NRC to hold two public meetings on Diablo Canyon nuke on Nov. 28

The Nuclear Regulatory Commission will hold two public meetings on Nov. 28 to discuss topics including seismic issues and plant performance for the Diablo Canyon nuclear plant. The plant, operated by Pacific Gas and Electric Company (PG&E), is located near San Luis Obispo, Calif.

The NRC staff will hold two open house sessions from 1-3 p.m. and 6-7 p.m. during which subject matter experts will answers questions on topics related to current plant performance and the recently issued Research Information Letter in response to PG&E’s Report on the Analysis of the Shoreline Fault Zone.

From 7-9 p.m. the panel of subject matter experts will hold a question and answer session with the public to provide information and address public comments.

Both meetings will be held at the Embassy Suites Hotel, 333 Madonna Road, in San Luis Obispo.

In 2008, PG&E first notified the NRC about the Shoreline fault and then updated their data and analysis in early 2011. Following an Oct. 2011 site visit, the NRC review team analyzed ground motion from earthquakes the Shoreline Fault could potentially generate. All of those ground motions fell within Diablo Canyon’s existing design limits, which are based on ground motion associated with an earthquake from the larger Hosgri fault near the plant.

On Oct. 12, the NRC issued Research Information Letter 12-01, “Confirmatory Analysis of Seismic Hazard At The Diablo Canyon Power Plant From the Shoreline Fault Zone,” to communicate the results of the NRC’s analysis of PG&E’s assessment.
