Doubt over meltdown dispelled

Now, a little over two months later, new information on the state of Fukushima Daiichi’s three overheated reactors is making the m-word impossible to avoid. Fuel inside the cores, it is now understood, melted far more quickly and extensively than was initially believed – disintegrating just a few hours after the tsunami knocked out the plants electricity and cooling systems.

JNI Team analysis (from previous ROV and Diaries)

Story Here:,Japanese Times

High radiation readings taken in the No. 1 reactor building the night of March 11 suggest it was the quake rather than the loss of cooling that critically damaged the Fukushima No. 1 power plant, a utility source said Saturday.

The belated disclosure could trigger a review of quake-preparedness at nuclear facilities across the country. Many have been focusing on increasing defenses against tsunami, which knocked out the plant's poorly placed emergency power generators.


Based on the dosimeter readings [when workers entered the building in the middle of the night], the radiation level was about 300 millisieverts per hour, the source said, suggesting that a large amount of radioactive material had already been released from the core.

The source of the steam was believed to be the No. 1 reactor's overheated pressure vessel.

But for that scenario to hold, the pressure in the reactor would have to have reached enormous levels --- damaging the piping and other connected facilities. It should have taken much more time to fill the entire building with steam.

A source at Tepco admitted it was possible that key facilities were compromised before the tsunami.

It sound like TEPCO is inching toward a disclosure that unit 1 did not scram properly after the earthquake.

I remember reading some earlier ( conjecture too that it could have been quake damaged. I can't recall now who said it. But it did strike me as a serious point of important information. That's a huge revelation indeed. Also, given how much more common earthquakes are -- not only in Japan but worldwide -- rather than giant tidal waves, it is extremely important to know that this sort of damage could result from earthquake damage.

It would make a huge case for closing many, many reactors.

If I recall, there is an earthquake of the same magnitude as the one near Fukushima about every year or two somewhere in the world (this could be the wrong amount of time, I can't recall now, but it was close enough in years to strike me as worrisome).

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.

    "it's possible that Unit 1 failed to scram properly."  Would this imply that they didn't get control rods in place to shut down the fission?  Do they use the 'control rod' function in these BWR's?  That might explain the 3-hours-to-boiloff if the reactor wasn't actually cooling down but running hot with a leak in the reactor.  Or am I reading that info wrong?

    about this:

Both the Mothership and the ROVs are for reporting and discussing the developing news. Neither space is for opinions or for editorializing on the subject of nuclear energy. The JNI team has decided that diaries which are not factual or which sensationalize this event are not included in Coverage@Kos

    no one can really know what the facts are, especially in this situation, so what is the point of these ROV's?

    who is the arbiter of facts herein???

    when a newspaper, cough, cough, publishes something it is a fact?


    i'm just wondering what good any of this is if a group of people here are trying to control what gets posted in this way.

    does this mean there are certain people not welcome herein as i have seen claimed?

    i've seen another diary in another group actively telling someone to get out a couple of days ago.  

    while i didn't necessarily disagree with that position, what exactly is going on here that any group of editors in any subgroup tries to control other posters in this way?

    i repeat: who gets to determine what are the facts?

    in fact, that is a futile exercise.  when will we all realize that?

    i got slammed for saying that fukushima seemed like it would be worse than chernobyl in the first week or so of the disaster.  but plenty of experts have said stuff like that in the intervening weeks.  as to what is really going on there, who the hell knows?

    my instinct is to believe we are looking at a nuclear stew that is going to be deadly for a long, long time.  that's my instinct.  it ain't fact.

    everyone now admits meltdown + has happened, but no one is at all clear about what that means.

    a blog is not a peer reviewed source, it isn't even a professionally edited source.  

    at least in a peer reviewed journal somebody on the masthead is responsible for what gets published.  

    i'm very discouraged by the 'cautions' above.  they simply don't make sense to me.

    •  My rule of thumb (10+ / 0-)

      here is to stick to details that have been released, link those whenever offering for the first time, and avoid too much hyperbole. Because these diaries are shared with people in Japan trying very, very hard to understand what's going on even while under a heavy hand of censorship (with reason, but it's still heavy). So they can make decisions that will affect their lives and the lives of their families.

      Promoting panic doesn't help anybody, even though none of us thinks the Japanese are overly prone to panic. They need calm analysis and reasonable discussion, not wild speculation.

