A nuclear explosion – not high pressure steam – started the chain reaction of events that destroyed the reactor
Saturday 26 April 1986 was a day that shook the world. At 1.23 am, the number 4 reactor at the Chernobyl nuclear power plant near Pripyat, Ukraine, leapt to more than 100 times its usual operating power. As a result, high pressure steam in the reactor vessel exploded and parts of the reactor shot through the roof of the building, igniting fires that ejected highly radioactive nuclides over much of the western Soviet Union and Europe.
