RE: California's avoidable risk??? Shut-down is the most important next step!
Dear Readers,
Below (top) is an email today from the "Union of (Un-)Concerned Scientists" ("UUCS") asking us to support urgently moving the nuclear waste currently being stored at California's nuclear reactors from spent fuel pools to on-site dry cask storage.
Maybe you've heard me say it before, but I'm going to say it again anyway: Dry casks are not the solution! Shutdown is!
Let's start with a correction to their letter: Dry casks are NOT "transportable" as their letter states. The fuel will have to be moved from the storage cask to a transport cask, and every transfer runs a significant additional risk. They are NOT making "transportable" dry casks at ANY reactor site that I know of, and certainly not at SanO or DC.
And let's say they start transferring and transporting this stuff and even get "good" at it. If it becomes routine, THAT runs a risk of complacency!
And don't forget: Every 80 or 100 years or so, starting several generations after providing any benefit whatsoever, someone will have to somehow take the still-highly-radioactive dried out embrittled reactor cores and transfer them to NEW dry casks, because, it's widely assumed, Yucca Mountain still won't exist (and shouldn't; it's not a safe solution either).
Multiple, dangerous transfer operations can be avoided if we leave the spent fuel in pools.
The real purpose of dry cask storage is to give the industry a way to keep going without having to spend up to approximately half a billion dollars each for new spent fuel pools, which keep the fuel properly separated, and under 40 feet of water.
There are three things you desperately want to avoid with spent fuel.
One is getting near it. The intense gamma radiation and other radiation the fuel emits would kill you in seconds, and that will be true for eons. The fuel must be heavily shielded from humans and animals the entire time.
Another thing you want to avoid is a zirconium cladding fire. All spent fuel needs is a spark. The zirconium can even ignite spontaneously under certain conditions. Perhaps ALL of the casks at SanO will burn, one after another down the line, or at least the three that are stacked one on top of each other will all burn if one does, and their fission products will all be released.
The third thing you want to avoid, of course, is a "criticality event" (uncontrolled chain reaction).
To avoid the first problem you want to keep far away from the fuel and/or have it be heavily shielded -- several feet of concrete and several inches of steel and lead, or 40 feet of water will do for "industrial" sites (but even that is not nearly good enough for the public).
If a fire starts, you will not be able to get close enough to douse it with water later, and nor would it do any good. Better to keep it wet from the start and avoid the spark.
However, avoiding a criticality event means you want to keep as little of the spent fuel in one place as possible. Does that mean dry casks? Or smaller pools? Pools are vastly more expensive. But aside from that, which is better?
The fact is: Nuclear waste management costs money. Lots and lots of money. And the more waste you have to manage, and the safer you desire it to be, the more costly it will be.
Calling dry casks "much safer" than spent fuel pools, as the UUCS does below, is debatable at best, and disingenuous at worst (we'll just debate it). But more importantly, the question ISN'T one or the other. It's: Do you want BOTH? Or should we stop making (more) spent fuel instead? The answer is obvious: Close the reactors. Keep those that are closed, closed forever.
Just because you have, say, 33 dry casks at a site doesn't mean 34 isn't MUCH more dangerous. It's about 3% more dangerous, and that's a lot of added danger. But it won't stop at 34, or 68 or 136. Dry casks can just keep going until something goes very, very wrong.
Where is UUCS's call for shutting down SanO and DC forever? How come THAT's not suggested as a BETTER way to reduce the risk, instead of letting it increase day by day by day?
What about the risk SoCal residents just went through last January, from the busted up steam generators, which could have cascaded into a catastrophic meltdown? Are we simply waiting for an American Fukushima? Are we waiting for California's "Big One" (with hot sauce)?
San Onofre is currently shut down because its steam generators are busted.
But that's not all that's wrong. It's fuel pools are full. It's in a tsunami inundation zone AND an earthquake zone. It's old and decrepit. It's employees are intimidated by management and falsify reports and are afraid to report safety problems. Management likewise has its back against the wall and is desperate to prove they can restart the reactors somehow, despite the engineering logic against such a thing. Nobody wants to lose face or their job. Every state agency claims only the Nuclear Regulatory Commission can "force" San Onofre to close, and the NRC never met a nuclear power plant it didn't like.
The citizens who don't want Fukushima USA to happen here are in a bind, that's for sure. But dry casks aren't the solution. Shut-down is the most important and only logical next step.
