Independent Peer Review Panel

for Diablo Canyon Nuclear Power Plant

The SSC with many other state organizations, assisted the California Energy Commission in the development of a report in response to AB 1632 (Blakeslee) in 2008. The legislation directed PG&E to use advanced 3-dimensional seismic surveying and other methods to try to reduce the uncertainty in information regarding the plant’s seismic hazard. In 2011 The California Public Utilities Commission created an Independent Peer Review Panel (IPRP) consisting of the California Public Utilities Commission (CPUC), the SSC, the California Geological Survey, The California Energy Commission, The California Coastal Commission and a representative from the County of San Louis Obispo. The IPRP has been reviewing and meeting as warranted with personnel from the Pacific Gas and Electric Company and various interveners since 2011. The IPRP has been focused on reviewing seismic hazards with respect to the Diablo Canyon Nuclear Power Plant since the shutdown of the San Onofre Nuclear Generating Station.

The CPUC maintains a webpage with links to all of the IPRP reports and associated documents from PG&E.  The report from the California Energy Commission on AB 1632, issued in 2008, can be found at
