A Duke Energy (NYSE:DUK) spokesperson said late June 25 that the Catawba 1 nuclear unit in South Carolina is not back in service yet after being taken offline for a planned refueling and maintenance outage May 6.
The unit has, however, been listed by the Nuclear Regulatory Commission (NRC) as producing a small amount of electric generation during the past couple of days.
Catawba 1 was listed at 16% generation in the NRC daily reactor status report on June 25. It was listed at 15% on June 26.
Catawba Units 1 and 2 are both pressurized water reactors (PWRs) commissioned in the 1980s. Together the two Catawba units have an operating capacity of more than 2,200 MW.
