ABC News Nightline - Chernobyl Disaster - April 29, 1986

Early report from Ted Koppel, Sam Donaldson and interviews with nuclear experts on what today is considered the most disastrous nuclear power plant accident in history, both in terms of cost and casualties. It occurred three days before this broadcast, on April 25-26, 1986, in the northern Ukraine which was then part of the USSR. The rest of the world was, at the time of this broadcast, making a best guess on the extent of the accident and casualties due to the cryptic reports coming out of the Soviet Union. Past nuclear accidents, and coverups, are also explored in this broadcast.
