In this undated photo provided by Vermont Yankee, workers build the power plant's nuclear core in Vernon, Vt. Vermont Yankee's initial 40-year license expires Wednesday, March 21, 2012. It has won approval from the federal Nuclear Regulatory Commission to operate an additional 20 years. The state Public Service Board has yet to rule on the plant's future, but it's expected the Vernon reactor will continue operating in the meantime. (AP Photo/Vermont Yankee)
