Three Mile Island

views updated

Three Mile Island Island on the River Susquehanna near Harrisburg, Pennyslvania, USA. It is the site of a nuclear power-generating plant where a near-disastrous accident took place in March 1979. The accident involved the failure of the feedwater system, which picks up heat from the system that has circulated through the reactor core. The accident released radioactive water and gases into the environment.
