Total U.S. nuclear plant availability increased to 89.72% early June 2, up from 89.16% on June 1 but still holding below the 93.94% level reported on the same day a year ago.
Giving a push to total production was the return of two reactors. SCANA Corp.'s V.C. Summer plant in South Carolina was at 30% early June 2. The unit was taken offline on April 8 for a refueling outage. Entergy Corp.'s Waterford 3 unit in Louisiana was at 18% early June 2. The reactor was shut on April 15 for planned seasonal work.
In addition, Public Service Enterprise Group Inc.'s Salem 2 plant in New Jersey was pegged at 98% early June 2, rising from 47% on June 1.
On the other hand, two units were curtailed. Exelon Corp.'s Braidwood 1 in Illinois saw output fall from 100% on June 1 to 76% early June 2. Vistra Energy Corp.'s Comanche Peak 2 plant in Texas was operating at 73% early June 2, down from 100% power the day prior.
