Progress Energy Inc. has restarted two nuclear reactors at its southeast North Carolina plant that were shut down for 10 days as a precaution.
Progress Energy spokesman Mike Hughes said the Brunswick Nuclear Plant began ramping up its electricity generation Thursday.
The reactors were forced to shut down after one of four emergency diesel generators stopped last month and wouldn't restart. Regulations require a shutdown if a problem with a diesel generator can't be fixed within seven days. The generators provide emergency power for plant operations.
The Nuclear Regulatory Commission will issue a report on the shutdown within two months.
The company also operates nuclear plants in South Carolina and Florida.