Sincerely,
Ace Hoffman

Here are some additional comments from a friend:
If dry casks have a weak point then you can bet terrorist groups will find a way to exploit it. They weaponized our airline industry and I am sure they have already have ideas to weaponize spent fuel in ways that we have not conceived of yet. These pools and casks are some of the largest repositories of nuclear material in the world and our government has allowed these stockpiles to be unsecured. Why in the hell would the NRC allow that to happen?
There are open pits in the New Mexico desert containing radioactive waste from Los Alamos sitting in the open under tarps, that was vulnerable to the brush fires that swept through the area in June 2011. Staff from Los Alamos were visibly worried on the news as the fires spread throughout the area where the waste was stored. This was a sign to me that the industry has no regard for risk assessment.
I worry that the temporary solution of dry casks will become the long term solution as the public becomes complacent and casks are left semi-abandoned by the industry on shuttered nuke sites that have to be secured by the DOE or the military. They may have to remain indefinitely but http://dspace.mit.edu/handle/1721.1/52363 shows that even concrete is not a totally stable material.
http://www.redorbit.com/news/technology/1705874/the_lifespan_of_concrete/ This article states that containment vessels for nuclear waste are made today to last 100 years. That's about 100,000 years less than what is needed.
And this faith in the longevity of concrete to encase spent fuel is still speculation, not practice with tested outcomes. This article about the MIT study speculates the longevity of high density concrete at 100s of thousands of years. But no one knows as steel reinforced concrete is a relatively new synthetic composite. http://journals.cambridge.org/action/displayAbstract;jsessionid=2B23FD6B00CA83363B2A8CC76EF4E48F.journals?fromPage=online&aid=8112003 In an above ground configuration such as dry cask hardened enclosures, the elements will play a part in the longevity of the material. Remember that we are talking about tens of thousands if not hundreds of thousands of years that these structure must last.
Stainless steel will have its inherent weaknesses over time as well. Just one bunker-buster from a Chinese or Russian stealth fighter, in the future, would answer the dry cask safety question.
Portland cement was used to build most of the modern world yet we do not know how long those structures will last. Ironic isn't it that the only thing that our civilization has created that we know will last for an eternity is deadly nuclear waste.
###
I left the following comment at HuffPost in response to a dry cask article by UUCS there:
Dry casks are no solution. Shut down the reactors, it's the only solution. Where do you put something that mustn't catch fire, no matter what? New spent fuel pools would cost about half a billion dollars to build, plus maintenance. Dry casks are vastly cheaper. THAT is what is driving the push to dry casks -- NOT "safety". What is anyone going to do if/WHEN a dry cask catches fire (shall I list two ways that can happen? Terrorism and accidental airplane strikes, but there are plenty of others....)? Just say no to nuclear power. www.acehoffman.org

Five fundamental, unrepairable, fatal flaws at SanO...
>ace, is this really the case that san onofre came close to blowing? [see below for the comment she was responding to]
6/18/2012 Dear Readers, On January 31st, 2012 San Onofre came a lot closer to meltdown than should ever be allowed. The steam generator tube that failed could have flung into another one and another one, in a cascade of failed tubes (David Lochbaum made the statement that this could happen first, back in February I believe, and Arnie Gundersen has backed it up [pointing out the pressure difference between the inner and the outer loops is about a 1000 pounds per square inch]). A cascading failure would have done two things: 1) Destroyed one of only two steam generators, "vital" (NRC's word) to remove decay heat from the reactor (most PWRs have more than two SGs), and 2) Thrown metal shards throughout the system, blocking water flow paths, valves, and piping. Enormous losses of primary coolant would have resulted in large radiation releases and a "large break LOCA" would be in progress -- (LOCA = Loss Of Coolant Accident). Could SanO still survive? Sure -- if the never-tested ECCS (Emergency Core Cooling System) worked as designed -- but the sump pumps have been a problem there -- they apparently can get clogged with debris [thank Lochbaum again for pointing this out]. And nobody really knows if an ECCS would work at all, especially with BOTH SGs broken. (The flying metal shards from one could damage the other, leading to TWO cascading SG tube failure situations.) Numerous backup systems that have failed tests or been improperly inspected year after year would be called into play. Thousands of tubes in each SG had been significantly weakened by the time one ruptured. Blocked flow paths within the reactor could lead to core melt in a matter of seconds. Sincerely, Ace Hoffman, Carlsbad, California USA (images added 2025)
FIVE FUNDAMENTAL AND UNREPAIRABLE FLAWS AT SAN ONOFRE:
