Rich, please review and comment, for distribution to our branch.

In a briefing with Joe Giitter that just ended, we were informed that the situation is now much worse in Japan. The walls of the Unit 4 spent fuel pool have collapsed, and there is no water in there. There were a large number of fuel assemblies in the pool, and the fuel may no longer be intact. The radiation levels are increasing so much that it may prove difficult to work on the other 5 reactors at the site, which could lead to more fuel damage and releases. […]

    that was back in March… we’ll just have to hope that they have fixed the structure somewhat, to withstand further earthquakes…

  • arclight arclight

    bit of an old email, 10 months to see the light of day! hmm!

    “Also, as more of our technical experts get assignments, it may be difficult to complete licensing actions. Giitter and Nelson recognize this, and said that the Japanese response will take priority over the metrics.’ Also, Harold Chernoff is compiling a list of licensing actions (ready to be issued) that may be sensitive (spent fuel pool rerack, reduced containment testing, etc.)”

    reduced containment testing????????????????
    cover up

    the Japanese response will take priority over the metrics?????????
    metrics equals safety?

    Sort of surreal.
    I was sick with a flu bug for the first week of the year, so I missed a lot of enenews.
    During that time it had occurred to me to explain to my girlfriend that if Unit 4 SPF goes, then so does all of my short and long term planning in life.
    And that running off to finish my homestead dream would be an easy decision.
    I wound up explaining all of the latter to her just last night on the phone.
    I told her that if Unit 4 SPF collapses, that will be the pivotal game changer for me. i.e. no long term plans in life (we live near the coast of Oregon).

    Yet what is so disturbing, yet (doh!) predictable, is that this NRC email is from just a few DAYS after the reactors melted down.
    If this is what they had no plans of sharing with the general public, what is the nature and significance of what they intend to hide!!!!??????

    • Whoopie Whoopie

      That’s what I’m seeing from many people. They are planning to GO SOUTH. Who can blame them. As far as THIS news, muther flackers have lied since the beginning and even though the LIES are being caught NOW (thanks to Lucas) WHAT THE HELL NOW?! WE’re in a world of shit, plain and simple. And the LIES wont stop now, it’s just that it’ll be months down the road before we find out what the LIES WERE. sick The Elephant In The Room is ALL NUCLEAR PP RADIATION

    EXACTLY as feared and assumed.

  • kintaman kintaman

    This is dated March 16/2011. So has Unit #4’s spent fuel pool been collapsed and the fuel already melted since way back then or was this email in error? So many contradictions and unclear stories that lead one to not know what the heck is going on.

    • jimbojamesiv

      If you take a look at the front page ENEnews, another story contains an email dated to March, which states that the spent fuel pools at Unit 4 were already on fire, and that’s March, which is news to me.

      It’s the most recent story about 5 persons being exposed to lethal doses.

  • jec jec

    5 + 1 = 6 REACTORS! Fukusima 1 only has four (4). Anyone else see the math problem?

    • Wotcha Wotcha

      Hi Jec
      Daiichi does have 6 reactors: 1 to 4 are fairly close together, but 5 & 6 are on their own, a little way from the others. When the big EQ came in March, R4 had just been de-fuelled but I think 5 & 6 were in cold shutdown. Little is ever mentioned about 5 & 6 though.

      • Heart of the Rose Heart of the Rose

        Here is the last info ..I have about 5 and 6.
        I’d offered my analysis..when first posted…months ago.
        Globs of grey matter is corium…might as well be human brain matter…
        Tell me… on other planets there are inhabitants rubbing sticks together for the purpose of blowing themselves up…..

    • Cataclysmic Cataclysmic

      Actually, I recall the locals talking about 6 reactors right from the beginning.. remember our poor French man showing us the news? ..or lack of it? He said their were 6 reactors.. and I recall contaminated water in the basements, of 5 and maybe 6.. that was suspected of coming up from underneath.. fairly early on.. now, what I do not understand.. is 5 and 6 Daini? or are there even more there?

  • sworldpeas

    The e-mail is dated March 16th…
    This video of unit#4 SFP boiling is dated May 7th.

    Seems we are rehashing old speculative e-mails before we understood the reality of the situation. It’s called FEARMONGERING and I hate that. 🙁

    • Kevin Kevin

      Something tells me the NRC is not big on speculation of this sort.

      Anyone familiar with the layout of the reactor containments, as I was not until the incident, has feared this from the very beginning.

      That the official narratuve has deflected concern away from all the real issues is enough evidence for me to accept this information as far more valid than anything I have seen or read that has been reported by repeaters who acquire information from sources far less likely to be accurate then the NRC on these matters.

      This is a “bomb” of an email.

      • sworldpeas

        Well someone should tell Arnie apparently he is completely uninformed about unit 4 collapsing. I’m surprised that they are able to walk around on top of the building and dismantle it like in the current videos we have seen. You’d think the area would be to dangerous to be around for hundreds of thousands of years NOT 8-9 months later.

