Since February 2022, at least 127 incidents that threatened nuclear and radiation safety have been recorded as a result of Russian aggression, according to the analytical center DiXi Group.
“DiXi Group experts have collected all documented incidents at Ukraine’s nuclear facilities caused by Russia’s military actions since the beginning of the full-scale invasion. During this period, Russia has caused at least 127 events, confirmed by reports from the IAEA, official sources of the Ukrainian government, and the OECD Nuclear Energy Agency, which posed a threat to nuclear and radiation safety,” the statement said.
In particular, the following incidents were recorded:
- 23 cases of loss of external power supply to nuclear power plants;
- 25 direct strikes and shelling incidents — by drones, artillery, and missiles — targeting nuclear plant industrial sites or their immediate vicinity;
- 29 temporary reductions in nuclear power plant output due to instability in the energy system caused by attacks;
- 2 cases of damage to radiation monitoring systems and the New Safe Confinement at the Chornobyl site.
At the same time, 54 incidents (42.5% of the total) occurred at the Zaporizhzhia Nuclear Power Plant. The intensity of attacks on nuclear facilities increased in 2024, when 47 incidents were recorded near or directly at Ukraine’s nuclear plant sites. In January–April 2026, 16 incidents were recorded.
The term “incidents/events” refers to loss of nuclear power plants’ connection to transmission lines, strikes and shelling, temporary reductions in output due to attacks on the power system, damage to radiation monitoring systems, and other disruptions. Some of these incidents may be classified under the International Nuclear and Radiological Event Scale (INES). Categories may overlap: a single incident can involve multiple types of threats (for example, a strike that simultaneously causes loss of a power line and a forced reduction in plant output).
