NRC Continues to Respond to Irma

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.

(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.

Update: The NRC Readies for Hurricane Irma

UPDATE (9/10/2017 – 10 a.m. EST): The NRC activated the Region II Incident Response Center in Atlanta and entered the agency’s monitoring mode just after 6 p.m.yesterday. One unit at the Turkey Point plant is shutdown, but the other unit continues to operate because winds on site have been projected to not exceed hurricane strength. Florida Power & Light has told the NRC it currently has no plans to shut down the two units at the St. Lucie plant because projected wind speeds there are also expected to be below the hurricane level.

Latest Press Release: NRC Preparing for Hurricane Irma Sept. 8, 2017

Roger Hannah
Senior Public Affairs Officer, Region II

At least two nuclear power plants, Turkey Point and St. Lucie, are in the predicted path of Hurricane Irma. Both are preparing for the strong and potentially damaging storm – just as they have for past dangerous hurricanes.

Twenty-five years ago, Turkey Point was directly in the path of Hurricane Andrew, a Category 5 storm, and although many of the plant’s structures were damaged and offsite power lines were lost, important safety equipment was safely maintained.

Florida Power & Light, the company that operates Turkey Point and St. Lucie, is working through a very detailed storm preparation procedure. That work includes checking equipment and supplies such as diesel generator fuel, securing or moving other equipment or items that might be blown around, and implementing a staffing plan to ensure enough operators and support staff are on site around the clock if roads become inaccessible.

Meanwhile, the NRC’s resident inspectors at the two sites are watching and ensuring company employees are following their procedures. The NRC’s Region II office in Atlanta has already dispatched two additional inspectors to Turkey Point and two others to St. Lucie so the resident inspectors assigned to those sites can take care of their homes and families.

As Hurricane Irma moves closer, the NRC will activate its Incident Response Center in Atlanta for around the clock staffing and begin ongoing communications with the plants and the NRC inspectors on site.

Procedures require both plants to be shut down prior to the onset of hurricane-force winds on site, and remain shut down until equipment has been checked and reliable offsite power lines are restored. The plants have diesel generators that can provide power to keep the plants in a safe condition for many days if offsite power is not available.

In addition, regional inspectors have been in contact with NRC license holders in Puerto Rico, Florida and other potentially affected states, which have responsibility for securing radioactive materials during the storm.

Hurricane Andrew and other natural events that have affected nuclear plants in past decades have provided the NRC with a wealth of experience in responding to conditions that can be expected during Hurricane Irma.

Getting Ready for Winter Looks Much Like Preparing for Hurricanes

Neil Sheehan
Public Affairs Officer
Region I

coldweatherAt first glance the blizzard that pounded the upper Midwest on Christmas weekend – or the winter storm that hit New England over New Year’s — doesn’t seem to have much in common with the hurricanes that hit the Gulf Coast or Eastern Seaboard during the hot summer months.

But from our perspective, they do.

NRC regulations requires that U.S. nuclear power plants be ready for all kinds of weather conditions, and that extends to winter storms.

The preparations take many forms. Here are some of the key activities:

  • Plant operators keep close tabs on approaching storms via weather forecasting services. Storm watches or warnings would clearly attract attention.
  • As a storm draws closer, information gathered from the facility’s meteorological towers is assessed. These data points would include wind speed/direction and snowfall rates. Specific conditions, such as wind speeds exceeding a pre-designated threshold, can result in operators starting to shut down the reactor, or reactors, at a plant site.
  • Prior to a storm arriving in the area, plant personnel would conduct visual inspections of plant grounds. They would check that there were no loose items that could be propelled by strong winds and potentially damage equipment.
  • Workers would also ensure that fuel tanks for emergency diesel generators were filled. These generators can provide back-up power for plant safety systems should the local electrical grid go down.
  • Plans would also be developed to keep the plant appropriately staffed until the storm had passed. This might mean providing cots and food for employees unable to get home due to the weather conditions.

Amid all of these preparations, the NRC Resident Inspectors assigned to each plant would follow the progress of these activities while also tracking expected conditions at the plant. They, too, could be asked to stay at the facility until the storm had passed.

The old adage that success is “90 percent preparation and 10 percent perspiration” is one taken seriously when wicked weather is bearing down.

 

Five Questions with Rick Hasselberg

Rick Hasselberg is a Senior Emergency Response Coordinator with the NRC’s Office of Nuclear Security and Incident Response.

  1. How would you briefly describe your role at the NRC?

5 questions_9with boxI manage the NRC’s Reactor Safety Team. If an emergency occurs at a nuclear power plant, my team is responsible for assessing nuclear facility conditions, predicting future conditions, and recommending actions the NRC might take to help protect public health and safety. I am responsible for recruiting, training, and continuously challenging the expertise and response readiness of one of the most respected emergency response organizations in the world.  What could be better than that?

  1. What is your foremost responsibility at work?

I think about emergencies. While 99 percent of the people working at the NRC are working hard to ensure that appropriate safety measures are in place, I work under the assumption that any of those safety measures could possible fail and that it’s time to get busy.  (The more I think about the things that might happen, the less surprised I will be if they do.

  1. What is your most significant challenge in the workplace?

rickh_fixedI struggle with competing demand for the agency’s best and brightest employees.  I must ensure that NRC will able to maintain a pool of experienced, qualified response team members who can be pulled away from their regular duties to train, exercise and, if ever needed, to respond to an actual emergency event.

  1. What do you consider one of your most notable accomplishments at the NRC?

I joined the NRC in late 1979, in the months following the Three Mile Island Accident. During that period, the NRC was under considerable pressure to improve both its internal training programs and its external public information (outreach) programs. I contributed significantly to both programs, introducing multimedia production techniques (film, video, and 35mm slides) for improving internal technical training, and I created and presented a highly acclaimed, day-long Nuclear Power and Radiation seminar that NRC presented to news media representatives throughout the United States. I was credited with helping to re-establish NRC credibility with the news media.

  1. What is one quality of the NRC that more people should know?

This agency has a lot of very smart, very talented people who really care about their role in serving the nation. I’m very proud to serve with them.

Five Questions is an occasional series in which we pose the same questions to different NRC staff members.

 

 

Hurricane Matthew and the NRC — UPDATE Part II

UPDATE 2:  The NRC’s Region II Incident Response Center was staffed throughout the weekend due to Hurricane Matthew. In all, three plants entered unusual event classifications for storm-related reasons, including electrical grid instability. In addition to the update below on the St. Lucie plant, two other plants, Harris and Robinson, experienced brief losses of offsite power due to the effects of the hurricane. At those two sites, the emergency diesel generators started automatically and provided power until the grid stabilized. — Joey Ledford

UPDATE: While our thoughts are with the people who lost power or suffered damages in the storm, the St. Lucie nuclear plant experienced winds below hurricane strength and did not lose off-site power. The plant’s safety equipment and systems were not affected by the storm and both units remain safely shut down pending a “Disaster Initiated Review.” The review will ensure that evacuation routes are clear and emergency services are available. The units cannot restart until that review is conducted jointly by the NRC and FEMA. The NRC continues to monitor Hurricane Matthew, and will decide later today whether to continue to staff its incident response center in Atlanta. — Joey Ledford

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.

pathDuring 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.
