Report: Maximum bulge in No. 4 reactor building 40% larger than previously stated in Tepco data

Published: June 25th, 2012 at 4:24 pm ET


The biggest bulge reported by Tepco in May 2012 was 33 mm. The biggest bulge now being reported is 46 mm.

Tepco’s latest data regarding the bulge in the No. 4 reactor building with translated summary by Fukushima Diary:

Tepco revised the data of the reactor4 building on 6/25/2012


The South-West corner of reactor4 building turned out to be bulged/leaned to outward.

The third floor is 46mm outward compared to the first floor. On their last report, it was 33mm.

    How does something as brittle as concrete bulge?
    Normally it would just boggle my poor little mind.
    Not so here. It is too scary to confuse me. It rivets my attention and makes me wonder about the people running this show, instead of the physical and chemical science of concrete.
    What is wrong with these people? Do they really want to start up more nuclear plants and try for a replay of this mess?
    Personally, I think corporate, military, or political leader should all be required to write letters to their great grandchildren, explaining why they felt it was okay to make a mess for someone else to clean up later:

    Dear Little Nodas of the Future;
    I started these reactors just so you could play in the dust and glow prettily in the dark…

    Perhaps we should all be satisfied with less than the obscene amounts of consumer products we have been educated to regard as a right.

    Sorry – I am ranting.

      Our Leaders are ALL in Nuclear Denial*….


      The illogical belief that Nature cannot destroy any land based nuclear reactor, any place anytime 24/7/365!

      • GeoHarvey

        And what is the likelihood that nature will destroy something?
        Do you suppose it might be 100%?
        Try this out for size. Westinghouse claims its new AP1000 nuclear reactor has a maximum core damage frequency of 2.41 × 10−7 per plant per year.
        With a little math, we can conclude that if 415 AP1000 reactors were put into service, we could expect one meltdown in 100,000 years. Pretty safe, wouldn't you say? (Grrr!)
        What is the margin of error for the calculation that produced this figure? What was the margin of error in the calculation that put a 5.7 meter seawall at Fukushima? Did the engineers take into consideration the tsunami of 1933, with its maximum wave height of 26 meters? Did they take into consideration the tsunami of 1896, with its maximum wave of 36 meters? Or did the engineers make a mistake?
        Did the engineers who calculated the core damage frequency of the AP1000 make any mistakes? As an engineer, I can tell you the probability that they made multiple mistakes is precisely 100%.
        Mother nature has an almost infinite number of ways to destroy anything we build, and will do so regardless of either calculations or feelings.
        I will admit that the likelihood of many of these possibilites is almost infinitely small.
        What this means is that the actual likelihood of failure due to natural causes is a number approaching infinity divided by a number approaching infinity.
        This number has no name – perhaps we could give it one: "Googoldygook." (A mantra for…

        • GeoHarvey

          By the way, speaking of financials. Solaria announced they were building an unsubsidized 60 MW photovoltaic farm in Spain next year, and expected to deliver electricity at $68 to $75 per MWh. The US DOE is projecting electricity from nuclear at $113.80 per MWh, not counting the costs of Price-Anderson liability, managing nuclear waste, loan guarantees, or tax incentives.
          Why do we even consider allowing pro-nuclear corporations to continue their rape-pillage-burn campaign?

        • Jebus Jebus

          My math says that, no matter the odds, the likelyhood of a nuclear power plant failing and causing massive radioactive contamination, becomes 100%, when one of them fails…

        • HoTaters HoTaters

          GeoHarvey, I'll rant too. The 26 meter tsunami was by no means the most severe in the past 200+ years.

          Note all the ones in Japan. Quoted from the article:

          "See also: Mount Unzen and 1792 Unzen earthquake and tsunami

          Tsunamis were the main cause of death for Japan's worst-ever volcanic disaster, due to an eruption of Mount Unzen in Nagasaki Prefecture, Kyūshū, Japan. It began towards the end of 1791 as a series of earthquakes on the western flank of Mount Unzen …. In February 1792, Fugen-daké started to erupt, triggering a lava flow which continued for two months…. On the night of 21 May, two large earthquakes were followed by a collapse of the eastern flank of Mount Unzen's Mayuyama dome, causing an avalanche which swept through Shimabara and into Ariake Bay, triggering a tsunami…. The tsunami struck Higo Province on the other side of Ariake Bay before bouncing back and hitting Shimabara again. Out of an estimated total of 15,000 fatalities, around 5,000 are thought to have been killed by the landslide, around 5,000 by the tsunami across the bay in Higo Province, and a further 5,000 by the tsunami returning to strike Shimabara. The waves reached a height of 330 ft (100 m), classing this tsunami as a small megatsunami."

