Map of earthquake faults underneath this nuclear plant

This was actually titled cynically as "El Diablo all cracked up" by the sender.
Articles accompanying this in one of our local press, New Times:
As for the reason a concerned citizen might justifiably jump down the NRCs throat for its lackadaisical oversight of nuclear reactors in general, and PG&Es Diablo Canyon specifically: In the fall of 2011, against the recommendation of one of the few inspectors who seemed to be asking the right questions, the NRC agreed to allow PG&E to eliminate two out of three of its seismic safety requirements because the company knew it couldnt meet them. Thats like the person administering the driving test for the DMV eliminating the requirement that I signal before turning because I dont know how to flick a blinker. Of course, lowering the standards at the DMV might result in a fender bender, whereas worst-case scenarios for Diablo involve everyone dying from radiation poisoning. Hopefully well all grow flippers first.
The timing of this decisiona mere seven months after the Fukushima disaster, seven months after the world realized what could happen if we dont take these things seriouslydoesnt do much to mitigate the impression that the NRC is once again bending over for PG&E, at everyones expense. Its actually not all that surprising that PG&E is playing dirty here. They are, after all, going to milk the taxpayers for every penny were willing to pay, for as long as were willing to pay, whether theyre using a nuclear plant that meets the most stringent safety requirements or not. The real villain is the so-called regulatory commission, which has become indistinguishable from PG&Es PR company.
PG&E chose not to do all three [tests] because its a waste of money, said one PG&E spokespersoner, I mean NRC branch chief. Its so easy to get the two mixed up sometimes. In fact, if you removed the attribution from Calculatory garbage (page 10), Ill bet you couldnt differentiate the PG&E spokespeople from the people being paid to oversee and regulate PG&E. Given whats at stake, thats a bit of a problem. Referring to tests that assess safety standards at a nuclear plant as a waste of money is bad enough if youre a PG&E employee. Coming from the regulator, its downright ludicrous. Throw in the fact that a PG&E supervisor wanted to use an NRC seismologist whos on our sideand in case youre dense, the our theyre referring to is not the ratepayer or the average citizen, but PG&Ein an argument with the one NRC inspector who actually seemed to take his job seriously, and the situation escalates from ludicrous to outrageous.

And
Did the NRC allow PG&E to dodge Diablo Canyon seismic licensing requirements?
BY MATT FOUNTAIN
Did Pacific Gas & Electric sidestep what some people consider to be critical seismic requirements for Diablo Canyon nuclear power plant following the discovery of the Shoreline Fault? Whether thats even a valid question to raise depends on to whom youre talking.
The U.S. Geological Surveys 2008 Shoreline discovery prompted PG&E to quickly assess whether the faulta roughly 12-kilometer-deep, 24-kilometer-long vertical strike-slip that intersects with the nearby Hosgri fault to the north, and lies some 600 meters from the plants power blockis capable of producing an earthquake large enough to damage vital plant components.
A subsequent PG&E report found that the Shoreline is capable of producing up to a magnitude 6.1 earthquake. The plant was built to withstand a 7.5-magnitude event.
But practical application of knowledge of the fault, as well as a hazy grasp on how it could interact with neighboring faults, turned into a years-long internal Nuclear Regulatory Commission debate focusing on the plants seismic safety design basis.
An operable plants safety components must be theoretically capable of functioning even after the impact from seismic events likely to occur at a facility given its known neighborhood hazards. Most plants have two design basis testing requirements to meet. Diablo Canyon is the only plant in the country required to meet three requirements: the Design Earthquake (DE), the Double Design Earthquake (DDE), and the Hosgri Event (HE). They differ by something called dampening assumptions, which are standards for how the plants components react to different ground motions. The DDE is considered the most conservative criteria, in that its the hardest to pass.

I am frankly stunned about the lack of concern about this by the entities who could do something about this, PG & E and the NRC.