1) It generates fission products such as cesium and strontium, as well as plutonium, tritium, and other radioactive byproducts. There is not, and never will be, a safe and cost-effective containment for these materials. They are generated in vastly larger quantities than can be safely managed -- 500 pounds per day at SanO, when it's operating (hopefully, never again). 2) SanO is decades old. Parts are rusted, corroded, embrittled, worn out, worn down, worn through. A portion of a 24-inch diameter pipe for the Emergency Core Cooling System had to be replaced recently because its clampdowns had rusted through -- two inches of metal gone. Why wasn't the problem discovered sooner? Improper inspection procedures! About the only thicker piece of metal in a reactor is the reactor pressure vessel itself (about 8 inches). And Unit II's RPV head had rusted away so much it had to be replaced last outage, and I believe Unit III's RPVH has also been, is being, or will soon be, replaced. The Davis Besse reactor nearly melted down in 2002 due to age/rust/negligent maintenance procedures. The whole eight inches of steel had been eaten away there, and only a stainless steel liner remained -- and it was bulging outward. SanO is also rusting away. 3) SanO has two Steam Generators per reactor. This is a flawed design because it leaves so little backup for heat removal if one of them fails catastrophically. 4) A bad work environment is inevitable at San Onofre because it IS falling apart and there ARE numerous things to complain about, and the public SHOULD be up in arms about what is happening there, and WILL get that awful plant closed sooner or later. But they don't like being told to close, so they cover more and more stuff up as the activists get more vocal. Which means the sooner we succeed, the safer. Because the least safe thing to do would be to ignore the danger, even if complaining alone actually makes things even less safe. There is no other way. 5) The Big One is coming to California, and nobody needs another study to know it. We'll lose thousands of lives when it comes, mostly the poor souls who will be caught in improperly-built building collapses, and people who try to run out of buildings instead of getting in doorways, and get hit by falling debris. We don't want radiation victims added to our problems that day. We don't want permanent evacuations because of the fallout. We don't want "shelter in place" as the deadly clouds drift over us. We'll have other problems and would like a distributed, reliable energy source so that after The Big One, we can get power back again quickly. SanO will go down at the first sign of a shake IF everything goes well, and won't come back up for weeks. That's assuming it was running in the first place, of course. There are many other "fatal flaws" of nuclear power generally and San Onofre in particular. It should be decommissioned immediately and forever. ###
Original message:
Subject: Definitely maybe: NRC admits it messed up at SanO really badly... 6/18/2012 Dear Readers, In eager anticipation of today's hearing in San Juan Capistrano, AP has released an "exclusive" report -- that says virtually nothing! The closest thing that comes to a new statement is where the speaker is definitive, and then immediately takes it back: "The phenomenon that we think causes this tube-to-tube interaction is definitely proportional to the power," Collins said. "At least in some theoretical sense, that might be part of the answer." More interesting is that Collins -- that's Nuclear Regulatory Commission Region IV Administrator Elmo "Ask Elmo, he won't tell you" Collins -- admits there were "significant" design changes to San Onofre's steam generators -- therefore admitting they were NOT "like for like" and the NRC had been seriously hoodwinked by the utility. Will they fine themselves for being negligent and nearly costing SoCal a nuclear meltdown similar to what happened at Fukushima? Because that's what actually happened. We almost lost SoCal. Will people go to jail for their negligence, greed, and dishonesty? No, of course not! We don't live in a dream-world where the wicked are punished and bad deeds are undone. We live in the real world, where cover-ups are followed by cover-ups of the cover-ups, whitewashed explanations, and more business-as-usual.

18 steam-generator-specific questions for SCE/NRC
I just sent this to the facilitator for the upcoming NRC meeting on Monday....
Ace
To: "Richard Daniel, Facilitator" <Richard.Daniel@nrc.gov>
6/15/2012
Dear Sir...
[Regarding the upcoming hearing on San Onofre] my main concern is not so much that a "root cause" has been discovered or even that the trail [is laid out] of how such significant changes were purposefully slipped past the Nuclear Regulatory commission (see attached comments documenting this by Ray Lutz, a local engineer who will be appearing at the hearing on Monday). Mr. Lutz's concerns about procedural breakdown are significant not only to the NRC's method of operation, but to any highly-regulated industry. With regulation tends to come a willingness not to see what is NOT in the regulations, or not brought to one's attention through the normal regulatory channels. The standard answer from the NRC to this citizen has always been "we'll get back to you" -- and that's the end of it.
