A Focus on NRC Annual Assessment Meetings

formal meetingIt’s Spring – and annual assessment meetings are popping up all over. The NRC holds these important meetings every year for every nuclear power plant to provide information about how the plant performed in the previous year.

What happens at these meetings? If you attend, you can expect to hear about NRC inspection activities, how the plant performed from a safety perspective, and how it met NRC requirements, including if there were any violations and, if so, what actions were taken to correct those issues. You would also hear directly from NRC resident inspectors, who are at the plant on a daily basis and know the plant inside and out. They and other specialists inspect the plant to help ensure protection of the public health and safety.

We just posted a short YouTube Video on the subject today. “Three Minutes with an NRC Expert on the Annual Assessment Meetings” can be found here.
community outreachAs the video underscores, annual assessment meetings are not all the same. There are different types, including a formal meeting, an open house and community outreach event. The most common meeting is a formal meeting where the public is invited to observe the interactions between the NRC and plant staff. Open houses are informal and are designed to encourage one-on-one conversations. An example of a community outreach event is where the NRC would staff a booth at a local event in an effort to talk to more folks. The type of meeting will vary depending on the plant’s performance, community feedback and local interest.

No matter the format of the meeting, the public will have an opportunity to not only hear about the plant’s performance and NRC inspection efforts but also ask questions, make comments and talk to the NRC staff.

A common misconception is that these meetings are transcribed — they are not. The basis for the NRC’s discussion is the annual assessment letters issued by the NRC to individual plants. These letters are documented and publically available. You can find them on the NRC website.

3 minutes with AA_1The NRC continues to reach out in an effort to inform people about what the agency does, how we regulate and how a particular plant is doing in meeting NRC rules and regulations. We are committed to protecting public health and safety, and strive to be open and responsive in these annual assessment meetings.

If you are interested in any upcoming public meeting you can check out the public meeting schedule and review the meeting notice as well as the press release.

We hope you’ll check out the video to learn more.

Throwback Thursday: Which Plant Is This?

NRC Inspectors Head to Indian Point 3’s Electrical Supply Room

Neil Sheehan
Public Affairs Officer
Region I

Dousing the fire that ensued after one of the Indian Point 3 nuclear power plant’s main transformers failed on the evening of May 9th required substantial amounts of water, as well as foam. The water was applied by the automatic fire-suppression system for the transformer and by the on-site fire brigade and firefighters from off-site who provided assistance.

indianpointOne of the follow-up concerns for the NRC is that during the event, some water was found on the floor of an enclosed room inside the plant housing electrical supply equipment. The power that flows through that equipment is used to operate plant safety systems and components.

The equipment was not affected by the water during the May 9th event, and the plant was safely shut down. The plant remains out of service while work to install a replacement transformer is carried out.

In order to better understand what occurred, the NRC is launching a Special Inspection at the plant today. The three-member team will evaluate, among other things, how the water – apparently totaling an inch or two on the room’s floor — ended up in the room; and the potential for a significantly larger volume of water to build up and adversely impact the electrical equipment.

The NRC applies risks insights and specific knowledge of plants when determining whether to perform a follow-up inspection and what type. In this case, the NRC decided it was appropriate to conduct a Special Inspection, the first level of “reactive” reviews performed in response to an event. The agency performs such inspections to independently evaluate and assess what occurred during an event, as well as any plans by the plant’s owner to fix related problems.

In addition to the Special Inspection, the NRC is continuing to review the transformer failure, operator and equipment response during the event, and other issues.

A report containing the findings of the Special Inspection will be issued within 45 days after the formal conclusion of the review.

Throwback Thursday – Name the Scientist

Chemist Glenn Seaborg stands next to a periodic table. He is pointing at the synthetic element seaborgium, which is named after him. Dr. Seaborg, a former Chairman of the Atomic Energy Commission, was awarded the Nobel Prize in Chemestry in 1951.

This scientist is best known for discovering an important element, as well as winning the Nobel Prize in Chemistry. His other claim to fame – and the one he apparently cherished most highly – was having an element named in his honor. What was the scientist’s name? What element did he discover and which one was named for him?

Indian Point Transformer Fire

Diane Screnci
Senior Public Affairs Officer
Region I

NRC inspectors are following up on a transformer fire at Indian Point Energy Center over the weekend. The NRC Resident Inspectors for Indian Point – who work at the plant on a daily basis – are monitoring activities at the site while plant workers are troubleshooting and looking for the cause of the fire on the Unit 3 main transformer.

The transformer fire happened at about 6 p.m. on Saturday night. A sprinkler system initially extinguished the flames, but it reignited and was put out by the onsite fire brigade and local fire departments. The fire caused the reactor to automatically shut down, as designed. All safety systems worked as designed. There was no danger to the public and no release of radiation. The reactor is stable. Unit 2 continues to operate at full power.

Plant operators declared an “unusual event” – the lowest of the emergency classifications – in accordance with plant procedures. All plants have procedures, approved by the NRC, that dictate how events are classified to ensure appropriate steps are taken to respond to the event and to communicate the event to local and state agencies and the NRC.

In addition to cooling provided by fans, the main transformer is also cooled by oil flowing through it. On Saturday, oil from the transformer spilled into the plant’s discharge canal. Entergy has been working to determine how much oil was spilled.

The transformer that failed carries electricity from the main generator to the electrical grid. The same type of equipment can be found at any plant that generates electricity. It is on the electrical generation side of the plant – not the nuclear side.

As far as next steps go, plant employees will determine what happened and why. They will repair or replace any equipment that was damaged in the fire. The plant can restart when ready. NRC inspectors will be monitoring Entergy’s actions every step of the way, ensuring workers are taking all appropriate actions.

As we do with any event at a plant, we’ll continue to review what happened and how the plant responded. If need be, we’ll send additional inspectors to the site to look further into the event and its effects.
