About

Civil nuclear resilience, watched continuously.

Nuclear Risk Watch continuously correlates public hazard data — earthquakes, wildfires, floods, storms and conflict — with publicly documented civil nuclear facilities, and shows which sites face elevated external hazard exposure right now, why, and what changed. Every exposure score comes with a plain-English rationale based on the hazard’s type, severity, proximity and recency.

Exposure is not impact. The score measures the strength, proximity and recency of publicly reported external hazards near a site. It does not measure the engineering safety of the facility, its vulnerability or the likely consequences, and it does not predict a nuclear incident.

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 external hazard exposure 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. Read the full methodology, weights and limitations.

Coverage

Nuclear Risk Watch currently monitors 294 publicly documented civil nuclear locations, derived principally from Wikidata and curated by hand. Coverage varies by facility type and country and should not be interpreted as a complete register of all nuclear or radiological sites. Research reactors, fuel-cycle plants and waste facilities are under-represented, and records for jurisdictions with limited public reporting may be incomplete or out of date.

Hazard & event data

  • USGS Earthquake Hazards Program — Earthquakes (public domain)
  • GDACS — Floods, cyclones, droughts, volcanic activity — UN OCHA & European Commission (JRC)
  • NASA FIRMS — Active-fire / wildfire detections (NASA EOSDIS)
  • Armed conflict — represented by curated, hand-reviewed entries. No automated conflict feed is in use.

Disclaimer

Exposure scores are explainable estimates of external hazard conditions for situational awareness — not official safety assessments. Figures shown across the site are live snapshots and will change as feeds update. Imagery resolution from open sources reflects environmental context, not structural detail.
