The Nuclear Regulatory Commission (NRC) has approved a request by Duke Energy (NYSE:DUK) to increase the generating capacity of Catawba Nuclear Station Unit 1 by 1.7%.
The NRC staff found that Duke Energy could safely increase the reactor’s output primarily through more accurate means of measuring feedwater flow. The staff determination was based on its review of Duke Energy’s evaluations showing the plant’s design can handle the increased power level, NRC said in a May 4 news release.
The power uprate for the Catawba plant, located in York County, South Carolina which is about 18 miles south of Charlotte, N.C., will increase Unit 1’s generating capacity from approximately 1,167 to 1,187 MW electric. Duke Energy intends to implement the uprate this month.
Catawba Unit 1 is a pressurized water reactor (PWR) that entered service in 1985, one year before Unit 2.
The NRC previously published a notice about the power uprate application on Nov. 4, 2014, providing the public an opportunity to comment or request a hearing.
