It’s hard to believe, but no major hurricane has made landfall in the continental United States since 2005. Hurricane Wilma came ashore in southwest Florida in October of that year as a Category 3 storm, but then skirted the peninsula and went back into the Atlantic.
During this record respite of 11 years, the NRC never stopped training and preparing for big storms, including major hurricanes. Storm preparations were an important part of the post-Fukushima enhancements that have made U.S. commercial nuclear plants safer.
This week, a mammoth storm known as Hurricane Matthew is stalking Florida’s East Coast, having already taken its toll on Haiti, the Dominican Republic, Cuba and the Bahamas. The NRC and the companies that operate nuclear facilities began preparations for Matthew long before its anticipated path was clear.
Late Tuesday, the staff at Florida Power and Light’s St. Lucie plant in Port St. Lucie, not far from the predicted landfall, declared an unusual event, the lowest of NRC’s emergency classifications, because of the hurricane warning. The plant staff began severe weather procedures, which include making sure any equipment or debris that could be affected by wind or water has been removed or secured. Staff also conducted walk downs of important plant systems and ensured emergency supplies were adequate.
Similar work was being done at Turkey Point, south of Miami, another FPL plant, and at Brunswick, a Duke Energy station near Southport, N.C.
The NRC’s resident inspectors at each plant, meanwhile, worked to verify the storm preparations were completed as expected, paying special attention to the condition of emergency diesel generators that would be used if the plants lose offsite power.
The NRC maintains 24-hour staffing at any plant expected to experience hurricane-force winds. Since the resident inspectors live near the plant and need to take care of their families and homes, other agency personnel are dispatched to storm sites to help with staffing. One resident inspector from Tennessee volunteered to drive to southeastern North Carolina to staff Brunswick. Some other inspectors at or near the plants on other inspection duties volunteered to stay and provide staffing.
The NRC’s Region II Incident Response Center in Atlanta will be staffed around the clock during the storm, monitoring its path while keeping in contact with plant operators, NRC on-site inspectors, state emergency officials in the affected states and NRC headquarters.
Previous hurricanes have shown that nuclear plants are robust facilities that can withstand extremely high winds and storm surges. As Matthew approaches, the NRC is working to ensure plant operators have taken actions to protect the plants, safely shut down if necessary and ensure power is available to keep the plants in a safe condition until the storm has passed.
