Ukraine currently operates four nuclear power plants with a total of 15 reactors. One of them, the Zaporizhzhia Nuclear Power Station, is the largest plant in Europe and has been under Russian occupation since March 2022. Russia, for its part, has 37 reactors divided among 11 power plants.If all or even some of these reactors were attacked and destroyed simultaneously, the destructive impact would be beyond calculation. The Chernobyl nuclear accident that occurred in Ukraine in 1986, and which remains the worst disaster involving nuclear energy in history, killed dozens and led to long-term health problems for thousands of others. It also led to the evacuation of tens of thousands of people and rendered the surrounding area permanently uninhabitable, spreading radioactivity over a large area and even into Western Europe.
