Total U.S. nuclear plant availability ticked higher early Aug. 10 to 96.67%, up from 96.45% on Aug. 9 but still much lower than the 98.15% reported on the same day a year ago.
Total output rose despite the loss of Dominion Energy Inc.'s Surry 1 reactor in Virginia. According to a report filed with the U.S. Nuclear Regulatory Commission, the unit was taken offline from 34% late Aug. 9, owing to a reactor coolant system leakage.
Offsetting the outage was increased production at two units. The Nine Mile Point 2 plant in New York, which is owned by Exelon Corp., EDF Group and Long Island Power Authority, was operating at 83% early Aug. 10, up from 65% the day prior. Tennessee Valley Authority's Watts Bar 2 in Tennessee was pegged at 91% early Aug. 10, up from 69% on Aug. 9.
