Diablo Canyon earthquake vulnerability
Diablo Canyon (Nuclear) Power Plant, located on the water's edge in San Luis Obispo County California, was originally designed to withstand a 6.75 magnitude earthquake from four faults, including the nearby San Andreas and Hosgri faults, but was later upgraded to withstand a 7.5 magnitude quake. It has redundant seismic monitoring and a safety system designed to shut it down promptly in the event of significant ground motion.
==Introduction==
Diablo Canyon Power Plant (DCNPP/DCPP) is located proximal to the Los Osos, Hosgri, San Andreas and Shoreline faults. The discovery of these faults, late in the design process, required redesign. Construction errors compounded the delays and expense before the plant went online and began producing. Thereafter, discovery of the Shoreline fault caused a round of controversy leading Assemblyman Sam Blakeslee to introduce legislation mandating 3-D seismic studies. The Shoreline Fault is described in the November 2008 PG&E report as an "alignment of microseismicity subparallel to the coastline indicating the possible presence of a previously unidentified fault located about 1 km offshore of DCPP."〔http://www.pge.com/includes/docs/pdfs/shared/edusafety/systemworks/dcpp/2_SFZ_EXECUTIVE_SUMMARY.pdf〕 The plant is up for relicensing and, in the Fukushima aftermath, there is renewed opposition due in part to public perception that the risk of earthquake or tsunami make the plant unsafe. On the other hand, company officials contend that the plant is inherently safe from tsunami due its situation on an 85-foot coastal bluff. Re-licensing is contingent upon consistency with the Coastal Act and thus review by the California Coastal Commission, however seismic issues are more properly within the purview of the Nuclear Regulatory Commission. Much to the chagrin of some parties, such as U.S. Representative Ed Markey, the NRC in June 2011 announced that it had already completed its Safety Evaluation Report (SER) for the plant.〔http://pbadupws.nrc.gov/docs/ML1115/ML11153A103.pdf〕〔a4nr.org〕