      That said, I am someone with real-life experience in nuclear meltdowns and radiological monitoring of those. So what I think is entirely reasonable to propose and discuss, based on technical factoids that get out here and there, have often seemed like hyperbolic panic-mongering to people for whom all this high dudgeon sci-fi stuff is relatively new. I was one who wondered aloud just hours into our awareness of the event whether or not the scrams could have failed due to the earthquake, before station blackout. There was a 100% scram failure event at a (thankfully not at full power) reactor in Germany in 2002 (? could be later), when the entire core somehow got shifted in its seating so that none of the control rods could fall. That was a PWR, so was TMI where just the rod group ringing core central failed due to rod warpage. At Fukushima the rods are below the reactor, must be powered UP into the core. An earthquake could easily wreak havoc on that plan.

      I also wondered that first day about the amount of hydrogen they were venting, and was immediately lit upon by those who swore even as the buildings exploded one by one that hydrogen was impossible. Came to the conclusion that newbies to these sort of things really do get panic attacks if you say too much...

      The truth usually comes out in the end, after people have had a little time to get used to the ideas.

      Now, more than ever, we need the Jedi.

    •  Being clear seems like the first necessity (6+ / 0-)

      Are you stating a fact, a speculation based on available data, a speculation based on the absence of data or a speculation based on the poltical/human behavior factors?

      Are there other sources reporting what you are reporting and are they characterizing it in the same way?

      What is the knowledge or experience base you bring to the issue?

      While this is not a scientific or academic publication, this kind of diary and series of diaries (as with the BP Oil Spill series)  leans a bit in that direction given the nature of the event, the ongoing status of the event and the impact our comments can have beyond the keyboards.

      The "group-speak" issue is one that will work its way in or out over time, probably based on folks voting with their fingers if they think a group's restrictions or "management" are not appropriate.  

      One purpose I see in such "warnings" (though their enforcement is administered with a pretty light touch from what I've seen) is to minimize the number of useless painful marches to the right  through which we all must be dragged as we tread down that awful stairway while people throw spitballs at each other, devolve into idiocy and pull everyone off the topic - even if it is just long enough for us to scroll on by.

      I would encourage you to stay and see how it works and how it fits.  

      If it doesn't suit you, it doesn't suit you.  

      We'd rather dream the American Dream than fight to live it or to give it to our kids. What a shame. What an awful, awful shame.

    •  No one has ever been asked to leave from here (8+ / 0-)

      I have no idea why that disclaimer is up there. The group is a community effort. I want to go on record, putting my entire reputation on the line here, stating that NO ONE has been asked to not participate here ever (although we might have implied this by HR'ing a few people with obvious, cough, agendas... which probably lead to the disclaimer in the first place. Early on, we WERE badly trolled in early ROV's and MS's by some virulent pro-nuke folks and that probably was written then; I don't think I was an admin yet though).

      I've never seen anyone enforce it. The first time I ever lead an ROV, I thought I was supposed to and asked someone (a long-time friend) to keep on track. This was very funny, IMHO, and I quickly realized how out of line it was!

      Other posters have, at times, expressed discomfort with what someone or another was saying and if these conversations get heated, generally someone will ask it to be taken to p/m. I think that's happened like 3 or 4 times. Again, usually between pro and anti-nuke posters engaging in arguments about the benefits or drawbacks of nuclear power. That might also be what the disclaimer is about. Not sure.

      The rest, we try to make sense of the huge amounts of data that is all shuffled around the media, aggregating an amazing team of people from a huge variety of backgrounds. Anyone who wants to join in is totally welcome and encouraged to providing that they are interested in liveblogging Fukushima. No one would, or is, excluded from here.

      We have around 15 admins, 15 editors, and about as many contributors. Then we have a few hundred more regular posting participants here. We've had very, very little trouble in 56 ROVs. I am aware of having been told we are somehow preventing some postings here, since I saw these comments. I provided extensive information there as well as requests for links which showed that the poster was misinformed about who "JNI" was -- citing people who don't post here.

      I would personally get totally pissed off if I felt folks were excluded from freely posting here.

      My personal reason for posting here is to 1. bear witness to this tragedy 2. to share my compassion for other, future thyroid cancer victims 3. to document 4. to help piece through the media static and provide information 5. with the hopes that these things will eventually improve the situation, worldwide, with nuclear power in any way possible.

      I'm sure everyone else has their own reasons! :)

    •  We're all the arbiter of facts here (7+ / 0-)

      and kind of peer-review one another. If I post something bogus, for example, and you notice that it's bogus (say I screw up my math or provide a link to a source that's a RW source or something), you would politely correct me and there would really be no "argument," since those reading on would see that something was in dispute and was trying to be resolved. We disagree quite a bit here but are extremely civil about it when we do; some might not even notice if we disagree if they're just looking on since it really doesn't involve much name-calling. I think we all understand the intense collaborative nature of a project that is more important than our individual egos.

