Output at the Pilgrim nuclear power plant in Plymouth, Mass., had to be decreased by 15 percent last week, after a heat wave made the water in Cape Cod too hot to use to cool the reactor, the Associated Press reports. The reactor is operating at full power, according to The Boston Globe.
The U.S. Nuclear Regulatory Commission requires that cooling water must be below 75 degrees, but a recent heat wave in the region caused water temperatures to soar, according to the Boston Globe.
A unit at the Millstone nuclear plant in Connecticut was shut down in August 2012 after workers discovered cooling water was 1.7 degrees warmer than required.
