Total U.S. nuclear plant availability was eyed at 86.81% early March 19, slipping from 89.45% on March 16 but coming in above the 81.94%-rating reported on the same day in 2017.
Pulling down total production was the loss of several units for what private sources indicate is planned seasonal work. The units are: Duke Energy Corp.'s Catawba 2 in South Carolina, Entergy Corp.'s Indian Point 2 in New York and Exelon Corp.'s Quad Cities 2 in Illinois.
Additionally, Tennessee Valley Authority's Browns Ferry 1 in Alabama and Exelon's Nine Mile Point 1 in New York were both offline early March 19, down from 100% on March 16.
Meanwhile, several generating units returned to full power as of March 19, including Nebraska Public Power District's Cooper reactor in Nebraska, which was taken offline about a week earlier after a high pressure coolant injection system was declared inoperable.
Exelon's Calvert Cliffs 1 in Maryland, its LaSalle 1 in Illinois and Southern Co.'s Hatch 1 in Georgia all ramped up to 100% as of early March 19. The three reactors are exiting planned seasonal outages that began in February.