      I have strong knowledge about assessing research sources as well as media rhetoric; I'm also good at finding information online. These are my own particular University-level skills which I teach. In addition, I had thyroid cancer and know a lot about it. Others have other really excellent knowledge of other factors that are much more exceptional, moreover. Understanding of temperature and pressure gauges, mechanics, biological systems, meteorology, reproductive health, epidemiology, Japanese politics, etc...

      And some just care.

      I think we're a pretty awesome team and proud to get an Independent news source available; hopefully it can help Japan which is under heavy media censorship.

  •  Please listen. As the meltdown is official (12+ / 0-)

    (never thought I would be saying those words,) it is MANDATORY that we address some of the sequelae of this meltdown.  Please don't consider this off topic as the technical aspects are discussed.

    The reason I say mandatory is because every aspect of political power will be aimed at controlling the narrative of "the meltdown" and squelching information on this and as a last resort spinning it into a benign event.  This is the time to make a stand against that.

    I suggest that these diary series be expanded to include the questions on whether we are being protected from radioactive foodstuffs from Japan?  The lack of transparency of the position (or lack thereof,) that the US govt and other govts (Canada, e.g.) have taken on Japanese imports, esp. foodstuffs is breathtaking in its suggestion of collusion with the nuke industry and coverup.  We must not allow this to happen and we must protect ourselves.

    As I commented earlier in another diary:

    do we think that it is about time to INSIST that our government stop protecting the lying of the Japanese govt and the powerful nuclear industry, AND INSTALL A TRANSPARENT AND CONSISTENT SCREENING OF ALL FOODSTUFFS FROM JAPAN?

    do we think that that time has come?  OR SHALL WE WAIT FOR MASSES OF PEOPLE TO GET THYROID CANCER, ETC?

    And what the hell can we do about it?  The public information is inconsistent (see links below,) "these are not the droids you have been looking for."  And there doesn't seem to be sufficient public awareness about this to engender public pressure.  (Thanks to the handlers from the nuke industry.)

    The article in the NYT (tx, for the link, btw,) focused on the plant and safety.  Which of course is imp.  

    Focusing on this issue would, of course, raise the bar on awareness in the public about nuclear power.  However, I believe that that battle is an important one to fight.

    Do others think so?  Is that something we can do on this site?

    Some people are focusing on this and we should too.

    •  Meltdown isn't even a technical term (0+ / 0-)

      It's just a common word to describe partial/full melting of the fuel rods.

      No one doubts that some sort of "partial meltdown" occurred. The reason that a "meltdown," in the actual term, would be bad is that the superhot fuel rods could melt through containment and sink into the ground, which would be catastrophic. This clearly didn't happen in any of those reactors, or we'd know about it.

      And honestly, the "OH MY GOD TEST THE FISH, WE'RE ALL GOING TO DIE" panic is really annoying.

      We used to test nukes above ground IN THE CONTINENTAL US all the time. Sure, there were probably bad effects. Did it lead to massive death on a catastrophic scale? No.

      You're much more likely to die from driving to the supermarket than you are from some kind of Fukushima related cancer.

      You're much more likely to get cancer from your local car emissions/smog belching coal fired plant than you are from some kind of Fukushima related cancer.

      •  PhillyJeff thanks for the nuke lobby pov (10+ / 0-)

        You actually have made my point.  The very way in which you reacted to my post is how the nuke industry is going to react to any of these concerns.

        Anyone with legitimate concern will be ridiculed.  Thank you for demonstrating that as well.

        And honestly, the "OH MY GOD TEST THE FISH, WE'RE ALL GOING TO DIE" panic is really annoying.

        The nuke industry would love to know you.  You've got the messaging down perfect.

        Thanks for demonstrating my point more clearly than I could have.

        Instead, as I asked for, we need to have an open discussion about the levels to which we could be exposed and what the possible threshhold for health consequences: with transparent facts.  THAT IS THE MAIN THING I AM ASKING FOR.  I am one of the people who was made very sick from mercury in fish and I had to detox from it, which was not a pretty process.  Now I will not go near fish , since it made me so sick.  

        However, I am not the only one with this concern.  As I understand it, one of the main concerns is the accumulation of exposure to radiation from various sources.:

        Japan Finds Toxic Fish, As Ocean Radiation Soars To 7.5 Million Times Legal Limit  

        A fish was caught on Friday midway between Fukushima and Tokyo that contained dangerously high levels of radioactive iodine and high levels of cesium.
        This catch has prompted Japan to announce its first legal limits for radiation in fish, according to the AP. Previously Japan had said it was enough to ban fishing in the near proximity of the nuclear plant.
        Japan also just announced a huge surge in ocean contamination, as radioactive iodine-131 at 7.5 million times the legal limit was found near the plant, according to Japan Times. Yesterday, levels were only 5 million times the legal limit.

