Nuclear Engineer who advised Prime Minister: Danger of radiation escaping from No. 4 fuel pool during strong aftershock — We don’t know what may happen if there’s another major quake — “We hope for the best” -AP

Hiroshi Tasaka, a nuclear engineer and professor at Tama University who advised the prime minister after the disaster, said the [Unit 4] spent-fuel pool poses a danger because the building is not sufficiently secure to stop radiation escaping in the case of a strong aftershock.


Tasaka said the government target of removing all the rods by the end of next year may prove too optimistic because of many unknowns, the need to develop new technology and the risk of aftershocks.

“If we are asked whether things are completely safe, we cannot say that,” he said. “If there is another major earthquake, we don’t know what may happen, although we hope for the best.”

    TEDxTokyo – Dr. Hiroshi Tasaka – 05/15/10 – (English)

    "..Dr. Hiroshi Tasaka says we are entering the age of invisible capitalism, a new paradigm in which invisible capital—knowledge, relationships, trust, brand, culture, empathy and more—will play a more critical role than monetary capital. The founder and president of Think Tank SophiaBank, a global network think tank that aims to change the paradigm of social systems, Dr. Tasaka also runs the Japan Social Entrepreneur Forum, an organization that fosters and supports social entrepreneurs. As a professor at Tama University, he teaches the philosophy, vision, policy, strategy and skills that social entrepreneurs need to learn. A member of the Global Agenda Council of the World Economic Forum, Dr. Tasaka was named president of the Club of Budapest Japan this year. The Club of Budapest, founded by Dr. Ervin Laszlo, has the Dalai Lama, Mikhail Gorbachev and Desmond Tutu as honorary members. Dr. Tasaka has written over fifty books…"

      Oh Arclight…Thanks for this wonderful link to the bio of Dr. Tasaka. It is thinking like his which we need to save us.

    "we hope for the best"

    I don't like it when nuclear engineers use "hope" as part of their solution. That's a red flag to me.

    • richard richard

      @enoughalready45 – true on that 'hope'. It's also a reason I don't like to use the word for the anti-nuclear movement. Hope does little. Action is the only factor that creates change … supported by knowledge.

      hes also a philosopher and poet.. ready for this…

      "..Then how can we foresee the future?

      By using “Dialectic Thinking”,
      We can foresee the future.

      Dialectic Thinking is the way of thinking
      Based upon the Philosophy of Dialectic.

      The essence of the Dialectic Philosophy is
      The Five Laws of Dialectic as follows.

      The First Law
      The Law of Development through “Spiral Process”
      The world develops as if it were climbing a spiral staircase.

      The Second Law
      The Law of Development through “Negation of Negation”
      Current “trends” always “reverse” themselves in the future.

      The Third Law
      The Law of Development through “Transformation from Quantity to Quality”
      When “quantity” exceed a specific level, the “quality” changes dramatically.

      The Fourth Law
      The Law of Development through “Interpenetration of Opposing Objects”
      Things which oppose and compete each other come to resemble each other.

      The Fifth Law
      The Law of Development through “Sublation of Contradiction”
      Contradiction is the driving force for the development of the world…"

    I hope I win the lottery.

  • I would prefer they did their best, rather than hoping for the best.

    Aren't R1, R2, R3, and R4 in that compromised condition?
    As is that tent stops radiation on R1?
    Like the hole in the secondary containment of R3 is good?
    Like the crumpled R3 can stop anything?

    Again I will say…
    … R1, R2, R3, and R4 have proved that the Mark 1 design IS flawed.
    No ands, ifs or buts about it.

    The FAILED secondary containment did NOT hold on all four.
    R1, R2, and R3 proved that primary contaient DOES fail.

    • Radio VicFromOregon

      Yes, but they are in the ground, or at least are now, but, headed for the groundwater, while SFP4 is exposed to air and wind currents and can release more radiation with no way to stop it. It has more radiation potential than all the reactors combined. But, additionally, if it goes, it becomes impossible to get near the R1, R2, R3, R5, and R6's for eons to come. They will all go even more critical than they are now.

    • dharmasyd dharmasyd

      Max1…Yes. That is all correct. This is why I believe we must ascend to a new level of thinking.

  • Heart of the Rose Heart of the Rose

    TEPCO deliberately tries to piecemeal the situation…
    This is a distraction from the composite condition of all the reactors..which is absolutely critical.
    This is a very purposeful distraction.
    They have full intent in blindsiding the people with radiation exposure.

  • Radio VicFromOregon

    It is my understanding that if any one or all three of the melted coriums continue to bore through the earth as slag, which they will likely do for quite some time, they can only recriticalize under very narrow circumstances because the particles lack the necessary space to fission. Yet, they will still not equal the destructive power of a fallen SFP4. They can all go exponentially hotter, and still not prevent people from continuing to work on closing this thing down because the radiation is driven downward and partially contained by the earth itself. Even if they hit the groundwater, some level of filtration will be possible, however inadequate, because we already have the technology to do that. Even a series of violent steam explosions would not equal the radiologic release of a fallen SFP4, however disastrous. But, if SFP4 goes, no work or containment will ever become possible for generations to come at Fukushima. ALL UNITS will go critical. Thick plumes of ionized radiation will go out and upward while the remaining solid rods will lay exposed in a smoldering radioactive fissioning pile, oxygen and space between the fuel rods allowing limitless refissioning and exploding. All anyone could do is stand from several, several miles away and look helplessly on. I don't know what TEPCO is doing, but the engineers are working their butts off on all 3 reactors and the SFP4. It's the media that focuses on one thing at a time.