      • Kevin, according to an entire raft of the technical assessment task force’s gathering of data from sources in Japan and via their own analysis from offshore monitoring and satellite imagery, the NRC estimates of releases counted 50% of volatiles and soluble fuel/product isotopes from 1 reactor – Daiichi unit-1 – and 100% from the overloaded #4 SFP. They avoided unit-3’s contributions to worldwide distribution for as long as they could, and don’t seem to have considered unit-2 at all. The amount of limiting isotopes stored in the #4 SFP greatly outdoes all of the fallout produced by all nuclear weapons ever exploded in atmosphere or water since the beginning of the technology, so I guess they figured that was already “worst-case scenario” and everything added to it was just overkill.

        • Joy can i quote you on this analysis?

          • Sure, majia. I’ve got the NRC docs pertinent around here somewhere (whole big file full, but dumbly not searchable). They include their assessment of 50% unit-1 core inventory and 100% #4 SFP inventory, plus a different document on just what their calculations for #4 SFP’s inventory was. There were news stories months ago, have those saved somewhere too… if anybody gives you a load of sh*t, I’ll go wade through to find ’em.

            • Joy Which NRC documents?

              I have their latest report but there are no data about releases.

              I think I have a report from this summer–June or July–but I had trouble finding it today. I probably saved it on a flash drive rather than my hard drive.

              I am trying to assemble evidence for my argument about censorship to be given at a conference in Feb.

              I hope you are going to attend that?



    • The source is Lucas Hixson’s website. Where he has been laboriously sifting through literally thousands of NRC internal documents released to him in response to an FOIA request last summer. To link and cite these documents as part of his site’s section on FOIA releases is perfectly legitimate, makes the documents publicly available for all public purposes of research and analysis.

      Yes, there is quite a lot of speculation in those early in-house emails as various NRC task forces worked to gather information and analyze the situation. Some of what was gathered turned out to be correct, some was incorrect. NRC did not trust anything coming from TEPCO or the Japanese government, nor did it trust IAEA (for experience and good reason).

      If reading internal documents from NRC in the early weeks/months of the disaster is distressing to you, perhaps reading enenews citations of source would allow you to skip those documents. I for one find them fascinating for a number of reasons, as are the many more ‘secret’ documents later released to U.S. Congressmembers (Ed Markey, i.e.) in response to their more high-level demands for data.

      • sworldpeas

        Hi Joy
        The problem is that people think it HAPPENED and without a disclaimer it leads people to WILD speculations. According to the NRC they think unit 4 has collapsed… so lets be perfectly clear about it, did it collapse like the NRC says? or was this speculation in March on their part? What purpose is there to rehash speculation when we already know the facts? At this point in the disaster we should be dealing with FACTS not a false speculation from 9 months ago. The NRC thought something that was NOT true END OF STORY put it to rest already!!! and MOVE ON!

        • Kevin Kevin

          Oh, we know the facts do we?

          I was not aware of that.

          By all means move along.

          • sworldpeas

            FACT: unit 4 sfp did not collapse in March. If you want to argue it did then please provide evidence of it’s collapse. This e-mail is not evidence.

            • Kevin Kevin

              It is interesting that you state the “Facts” yet ask me to provide the information.

              It would seem the onus is on you, as I have said, I dont what the case is.

            • Kevin Kevin

              I have listened to this video.

              It is very important and relevant.

              You should do the same.

              Note the language used.


              I would appreciate comments?

              • sworldpeas

                At 2:20 he says that it is unlikely that the pool ever went completely dry based on the video and water samples.
                I don’t know what else to say other then this NRC e-mail was SPECULATION in March that proved to be wrong and YOU just confirmed it in the video you posted. So Kevin do you think the NRC e-mail was right or wrong in March? Did unit 4 collapse? or was it speculation? I posted a video of the boiling SFP from May you provided a video saying that unit 4 was intact yet you want to believe an e-mail from march? I’m at a loss here…

                • Kevin Kevin

                  I did not say I wanted to believe anything.

                  I am interested in finding out, as I said below, what prompted staff to make the claims and, in turn, on what basis did the NRC senior staff dismiss the claims.

                  It seems to me that, based on the video I provided they are saying the notion is “unlikely” which is not a definitive, and the claim is staked entirely on the video of the SFP 4 fuel pool.

                  So there is no definitive answer either way, which is my point, and there is enough evidence to suggest further invesztigation

                • We know lies abound, how does one know even what a video is of? They are trying to save their industry, their careers, their pension, their families. THEY will do anything, any lie can be justified.

              • Dr. Anne Lee Tomlinson Maziar anne

                The person to the right keeps looking down and over his right shoulder at ? It reminds me of George Tenet before the US invasion of Iraq when Colin Powell was reading and presenting the “evidence” of weapons of mass destruction in Iraq before the UN. It certainly looked like Mr. Tenet knew the presentation was just a bunch of lies. He kept his head down and then now and then looked up to see the reaction which still keeping his head down.

