PALO, Iowa (AP) — A repair to a flaw in a weld on the reactor at
the Duane Arnold Energy Center near Palo has been
Spokeswoman for the eastern Iowa nuclear power plant, Renee Nelson,
says the work was done along with other activities during this
month's planned shutdown for maintenance. She says repairing the
weld won't extend the planned outage, but she would not disclose
when the plant will be back online.
The Gazette in Cedar Rapids reports that the plant's owner, NextEra
Energy, found the flaw during recent inspections. The company says
the flaw penetrated 70 percent through a pipe wall. It is being
blamed on "stress corrosion."
NextEra says the kind of fault found in the reactor is not unique
to Duane Arnold.
