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.

NRC Inspectors: Free to Inspect

Diane Screnci
Senior Public Affairs Officer
Region I

We often talk about having NRC Resident Inspectors at each commercial nuclear plant acting as the eyes and ears of the agency on site. It’s important to understand how they go about their business.

On a daily basis, resident inspectors are attending meetings, walking down equipment, monitoring major work activities, reviewing paperwork, and talking to control room operators and plant workers. When an event occurs at a plant, the resident inspectors are in the control room, watching how operators and the plant respond. They provide first-hand knowledge of what’s going on at a plant to regional management on an on-going basis. Inspectors often work business hours, but they’re required to work evenings, weekends and overnight hours, too.

NRC inspectors, including region-based specialists, have “unfettered access,” so they can go anywhere and watch any activity they choose. NRC regulations specify that NRC inspectors must have immediate unfettered access, although inspectors must comply with applicable access control measures for security, radiological protection and personal safety. That means if an inspector wants to enter a radiologically controlled area, he or she is allowed to, but first must follow the radiation protection requirements for the area.

“My job is to ensure the company is in compliance with our regulations and their operating license, which provides reasonable assurance that the plant is safe. One approach I use is the “trust but verify” method,” says Paul Cataldo, the NRC Senior Resident Inspector at Seabook Station in New Hampshire. “In essence, having access to any document, equipment or personnel on-site, without asking permission or the licensee having prior knowledge of a request, gives us confidence regarding the integrity of the information we use during our inspections.”

Plant workers are also prohibited from announcing that an NRC inspector is at the plant or in a particular area. It’s a violation of NRC requirements and over the years we have cited plants when workers tipped off their co-workers that inspectors were on-site.

We rely on our ability to perform announced and unannounced inspections to independently evaluate plant performance. Without unfettered access, our ability to carry out our mission could be impacted.

Projected End Date for Indian Point Plant Comes into Clearer Focus

Neil Sheehan
Public Affairs Officer
Region I

April 30th will mark a decade since Entergy submitted a license renewal application to the NRC for the Indian Point nuclear power plant. During the intervening years, thorough NRC staff reviews and a complex hearing on the proposal by the Atomic Safety and Licensing Board, the quasi-judicial arm of the NRC, have moved steadily forward.

indianpointBut then came an announcement on Jan. 9 by Entergy, the plant’s owner, and New York state. Under an agreement reached between the two parties, Indian Point Unit 2 would permanently shut down by April 30, 2020, and Indian Point Unit 3 by April 30, 2021. (Indian Point Unit 1 ceased operations in 1974).

This represents an earlier retirement of the reactors than proposed in the company’s license renewal application, which sought an extension of Unit 2’s operating license to April 2033 and Unit 3’s to April 2035.

Entergy cited the low cost of natural gas and rising operating costs as primary factors in its decision. The company said it would instead pursue a license renewal for Unit 2 to 2024 and for Unit 3 to 2025 to allow operation until then in the event the plant’s power output is still needed.

Company officials offered assurances that there would be continued adherence to safety requirements for the remainder of the plant’s operational life. NRC inspectors will be on hand to independently verify that all safety commitments are being met.

The NRC has three full-time Resident Inspectors assigned to Indian Point. We also send specialist inspectors to the facility to assess such areas as security, radiation safety and reactor operator training.

Agency staff will also have to complete their license renewal reviews and the hearing process will have to be brought to a conclusion. With respect to the latter, a motion to withdraw the remaining contentions in the hearing process is expected today.

It will be essential for Indian Point employees to maintain a strong focus on safety no matter the plant’s eventual end date. It will be incumbent upon the NRC to ensure that is occurring.

 

 

 

 

 

 

 

 

 

UPDATE: Protecting Commercial Nuclear Facilities from Cyber Attack

James Andersen
Director, Cyber Security Directorate

The NRC has been very forward-thinking in developing cyber security requirements for nuclear power plants. The cyber threat is always evolving, and so is our approach. We first imposed cyber security requirements in Orders issued after the 9/11 terrorist attacks. Drawing on our experience with those steps, we formalized regulations in 2009.

Our “cyber security roadmap” spells out how nuclear plant licensees were implementing our 2009 cyber regulations, as well as our approach to assessing cyber needs of other licensees.

cybersecNuclear plants are meeting these requirements in two phases. During Phase 1, they implemented controls to protect their most significant digital assets from the most prevalent cyber attack vectors. This phase was completed in December 2012, and our inspections of Phase 1 actions were completed in 2015.

During Phase 2, which will be completed by the end of this year, licensees will complete full implementation of their cyber security programs. They will add additional technical cyber controls, cyber security awareness training for employees, incident response testing and drills, configuration management controls, and supply chain protection

Like other NRC programs, cyber security involves “defense in depth.” Crucial safety- or security-related systems (both digital and analog) are isolated from the Internet, giving them strong protection. Such “air gaps” are important, but not sufficient. Licensees must also address wireless threats, portable media such as discs or thumb drives, and other avenues of attack. Physical security and access controls, including guarding against an insider threat to the plant, also add to cyber security, as do cyber intrusion detection and response capability.

The NRC published a new regulation in late 2015 requiring nuclear plant licensees to notify the agency quickly of certain cyber attacks.

With these efforts already accomplished or underway, you can see the NRC takes cyber security seriously, and we’re doing our best to stay flexible and ahead of the ever-changing threat. You can find more information about the NRC’s cyber security program on our website.