                In this case perhaps the person to the right is looking down and reading something. Still?

        • Well, the lede on this headline is “NRC March Email,” so I don’t see why anybody would then assume it’s anything but an internal NRC email from March. Which is what it is – internal circulation of analysis gathered from TATF members, DOE scientists and academic contacts. Correct or incorrect, it remains the product of those early analyses and proper circulation to other Op-Center attached task forces dealing moment-to-moment with the disaster in Japan.

          But I’ve been doing an alternate analysis of the FOIA releases (full list of links at bottom), for historical purposes. Thus I’m interested in all of them, and have no preconceived notions about whether any of the data is actually accurate. Just an examination of our own U.S. nuclear “regulatory” (hahaha) agency and the many ways that it DOES NOT serve the people of this country. Which is something I believe to be important, because once it is understood that nobody’s got a real handle on any of this shit, the more pressing becomes the need for the entire technology to be shelved with others of humanity’s extremely bad ideas.

          • Kevin Kevin

            Good for you for taking on such a task.

            One of the things I learned from Arnie, and it seems it is your experience as well, is that NRC essentially stands for Notorius for Realistic Coverups.

            So the as the situation stands.

            Staff found reason to believe that SFP 4 had integral damage and water escaped leaving the fuel bare.

            Shortly there after, as the video I provided states. higher ups acknowledged the work of the staff and communicated that it was “unlikely.”

            Nothing was said about what caused the original claims or what the higher ups base their negating of staff claims upon.

            So to my thinking we need to know what prompted such claims to begin with and why senior NRC types refused the information and communicated the “liklihood” of it being false.

            The definition of cover up is knowing one thing but communicating another.

            • We now know – or, we have now been informed, who knows what’s really real – that reactors 1, 2 and 3 have melted through. In March, corium has been on the loose ever since. Notice the NRC doesn’t say anything (or count in its release figures in this email chain) those melt-throughs, the spectacular explosion of unit-3 [MOX!], or the raging fire in #3 SFP that burned twice, for days, over a week and a half.

              Instead, what we got was this “100% #4 SFP” distraction. Which TEPCO easily countered with pictures, video, etc. of #4 SFP showing it intact and not dry or on fire. If that evidence is believable, which is anybody’s guess. Pure sleight-of-mind, with the U.S. NRC playing Who’s On First gag. Units 2 & 3 explode (one so bad it flung MOX fuel rods for miles), so “Look! Over There!” (#4 SFP). Then #4 blows out, so it’s back to “Look! Over There!” (#1 ‘might’ be melting!).

              Honestly, it’s hard to keep the Klowns straight without a program… Which is precisely the point, n’est ce pas?

              • Kevin Kevin

                This is precisely it.

                There is unending reams of evidence that proves the “whos on first” disinfo campaign has been and continues to be in full swing.

                The staff however, made a clear observation and wished to communicate it internally. The implicatoins of which are so serious the information became public and higher ups used the spin campaign.

                Not very reassuring.

                • Cataclysmic Cataclysmic

                  re unit 3 from FOIA.. “It’s steam all right & U3 SFP boil off is the best guess. The pools should have lasted min. 8 days (by the most conservative calcs I saw – 10 days is a better estimate) after the event before they got to the magic 50% covering of the fuel assemblies which gives you the Zirc oxidation & H2 liberation. I understand the guess is the pool lasted 72 hours – you can infer what happened.”

                  The core is melted & the primary is full of sea water, so it could be coming off the hot primary containment?

                  But everyone is betting on SFP ………”


                  • Kevin Kevin

                    With respect to reactor three. The secondary containment (buidlings we all see now destroyed) had steel reinforced pre-stressed concrete walls that range from 4 -8 feet thick. They were blown away like it was popsicle stand. The internal walls would have been less robust. Hence the fuel pool was undoubtedly affected in my opinion. IF 4 was affected withuot anywhere near the blast and no operating core, three certainly was.

                • Well, if I had to bet on any of the info/disinfo, I’d strongly suspect that indeed it was the #4 SFP that collapsed and burned, and that the #3 SFP (the distraction) was so destroyed by the core explosion that there wasn’t anything left to worry about. So long as individual assemblies are scattered and enough structural junk is on top, just another roped-off “high radiation” area the workers get to stay away from until it’s done doing its thing. Unit-4 didn’t have a reactor in operation, managed to destroy itself almost as thoroughly as unit-3, but nobody got to see that show live. There one day, utterly demolished the next, almost like an afterthought.

                  But then again, I have a high degree of skepticism about everything we’ve been told, by all ‘authorities’ who have told us lies. You’d think from the NRC internals that it was like pulling Russian teeth to get info, and that’s simply not the relationship the U.S. and Japanese nuclear industries/authorities have had since the very beginning. They’re thicker than thieves. Always have been.