My main concern is not the "root cause" because I believe it's going to be that the upper area of the steam generators do not have enough water and have too much steam, proportionately, because of a redesign of a plate which blocks more water than the old design did, as the water/steam mixture rises inside the massive steam generators. The water acted to dampen vibration in the old design, hence in the new design, the thin, closely-packed tubes clang into each other. This concept was presented by Arnie Gundersen along with a concern about vibration in the base plate, which I believe may also be a contributing factor. If it has turned out to be something else entirely, that will be of some interest, and I will be interested to see the evidence which supports any alternative theories.
However, my concern is entirely going forward and thus, I refer to such problems as tsunami dangers brought on by underwater landslides, caused by earthquakes in the nearby vicinity of the reactors (within a few hundred miles, for example). The San Andreas fault is approximately 99% certain to have a tremendous rupture in the next few decades. Many of the other faults in the area are expected to reawaken after that event, too -- and new ones will be discovered, no doubt. I find this chilling.
There is virtually indisputable geological evidence of massive tsunami events in THIS coast's past; probably caused by underwater landslides somewhere. Add to that the "unexpected" size of the earthquake in the most earthquake-studied area of the world last year -- that led to the tsunami and triple reactor meltdown in Japan, and I see no reason to wait for another earthquake study -- even if it's getting $64 million in funding (of our money) and will take half a decade or more to complete, it's going to be so thorough. Can we afford to wait? Could Japan? Expert scientists can already dispute the entire effort, if it's findings are anything different that what I have just described as a possible worst case scenario: Events far larger than SanO can possibly survive. That's what we risk if the "root cause" is found and fixed, and the reactors are returned to service. Frankly I'd rather the NRC NOT find the root cause, if that's what it takes to keep the reactors closed! We were promised, however, that at least the root cause would be determined. (I would say the root cause was greed on the part of San Onofre's operators, and that is still present and cannot be accounted for.)
The 2004 earthquake/tsunami combo that killed about a quarter of a million people, and the fact that the tsunami was caused by an undersea landslide made such events prominent in the news. A reactor thousands of miles across the Indian Ocean in India was in fact, damaged by that event, but because it survived, and because none were close enough to be destroyed, the obvious threat was ignored. Come 2011, the price of ignoring the threat fell due for Japan. Perhaps the day after restarting San Onofre, the price of ignoring history will fall due for California.
These are not irrelevant to the steam generator issue by any means, because the steam generator issue causes the local population to bleed money into Southern California Edison's coffers and risk catastrophic meltdowns in return. It is a bad investment ON TOP OF a bad investment! So it won't merely take making the steam generators work better to fix the problem.
As a noted early pioneer of nuclear reactor design noted later in life: "The most intolerable reactor of all may be one which comes successfully to the end of its planned life having produced mountains of radioactive waste for which there is no disposal safe from earthquake damage or sabotage." (The late Dr. A. Stanley Thompson, nuclear physicist.)
So there is no way to exclude the rest of the world's problems from the steam generator decision. To replace them with PERFECT steam generators would still be hazardous to our health and we don't want them.
That said, I would still like some technical questions answered regarding the steam generators, and have included 18 of them below. Arnie Gundersen, who was involved in the basic design of steam generators within the nuclear industry and whom you already are aware will be attending Monday's hearing, has already seen the list of questions, and suggested one of them himself. (I'll leave it to the team to guess which one. :~} )
I hope that written answers can be provided to me in addition to any comments that might be made at the hearing. I appreciate the continued professionalism of the many NRC inspectors and officials I have dealt with over the ~two decades that I have been attending hearings regarding San Onofre and other nuclear issues. I look forward to hearing from you.
May the whole truth win...
Best regards,

1) Which tubes needed to be plugged? Were they all in one area, inner, outer, or scattered?
2) Have any changes been made to the design of the SGs to allow the units to work, other than plugging tubes?
3) How many tubes were plugged?
4) What are the primary and secondary coolant loop pressures, flow rates, and temperatures that SCE proposes to run at, given that the power outputs are "50% to 80%" of normal. For 50%, what are the numbers, and for 80%, what are the numbers? (Normal is about 1200 PSI in the secondary loop and 2200 PSI in the primary loop, for example.)
5) What vibration sensors, temperature sensors, and other sensors have been added to ensure that problems are being found, and what vibration sensors, temperatures sensors, and other sensors were in place before?
6) How frequently will the reactors be shut down for additional inspections?
