About
Civil nuclear resilience, watched continuously.
Nuclear Risk Watch continuously correlates public hazard data — earthquakes, wildfires, floods, storms and conflict — against the world’s known nuclear facilities, and shows which sites are at elevated risk right now, why, and what changed. Every risk score comes with a plain-English rationale based on the hazard’s type, severity, proximity and recency.
It is built entirely on open, public data sources and is independent — not affiliated with any operator, regulator or government. Its scope is civil resilience and environmental hazard exposure, not military targeting, classified information or facility surveillance.

How risk is scored
Each score (0–100, banded LOW → SEVERE) is the product of four interpretable factors, so there is always a clear reason behind it:
- Hazard type — how threatening that class of hazard is to a nuclear site.
- Severity — normalised intensity (e.g. earthquake magnitude, fire radiative power).
- Proximity — influence falls away with distance from the site.
- Recency — influence decays over time, with longer persistence for sustained threats such as conflict.
The picture refreshes hourly, around the clock.
