RALEIGH, N.C. (AP) -- 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.
A Nuclear Regulatory Commission spokesman said Wednesday that two specialists will study what led up to the shutdown after a problem was uncovered using year-old data. They want to know why a flaw inside the nuclear reactor wasn't found until Duke Energy employees took a new look at test results from last year.
Operators at the plant in southern Wake County found a tiny sign of corrosion and cracking that needs repair, which has begun.
Duke Energy representatives did not immediately respond to a message seeking comment Wednesday.
Charlotte-based Duke Energy took over the Harris plant after its merger with Raleigh-based Progress Energy last year.
