Time was supposed to run out for the Vermont Yankee nuclear power plant Wednesday. Opponents eagerly looked forward to the shutdown when the plant's license expired, but that didn't happen.

Entergy Nuclear officials say power has been reduced at Vermont Yankee while technicians try to find and repair a leak of river water into the plant's cooling system.

Legislative leaders want to know what Vermont Yankee will charge utilities for electricity before they vote on whether to extend its operating license another 20 years.
