This Day In History: The Chernobyl Disaster

On April 26, 1986, the unthinkable happened when during a test of a poorly designed reactor coupled with woefully trained personnel led to an explosion in reactor no. 4, and resulted in a meltdown that destroyed the reactor building. WIKI: The disaster occurred during a test to simulate cooling the reactor during an accident in blackout conditions. The operators carried out the test despite an accidental drop in reactor power.
A design issue when attempting to shut down the reactor in those conditions resulted in a dramatic power surge. The reactor components ruptured and lost coolant, and the resulting steam explosions and meltdown destroyed the reactor building. This was followed by a reactor core fire that spread radioactive contaminants across the Soviet Union and Europe.read more
