The Three Mile Island nuclear power plant unit that partially melted down in 1979 and shut down since was acquired Oct. 15 by Utah-based cleanup firm EnergySolutions in what it says will be its most technically challenging decommissioning project to date.
The contract at the Middletown, Pa., site needs a sign-off by the U.S. Nuclear Regulatory Commission and state regulators and is not set to be final until next year.
