Total U.S. nuclear plant availability saw a small increase early Aug. 8 to 96.07%, up from 95.53% on Aug. 7 but still lower than the 96.81% reported on the same day last year.

Supporting total production was higher output at two reactors. Exelon Corp.'s Limerick 2 in Pennsylvania returned to full power early Aug. 8, rising from 70% on Aug. 7. Tennessee Valley Authority's Watts Bar 2 in Tennessee was pegged at 52% early Aug. 8, up from 40% the day prior.

In addition, the Nine Mile Point 2 plant in New York, which is owned by Exelon Corp, EDF Group and Long Island Power Authority, was warming up at 5% early Aug. 8. The unit was automatically scrammed on Aug. 5 following high reactor pressure, according to a report filed with the U.S. Nuclear Regulatory Commission.

As of early Aug. 8, Vistra Energy Corp.'s Comanche Peak 2 in Texas and Exelon's Quad Cities 2 in Illinois remain offline.
