How did they clean up Three Mile Island?

The cleanup at the Three Mile Island nuclear plant has ended after 14 years with a final puff of radioactive steam from the evaporator used to get rid of contaminated water from the 1979 accident. The steam, released at various times by the electric evaporator, carried tritium, a radioactive form of hydrogen.
