Giant cooling towers at Constellation Energy's Three Mile Island nuclear plant in Pennsylvania have sat dormant for so long that grass has sprung up in the towers' hollowed-out bases and wildlife roam inside. "It's still eerie walking in here and it's, just, quiet," Constellation regulatory assurance manager Craig Smith said during a tour of the plant last week. Smith, who worked at Three Mile Island when Constellation shut the site’s remaining reactor in 2019, is now preparing for a restart.
