Diablo Canyon ground motion characterization model workshop update

On October 22-24, 2013, Pacific Gas and Electric Company (PG&E) and Arizona Public Service (APS) will conduct a three-day workshop with independent experts to develop a Southwestern Ground Motion Characterization (SWUS GMC) model. The model will be used to update the predicted levels of ground motions at Diablo Canyon Power Plant (DCPP) and Palo Verde Nuclear Generating Station (PVNGS) from earthquakes of varying magnitudes located at a range of distances from the sites. This is the second of three workshops that PG&E and APS are co-sponsoring in support of a Senior Seismic Hazard Analysis Committee (SSHAC) Level 3 study to update, in accordance with a directive from Nuclear Regulatory Commission, the seismic hazard characterization models for both plant sites. This October technical workshop involves seismic experts' evaluations of recorded ground motion data, ground motion prediction equations and ground motion simulations for integration of those data into the SWUS GMC model.


The public is invited to attend the technical portion of the workshop as observers. At the end of each day, there will be an opportunity for the public to ask questions about the topics discussed during the workshop.
