About Three Mile Island

The Three Mile Island Generating Station is part of the Exelon Nuclear Fleet located on Three Mile Island in the Susquehanna River near Harrisburg, Pennsylvania.

The name is not derived from the size of the island, but from the fact that TMI is three miles downriver from Middletown Pennsylvania.
