Nuclear safety officials dinged Raleigh-based Progress Energy for a minor safety violation at its Brunswick nuclear plant near Wilmington.
The Nuclear Regulatory Commission said this morning that the plant's emergency diesel generators were not properly protected from possible flooding during a hurricane. The generators are needed as a backup source of electric power to operate pumps and other emergency equipment required to keep nuclear fuel from melting down and releasing radioactivity.
The generators were not properly protected because the Brunswick plant had not sealed off the fuel-oil tank room that stores the diesel to run the generators.
The agency said the oversight was of "low to moderate safety significance." It did not merit a fine, but the NRC will increase its oversight of the nuclear plant with an extra inspection.


Kelly L. Becker, a regional DOT traffic engineer, recommended today that DOT install three black-on-yellow arrow chevrons on the outside of the curve, replacing one there now. She recommended two new signs to remind northbound drivers that they are approaching the curve, and the relocation of an existing curve-ahead sign to provide more advance warning for southbound drivers.