                  • Cataclysmic Cataclysmic

                    notice they did refer to pools not pool..
                    and Joy, I for one, would place no money on 4 actually not being in did it destroy itself if not in operation, and no fuel? I seem to remember a whole lot of weird info coming out initially, and lots of speculation.. seemed like the temperature reports or something from TEPCO did not support this.

                    • Dr. Anne Lee Tomlinson Maziar anne

                      They’ve already hypothesized that it exploded from pipes connecting it to reactor #3.

                    • That ‘explanation’ never held any water with me [heh, pun intended], anne. Too late and sans any sort of data on how, exactly, the gas got into unit-4 from unit-3 when neither (actually NONE) of the reactors were vented to the stacks at any point in the drama.

                      Sure, we were told the containment/torus vents were crap, but it was clear from Day-1 that the amount of crappiness precluded proper venting to stacks – it ALL went into the secondary containment atmosphere instead, at ALL the affected plants. At any rate, I’ve discounted the “shared vent” hooey all along. The plants would NOT be sharing pathways even if they did share the actual stack. Thought they could get away with that because they did design-in shared control rooms. Shared control rooms do NOT mean shared reactors, containments, toruses, vents or spent fuel pools. Just means they saved a little bit of money during construction on electrical wiring and pneumatic instrumentation conduits.

                    • Bobby1

                      It was initially reported that reactors #2 and #4 exploded within a few minutes of each other. Months later, Tepco took it back and said #2 didn’t explode. Huh?

                      Well, #2 and #4 are on either side of #3, and I have suggested that the #3 corium (the portion that didn’t blow up into the sky) was already underground, and hydrogen and other gases found they way through underground conduits, pipes and fissures, causing the explosions. Of course, Tepco would never admit to the corium being underground, especially at this early stage.

                    • Joy, et al, I have always wondered about this article, which argues 4 was in operation clandestinely. How does its science look? Good, bad, indifferent? Thanks


                    • Hi, risabee. This speculation looks to be specific to the ‘mystery’ of why unit-4 exploded if its reactor was empty. That is indeed a puzzle if you assume that it takes a melting REACTOR to cause big hydrogen explosions.

                      Technically, however, it doesn’t take a melting reactor core in an actual REACTOR vessel. Anywhere the assemblies are uncovered, the zircalloy oxidation will occur and produce hydrogen just as explosive as what wasn’t supposed to be coming out of any of the reactor vessels. And the fuel will melt just fine in a dry SFP too, no need for a reactor vessel.

                      The ENTIRE unit-4 reactor core was in the SFP. Along with several reactor’s worth of ‘spent’ (but not really) core assemblies that had been there longer.

              • Heart of the Rose Heart of the Rose

                The debate about reactor 4…does not distract us from ..accessing the situ in it’s entirety..or by aspect..

            @Kevin & @JoyB! Thanks for your clear, reasoned discussion. This was very helpful and definitely what is needed.

        • BreadAndButter BreadAndButter

          I agree.

      • Kevin Kevin

        I am not sure if you are responding to me in both of these emails, but I dont find it distressing. If folks who jumped on my post would reread it, the point was that NRC internal emails are a more valid source of information in my view than media reporting.

        That said, I dont know what is going on and if the email is accurate. Either way it is still a bomb. The language leaves no wiggle room, and it asking for approval to be broadly disseminated within the NRC an organization not broadly known for acute and unrefutable information sharing in the accurate sense.

        The point is, as I think Joy alludes to. SFP4 could be another exercise in diversion and the truth could be that much of the fuel there is also in trouble or gone. We have seen video showin the pool in tact, however was that video actually SFP 4? Or was it 5 or 6 or from some other one? Who knows for sure?

        I agree with the overkill analysis it seemed early on they knew this was really bad, and ever since it has just been damage control. In that scenario bold face lies are common.

        • Yes, it is difficult to discern the lies from the sleight-of-mind distractions. Which began immediately and have continued unabated to this day from every nuke-related concern on the planet.

          Every time they wish to divert from melted reactors they change the subject to damaged fuel pools. Then when the damaged fuel pools start looking more dangerous, they divert back to melted reactors. Like this week’s casual throw-aways about Daiini, designed to sow confusions and distract our attention from Daiichi. They are tireless in the quest. If the truth cannot be hidden completely from view, it can work just as well to simply inundate with minutia, cry “Look! Over There!!!” while the walls you WERE looking at come tumbling down…

          • Dr. Anne Lee Tomlinson Maziar anne

            I don’t think that Fuku Daini is a throw away or diversion. I think that the vessel damage in one of the reactors ( which one?0 or all four is extremely serious. I am thinking that they are just now admitting it publically what they have known since March.

            I am compiling info. on Tokai NPP and earthquakes here. I think everything is diverting attention from Tokai where there are potentially much greater scandals to be revealed.

            • Would sure love to see what you’re able to gather, anne. There’s so many plants all over Japan’s coasts that we can never be sure that any of the many that remain off-line aren’t in bad shape all on their own. Please keep us posted!

