Updating Seismic Hazard Analysis for Nuclear Power Plants in the United States

REGISTER

1:00 - 2:30 pm Eastern US Time

Nuclear power plants are built to withstand environmental hazards, including earthquakes. In evaluating the licensing of new plants in the central and eastern United States (CEUS), the industry recognized that new seismic hazard information has become available since many of these plants were designed and built as addressed in GI-199. The new seismic data suggests that although the potential seismic hazard at some nuclear power plants in the CEUS may have increased beyond previous estimates, but not so much as to need or warrant immediate action. The is generally an area of low to moderate earthquake hazard with few active faults in contrast to the western United States. Even so, in 1811–1812, three major earthquakes (Magnitude 7 to 7.7 on the commonly used Richter scale) shook much of the CEUS. These earthquakes occurred near the town of New Madrid, MO. In 1886, a large earthquake (Richter scale magnitude of about 7) occurred near Charleston, SC. Updated earthquake information will be as provided in the new EPRI/NRC/DOE studies associated with GI-199. Also, updated information has been evaluated by applicants in support of Early Site Permits and COLA’s for new reactors. This additional information included new models to estimate earthquake ground motion and updated models for earthquake sources in seismic regions in the CEUS.

This webinar will explore the processes and guidance used to evaluate the seismic hazards safety-significant structures, systems, and components being designed to take into account: More specifically, we will discuss issues likely to be considered by utilities and consultants responding to NRC’s expected Letter requesting responses to GI-199 expected in January 2012.

  • Expected changes in the shape of Seismic Source Zones in the CEUS
  • Expected changes in the Maximum Magnitude associated with the SSZ’s in the CEUS
  • Response Options for utilities with an existing operating plant and a pending COLA application for an adjacent Unit(s)
  • Will a utility need to have a new PSHA for an existing operating plant?
  • Will a utility need to have a new Probabilistic Safety Analysis run with new hazard curves or will an SMA be sufficient?

 

Any new nuclear plant the NRC licenses will use a probabilistic, performance-based approach to establish the plant’s seismic hazard and the seismic loads for the plant’s design basis. The webinar will also explore the implications of shifting to a risk-informed regulatory approach, including insights from probabilistic assessments and traditional deterministic engineering methods to make regulatory decisions about existing plants (e.g., licensing amendment decisions).

How It Works


 

After a live webinar is completed, we first have to tweak the audio settings to make sure the audio sounds okay; the recording will be available 24-48 hours later for your purchase.
Once Infocast has verified receipt of payment from you, an email will be sent within 24 hours containing the link to the recording and any available presentation materials.
You will be able to listen to the recording at your convenience, where ever you have an internet connection.
If you have any questions that were not answered during the recorded live Q&A session, presenters often include their contact information so that you may get in touch with them directly. If you don’t see any given during the presentation, please contact Emily Baker at This email address is being protected from spambots. You need JavaScript enabled to view it. and she’ll be happy to forward your question on to the presenters.

Single Connection: $245.00
Additional Connection at the same Organization: $150.00

A site connection allows a single connection to the web conference. That connection is open to any number of users in a collaborative setting. Because there are no travel expenses and only a single registration fee is required, each additional participant lowers the cost per participant significantly.

By purchasing a site connection, you can invite as many people as you would like to view and participate in the session from a single location. Set up the session in a conference room and project the presentation and chat on a large screen. You also have rights to distribute copies of the presentation materials to everyone involved. Please note that audio is received via the phone line and must be broadcast to your group.

If for any reason a relevant stakeholder cannot co-locate for the session, we encourage you to include that person by purchasing an additional connection at the reduced fee of $150 per session. This will ensure that every member of a team receives the same relevant, timely information in the most efficient way. If you have any technical or purchasing questions, please contact us at (818) 888-4444.

CANCELLATION, REFUNDS & CREDITS
Should you be unable to attend, a refund, less a $50 administrative charge, will be made for cancellations received via letter or fax at least 3 working days before the event. We regret cancellations will not be accepted after that date. However, we will be pleased to transfer your registration to another member of your company or credit the registration fee to another Infocast conference if you register within 6 months from the date of this conference. In the event the conference is canceled, Infocast’s liability is limited to the refund of the conference registration fee only.
