The unharmed Unit 1 reactor at Three Mile Island did not resume operation until 1985. None found adverse health effects. Today, there are 96 reactors in use, supplying 20% of the nation's electricity. The Department of Energy supports more nuclear plants as a way to decrease U.S. reliance on foreign oil and to cut greenhouse gas emissions. The Three Mile Island power station was named after the island on which it was situated in the Susquehanna River near Harrisburg, Pa. The following explanation of the Three Mile Island accident and the changes to regulations that resulted from it has been compiled by NucNet for communicators and executives in the civil nuclear energy industry. At least a dozen studies assessed the release of radiation and possible effects. Judge Sylvia Rambo said there was no proof to substantiate the plaintiffs' claims of health damages from the accident. Three mile island (nuclear power plant) accident 1. For example: A 2009 article, “Startling Revelations About the Three Mile Island Nuclear Disaster,” reveals many contradictions to the government’s claim that the Three Mile Island tragedy did not pose any public threat..
