Nuclear Risk Watch

Executive Briefing

Generated 2026-07-27 07:12 UTC

As of 2026-07-27 07:12 UTC, 1 of 294 monitored civil nuclear facilities are at ELEVATED risk or higher. The most significant is Blayais Nuclear Power Plant (SEVERE, 81.7/100), driven by Wildfire 59 km away (31 h ago). The most common active hazard near monitored sites is Wildfire (60 of 83 events within 500 km in the last 7 days).

How risk is evaluated

Each facility is scored 0–100 from four interpretable factors, multiplied together — so every score has a clear, stated reason:

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.
