Nuclear update: Total output slips with 2 curtailments

Total U.S. nuclear plant availability fell to 86.86% early March 22, down from 87.51% on March 21 but higher than the 81.62% reported on the same day a year ago.

Production curtailments at two reactors pulled down total output. Exelon Corp.'s LaSalle 1 in Illinois saw production fall from 100% on March 21 to 24% early March 22. In addition, Exelon's Nine Mile Point 1 in New York was pegged at 85% power early March 22, dropping from 100% on March 21.

The return of two reactors offset the curtailments. Tennessee Valley Authority's Browns Ferry 1 in Alabama was operating at 24% early March 22 after being taken offline March 19 for undisclosed reasons. PG&E Corp.'s Diablo Canyon 2 in California was warming up at 7% early March 22 after being shut Feb. 11 for a refueling outage.

As of early March 22, 10 units remain offline.