        Mother Jones is also all over this: fish and birds

        and here is a Daily Kos dairy addressing this same issue and asking for transparency on this issue:

        Should we go about consuming seafood (and seaweed) as if nothing happened?  Or should we insist on some type of monitoring of seafood from the Pacific?

        The simple "trust us... it's not that bad" just doesn't cut it.  And throwing in the risk of other events (i.e. automobile accidents, coal-mining accidents) does not help one get a true grasp on the radiological risk of this nuclear accident.

        •  we need to monitor all foodstuffs in the future (4+ / 0-)

          and should put a lot of pressure on our govt to do so.  Salmonella, ecoli, hormones etc. are already in our attention.  What is the real continuing food and environmental risk with the BP oil spill?  That, too, has been minimized from public attention.  

          Will the coverup be like the conditions at the WTC site at 9/11 which the EPA said was safe?  And in the last decade, the brave heroes are dying and suffering with all sorts of illness which clearly demonstrate the lie?  

          The radiation threat is not new.  Unfortunately, in the US there was a possible link to radiation in fish discussed w/re to the Vermont nuclear plant:
          Vermont Nuclear plant and fish

          There are so many powerful industries who are determined to prevent the facts from seeing the light of day and are derailing any serious discussion of risk.  Profit$, profit$, profit$!

          As the Japanese disaster has shown, the mechanisms for coverup are already in place and THIS IS WHAT WE MUST FIGHT AGAINST.  We must demand the information about what is happening and we must secure a place to assess the risks.  Of course, the favorite tactic is to attack the messenger and demean the consideration.

          I certainly don't know the risks.  But we need to have an honest discussion and assessment as we go along with Japan's worsening nightmare to protect our people as much as possible.

    under/around/near Fukushima would be an important thing to be aware of at this point, now that it seems pretty clear that the fuel is out of all its containers for, at least, 3 reactors.

    And how that affects water to other communities from village to large city.

  •  #3 acting up? (13+ / 0-)

    Unfortunately both data pages for the Fukushima plant have stopped updating. #3 was reported to have increasing temperatures since the start of the month and it's pretty well accepted now that all three reactors have melted their entire loads of fuel and have breached RPVs.

    From TEPCO latest update (PDF) they are injecting water through both the fire extinction system and the reactor feed water system. The way it's written is a little confusing but the injection rate may have been up to 14 m3/hr on the 14th. They also added boric acid for two and a half hours on the 15th and later that day upped the water injection rate to 9 m3/hr through each system, for a total of 18 m3/hr.

    According to JAIF the latest temperature for #3 is:

    RPV temperature (May 16 11:00)
    143.3℃*2 at feed water line nozzle

    This seems in line with the readings from the data page when they stopped updating on the 7th. There is no telling the accuracy of the readings though since they have had malfunctions with most gauges and the RPVs are full of crusted salt from the sea water injections. It's possible the fuel is insulated from the gauges and the water being injected. The actual readings are less important than the trend I'm thinking. #3 began generating more heat a couple weeks ago and they are dealing with it by injecting more water to hold the temps steady.

    So, more heat, more boric acid and more cooling water. Combining all that with the findings in FishOutofWater's diary linked above it all suggests #3 has some critical fuel somewhere.

    Improvement is change. Not all change is improvement.

  •  the earthquake damage is especially unsettling (12+ / 0-)

    given that the actual shake intensity at fukushima daiichi was far lower than at the epicenter offshore. it was more like a 6.5-6.8 than 9.0.

    there are a whole lot of reactors near faults capable of a mid-6s quake, southern california's diablo canyon and san onofre in particular. we need to do like the germans and do some serious review of our reactors' ability to ride out quakes in the 6s and 7s ASAP.

    •  Do you have info on the Germany process? (4+ / 0-)

      Our NRC's GI-199 process to asses implications of the recent (relatively speaking) revision of the seismic risk for nuclear power plants is supposedly incorporating the better historic and ground-movement data into assessing the level and frequency of risk and comparing that to various elements of the NPP design, construction and operation.  

      But there's an awful lot of moving parts in such an analysis that can be shifted one way or another by either the agency or the operators that affects the outcome.

      With the money invested and potential cost of back-fitting for new requirements on one hand and the newly highlighted complex and potentially catastrophic risks as we see in Fukushima, the pressures on both sides of that assessment were already high and are now even higher.  

