A Fukushima-Sized Problem
A newly-exposed report by Diablo Canyon's lead nuclear inspector shows that the twin reactors are unsafe, writes Karl Grossman. An earthquake on nearby geological faults could trigger a Fukushima-scale accident causing 10,000 early fatalities. The owner's response? Apply to extend the site's operation for another 20 years.
As aftershocks of the 6.0 Napa earthquake that occurred Sunday in California continued, the Associated Press revealed a secret government report pointing to major earthquake vulnerabilities at the Diablo Canyon nuclear plants which are a little more than 200 miles away and sitting amid a webwork of earthquake faults.
It's apparent to any visitor to the stretch of California where the two Diablo Canyon plants are sited that it is geologically hot. A major tourist feature of the area: hot spas.
"Welcome to the Avila Hot Springs", declares the website of one, noting how "historic Avila Hot Springs" was "discovered in 1907 by at the time unlucky oil drillers and established" as a "popular visitor-serving natural artesian mineral hot springs."
Nevertheless, Pacific Gas & Electric had no problem in 1965 picking the area along the California coast, north of Avila Beach, as a location for two nuclear plants.
It was known that the San Andreas Fault was inland 45 miles away. But in 1971, with construction already under way, oil company geologists discovered another earthquake fault - the Hosgri Fault, just three miles out in the Pacific from the plant site and linked to the San Andreas Fault.
In 2008 yet another fault was discovered, the Shoreline Fault - just 650 yards from the Diablo Canyon plants.
The Shoreline Fault, and concerns about the vulnerability of nuclear plants to earthquakes in the wake of the 2011 Fukushima Daiichi disaster, are integral to a 42-page report written by Dr. Michael Peck.
