BRUNSWICK COUNTY, NC (WECT) - The U.S. Nuclear Regulatory Commission says fuel oil tank rooms that serve the Brunswick Nuclear Plant's emergency diesel generators were not properly protected from possible flooding. According to a news release from the NRC, this is a finding of "low to moderate safety significance" and will lead to increased inspection of the facility.
On the safety significance scale, this is a "white" finding, which is one step up from the lowest safety level of green.
The NRC release says the violation involved the failure to identify and correct issues in the fuel oil tank rooms that made them more susceptible to flooding during a hurricane. The emergency diesel generators are used to power cooling systems for the reactors should the plant lose power off site.
An inspector from the NRC detailed the finding a report on November 29th. Company officials didn't contest the finding and didn't discuss the issue during a regulatory conference. They have installed new sealant material to close openings on the oil tank rooms and constructed barriers to limit possible wave run-up to the facility.
The NRC says this finding will lead to more oversight for the Brunswick plant, including a supplemental inspection.
