Three Mile Island Generating Station is located in Central Pennsylvania, about 12 miles south of Harrisburg, in Londonderry Township. The station is built on an Island in the Susquehanna River. Three Mile Island Unit 1 began commercial operations on September 2, 1974. The initial construction cost for the plant was about $400 million. First Energy Company, Akron, Ohio, owns Three Mile Island Unit 2, the plant damaged during an accident in 1979.

Three Mile Island is a pressurized water reactor designed by Babcock and Wilcox. The plant is capable of generating 850 net megawatts; enough power to support the electricity needs of over three hundred thousand average American homes.

On March 28, 1979, and for several days thereafter — as a result of technical malfunctions and human error — Three Mile Island's Unit 2 Nuclear Generating Station was the scene of the nation’s worst commercial nuclear accident. Radiation was released, a part of the nuclear core was damaged, and thousands of residents evacuated the area. Events here would cause basic changes throughout the world’s nuclear power industry.

Comments

  • I am very much a supporter of nuclear power. Do not mislead, however. Approximately 1/3 of the core did, indeed meltdown. During the accident the top portion of the fuel cells became uncovered with coolant and about the upper 1/3 melted into the bottom of the reactor vessel. The reactor vessel did successfully contain the fuel, which solidified into a mass at the bottom.
