Nuclear update: Total output tops 85% as 3 units return

Total U.S. nuclear plant availability topped the 85% level early May 10 at 85.06%, up from 83.52% on May 9 and also much higher than the 77.92% reported on the same day in 2017.

Providing a boost to total output was the return of three units across the country.

Susquehanna 1 in Pennsylvania, which is owned by Riverstone Holdings LLC and Allegheny Electric Cooperative Inc., saw production rise from 80% on May 9 to 93% early May 10.
