Part of the roof has collapsed at Ukraine’s Chernobyl nuclear plant, where an explosion and reactor meltdown occurred in 1986, but authorities claim the site remains sealed and that there have been no changes in the radiation levels.
Some 80 construction workers were present at the site at the time of the incident, but no injuries were reported.
A massive concrete sarcophagus, which was built to contain leaking radiation from the exploded nuclear reactor, was not damaged by the roof collapse. International Business Times
