9 GW(e) under construction.

This list is by site, not by reactor: one plant usually holds several reactors, and each site is listed once. It takes every site that OpenStreetMap maps as a nuclear power plant, except those mapped as shut down.

Sites mapped in OpenStreetMap as nuclear power plants, including a few research and military reactors mapped the same way. Sites mapped as shut down, such as Chornobyl and Fukushima Daiichi, are not listed, and plants that are not mapped are missing.

Plants with events in the last 30 days

Within 2 km of each plant, newest first, up to five per plant. Measured events show only that something was measured and when; their detail is part of the full account of each event.

Nothing in Delta’s sources (185)

No report or measurement linked to these plants reached Delta in the last 30 days. This is not a statement about their operations.

Frequently Asked Questions

How are events matched to a plant on this list?▼
Each plant is a point with a 2 km radius. An event is listed when its reporting names a registered facility inside that radius, when it was placed precisely enough to fall inside it, or when it is a measurement linked to a facility there. Events placed only at the level of a city or country are not listed unless they name a facility.
Does “nothing in Delta’s sources” mean the plant is operating normally?▼
No. It means no report or measurement linked to that plant reached Delta in the window. It is not a statement about the plant’s operations or safety.
Are the event titles verified?▼
No. Each title summarises what the reporting said. Each event page lists the articles behind it.
Can I watch this list myself?▼
Yes. “Copy this list to my Watchlist” opens the Watchlist with these plants filled in; you check the list before anything is created, and you get one summary email a day for the list. How many sites you can watch depends on your plan. The Watchlist adds up to 100 sites at a time, so this list is copied in 3 parts that go into the same list.
