Update (Sept. 12, 2017 4:15 p.m. EST):
Late Monday afternoon, Hurricane Irma had diminished to the point that the NRC exited monitoring mode and stopped staffing the Region II Incident Response Center in Atlanta. (The Operations Center at NRC headquarters in Maryland remains staffed 24/7 as usual.) Neither the Turkey Point nuclear plant nor the St. Lucie nuclear plant, both in Florida, lost offsite power during the storm, and both units at each plant are expected to be operating again this week. St. Lucie Unit 2 remained at full power throughout the storm, and Florida Power & Light tells the NRC it expects to restart St. Lucie Unit 1 today after local emergency management officials confirm they could implement their emergency plans for the plant. FPL has also indicated that it plans to restart both units at Turkey Point after emergency officials in South Florida provide the same assurances for the site. The NRC has returned to its normal inspection and oversight of Turkey Point, St. Lucie, and the other plants in the Southeast and will begin to evaluate lessons learned from Hurricane Irma in preparation for future storms that may affect nuclear plants.
Senior Public Affairs Officer, Region II
(Sept. 11, 2017): As Irma (now a tropical storm) continues to track through the southeast, the NRC continues to monitor its path and the nuclear power plants potentially along that route.
Turkey Point Unit 3, in south Florida, remains safely shut down, as it has been since Saturday. Operators at the Turkey Point plant shut down Unit 4 just before 7 p.m. Sunday evening due to a valve issue. The shutdown was uncomplicated, the plant is in a safe condition, and winds and rain have diminished at the site such that the plant staff exited their declaration of an unusual event at 4 a.m. Three NRC resident inspectors remain at the site, but the agency is now assessing steps to return to its normal inspection staffing within the next day or two.
At St. Lucie, also in Florida, operators are reducing power on Unit 1 due to salt buildup on insulators in the switchyard that supplies offsite power and plant employees are working to resolve this situation. St. Lucie Unit 2 remains at full power. Two NRC resident inspectors remain at the site, but it is expected that NRC will return to normal inspection staffing at this site, also within a day or two.
As of Monday morning, the Region II Incident Response Center staff is monitoring potential effects from the storm on the Hatch nuclear plant in south Georgia and the Farley nuclear plant in south Alabama. The two units at Hatch and the two units at Farley are currently at full power. Even though the staffs at both sites have completed storm preparations, it appears that projected winds will not be strong enough to affect plant operations at these two locations.
The NRC’s Region II continues to be in monitoring mode and the Incident Response Center in Atlanta is staffed. However, predicted wind and rain from the storm has prompted the closure of the Region II office as well as other federal agencies in the area.