7) What if a rupture/leak occurs before the first inspection? Will the "experiment" with our lives be ended once and for all at that point?
8) What is the amount of wear on those tubes that have shown wear?
9) Even if thousands of tubes have been plugged, they are still vibrating and are still worn. How can it possibly be safe to operate the reactor with so many weakened tubes?
10) Given that these were new and most of the reactor is 30 or more years old and rusted out and decrepit, why not just give up?
11) What % of the wear was caused by tube-to-tube interactions and what % was caused by tube-to-support interactions? How much damage was near the bends of the U-shaped tubes?
12) Could the additional vibration of the tubes throughout the structure also cause additional wear at the base of each tube -- their sole place of firm attachment? Has this been examined or even considered? The vibration could help work the crud that naturally gathers there work deeper into and between the metals. Would this wear show up right away or will we find out later when tubes start to pop out of their holes?
13) Will operating at reduced pressures, temperatures, and/or flow rates actually cause an increase in metal-damaging deposits not only at the base of each tube but throughout the system, as the "natural flush" that they had been designed to operate with would no longer be occurring?
14) Will SanO be required to shut down immediately upon detecting a leak in the steam generator tubes, or will they be allowed to continue to operate, as long as the leak rate from the primary loop to the secondary loop remains below the normal daily limit for all Pressurized Water Reactors (which I think is about 85 gallons a day)? Will they be given a stricter limit than usual in light of their pressure test failures and actual failures thus far? Or will they be given a more relaxed limit, instead?!?!
15) Considering the increased risk, what is the advantage of letting SanO operators continue to run the plant even after they know they have a leaky situation? (I presume the "advantage" is that very small leaks tend to self-seal with crud; that's why they are allowed to run with continual leaks; it's only the "growing" ones they really worry about, but would like this confirmed.)
16) Given that SanO only as two SGs per reactor, instead of the usual three or four like in most other PWR reactors, the importance of having operational SGs is much greater than at other reactors, because when one fails, there is only one left for heat removal. The new SGs are clearly improperly designed, and to the effect that there are only two, the entire design is clearly faulty and should be abandoned. Why not abandon an obviously-inferior design?
17) The ISO, FERC, SDG&E and SCE have all said we should NOT expect blackouts even in the worst summer days just because SanO is down. Even if we do have any, it's better than having meltdowns -- which might well happen if SanO is brought back online with faulty steam generators. Why generate more nuclear waste and risk catastrophic failure?
18) Why did Edison plug 1300 tubes when their ultrasonic/ eddy current tests indicated that only 12 needed to be plugged?

FOR IMMEDIATE RELEASE
Activists Demand Nuke Plant Closure at NRC Public Meeting
Nuclear Regulatory Commission to Release investigation findings on San Onofre June 18 in San Juan Capistrano
Ratepayers Demand that Edison CEO Craver Shutter Troubled Plant
June 14, 2012 (SAN JUAN CAPISTRANO) The public will rally and sponsor a press conference in opposition to continued operation of the San Onofre nuclear plant on Monday, June 18, at 5pm prior to the 6pm public meeting scheduled by the Nuclear Regulatory Commission (NRC) at the San Juan Capistrano Community Center at 25925 Camino Del Avion, San Juan Capistrano, California.
After months of investigation, the Nuclear Regulatory Commission will hold its first public meeting after the emergency shut down of the San Onofre Nuclear Generating Station on January 31, 2012, and after their official investigation into the steam generator failures.
"Unfortunately, the NRC wants to limit valuable public input by withholding their report until they announce it at the meeting, making it difficult to the public to formulate questions on this technically complex issue," said electrical engineer Ray Lutz, National Coordinator for Citizens' Oversight Projects. "This is the first public meeting where the public will have a chance to speak and ask questions. It's too bad they're making this like a pop-quiz instead of a take-home test."
Activists are concerned that the NRC will deliver a token report on what occurred, followed by a "we'll have to study your report" response by the utility. NRC Chair Gregory Jaczko, the sole dissenting voice on the commission, recently announced his resignation, signaling that the commission would likely turn into a rubber stamp for utility wishes.
Edison Chair Theodore F. Craver, Jr. admitted that it really was his decision alone to decommission the plant, and that it would be the most difficult decision of his career. The reality is that the decision to decommission could be made immediately, regardless of NRC processing and inquiries. Continuing the effort to restart the plant will either mean that NRC will look the other way and allow the unsafe plant to restart at reduced power, ignoring the fact that experts agree that this will likely only exacerbate the rattling steam generators, or spending a great deal of money to replace the steam generators once again, with no guarantee that these will work either.
