Ironically, as America’s Nuclear Regulatory Commission (NRC) allows Diablo to operate, all 54 reactors in Japan remain shut. Its Nuclear Regulatory Authority has just ordered the Tsuruga reactor to be scrapped because of its vulnerability to earthquakes. Two more elderly reactors at Mihama may also be terminated before year's end.

Similar defects remain uncorrected at Diablo Canyon, whose radioactive cloud could span the continental U.S. in four days. Mass citizen action recently shut two coastal reactors at San Onofre . It must do the same at Diablo before the next quake hits.

The California Public Utilities Commission (CPUC) has just proposed that PG&E be fined $1.4 billion for a 2010 gas explosion and fire that killed eight people and obliterated a neighborhood in San Bruno. The federal government has announced 28 indictments, meaning the CPUC fine may just be the tip of a very expensive iceberg for PG&E. The San Bruno disaster was caused by pipeline defects about which PG&E had been warned for years, but failed to correct. The fines cover 3,798 separate violations of laws and regulations, both state and federal. PG&E was previously fined $38 million for a 2008 pipeline explosion in Rancho Cordova.

A 42-page report from NRC inspector Dr. Michael Peck says new fault line discoveries challenge Diablo’s “presumption of nuclear safety.”

Diablo's owner, Pacific Gas & Electric (PG&E), is in deep legal and financial crisis.

They are riddled with defects , can’t withstand potential seismic shocks from five major nearby fault lines, violate state water quality laws and are vulnerable to tsunamis and fire.

The next west coast quake could easily shake the two reactors at Diablo Canyon to rubble.

The catastrophe at Fukushima was not an accident. It’s unfolding again in California.

At Fukushima, Tokyo Electric Power now admits that far more radiation is spewing into the Pacific than previously admitted. The thyroid cancer death rate among children in the area is 40 times normal. So is the still-rising childhood thyroid abnormality rate, a terrifying re-run of downwind Chernobyl.

Tepco has begun paying compensation to local suicide victims, including the widower of a woman who doused herself with kerosene before burning herself alive.

All of it predictable.

For decades Japanese citizens warned Tepco not to build reactors in an earthquake/tsunami zone. The company repeatedly ignored safety warnings and tolerated known defects that worsened the disaster.

Diablo Canyon’s twin reactors sit eight miles west of San Luis Obispo, between Los Angeles and San Francisco, surrounded by earthquake faults.

The Hosgri, three miles offshore, was found as the reactors were being built. Design specifications were never fully altered to account for it. Nor have they been upgraded for the newly-found Los Osos, San Luis Bay and Shoreline faults. The Shoreline lies just 650 yard from Diablo’s cores.

The massive San Andreas fault is just 45 miles away, about half as far as was the March 11, 2011, Richter-9.0 epicenter from Fukushima.

A shock that size from any of the fault lines near Diablo could reduce it to a seething pile of radioactive hell, far deadlier than Fukushima. Prevailing winds could blanket virtually all of North America with its deadly fallout.

The nuclear industry would immediately deny all health impacts. It would blame “unpredictable” God and nature.

But a 42-page report from NRC inspector Dr. Michael Peck says new fault line discoveries challenge Diablo’s “presumption of nuclear safety.”

Buried by the NRC for at least a year, it was released by Friends of the Earth and reported on by the Associated Press and the great enviro-journalist Karl Grossman, as well as by the Nuclear Information & Resource Service and Beyond Nuclear.

Peck has a doctorate in nuclear engineering and was Diablo’s chief on-site inspector for five years. He’s now a senior instructor at the NRC’s Technical Training Center in Tennessee. His status as a current NRC employee makes such a critical report highly unusual—and alarming.

Nuclear engineer Arnie Gundersen has warned about sea-level intake pipes like those at Diablo. When the tsunami struck Fukushima, he writes, “The cooling equipment along the shoreline was turned into a scrap yard of twisted metal.”

Then there is fire.

Diablo Canyon, writes David Lochbaum of the Union of Concerned Scientists, "has never, ever complied with fire safety regulations, not even for a second by mistake."

“The one-two punch of earthquake/tsunami caused Fukushima," Lochbaum wrote in an email to me.

"A one-two punch of earthquake/fire could cause Diablo Canyon.”

But, says Lochbaum, “It can't be an accident. Not when the company and its alleged regulator both know that the plant does not met earthquake and fire safety regulations.

“That cannot cause an accident. Criminal negligence perhaps. At least malicious mayhem. But not an accident.”

More than 10,000 people were arrested trying to stop Diablo in the 1970s and ‘80s. During the delays they caused, PG&E found major errors in reading key blueprints involving some of Diablo’s most critical equipment.

Damage is still being tallied from California’s Aug. 25 Napa Valley quake. The 1994 Northridge quake killed 57 people, injured roughly 5,000. The Loma Prieta quake during the 1989 World Series killed 63 people, injured more than 3,700. The infamous 1906 San Francisco quake leveled the city and killed thousands.

New shocks at Diablo Canyon could dwarf all those numbers—and Fukushima’s.

Tens of millions of Americans would be irradiated. Our continent's eco-systems would be poisoned. Our nation's economy would be gutted.

But as at San Bruno, there would be no excuses.