Cleita
(75,480 posts)The fact is that there are two major faults and many others of varying degrees right under it and that is a fact. The plant can't handle an seismic event more than 7.5 magnitude.
FBaggins
(26,742 posts)People frequently misunderstand that, but the design basis earthquake for a nuclear plant is the level that it's designed to withstand without significant damage (i.e., returned to service a few weeks later after detailed inspections). It is not the level beyond which the plant "can't handle" it.
A pair of reactors in VA went through a beyond-design-basis earthquake a bit over a year ago... with essentially zero damage.
It would take substantially beyond a 7.5 to send the plant into meltdown... and 7.5 is already roughly ten times as powerful as the strongest quake that those faults are predicted to potentially deliver.
Cleita
(75,480 posts)Considering that magnitude 8 earthquakes are being witnessed across the planet due to global climate change, it won't be hard for one to hit here. We have already had in excess 6+ magnitude.

NickB79
(19,246 posts)Yes, I know that fluid injection through fracking is different from mass redistribution through global warming, but only a few years ago many people thought it was just as laughable that fracking and geothermal could generate earthquakes, much less one approaching a 6.0.

Do you have any idea what the difference is between a 6 and an 8?
Cleita
(75,480 posts)This plant is only a few miles from the San Andreas fault. Remember that one, the one that will cause the BIG ONE?

Remember that one, the one that will cause the BIG ONE?
You mean... the one that the plant was designed to handle?
This plant is only a few miles from the San Andreas fault.
50 miles is "a few" now?
Note that Fukushima was about that distance from the epicenter of a 9+ earthquake. It was closer to a 7 at the plant... and Diablo canyon was designed to handle without significant damage 2-3 times the ground motion that Fukushima was designed to handle.

(19,246 posts)Not as much by the earthquake.
Yes, the earthquake did create the tsunami, and did crack the foundation and containment structures that held the nuclear core. To this day, TEPCO still has to add water constantly to prevent the pools from running dry.
However, if there had been no tsunami (or if the generators were on an upper level of the facility), the backup generators wouldn't have been flooded out, and water circulation could have been maintained for cooling systems. The slow leaks through the subsoil foundation cracks could have been offset by increased pumping while the cores were removed to a more stable location. The nuclear reactors would have still been a complete loss, but no meltdown would have occurred.
So, not only must we know where the fault lines lie, and what size quakes they could produce, but if the reactor is in a position to be flooded by a tsunami. AND, if it is in position to be flooded, are the backup generators and related electronics protected enough/high enough up in the structure to keep working if a tsunami did hit?
Cleita
(75,480 posts)the tsunami that hit Japan also hit parts of the coast of California, including our port that is not far from the power plant. To minimize the danger is disingenuous of you.
NickB79
(19,246 posts)In order to generate a damaging tsunami, you not only need a powerful earthquake, but also the correct geography to focus and amplify the energy released by the earthquake.
Was your port devastated in the same fashion that the coastline of Japan was? Did a wall of water 10 ft tall slam into the shoreline and rush a mile inland? If not, why do you think that is? It's not due to the distance; the energy in a tsunami can propagate across vast distances in the ocean while retaining their energy: http://en.wikipedia.org/wiki/Teletsunami
I'm not minimizing the danger. I'm pointing out that A) the comparison between Fukushima and this reactor isn't accurate because of different geologic circumstances, and B) we need to consider MULTIPLE ways in which the reactor could fail. If, for example, there was no fault line under this reactor, BUT it was in a coastal area that could easily be swamped by a tsunami, it's still a real hazard that must be accounted for.
Cleita
(75,480 posts)I guess because there's a chance a large magnitude earthquake won't cause a tsunami, I guess it's okay then to ignore the danger that most likely it will?
NickB79
(19,246 posts)What I DID say is that we have to account for ALL the potential dangers in a given area, and prioritize them.
If an area on the West Coast doesn't have the geography to support a tsunami strike, the reactor is built 50 ft above sea-level, or it's backup systems are set high enough to avoid any flooding, then it's pretty stupid to waste large amounts of time and energy arguing about the risk.
However, I've never stated in this thread that we should ignore the danger of reactor damage from the earthquake itself. What I've been saying is that we can't compare the reactors in the OP directly to what happened in Japan, because of vastly different circumstances.
As I said in post #17:
What I DID say was that the specific incident the OP was referring to (Fukushima) would NOT have occurred if it were just an earthquake that struck the reactor.
Like I said, the cracks in the containment vessels from the earthquake would have guaranteed the plant would never function again, but the destruction of the generators by the tsunami is what caused the cores to go into melt-down. If those generators had remained functional, the plant could have been shut down in a controlled fashion and the radioactive rods removed safely.
I recognize the danger of an earthquake strike on a CA reactor. If large enough, it would permanently cripple the reactor. However, short of a quake so large that the entire facility itself crumbles to the ground, a meltdown like what we saw in Fukushima isn't likely.
FBaggins
(26,742 posts)It isn't just "big ones" that produce tsunamis... it's a particular type of big one.
A type that California isn't prone to and Diablo Canyon isn't at risk of. California has had LOTS of significant earthquakes... you haven't noticed that their version of tsunami isn't particularly dangerous?
(Of course... even if they were prone to them... being placed 85 feet up a cliff is pretty substantial protection)
Cleita
(75,480 posts)It's not like it's not going to be that bad if something goes wrong. It's that it will be devastating. It's not like a fire that destroys it and we rebuild. If there is a Fukushima disaster and all the makings are there, making it possible, there is no rebuilding for 50,000 years. Wake up!
FBaggins
(26,742 posts)That simply isn't the standard.
"If I can imagine it... we need to act on that risk!" simply doesn't make sense.
If there is a Fukushima disaster and all the makings are there
None of "the makings" are there except for the fact that it's a nuclear plant and you're scared of things that you don't understand.

