The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

As flooding recedes around Brunswick nuclear power station, NRC considers when it can restart

Beyond Nuclear 20th Sept 2018 , The two-unit coastal Brunswick nuclear power station in South Port, NC was
powered down to zero power shortly in advance of the September 14th arrival
Hurricane Florence with Category 1 winds (sustained < 75 mph), storm surge
and torrential rainfall. Operators maintained the Brunswick units in “hot
standby” (reactor cooling water at 212O F and capable of steam powering
onsite turbines for emergency electricity) to provide an added measure of
power supply for reactor safety and cooling systems in the event of loss of
offsite power and backup emergency diesel generators.

However, throughout the storm, Duke Energy reported that the nuclear power station was in
“stable” condition and never lost offsite electricity power from the
grid providing primary power to safety systems and cooling.

A low-level emergency was declared September 15th when the reactor site was completely
surrounded by rising flood waters making it inaccessible by road. Two
shifts of workers were already housed onsite and supplied in advance for
the storm’s duration. Offsite access by road to the Brunswick units was
restored on September 18th and the “Unusual event” emergency was
terminated.

The continued flooding has damaged many of the bridges and
roads within the ten-mile radius that encompasses the radiological
evacuation planning zone for the Brunswick nuclear power station. As the
flooding recedes, the Federal Emergency Management Agency (FEMA) will
assess the damage to the infrastructure and will provide its recommendation
to the U.S. Nuclear Regulatory Commission (NRC) before Brunswick is allowed
to restart.
