Generated 2026-11-12 20:23 UTC

As of 2026-11-12 20:23 UTC, 1 of 294 monitored civil nuclear facilities are at ELEVATED external exposure or higher. The most significant is Zaporizhzhia Nuclear Power Plant (HIGH, 62.8/100), driven by Conflict 0 km away (17 h ago). The most common active hazard near monitored sites is Earthquake (17 of 18 events in range of a site in the last 7 days).

How external hazard exposure 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.

This measures hazard exposure only. It does not incorporate facility vulnerability, likely consequences or engineering safety, and does not predict a nuclear incident. Full method and limitations: nuclearwatch.evodefence.uk/methodology