        • Cataclysmic Cataclysmic

          Well, for my 2cents, for what it is worth… after the initial accident.. the professionals had yet to understand the need to cover up and down play anything.. which means(to me), that this is the experts honest opinion of what happened based on the data and information they had access to.. their educated guess with more data than the rest of us are likely to ever see… what I remember, is that there is really no way to hide a melt down or ? because the isotopes give it all away. (at least to the scientists)

          • Alas, while all nuclear nations’ monitoring systems plus IAEA and the weapons testing monitors all know that what’s come out of Japan is worse than Chernobyl, they are ALL still insisting it’s not half as bad. That’s pure, unadulterated BS, easily seen for BS when you recall that half of one reactor at Chernobyl melted and spewed, compared to God only knows how many 100% melt-spews from Japan. None can be trusted.

            • Bobby1

              Well, it’s true that it is BS, but the physics for the atmospheric models was wrong, it assumed that radioactive particles would travel to the same altitude as nonradioactive ones, when in truth they traveled higher, due to the release of heat. This led to underestimates of the amount of radiation release from Fuku.

              Of course this basic fact of physics should have been known by the ’40s. Suppressed?

              • Basic stuff. Clearly, the models were wrong. Hence re-calculations of release that are still off by a few factors of ten. But the original atmospheric modeling for plume paths – IF I recall correctly (and that can definitely be iffy after all these months) – were done by your basic weather-folks in an attempt to help raise the warning. Because when the disaster happened, the nuclear industry/authorities in THIS country (at least) were still swearing on stacks of Bibles that releases of radioactive contamination from nuclear plants does not move in plumes.

                A legal technicality they invented to ward off civil liability for Met-Ed/GPU after Three Mile Island, that then had to be pretended to be valid despite the fact that it has always been known to be bull.

                • Bobby1

                  They knew the releases moved in plumes no later than the ’50s, there are published papers about it.

                  The fiction that contaminants move in an expanding sphere, modeled by inverse cube laws, regardless of wind, is ridiculous and always was ridiculous. The atmosphere is a river of air.

                  • True. But that’s how the authoritarians got the Judge (named Rambo, btw) to rule, based on both Kemeny and Rogovin HPTF “findings” that there were no plumes. As I said, civil liability. Neither judge nor jury knew any better, and were not allowed to hear otherwise.

                    Thousands of people. Really. A sadder case of official coverup and malfeasance can’t be found anywhere. Innocent citizens deliberately (but regrettably) sacrificed to the nuclear godling. Having seen that up close and uncomfortable, 9-11 didn’t shock me at all… Cost-benefit. You have to think in their terms, and that’s horrifying enough that most people will turn away instead. Which is just what they counted upon.

      Rehash of old emails- but they are not in the public eye. So when these emails come up, it verifies what we “see” on the ground via webcam, comments/email, and “breaking news”. At least when shills comeback with “all is fine, just smile” we can point to an outside source as a collaboration.Not dreaming this stuff up dudes!

      use of the word ‘fearmongering’ should result in an auto ban (7 days?).

      (ironically, were this in place, i’d now be banned)

      why is tepco still in charge? we wouldn’t need to speculate about the state of sfp4 if they were releasing all the data.

      satellite data would also serve to confirm within a small margin of error exactly how hot sfp4 got.

    So where does this leave us? Are we approaching “On the Beach?” Is there anyone out there that can give us the straight skinny? Who can we believe?

    • Well, a nice gentle system-restoring cure for cancers and heart-hardening and autoimmune/immune dysfunctions would be really nice to hear about right now. Entirely unlikely so long as there is profit in disease and tortures (not cures) for disease. But until and unless humans as a species no longer live long enough to reproduce, we will not go extinct. There could be a lot fewer of us in the future, though.

      • Check in with local holistic healers or Naturopaths. The answers are there.

        • Hear you, AGR. I am an herbalist. But even I am running short on effectives as the climate changes and the shit rains down. Last of the Elderberry done for the year, they’re putting in a new highway and the elders we’ve saved aren’t re-established enough to fruit yet.

            The herbs and seaweed and chorella and spirulina and Himalayan salt, etc., are the best we have. They are less radiated than any animal products. However, they are heavily radiated, no doubt about it.

            • Oh yeah. Salt. Guess I’ll have to start careful label-reading on my sea salt… though soon all the seas will be so polluted by something or other we’ll all have to go back to mined salt – with added iodine, since the kelp is contaminated too. Sigh.

        ‘A nice gentle cure for heart-hardening etc,’ well put. Fewer of us in future, and lately I keep thinking that could happen bcs we’d all have much shorter lifespans.