      I'v looked at some of Japan's documents on their relatively recent reassessment of seismic risk and as I remember it was surprised at the level of "voluntary" assessment and compliance with testing and review.

      There seemed to be great deference given to industry and operator perspectives.

      I'm still trying to track back where I saw it, but I think the initial review here within the GI-199 focussed on core damage, not spent fuel pools.  I believe that after Fukushima, that has been changed but want to find out how much it changed.  

      I'd be very interested in more info on the German review (unfortunately hoping it will be in English as well.)


      We'd rather dream the American Dream than fight to live it or to give it to our kids. What a shame. What an awful, awful shame.

    •  Agreed 100% wu ming (7+ / 0-)

      This is definitely something that I've raised and, IMHO, warrants a shut down of the reactor at Diablo, as well as any other that might be on a fault line.

      Of course, I feel that all reactors should be shut down. But in this case, I can substantiate this claim based on solid evidence that a quake of a low magnitude can cause serious disaster to a plant.

      Also, there's the serious issue of U.S. reactor ventilation systems being inadequate that is just inescapable for justification of use.

  •  Steam limited stay time in #2 (10+ / 0-)

    Workers entered the Number 2 reactor building on Wednesday for the first time since a hydrogen explosion on March 15th. They tried to check radiation levels but left the building after 14 minutes because it was filled with steam, making further work impossible.

    The utility says the vapor appears to be coming from the damaged suppression chamber as well as from the fuel pool itself.

    Senior TEPCO official Junichi Matsumoto says he believes cooling the spent fuel pool will help reduce steam inside the reactor.

    TEPCO reports more than 90 percent humidity inside the Number 2 reactor building. Matsumoto says the building's roof is intact, making it more prone to filling with steam. Number 1 and 3 reactor buildings are exposed to the air because hydrogen explosions blew off their roofs and walls.

    •  #2 was never successfully vented (10+ / 0-)

      But by failing to relieve the pressure inside the reactor’s containment vessel, TEPCO is most likely to have allowed damage to be done to a part called the suppression chamber, which is linked to the containment vessel.

      In a venting operation, two valves inside pipes that lead from the containment vessel to the outside are opened to let steam escape into the air.

      According to TEPCO, the valves were opened at 11 a.m. on March 13, two days after the natural disasters struck mostly in the northeast, including the plant’s home, Fukushima Prefecture. But the pressure inside the containment vessel did not drop, nor did radiation levels go up in the surrounding area.

      Two more valves in a separate system were opened at 12:02 a.m. on March 15, but the pressure did not fall then either, according to the utility.

      Documents disclosed by TEPCO on Monday also show that the pressure did not drop inside the containment vessel. While the utility stops short of concluding in the documents that the venting had failed, the TEPCO source said the maneuver is deemed to have failed on both occasions.

      I guess then that the pressure built in the containment until something failed structurally. They think it was the torus.

      According to the article, there was a much larger release of radiation from #2 than from the other reactors.

      Others have simply gotten old. I prefer to think I've been tempered by time.

  •  A question for people who know reactors (5+ / 0-)
    Recommended by:
    stunster, rja, evergreen2, Just Bob, Wee Mama

    rja had a comment in the last ROV with a link to a TEPCO press release about what happened in reactor 1.

    Here's my question. Page 3 of the PDF has two graphs, one showing the level of water in the core of unit 1 and the other the temperature in the core. What happened? Or more precisely, what could explain the pattern shown in the two graphs.

    The water level started dropping rapidly right after the tsunami hit. The core temperature fell at scram right after the earthquake and did not start to rise until about 3 hours later, after the water level had dropped enough to expose about 20% of the fuel rods (by my reading of the graphs).

    Why did the water level drop so rapidly? If the core temperature did not rise significantly until the fuel rods were partially exposed, then was it possible for heat from the fuel to boil off roughly half the water in the RPV in about 2-1/2 hours? Or does the pattern suggest that there was a leak? And if half the water in fact boiled off, without steam being vented, would that not have caused the RPV (or suppression chamber) to explode?

    I would be grateful if anyone could provide an answer. Thanks.

    Workers have entered the Number 3 reactor building at the Fukushima Daiichi nuclear plant for the first time since a hydrogen explosion 3 days after the March 11th quake and tsunami.

    Tokyo Electric Power Company says 2 workers in protective suits and carrying air tanks went inside for about 10 minutes from 4:30 PM Wednesday to check radiation levels.

    Tokyo Electric Power Company says it detected 110 becquerels of radioactive cesium-134 per cubic centimeters in seawater samples taken on Wednesday morning.

