Civil nuclear facilities are exposed to earthquakes, wildfire, flooding, storms, drought and armed conflict. The data describing those threats is public and constantly updated, but scattered across agencies and feeds. Nuclear Risk Watch continuously correlates that data into one inspectable picture.
What It Tracks
Nuclear Risk Watch monitors the world's known civil nuclear facilities against live natural-hazard and conflict data. It shows which sites are at elevated risk right now, with a plain reason attached to every result. It is live at nuclearwatch.evodefence.uk, free to view, and needs no login.
The platform carries hundreds of known nuclear facilities across dozens of countries. Behind the map, public hazard feeds are ingested and correlated against facility locations by geospatial proximity, then recalculated on a regular cycle so the picture changes over time rather than freezing at one snapshot.
Facilities
Publicly documented civil nuclear facilities with location and metadata.
Hazards
Earthquakes, wildfire, flooding, storms, drought, volcanic activity and conflict context.
Reasons
Every elevated result carries an interpretable reason, source trail and score band.
How The Score Works
Every score is the product of four interpretable factors: hazard type, severity, proximity and recency. That means a facility is not simply marked as risky; the platform can explain why the score has changed and what kind of pressure is driving it.
The score is an explainable estimate for situational awareness. It is not an official safety assessment, and it does not try to be. The value is in turning fragmented public data into a clear, current and inspectable answer to a simple question: which sites are under pressure right now, and why?
Where The Data Comes From
Real-time earthquakes come from the USGS Earthquake Hazards Program. Floods, tropical cyclones, droughts and volcanic activity come from GDACS. Active-fire and thermal detections come from NASA FIRMS. Facility metadata comes from Wikidata, and the map uses OpenStreetMap-derived basemap data.
Conflict context is treated cautiously. Authoritative sources such as ACLED and UCDP are access-gated, while broader open feeds can be too noisy for credible per-site scoring. The platform is designed to integrate stronger feeds as access allows, rather than dressing up weak signals as firm intelligence.
What It Is Not
Nuclear Risk Watch is civil and defensive in scope. It tracks resilience and hazard exposure for facilities that are already publicly documented. It does not deal in military targeting, classified information or hidden sites, and it is not affiliated with any operator, regulator or government.
How It Is Built
The front end is built with Next.js and TypeScript, with mapping handled by MapLibre GL. PostgreSQL and PostGIS perform the geospatial correlation, while background workers refresh and rescore the data. The emphasis is on visible reasoning, public sources and independent infrastructure.