(2,012 posts)Since 1945 the government has been trying to convince us that industrial nuclear power is warm and fuzzy (or at lease clean and safe). As compared to what? Maybe nuclear bombs. I thought after Chernobyl that thinking would change; instead more nuclear plants were built in the most "civilized" nations. I thought surely we would hear from the Japanese, the only nation that knows first-hand what nuclear power can do, after the earthquake and tsunami that would lead the world in closing plants and finding some way to dispose of all of that nuclear waste. Instead, their government too has tried to shut up their best scientists who want to shut down the industry. I thought surely California, our most earthquake-prone state, would be the first state to say "no more". But then I took for granted that Obama would make sure that no more nuclear plants would be built and no more bombs would be dropped.

Back in the day, if you wanted a well-paid job and didn't have a degree or connections, you worked for CMC or you worked for Diablo. Otherwise known as "winning hearts and minds".
An entire generation has now grown up viewing the emergency sirens as just another thing, without stopping to really think about what they are there to do. They won't think about it until something actually happens. Neither will the people in charge of the plant. It's sad.
Cleita
(75,480 posts)where they wouldn't have one. One is an engineer and the other a security guard. But they are quite aware of the problems. I believe at the time it was built, it was sold as a non-polluting way of generating energy. They didn't bother to inform people about the downside. Of course they wouldn't. Back then we didn't know much about solar and wind energy, so it seemed a better alternative to coal and oil. People were told it was perfectly safe and the earthquake faults not a big problem. Of course then two new faults were discovered after it was built and running. Also, a magnitude 7.5 quake back then was almost unheard of. Not so much today. So times have changed. We have alternative ways of delivering energy. Chernobyl and Fukushima have shown us just how unsafe and dangerous these plants are. It's time to decommission them, especially the ones over earthquake faults.
I do believe those workers who might lose their jobs can be given new jobs in the solar and wind industry.

(26,742 posts)Do you seriously believe that you get to make up your own version of reality and everyone else has to play along?
The big San Andreas earthquakes:
1680 - 7.7
1857 - 7.9
1906 - 7.8
None of 7.5 or greater since the plant was built.
The plant was built in the 1980s. The two largest earthquakes of the last century (Chile and Alaska) happened just a couple decades earlier. The one in Chile was 100 times larger than that "almost unheard of" 7.5
In short... as with so much of the thread... your claims have more basis in fantasy than reality.
