Federal regulators are launching a special inspection of a nuclear power plant outside North Carolina's capital city that was forced to shut down last week.
The Nuclear Regulatory Commission said in a news release Wednesday that two specialists will look into the issue, which was uncovered when plant operators at the Duke Energy-owned plant took a second look at year-old data. They want to know why the tiny sign of corrosion and cracking wasn't found earlier.
Duke Energy spokeswoman Rita Sipe says the country's largest electric company also is examining why the problem wasn't found sooner. The NRC release said repairs have begun.
Charlotte-based Duke Energy took over the plant after it acquired Raleigh-based Progress Energy last year.