"The NRC investigation was limited in scope to avoid the most important issue: the regulatory process which allowed the 'super-charged' steam generators to be installed without NRC approval," Lutz said. "Edison engineers bragged about being able to upgrade the reactors without any such approval, and indeed, it was even the 'major premise' of the project. If the NRC is not going to review this, then it raises a good question: when does this review occur or is this just going to be swept under the rug?"
Even if the steam generators were working like they were supposed to, we now know that the plant is in an earthquake zone, a tsunami inundation zone, and would likely fail in any sort of moderate earthquake. Operators admitted last month that vibration sensors on crucial equipment would improperly shut down that equipment in the event of an earthquake.
San Onofre, designed for a 6.0 quake and upgraded to withstand 7.0, is certainly at risk given the recent 7.5 magnitude quake near Mexicali and the recently discovered fault only yards from the reactor site. That new fault experienced a 3.8 quake just last month.
The underlying agenda of SCE, the plant operator, was to "super-charge" the steam generators, essentially upgrading the plant to produce more power without NRC or approval by the public [1]. SCE Engineers admitted in January that they worked to avoid full NRC review of the changes. In an article in Nuclear Engineering International: "the major premise of the steam generator replacement project was that it would be implemented under the 10CFR50.59 rule, that is, without prior approval by the US Nuclear Regulatory Commission (USNRC)" [2, emphasis added].
On April 25, citizen activists submitted a letter to NRC Chairman Gregory Jaczko detailing requests for action prior to any restart of the reactors at San Onofre [3]. These requests will form the basis for some of the questions and comments from the public. Some of the questions from the public should include:
1. Has the NRC investigation determined the root cause of the steam generator failure?
2. Has the NRC also determined why the design error occurred?
1. Was it due to faulty simulations, faulty testing, or no testing or simulation at all, using the "see if it breaks" approach?
2. Is there a fundamental gap in our understanding of physics that limits our ability to predict this failure?
3. Has the analysis from Mitsubishi Heavy Industries been completed, and if so, what was their conclusion, and can we get a copy of their report?
4. The likely root cause is a mis-design by [SCE] and MHI engineers. What corrective action is planned, if any, to rectify the design errors so that excessive tube degradation will not occur?
5. What assurance do we have that the same engineers can do it right this time? If this occurs, will the NRC approve every step of the way?
6. Indeed, since this design was so problematic, what assurance do we have that other systems that are never tested until a disaster occurs will actually perform as intended?
7. SCE has said they intend to plug some tubes and run the reactor at a lower power, but experts agree that this approach will not reduce the rattling of the tubes but instead may increase it. Has there been an analysis to confirm that such operation will reduce tube degradation or is this just a wild guess by SCE engineers?
8. The inquiry by the NRC was limited in scope and did not include any of the regulatory process that also failed to ensure that such poor designs will ever result. Will there be a separate inquiry by the NRC into such regulatory matters? If not, which agency does that type of review?
9. It is clear now that SCE engineers intended to boost the power output from the plant by modifying the steam generators to generate more steam [1 & 2]. Such a capacity upgrade for a nuclear plant would normally require a re-licensing procedure and it would be paid by the shareholders and not by the ratepayers. Since SCE worked around the law to upgrade this plant in capacity without going through the required procedure:
1. will the operators be fined for violating NRC regulations?
2. will the company be required to charge shareholders for this debacle rather than ratepayers, and undo the improper charge to ratepayers that occurred under the guise that this was just a maintenance and not a capacity upgrade?
3. will the relicensing procedure be activated in ex-post facto fashion so that review by the NRC and the public, as required by law, be respected?
10. What is the status of the investigation into the electrical fire that occurred on April 20, 2012?
11. What is the status of the investigation into the worker who fell into the primary coolant pool in January, 2012?
12. What is the status of the investigation into the vibration sensors on the emergency pumps that had to be disabled because they would improperly shut down the pumps in the event of an earthquake?
13. What steps are being taken to address post-Fukushima concerns at nuclear power plants in the United States, including San Onofre? Will the plants be stress-tested to insure that they will be likely to perform as intended when these disasters occur?
14. Seismic studies costing $64 million have been approved for the vicinity of San Onofre. What will be done with these studies when they are completed? Will the plant be simulation tested to see if it will survive any possible earthquake and/or tsunami?