          Note the use of the word "small", i.e., "small megatsunami."

          What are they thinking?

    • "Perhaps we should all be satisfied with less than the obscene amounts of consumer products we have been educated to regard as a right."

      No, you got that right.

    • Longjohn119

      They sure can. You have to realize that buildings such as these (and many roads and especially bridges) have an inner 'skeleton' of interwoven steel reinforcing rods. So even though the brittle concrete cracks the 're-rod' holds it together but can and will bend and bulge which OBVIOUSLY weakens the structure integrity severely.

      This is why the bulge is growing in size and will likely continue to increase until the weight is removed from the top or it collapses completely

    • razzz razzz

      Concrete really doesn't like vibrations (think jackhammers) but that is why they put steel and/or rebar inside the concrete to help it transfer and withstand flexing and vibrations or tall buildings and bridges would be falling down all the time. Concrete doesn't really like heat either, causes the cement to dehydrate and lose its binding properties.

      Once becoming off center, gravity takes over. If they start bracing the walls to keep them in place, you can start worrying for real.

    I love science. I love reason. I love people. I love heroes. I love art. I love nature.
    Once in a while, I have to rant because I find something so obscenely vile, so ugly, so careless of the damage it does, that I makes me very angry.
    The Peter Principle was developed by a man who observed it in nuclear power plants. I will paraphrase it here:

    Any dangerous but profitable activity will be used progressively more and more until it fails.
    If it fails sufficiently rarely, it will have an opportunity to become very ubiquitous.
    If it is sufficiently ubiquitous and sufficiently dangerous, it can produce failures that are widespread, even global.
    But if it is sufficiently profitable, its promoters will put enough advertising money into it to make sure it lasts until it is too late to have any effect but to wipe us all out.

    Human nature being what it is, people who want nuclear power would rather live in denial than face the fact that it is dangerous. That way, they can get rich while they are waiting for their Frankenstein monster to kill them.
    But their descendants will suffer through a number of generations, cursing their ancestors for their greed.
    Perhaps our generation will be the most cursed in history.

          • eatliesndie eatliesndie

            @dharmasyd. I of course agree with you. My point was, as well as being poorly stated – I can't stand debating. All it proves is who the best debator is. Some are good at it and can prove to others that white is black and black is white. There seems to be some ugly debating among the ranting at HP. I probably should have said nothing.

            • WindorSolarPlease

              Hi eatliesndie

              I totally understood what you said.

              However, there is a positive side to debates, when it's between two people who know the facts and who has the proof that's needed.

              I can see why people debate, it can change someone's thinking about nuclear power. If it changes one person's mind against it, it's worth it.

              I'm like you, I am not a debater and I usually stay away from things like that. I just say what I think, and then it's your choice if you agree or not.
              I'm human, I do appreciate it when people agree with me.

              I'm not a debater, I'm more like a cheer leader with the people who are against nuclear power.

              People who can debate, go get them. I would like to see more against nuclear power.

      Car driving isn't safe, but people are still drive cars and nuclear energy is much more safe than car driving.
      Everything is dangerous, nothing is safe.
      Death rates are lowest in nuclear industry including solar and wind:
      Coal killing much more people each year, when compared to death, caused by Chernobyl disaster.
      People are living in areas with higher background radiation for centuries and probably is healthier than these who live in lower background level areas:,_Mazandaran#Radioactivity.

      • BreadAndButter BreadAndButter

        Ah, dunno, it's you again. Last time you posted you claimed that low level radiation doesn't cause cancer, but instead prevents it. This time you spread the "acceptable risk" propaganda.
        This is wrong on so many levels, and I suggest you post your stuff on another forum, where people might be still uninformed enough to believe you.
        Here, they won't even listen.
