FILE - In this Aug. 6, 1979 file photo, protestors march past the Vermont Yankee nuclear power plant in Vernon, Vt. Vermont Yankee's initial 40-year license expires Wednesday, March 21, 2012.

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/Donna Light, File) less
