Drone Strike Damages Chernobyl Containment

A drone strike on February 14 damaged the protective shield over Ukraine's Chernobyl nuclear site, compromising its ability to contain radioactive material from the 1986 disaster, the United Nations' International Atomic Energy Agency announced Friday. The agency, known as the IAEA, confirmed through on-site inspections that the structure, called the New Safe Confinement, has lost key safety functions, including its confinement capability, though radiation levels outside the facility remain unchanged.

The attack targeted the massive arch-shaped steel enclosure built in 2019 over the ruins of Reactor No. 4, the unit destroyed in the world's worst nuclear accident. Ukrainian authorities attributed the strike to a Russian drone carrying a high-explosive warhead, which punctured the outer cladding and ignited a fire. Russian officials have denied involvement. IAEA inspectors found no irreversible harm to the shield's load-bearing elements or monitoring systems, but the damage has left the 36,000-ton structure vulnerable to environmental factors like wind, rain, and snow, potentially allowing radioactive dust to escape in the future.