    The level is 1,800 times the national legal limit, compared to 550 times, which was reported the previous day.

    The utility also found 120 becquerels of cesium-137, 1,300 times higher than the limit.

    Last Wednesday at the same location near the water intake of the Number 3 reactor, water contaminated with highly radioactive substances was found flowing into the sea from a pit. TEPCO says it detected cesium-134 at 32,000 times the legal limit.

    The Mainichi Daily News
    (Mainichi Japan) May 21, 2011

    The government has discovered thousands of cases of workers at nuclear power plants outside Fukushima Prefecture suffering from internal exposure to radiation after they visited the prefecture, the head of the Nuclear and Industrial Safety Agency said.
    Nobuaki Terasaka, head of the Nuclear and Industrial Safety Agency, told the House of Representatives Budget Committee on May 16 that there were a total of 4,956 cases of workers suffering from internal exposure to radiation at nuclear power plants in the country excluding the Fukushima No. 1 Nuclear Power Plant, and 4,766 of them involved workers originally from Fukushima who had visited the prefecture after the nuclear crisis. Terasaka revealed the data in his response to a question from Mito Kakizawa, a lawmaker from Your Party.

    The Nuclear and Industrial Safety Agency said it received the data from power companies across the country that measured the workers' internal exposure to radiation with "whole-body counters" and recorded levels of 1,500 counts per minute (cpm) or higher. In 1,193 cases, workers had internal exposure to radiation of more than 10,000 cpm. Those workers had apparently returned to their homes near the Fukushima No. 1 Nuclear Power Plant or had moved to other nuclear power plants from the Fukushima No. 1 and 2 nuclear power plants.

  •  nitrogen injection fails for 3 hours unnoticed @#1 (4+ / 0-)

    NHK reports briefly that

    On Saturday afternoon, a TEPCO worker found that the device to inject nitrogen, installed outside the reactor building, was not working. Injection later resumed using backup equipment.

    The injection was apparently not working for three hours.  

    It's likely the equipment can't be monitored except sporadically given the high level of radiation near the reactor.  

    It's somewhat encouraging to note that the utility company bothered to inform the press of this accident.  Not because I feel as though TEPCO is turning over a new leaf, but that incidents like this show that TEPCO doesn't trust the workers not to report directly to the press anymore.

    NHK has the manual and reports what we already have learned:  

    The manual NHK has obtained shows that the pressure inside the vessel was close to the level that requires a venting operation 13 hours before the explosion occurred.

    But the plant operator, Tokyo Electric Power Company, did not start the operation until 6 and a half hours before the explosion, and the operation was carried out just one and a half hours before the blast because it was hampered by high-level radioactivity.

    I'm not clear on the details, but the narrative has been emerging steadily now - the failure to vent was unorthodox and only partially explained by mechanical/electrical failures.  In the early days, TEPCO tried to blame Kan's photo op trip flying over the plant for the faulty timing, but that lie didn't hold.  Kan came back strong with clarification on that front.  


    I'm sorry I can't provide all the links to earlier stories, but in general these are all clues to the bigger picture - the "event" began with the earthquake, TEPCO dithered, hoping to conceal the full nature of the disaster (earthquake, not tsunami ruined the plant therefor all plants were unsafe) , the pressure rose both inside the reactor AND from the president's administration to vent the radioactive steam until it was too late (and the vents failed to open, anyway in many if not all cases) and then the reactor buildings exploded (and the coverup began in earnest).  What's UNCLEAR is who ordered the dithering, just as it is unclear who is in charge of decision-making now.  I can tell you one thing, though: a fish rots from the head.  

    •  High-level radioactivity before venting? (7+ / 0-)

      If true then,

      the operation was carried out just one and a half hours before the blast because it was hampered by high-level radioactivity.

      shows that the release of radiation was before the hydrogen explosion.

      •  This is the crux of the whole matter! (5+ / 0-)

        The NYT has come closest so far into telling the whole story.  

        It's an important story that needs to read in full by all concerned, and raises myriad questions that are thus far unanswered by TEPCO and Kan's administration both.  In other words, it's a scandal and a half and likely will be the focus of whatever investigation, if any, ever occurs.  

        But this is only chapter one, regarding the #1 reactor unit.  

        here is one small excerpt, just to be nice...  MUST READ STORY

        Government officials have also suggested that one of the primary causes of the explosions was a several-hour delay in a decision to use the vents, as Tokyo Electric managers agonized over whether to resort to emergency measures that would allow a substantial amount of radioactive materials to escape into the air.

