Basically, there was a coolant malfunction that caused the nuclear power plant to automatically shut down at 4am on March 28, 1979. At that point a release valve malfunctioned and did not close allowing the coolant to drain away and causing the decay heat in the core to not be removed correctly. To compound this problem, the user interface in the control room had very ambiguous warnings and the operators could not identify the problems with much speed. There was some radioactive gas released, but several research teams have determined cancer incidence has not increased in the surrounding area.
