What happened when a Russian drone struck the Chernobyl nuclear power plant's radiation shelter, and what are the safety implications?

President Zelensky reported that a Russian drone strike significantly damaged the radiation shelter (sarcophagus) covering the Chernobyl nuclear power plant, causing a fire that was subsequently extinguished. Despite the damage to this critical safety structure, radiation levels remain normal and are under constant monitoring. This incident is particularly concerning given Chernobyl's history as the site of the world's worst civil nuclear disaster in 1986, when a reactor explosion killed approximately 30 people immediately and exposed thousands to dangerous radiation levels. The sarcophagus was specifically designed to contain the lingering radiation from that catastrophic event. The attack highlights the dangerous intersection of military conflict and nuclear safety infrastructure, raising international concerns about the potential radiological consequences of targeting such sensitive facilities during warfare.