        But the release this week of company documents and interviews with experts provides the most comprehensive evidence yet that mechanical failures and design flaws in the venting system also contributed to delays. The documents paint a picture of increasing desperation at the plant in the early hours of the disaster, as workers who had finally gotten the go-ahead to vent realized that the system would not respond to their commands.

        All of this information is coming to light in the wake of a document dump, documents which have NOT been released to the public but are currently in the hands of various major media corporations like the gray lady herself.  It's unclear what the timing and motivation regarding the document release is.  There is a war going on about how to spin this.  I don't know who the players are or what the next move is.  

        But I can't stress this enough - it's quite possible the delay in venting was FIRST and FOREMOST, an attempt to cover up the damage from the EARTHQUAKE, the pre-tsumani damage that shows how unsafe ALL nuclear reactors are.  Yes, this is conspiracy theory territory here but a completely valid line of inquiry that needs independent investigation.  

        Another 64 dollar question regards why TEPCO officials were in such close operational discussions with government officials over the timing of venting in the first place.  Safety dictates that you vent when the pressure becomes too great not to vent, not when it's politically expedient.

          "But a redesign of the venting system itself might also be necessary.

          The design is the result of conflicting schools of thought among United States nuclear officials, said Michael Friedlander, a former senior operator at several American nuclear power plants.

          Mr. Friedlander said, referring to the Nuclear Regulatory Commission: “You have the N.R.C. containment isolation guys who want containment closed, always, under every conceivable accident scenario, and then you’ve got the reactor safety guys who need containment to be vented under severe accident scenarios. It is a very controversial system.”

        Buried at the bottom of a Japan Times article is this explanation:

        The magnitude 9 earthquake on March 11 did not cause loss of cooling water at the Fukushima power plant, Tokyo Electric Power Co. said Monday, denying it played a role in the meltdown at reactor No. 1.

        "We have determined that water cooling the reactors was not lost between the time of the earthquake and tsunami," said Tepco official Junichi Matsumoto.

        Tokyo said it will submit a report to the government, attributing the meltdown to the tsunami and make it public Tuesday.

        The core of the No. 1 reactor melted within 16 hours of the quake, but high radiation levels inside on March 11 hinted the shaking damaged key facilities.

        TEPCO offers its standard denials, but the bolded section reports a "hint", almost certainly from an off-the-record TEPCO source, that probably comes closer to the truth: the high radiation that hampered venting operations probably was due to earthquake damage.
  •  To vent or not to vent (5+ / 0-)

    The this story concerns a warning from an engineer at a US plant that comes close to the situation in Japan. He was ignored and left the nuclear field.

    The back story here, concerns the tension between different groups of design engineers. The reactor designers want to protect their reactor by venting. The containment  engineers never want to breach containment.

    The proposal is for passive venting by use of a rupture disk. No power is required. Once the disk is ruptured, you've lost containment. It's a one time good deal.

    The concept is tempting, but I don't like the idea of the weak point in the containment being nothing more than a rupture disk.


    Others have simply gotten old. I prefer to think I've been tempered by time.

        •  So for short term radiation exposure (3+ / 0-)
          Recommended by:
          rja, Just Bob, evergreen2

          the issue is a slightly increased cancer rate (arguably... it depends on the rate...) and more notably possible radiation sickness if the rate is high. 20 mSv isn't so bad for a one-time exposure... a chest x-ray is around 50 mSv and a one-time exposure.

          But for constant exposure, well, you can see cellular mutations that result in cancers. For I-131, it would most likely be thyroid, but this easily metastasizes to the brain, the lungs, the lymphatic system, and the stomach (I think I'm forgetting a place; I know this from being checked for metastasis). It can also cause some neurological damage if this kind of exposure happens in utero. Cesium has its own set of separate cancers that it might cause. So too do other nuclides. However, they all cause "genetic mutation" potentially.

          If the rates have been that high or higher for two and a half months, I'd worry in particular about children around 8-11, whose thyroids are most rapidly expanding as the go through pre-puberty (if I recall) and also, newborns. I'd probably be generally concerned, however. Particularly since this doesn't seem to be clearing up. If it continues, I do believe we'll see a steep rise in cancer there.

      Well, yes, it's significant. The highest dose for infants (and a very high dose indeed) is under 100 mSv; in Tokyo, they didn't clear infants from drinking the water until it was under that level.

      I'm trying to find the SPEEDI link.

      If the exposure is continuous, and has been at around that rate since the incident, I believe there would be an increased risk of thyroid cancer or other thyroid-associated problems, like nodules which can cause permanent mental dysfunction in some children.

