NRC – DIABLO CANYON POWER PLANT, UNIT NOS. 1 AND 2 -NRC PRELIMINARY REVIEW OF POTENTIAL SHORELINE FAULT
On November 14, 2008, Pacific Gas and Electric (PG&E, the licensee) notified the U.S. Nuclear Regulatory Commission (NRC) that preliminary results from ongoing studies by PG&E and the U.S. Geological Survey (USGS) indicate that there is a zone of seismicity that could indicate the presence of a fault approximately 15 kilometers (km) in length, located approximately 1 km offshore from the Diablo Canyon Power Plant (DCPP). Subsequently, PG&E has informally referred to this zone of seismicity as the potential “Shoreline Fault.” PG&E has been collaborating with the USGS to collect and analyze new geological, geophysical, and seismic data to develop improved tectonic models for the central California coastal region through the Collaborative Research and Development Agreement. . .
