Three Mile Island, the site of the demolition of 1979, is completely shut down



HARRISBURG, Pa. – The money-losing Three Mile Island, the 1979 area of ​​America's worst commercial nuclear accident, was shut down Friday by its energy giant owner.

End of 45-year electricity generating career for Three Mile Island Unit 1 came after Chicago-based Exelon Corp. tried and failed to get financial support from Pennsylvania spring.

Three Mile Island's Unit 1 opened in 1974 and was licensed to operate through 2034, but Exelon complained that the plant was losing money in competitive electricity markets.

Three Mile Island also faced particularly difficult finances because the 1

979 accident that destroyed Unit 2 left it with only one reactor.

Disassembly of Unit 1, dismantling of buildings and removing spent fuel can take six decades and cost more more than $ 1 billion, Exelon estimates, even though companies are speeding up purchasing radioactive material enforcement to buy retired US nuclear reactors and promise to do so in less than ten years.

The broken unit 2 is sealed and its two cooling towers still stand. Core was sent many years ago to the U.S. Department of Energy & # 39; s Idaho National Laboratory. What remains in the containment building remains highly radioactive and encased in concrete.

Work on dismantling Unit 2 is scheduled to begin in 2041 and be completed by 2053, the owner, FirstEnergy, has said.

No nuclear power plants proposed after the 1979 accident have been successfully completed and put into operation in the United States.
