Question: Why didn’t Reactor 2 explode?

Arnie Gundersen, Fairewinds chief engineer: Reactor 2 did explode […] In Reactor 2, the containment exploded.

There’s definitely a large crack, perhaps 5 inches in diameter in the containment itself.

So the explosion occurred in Unit 2 inside the containment.

    Gundersen was a little nerdy but always good, thorough, precise. A woman was brought over from Japan, from the Diet, which is their Parliament. She quoted Fukushima Medical University as the AUTHORITY on childhood thyroid disorders ("just three cases of thyroid cancer), which was INFURIATING!! Nothing about 44%+ of the children having thyroid disorders! And at Fukushima Medical University, they make the doctors NOT mention radiation, NOT allow for second opinions, and they get fired if they are out of line with the Nazi rules. Her other answers were all timid and lockstep. So why did they bring HER over here? The man they brought over from the Japanese government was very impassioned and good, however. And the former Prime Minister, Naoto KLan was on videotape and strongly anti-nuclear. It's a mixed bag, but the conference is just starting. Troubled that some there want to KEEP nuclear energy however — even a man from the Union of Concerned Scientists — disturbed at that. Caldicott does not feel that way at all.

      Anybody who wants to keep nuclear energy is either feeding (profiting) off it themselves, or uninformed about nuclear energy's true nature…

      But then there is a wild-card…Someone who may be showing support for it because they have been strong-armed into having the opinion publicly…

        Helen Caldicott is amazing

      • moonshellblue moonshellblue

        Arnie has stated that he thinks nuclear power can be used safely thus I'm hoping he just said this once and has changed his mind.

        • Proton

          good point m… I haven't heard anything else about that from him…
          Being an engineer he has to be aware of the true nature of nuclear energy…

          So either he is group A or a wild-card…

          • I get the impression nuclear engineers DO know a lot about the true nature of nuclear energy.

            They DON'T know much about the epidemiology of nuclear energy, although Arnie would probably know more than most.

            (That's where the medical people come in -epidemiologists, doctors, Helen Caldicott, Janette Shermann, et al).

      david brenner is an absolute idiot. He was claiming that individual risk at fukeshima is low risk. Fukeshima is not low dosages of radiation.What a stupid fool Plutonium kills you schmuck…

        He's certainly ducking and weaving during the Q&A session.

        Hiroshima and Nagasaki survivors didn't have daily increased bioaccumulation and biomagnification exposure like we do now.

        It's like Ken Buesseler from Woods Hole. Where does their research funding come from? Timothy Mousseau was clear on possible career problems for those not reporting 'positive' results. I'll give him props, he's the only one risking his life regularly to get his info documented and published.

          —-> It sounds like David Brenner is basing his analysis on the Nagasaki/Hiroshima research from the —>

          "Radiation Effects Research Foundation" (RERF)

          which is touted as a "Cooperative Japan-US Research Organization"

          You have to decide for yourself if you believe studies coming out of a US/Japan research organization, since both countries highly promote nuclear energy.

          —-> THE ANNUAL FUNDING for RERF

          "is provided by the Japanese Government through the Ministry of Health, Labour and Welfare, and by the U.S. Government through the Department of Energy (DOE)."

          Now do you trust the studies coming from the RERF?

      44% of children with thyroid nodules, and climbing. 25% of children with thyroid nodules will develop malignant cancer, under 'normal' circumstances.

      5,000,000 children. 44% equals 2,200,000 children with thyroid nodules. 25% of that equals 550,000 children with thyroid cancer. 11% of children exposed to Fukushima radiation levels will develop thyroid cancer, to date, and climbing fast.

      Millions of cancers just in kids' throats within a couple of years.

      Good luck getting medical care.

      I was wondering about UCS … they seemed to downplay the issues in the beginning, probably just another extension of the feds now. Another "used to be hot" organization. Co-opts all over the place…

    I don't quite understand how a crack can be described as having a diameter…
    Could Arnie guess its length and width?

    Fukushima Daiichi is leaking radiation with no end in sight. Question is, where and when will the next nuclear disaster be?

  • Arizonan Arizonan

    David Brenner is an idiot – he never disclosed the numbers upon which his "risk estimates" were based, and he never seemed to get it that the Yablokov studies disprove the existing ICRC "risk estimates," which we assume Brenner based his pseudo science on, although he never tells us.

  • pcjensen

    the industry has thoroughly infiltrated the process. expect no big changes, unless the Pres himself flops and decides that, in the end, nucs are not worth our energy. right, I am a dreamer.

    Dr. Brenner was one of the scientists who helped set the guidelines for the full body airport scanners which become so controversial not only for the "naked" issue, but because of the amount of radiation people receive.

    To his credit he has backed off on the airport scanners by acknowledging their dangers.

    Good coverage of that issue here:

    "Brenner pointed out that X-ray damage does not hit all passengers equally.

    Recent research, Brenner says, indicates that about 5 percent of the population — one person in 20 — is especially sensitive to radiation. These people have gene mutations that make them less able to repair X-ray damage to their DNA. Two examples are the BRCA-1 and BRCA-2 mutations associated with breast and ovarian cancer, but scientists believe many more such defects are unknown. “I don’t know if I’m one of those 5 percent. I don’t know if you’re one of those 5 percent,” Brenner says, “And we don’t really have a quick and easy test to find those individuals.”

    SP: However, I am not as pleased with Dr. Brenner's early assessment of Fukushima's radiation risks to the public.

      March 28, 2011 Dr. David Brenner:

      "So, if we start with the situation outside the reactor, what we've been seeing over the past few days is a steady decrease in radiation exposure levels from a week ago until today. It steadily got smaller and smaller, which is pleasing and really does reflect the way the wind is blowing as much as anything, that the wind is still blowing the radioactivity towards the sea."

      SP: Ah yes….the favorable Kamikaze Fuksuhima wind….in the recollections of nuclear supporters it always seems to head out to the "vast" Pacific Ocean. In reality it doesn't always do that.

      Brenner: "But the short-term issues, I think, are not so important for the general population. The exposures that people are getting short term over the next days or even weeks, as it stands at the moment, are relatively small."

      Brenner: "Well, there are there are various sources that the plutonium could have come from. But I think we're relieved that the levels are actually very low, and actually, typical of plutonium — natural plutonium contamination in this country.

      So, right now, we don't have to worry about any biological consequences of that plutonium. There's a very small amount of it."

      SP: Doc…I hate to say it…but you're not a very convincing liar. You know that plutonium blew out of Reactor 3.

    Sorry to get offtopic from the Reactor 2 quotes from Arnie, but I am not always able to restrain myself. *;-)

    Back on topic…there was also a significant foundation building crack in Unit 2 discovered leaking 1 Sievert per hour water nearly 4 weeks after the reactor blew up:

    "Hidehiko Nishiyama, Japan Nuclear & Industrial Safety Agency said "Among the channels at the foot of reactor number 2 in the electric cable pit, we found water that emitted radiation in excess of 1,000 milli-sierverts per hour. There was also a 20 centimeter crack in the concrete at the base of the pit and we found that the water was leaking out to the sea through this crack."

    It isn't clear how much has been leaking from the pit into the sea. But experts say radiation is quickly being diluted by the Pacific Ocean and that even large amounts pose little threat.

    Meanwhile, the Tokyo Electric Power Company is planning to pour concrete into the pit to seal the crack. The operator will also use a mega-float to restore the tainted water."

    SP: Ah yes…the ocean is vast…bring her your tired weary masses of radiation yearning to be free…Mama Pacific will cleanse them all. (Not)