    “The lying began by the Ides of March. TEPCO, the NRC and the government of Japan had actual knowledge of these events and the melt-throu­ghs at Units 1, 2, & 3. Unit 1 had the most problems since the fuel rods were exposed longer by systems failures due to antiquated design, of which they had been repeatedly forewarned by whistleblo­wers. Naturally, telling the truth in advance had been dealt with severely in retaliatio­n against those brave souls.
    The tort system in Japan needs beefing up since government regulation has failed. Caps and immunities lead to this very result every time as regulation is captured or offshored into internatio­nal alphabet soup “agencies” whose function is to control health informatio­n and to form “scientifi­c consensus” statements that may be used offensivel­y against critics.

    Now they have to restart to crippled reactors to obtain bank loans to save the investors. The tail again wags the dog. Greed is incompatib­le with public safety.

    Allow me to interpret the above:

    Joe Giitter is so concerned about the impact of the Fukushima ELE upon the NRC’s rubber-stamping of new licenses that he will try to be in his office for TWO WHOLE HOURS to answer any licensee’s questions, and will be working SWING SHIFT at the Operations Center as well – Let’s put our hands together for Joe!

    Allen Howe is putting together a very timely Powerpoint slide show for the Commission about reactor safety, tentatively scheduled for Fall 2013 – Let’s put our hands together for Allen!

    Nelson (Admiral? Ricky? David? Ozzie? Harriet? Bart Simpson’s friend?) has been assigned to lead a communications team for NRR. – Let’s put our hands together for Nelson!

    If you know anything about reactors and will work for free, please volunteer for duty at the NRC Operations Center. Congress is currently considering a bill to authorize temporary funding for a box of doughnuts for the volunteers at the Operation Center, but they expect stiff Republican opposition to yet another “entitlement” program.

    Once again, we apologize for any delay in the issuance of new reactor licenses due to the totally unforseeable Fukushima ELE.

    Fire burns ceiling of Tokai village nuclear reactor building

    “A fire partially burned the ceiling of a building housing a nuclear reactor at the village of Tokai, Ibaraki Prefecture, on Tuesday, the prefectural government and the reactor’s operator said.

    “The fire broke out at around 9:30 a.m. and was extinguished two hours later, they said, adding the blaze at the research reactor facility did not result in any leakage of radiation into the environment. No one was injured.

    “The ceiling under the steel plate roof of the building was set alight by sparks during welding work on the roof, Japan Atomic Energy Agency said.

    “A 110-square-meter area of glass-fiber acoustic absorbent covering the ceiling was burnt, it said.

    “The reactor core is located in the underground section of the 22-meter-high building. The reactor has been undergoing a periodic check since September.

    “There was no change in the airborne radiation levels inside and outside the building, it said.

    “Part of the roof was corroded and “there is a high possibility that the sparks fell through that part onto the ceiling,” an agency official said.

    “The agency started operating the reactor in 1975 for research on nuclear fuel safety. It suspended operation in February, before the March 11 earthquake and tsunami that crippled the Fukushima Daiichi nuclear plant in Fukushima Prefecture, north of Ibaraki.

    Criticality accident at Tokai nuclear fuel plant (Japan)

    “On September 30, 1999, a criticality accident occured at the Tokai nuclear fuel plant, Tokai-mura, Ibaraki Prefecture, Japan. The plant, operated by JCO Co. Ltd., a 100% subsidiary of Sumitomo Metal Mining Co. Ltd. , converts enriched uranium hexafluoride (UF6) to uranium dioxide (UO2) for use in nuclear fuel. Criticality accidents involve a self-sustaining chain reaction caused from handling of too large amounts of enriched uranium. The chain reaction continued for around 20 hours, before it could be stopped.

    “The uranium processed was enriched to 18.8% of uranium-235, rather than the 3-5% used for commercial light water reactor fuel. Material of this high enrichment grade was being produced for the experimental Joyo Fast Breeder reactor.
    The plant has an annual production capacity of 715 tonnes of uranium for light water reactors, and 3 tonnes of uranium for fast breeder reactors. …”

    Honshu Mw=9 Earthquake 11 March 2011
    Damage in Tokyo

    “For several decades Japanese scientists have been anticipating a large earthquake to shake Tokyo from the south – as a repeat of the Mw=8.4 Tokai earthquake (which occurred previously in 1498, 1605, 1707 and 1854). The 11 March earthquake released 8 times more energy than this anticipated earthquake and occurred on the Japan Trench to the north and east of Tokyo. The earthquake did relatively minor damage in Tokyo, testimony to its resilience. It is difficult to ignore the fact that significant stress changes have now occurred near the Tokai epicenter, that may have brought this incrementally closer to failure.

    “As part of a NOVA team 13-17 March I visited scientists in ERI to learn about the scientific response to the earthquake. Access to the epicentral region proved difficult due to flight restrictions and power, fuel and food shortages….

    “In 2004 Prof. Kiyoo Mogi reminded planning authorities of the dangers to epicentral nuclear power plants.

