How old are most nuclear power plants?
The average age of these nuclear reactors is about 39 years old. The oldest operating reactor, Nine Mile Point Unit 1 in New York, began commercial operation in December 1969.
Where does nuclear waste go?
Low-level radioactive waste is collected and transported safely to one of four disposal facilities in South Carolina, Washington, Utah or Texas. Some low-level waste can be stored at the plant until its stops being radioactive and is safe to be disposed of like normal trash.