Dry Cask Nuclear Storage: The Endless Simmer......... (a brief history)
At 11:25 AM 6/9/2012 -0700, LS wrote:
>However, Ace, you don't mention that we are still going to have millions of tons of highly irradiated waste to sequester from the biospheree for the next bizillion years even after every single reactor is closed down. Hardened dry cask storage is preferable over pools, and we have to keep on pounding on that. Maybe something better will come along.....

>Nothing is safe. Never will be.
The commentator is correct, I didn't mention it in my earlier remarks (shown below). But still more importantly, I didn't mention that if we don't shut the plants down, we'll have 104 situations with far greater risks than spent fuel pools OR dry casks. And if dry casks are even 0.001% better than pools, well, it doesn't matter because we still will have 104 spent fuel pools too, with fresh and fairly fresh fuel in every one of them, not the "old" and ever-so-slightly less dangerous stuff that's getting put into dry casks. So again we are left with ONE overriding decision point at this time in our lives, and it's NOT "dry casks versus spent fuel pools" or even "on-site storage versus Yucca Mountain". It's that we have to shut off the spigot. America will be utilizing some form of on-site storage for a long, long time. So the true decision point we are all at is this: Will it be dry casks AND spent fuel pools AND operational reactors, or will it be, after five years minimum while the fuel cools and we have a chance to decide, either wet or dry on-site storage? But shouldn't it be HARDENED storage in either case? And don't we have five years to decide? At least five years? But what does "hardened" mean? Retrievable? Earthquake-proof? Tsunami-proof? Fire-proof? Bomb-proof? Stupidity-proof? What about the complications for the local fire departments of putting out a dry cask fire (who have hardly any, or no hazmat suits)? Putting out such a fire is an impossibility, were it ever to start, say, from an airplane crash or a terrorist attack. True, the dry casks in Japan "survived" The Great Eastern Japan Earthquake and Tsunami of 2011. But that's hardly proof they will ALWAYS survive. And WHAT did we see them desperately dropping on the Fukushima reactors? WATER. And what are they afraid they'll lose in Fukushima Spent Fuel Pool #4 if there's another large earthquake in the area? WATER. Can the fuel in dry casks EVER start to burn? Yep. Then what? It will be too late for water. The first dry cask was built in 1986 at Surry NPP in Virginia, four years after Congress passed the Nuclear Waste Policy Act of 1982 decrying that there is, indeed, a serious problem and demanding a permanent geologic solution be found. (30 years later, we aren't any closer.) By February 2001 there were 230 dry storage casks in America. There are now about a thousand dry casks across America, as they furiously build them all over the world, an endless, thankless task. By 2015 every nuclear reactor's spent fuel pool in America will be filled (and overfilled) to capacity. THIS is what's driving the push for dry cask storage, NOT any safety considerations of dry casks versus anything else. According to Scientific American (January, 2009), dry casks hold about 11 tons of spent fuel and cost about a million dollars each to fabricate. In America, we generate about 10 tons PER DAY of spent nuclear fuel. So we're building nearly one dry cask every day in America, and perhaps 5 or 6 per day around the world. Then what? Does it just sit there? No! It rusts. It embrittles. It ages. Weld it properly if you feel like it, but I've heard from TWO whistleblowers in TWO completely different dry cask areas (one worked for SanO where they fabricate their own casks, the other was the late Oscar Shirani) who BOTH said the welding and other aspects of dry cask fabrication was NOT being done properly. They were both terrified of what might happen when these poorly-fabricated parts fail, perhaps when someone tries to unload them for transport, or maybe sooner. Dry cask loading is relatively easy compared to what unloading them might be like in 60, 80, 100 years or more. Sincerely, Ace Hoffman

http://www.nrc.gov/reading-rm/doc-collections/fact-sheets/dry-cask-storage.html
"Dry spent fuel storage in casks is considered to be safe and environmentally sound. Over the last 20 years, there have been no radiation releases which have affected the public, no radioactive contamination, and no known or suspected attempts to sabotage spent fuel casks or ISFSIs. " Like I said, their time will come.... An endlessly growing list (from wikipedia):
"During the 2000s, dry cask storage was used in the United States, Canada, Germany, Switzerland, Belgium, Sweden, the United Kingdom, Japan, and Lithuania. "
Loading a dry cask (from Scientific American):
" In the absence of a long-term solution (such as burying the waste deep inside Yucca Mountain), the nuclear industry has turned to so-called dry cask storage. This involves immersing the radioactive used rods in helium or some other inert gas and slotting them into a steel container that is further encased in a concrete cask.... The encased rods still manage to emit roughly one millirem of radiation per hour and heat the outside of the 100-plus ton concrete casing to as much as 90 degrees Fahrenheit (32 degrees Celsius). "

>>Congrats to the team that provided a compelling argument about the folly of the Nuclear Regulatory Commission's "Waste Confidence Decision." The D.C. Federal Court of Appeals decision effectively torpedos the NRC's risky default policy with respect to multi-decade high-density pool storage of spent reactor fuel. It could pave the way for a more rational, safe and secure policy.