      If it's minimal, it still represents some risk to infants because their thyroids are rapidly undergoing cellular division and are more prone to anomaly's here. In utero can be especially bad as the fetus/embryo is vulnerable, although the mother's stomach provides some small barrier from the radiation.

      That rate is as high as the "raised rate" that Japan is letting some workers at the plant be exposed to. It's half as high as what can cause radiation sickness (1000 mSv) in some cases. If someone is half the body weight of an adult worker, presumably they would also be prone to potential radiation sickness at a dose of half this? I cannot recall if it goes by body weight or not, although I would think so.

    Workers entered the building on Monday. They shielded the heat exchanger to prevent high levels of radiation from affecting workers. They also removed walls that might hinder their activity, and erected a scaffold.

    TEPCO says it hopes to erect the columns next month and complete the reinforcement by the end of July.

    The water inside the pool remains hot, at around 80 degrees Celsius.

      We've learned previously that the basement is filled with five meters of toxic water.  No one has said if it is from the tsunami or the water they are dumping onto the building.  Nor have they adequately explained why the entire building went kablooey given that the reactor was off line at the time.  They floated a theory that hydrogen gas came through a pipe from #3 reactor building but that seems specious to me.  From the start, they have been cagey about the state of the spent fuel ponds.

    This story tells how, after WWII, Japan was pretty nuclear-phobic, understandably. And then,

    "This sentiment reached boiling point on June 1, 1954, when the United States conducted an atomic test in the South Pacific and a Japanese fishing boat was irradiated. The news sparked the strongest anti-American anger since the war. The U.S. wanted to dispel this resentment and — according to declassified U.S. intelligence documents cited by TV Asahi — found an ally in Matsutaro Shoriki, the powerful head of the Yomiuri Shimbun newspaper. Working with the CIA, Shoriki promoted the peaceful use of atomic energy as a means of "fighting fire with fire": Make the Japanese people tolerate America's nuclear deterrence policy by selling them on nuclear energy."

    The story goes on to tell how, via various industry-friendly tax structures and intertwining institutional alliances, things evolved until:

    "For the last 30 years, Japan has built an average of 1.5 nuclear reactors a year, the highest rate in the world, even though nuclear energy accounts for only 28 percent of the country's electricity needs. Though the government insists nuclear is central to Japan's economic well-being, what's important is the building of plants, not the production of energy. Construction benefits politicians and bureaucrats, while energy production mainly benefits power companies."

    Paris - Seventy thousand people living beyond the 20km no-go zone around Fukushima should be evacuated because of radioactivity deposited by the crippled nuclear plant, a watchdog said.

    Updating its assessment of the March 11 disaster, France's Institute for Radiological Protection and Nuclear Safety (IRSN) highlighted an area northwest of the plant that lies beyond the 20km zone whose inhabitants have already been evacuated.

    Radioactivity levels in this area range from several hundred becquerels per square metre to thousands or even several million bequerels per square metre, the IRSN report, issued late on Monday, said.

    Around 70 000 people, including 9 500 children aged up to 14, live in the area, "the most contaminated territory outside the evacuation zone", the agency said.

  •  Earthquake may have damaged unit 3 cooling system (6+ / 0-)

    According to the Asahi Shinbun (Japanese) the pipes in the cooling system of unit 3 may have been damaged by the earthquake, before the tsunami struck. From the article:

    According to TEPCO, after external power was lost due to the tsunami on March 11, at unit 3 another system [other than the Emergency Core Cooling System] cooled the reactor, but around noon on the 12th it stopped functioning. When they switched to using the high-pressure system after a drop in water level was detected the water level [in the reactor] rose for a time. Later, when battery power was used up, a valve needed to operate the system no longer could be opened or closed. The water level began dropping again and a major meltdown occurred.

    During the operation of the high-pressure system, the pressure had been around 75 bars inside the reactor pressure vessel but dropped to 10 bars in about 6 hours. Normally it would be difficult to explain such a rapid loss of pressure and TEPCO hypothesized that the pressure may have dropped because of damage somewhere in the pipes that circulate steam. The outcome was that the change in pressure roughly matched the level that was actually measured, so it is believed that steam may have leaked from the pipes.

    •  Anything to deny a meltdown... sigh (0+ / 0-)

      The timing of a pressure change at six hours also coincides with the timing of the meltdown, according to simulations.  Yes, a pipe could have burst letting steam out if the primary containment vessel but a molten fuel core could also have cAused the same drop in pressure if it burned a hole in the containment.  Given their track record of forthright communication (zero per cent) I don't think TEPCO's theories are the operative possibilities.
