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.
On June 8, technicians reported an increase of chloride concentration in the reactor water, indicating a leak of Connecticut River water into the plant’s condenser.
On Tuesday, the plant’s power output was reduced to 26 percent.
Last year, a report commissioned by the state found that the plant was putting off needed fixes to its condensers until it gets a decision on whether it will be allowed to operate past 2012.
