TOKYO — Dozens of protesters shouted and danced at the gate of a nuclear power plant as it restarted Sunday, the first to go back online since Japan shut down all of its reactors for safety checks following the Fukushima nuclear disaster. Image: Ohi nuclear power plant
The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine (Ukrainian SSR), which was under the jurisdiction of Moscow. An explosion and fire released large quantities of radioactive contamination into the atmosphere, which spread over Western USSR and Europe. It is considered the worst nuclear power accident in history, and is one of only two classified as a level 7 event on the International Nuclear Event Scale.