    “’Although the possibility of the occurrence of a great shallow earthquake in the Tokai region was pointed out by the Coordinating Committee for Earthquake Prediction in 1970, soon after, plans for construction of a nuclear power plant started in this region. Since 1976, Hamaoka nuclear power plants (Units 1-4) have been operating near the center of the expected focal region of the great Tokai earthquake, and Unit 5 is under construction. This is quite a dangerous situation.. ”

    • Dr. Anne Lee Tomlinson Maziar anne

      How has this affected the predicted Tokai earthquake?

      “Aftershocks from the 11/3/11 Tohuko earthquake migrated south, some within 50 km of downtown Tokyo, and to the south near the forecast Mw=8.4 Tokai earthquake region. The possibility that the three Nankai segments SE of Tokyo could fail in a single earthquake has hitherto been considered unlikely. Should a single earthquake prevail its magnitude could match the recent mega-quake….”

    Nuclear Power Plants and Earthquakes

    “…Japanese nuclear plants such as Hamaoka near Tokai are in regions where earthquakes of up to magnitude 8.5 may be expected. In fact the Tokai region has been racked by very major earthquakes about every 150 years, and it is 155 years since the last big one. Chubu’s Hamaoka reactors were designed to withstand such anticipated Tokai earthquake and had design basis S1 of 450 Gal and S2 of 600 Gal. Units 3 & 4 were originally designed for 600 Gal, but the Ss standard established in September 2007 required 800 Gal. Since then units 3-5 have been upgraded to the new Ss standard of 1000 Gal. In August 2009 a magnitude 6.5 earthquake nearby automatically shut down Hamaoka 4 & 5, with ground motion of 426 Gal being recorded at unit 5. Some ancillary equipment was damaged and reactors 3 and 4 were restarted after checking. Restart of unit 5 was repeatedly deferred as the company analysed why such high seismic acceleration was recorded on it, coupled with some planned maintenance being undertaken during the shutdown. It restarted in January 2011.

    “Hamaoka units 1 & 2 had been shut down since 2001 and 2004 respectively, pending seismic upgrading – they were originally designed to withstand only 450 Gal. In December 2008 the company decided to write them off and build a new reactor to replace them. Modifying the two 1970s units to new seismic standards would have cost about US$ 3.3 billion and been uneconomic, so Chubu opted for a US$ 1.7 billion write-down instead.

    “Early in 2010 Japan’s METI confirmed that the seismic safety of the Monju fast reactor was adequate under new standards requiring Ss of 760 Gal PGA. Assessments were carried out in conjunction with Kansai’s Mihama plant and JAPC’s Tsuruga plant, both nearby.

    • Dr. Anne Lee Tomlinson Maziar anne

      “South Korea’s new APR-1400 reactor is designed to withstand 300 Gal seismic acceleration. The older OPR is designed for 200 Gal but is being upgraded to at least 300 Gal so as to be offered to Turkey and Jordan.

      “In the USA the Diablo Canyon plant is designed for a 735 Gal peak ground acceleration and the San Onofre plant is designed for a 657 Gal peak ground acceleration. On the east coast, North Anna shut down in August 2011 during a 5.8 magnitude earthquake with epicenter 20 km away when the ground acceleration reached 255 Gal, against design basis of 176 Gal. No functional damage occurred. Subsequent inspections of the plant were based on NRC’s Regulatory Guide: Restart Of A Nuclear Power Plant Shut Down By A Seismic Event, adopted in March 1997. It was the first US nuclear plant ever to be shut down by an earthquake. The NRC approved restarting it in November, having ‘completed its safety evaluation review.’…”

    TABLE-Japan nuclear plant ops (Tokai Daini under repair until Aug)
    Wed Oct 12, 2011 9:20am GMT
    Oct 12 (Reuters) – Japan Atomic Power said on Wednesday that repairing its
    quake-hit Tokai Daini nuclear reactor will take until August next year, about nine
    months longer than originally planned, as the facility’s turbines need extra work.
    The 1,100-megawatt reactor in Tokaimura, 110 km northeast of Tokyo, has come under
    the spotlight this week as the town’s mayor has called on the government to
    decommission it. The 33-year old reactor has an allowed life of 40 years.

    Currently, only 10 reactors in Japan with a capacity of 8,684 MW are generating
    electricity, leaving just 17.7 percent of the nation’s total nuclear power capacity in
    use. Public fears about nuclear safety after the Fukushima nuclear crisis have
    prevented local governments from giving utilities the go-ahead to restart reactors
    taken down for routine maintenance.
    Japan, the world’s third-biggest nuclear power user, has 54 reactors for
    commercial use, with a total generating capacity of 48,960 MW.
    In the table below, capacities are shown in megawatts. “P” represents a planned
    regular inspection shutdown and “U” an unplanned shutdown.

    TEPCO Releases Document Claiming Unit 3 Blew Up Unit 4
    August 27th, 2011

    “TEPCO released a schematic claiming it explains that unit 3 caused the explosion in unit 4. It shows high radiation readings in the exhaust treatment equipment of unit 4 and states that there was a backflow of gas into unit 4.

