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.
