U.K., north of Liverpool, Windscale Pile No.1: Fire in a graphite-cooled reactor
spewed radiation ower a 200 sq mi area in the countryside. 1976
East Germany, near Greifswald, Lubmin nuclear power plant: During a fire the
safety systems failed, causing the radioactive core of the reactor nearly to
melt down. 1979 March 28th.

lost its coolant, which caused the radioactive fuel to overheat and produced a
partial meltdown. Radioactive material was released. 1986 April 26th.