>>FYI , below is a graph developed by the Electric Power Research Institute (EPRI) in June 2010 indicating by the time U.S. reactors are expected to close in 2056, about 133,000 metric tons of spent fuel containing ~27 billion curies of intermediate and long-lived radioactivity will be generated. Note that EPRI projects that 63,000 MT will be packed to the maximum extent into spent fuel pools by that year. Currently about 73 percent of the 67,450 MT of SNF, generated as of the end of 2011 ( according to NEI) sits in pools, which were not intended to hold 4-5 times more than their original designs. Reactors like Vermont Yankee has been holding densely-compacted spent fuel in its elevated pool for more than 30 years. The Millstone I reactor was closed nearly 15 years ago. Yet, 2884 assemblies from the reactor remain in wet storage. Let's not forget about the common pool at the failed Morris, Ill reprocessing plant holding 3,217 assemblies for decades from several closed reac

If we're going to "phase out" nuclear power, shouldn't Phase One be San Onofre, RIGHT NOW?
Dr. Arjun Makhijani (President, IEER) on SFPs vs. DKS:
A Bad Approach to Nuclear Waste (Wash Post Op-Ed, Feb. 13, 2002 by Arjun Makhijani) Dr. Makhijani's bio from the article: "The writer is President of the Institute for Energy and Environmental Research. A study he co-authored in 1992 on nuclear waste was partially funded by the state of Nevada."
--------------
"To eliminate security risks arising from on-site spent-fuel storage, it is essential to remove all the spent fuel from the pools and put it in some form of sub-surface storage, either on site or in a deep repository. In the long term (several decades) no reasonable substitute for a deep geologic repository exists. "But the spent-fuel pools cannot be closed while there existing nuclear power plants are operating. Underwater storage for several years is essential, else the spent fuel will melt and release large amounts of radioactivity. In other words, to end the security vulnerability of spent-fuel pools, existing nuclear power plants must be phased out."
-------------- I've posted a photocopy of Dr. Makhijani's entire op-ed here: www.animatedsoftware.com/environment/no_nukes/2002/IEER-Arjun-Makhijani/IMG_7975-IEER-Arjun-Makhijani.png Short URL: http://goo.gl/h2pZm I have great respect for Dr. Makhijani. But how do you start a "phase out"? You shut a reactor down, then another and another. Ten years on, can we finally start this "phase out" process at San Onofre? I hope he will join our call to keep San Onofre closed forever! Note that current dry cask storage is NOT Dr. Makhijani's concept of "sub-surface on-site storage", what we are actually doing is much cheaper, and leaves the fuel in a much more vulnerable state than his "Hardened On Site Storage (HOSS)" plan. No plan is perfect, but not making more waste reduces the problem for the rest of humanity to only what we have already created.
Kevin Kamps on SFPs vs. DKS:
Here is Kevin Kamps, then of NIRS, and now of Beyond Nuclear (both terrific organizations). Kamps' document is from three months before 9-11. Six pages into his treatise against dry casks he says this: --------------
"Nuclear power must be phased out and replaced with safer, cheaper, cleaner ways to meet our electricity needs: conservation, efficiency, and renewable sources such as wind, solar, and fuel cells."
-------------- Kevin Kamps' full document (in "png" form; shortened URLs):

Page 5: http://goo.gl/fCXvp
Page 6: http://goo.gl/KyyWt
Page 7: http://goo.gl/MOKt4 I have great respect for Kevin Kamps, but I think it's time to "phase out" San Onofre and I thought so then. Right now San Onofre is in a significant state of disrepair. Right now wind, solar, and other renewable energy solutions can provide all the power we need AND much-needed jobs in the state. And right now, The Big One hasn't struck... yet. So what's wrong with now? I hope he will join our call to keep San Onofre closed forever!