    “If this is the case and unit 3 had so much hydrogen generating ability that it destroyed two reactors in massive explosions what does that say about MOX fuel safety?”

  • Dr. Anne Lee Tomlinson Maziar anne


    “In other relatively recent news, Tepco in November confirmed that the explosion at the Unit 4 reactor, which had no fuel in its core, was caused by a backflow of hydrogen gas from shared pipes with the Unit 3 reactor. This has profound implications for multi-unit reactor sites with shared components….”

      Design of Fukushima venting pipes prompted explosion
      December 28, 2011
      By TATSUYUKI KOBORI / Staff Writer

      “The structure of venting pipes may have led to the hydrogen explosions that rocked the Fukushima No. 1 nuclear power plant during the early phases of the accident, a nuclear expert said.

      “Water vapor was vented from the containment vessels of the No. 1, No. 2 and No. 3 reactors to reduce the risk of damage caused by high internal pressure withing the vessels.

      “But the venting pipes were structured so that hydrogen in the vented gas could flow into the reactor buildings.
      “‘Under that structure, venting could turn into a self-bomb,’ an expert said.

      “The Nuclear and Industrial Safety Agency (NISA) said it cannot deny the argument that the structure of the venting pipes may have caused the hydrogen explosions at the No. 1, No. 3 and No. 4 reactor buildings. NISA is now discussing safety measures regarding those pipes.

      “Tokyo Electric Power Co., the operator of the Fukushima No. 1 plant, has so far maintained that the explosion at the No. 3 reactor building was caused by hydrogen leaking from the reactor to the reactor building interior through openings on the lid of the containment vessel and elsewhere.

      “When TEPCO on Dec. 22 inspected the pipes of the “emergency gas treatment system,” which extends from the venting pipes of the No. 3 reactor into the reactor building, it found traces of gas inflow.

      “At the No. 3 reactor, gas in the reactor containment vessel was vented on multiple occasions starting on March 13. Hydrogen likely flowed into emergency gas treatment system pipes on those occasions.

      • Dr. Anne Lee Tomlinson Maziar anne

        “Those pipes are equipped with valves and a back flow prevention apparatus. But the valves are designed to open automatically when power supply is lost during an accident. It was also learned that the back flow prevention apparatus was not completely airtight, raising the possibility that hydrogen leaked through and entered the reactor building interior.
        “The venting pipes at the No. 3 reactor are also connected to the No. 4 reactor building. But there is no back flow prevention apparatus on the No. 4 reactor side.
        “TEPCO said in an investigation report in August that the explosion in the No. 4 reactor building was caused by the inflow of hydrogen gas vented from the No. 3 reactor.
        “The venting and emergency gas treatment system pipes are structured in a similar manner at: the No. 1 reactor, where another hydrogen explosion occurred; TEPCO’s other nuclear reactors; and the boiling water reactors operated by Tohoku Electric Power Co., Chubu Electric Power Co., Hokuriku Electric Power Co., Chugoku Electric Power Co., and Japan Atomic Power Co.
        “’The interconnection of pipes has enhanced the danger,’ said Tadashi Narabayashi, a professor of nuclear reactor engineering at Hokkaido University.
        “NISA on Dec. 27 said subjects for discussions on safety measures include the independence of the venting pipes and installing hydrogen back flow prevention valves along the emergency gas treatment system.
        “The nuclear watchdog also said an analysis showed that large amounts of hydrogen leaked through openings in the containment vessel.”

        • Wow. That’s gotta go down in engineering history as the stupidest f&#$’ing design any educated human ever came up with! And no (please, God!) I do not think NRC would sign off on such an obvious idiocy in this country.

          …but I guess we’d probably ask ’em directly just to make sure, now that they’re doing “power upgrades” for MOX burning at the rustbuckets and planning to build more reactors in the same too-close (to populations) reservations. I’ve no real faith our nukes are any smarter than anybody else’s nukes.

      “4H – Stack shared by the Unit 3 and Unit 4 reactor building exhaust system. Air from the reactor buildings is discharged from this stack during normal operations. During accident conditions, a system within the reactor building routes air through a charcoal filter system before sending it to the stack for discharge. The primary containment is vented through the reactor building charcoal filter system before flowing through the lines to the stack….”

    • Dr. Anne Lee Tomlinson Maziar anne


      “…At approximately 6:00 on 15 March, an explosion occurred in the Unit 4 reactor building. Since the spent fuel in the Unit 4 spent fuel pool appears to have been covered with water precluding the generation of hydrogen, the source of flammable gas is unclear. A potential source is hydrogen in the Unit 4 reactor building backflowing from the Unit 3 standby gas system lines through the vent lines of Unit 4. Units 3 and 4 share a common header that vents to the exhaust stack.[p. 33] ….”

    So who is lying, or are both, Tepco and the NRC?

    Is the FOI email a fake? Has SPF 4 burned up already or not? Are they hiding it hasn’t yet, or that it already did?

    There are now ten reactors in question, and who knows how many spent fuel pools.
