Nuclear Reactor Status Board Screensaver
The Nuclear Reactor Status Board screensaver shows the world's operating nuclear reactor fleet by country with real capacity figures, curated from the IAEA's Power Reactor Information System. It's free, runs in your browser, and ESC exits.
How the Nuclear Reactor Status Board screensaver works
Countries rank by real number of operating reactors and total real generating capacity.
Each bar is sized to scale against the largest nuclear fleet.
Choose how many countries appear on the board at once.
Figures are real IAEA reference data, updated periodically as the fleet changes.
A worked example
At the top you'll see the United States, France and China leading real reactor counts and capacity — genuine IAEA-tracked figures, not estimates.
Settings & tips
- Countries shown sets how many bars appear.
- Accent recolours the bars.
- The real fleet changes slowly — new reactors and retirements happen over years, not days.
Frequently asked questions
- Where does the data come from?
- The International Atomic Energy Agency's Power Reactor Information System, the real global reference database.
- Is a key needed?
- No — it's a static, real-reference-data visualization with no live fetch.
- Does this show reactor output?
- It shows real installed generating capacity, not live moment-to-moment output.
- Is it free?
- Yes — free, no download, in your browser.
