Executive Summary of the Interim Report Investigation Committee on the Accidents at Fukushima Nuclear Power Stations of Tokyo Electric Power Company, December 26, 2011 [Emphasis Added]:

[...] Units 1 to 3 appeared to have automatically scrammed at the Earthquake, but external power supplies and almost all in-house AC power supplies were lost due to the Earthquake and the Tsunami. [...]

Explosions occurred on Units 1, 3 and 4, which were caused presumably by the hydrogen released from the possible core damage and filled in the reactor buildings. The reactor core of Unit 2 also seems to have been damaged, although the investigation is still incomplete. [...]

In the wake of the Accidents, quite a few cases were observed where the manner of providing information by the government gave rise questions and doubt on the part of the populations in the surrounding areas who were forced to evacuate and people in the whole nation that the government was not providing truth promptly and accurately. Such examples included, among others, the status of the reactor cores (core meltdowns, in particular), the critical conditions of Unit 3, and explanations on radiation effects on health such as “No immediate impacts on human health”, which was difficult to understand.

The following tendency was observed: transmission and public announcement of information on urgent matter was delayed, press releases were withheld, and explanations were kept ambiguous.

    “The following tendency was observed: transmission and public announcement of information on urgent matter was delayed, press releases were withheld, and explanations were kept ambiguous”

    That pretty much sums it up, right there.

  • “investigation is still incomplete”

    Should read …

    “investigation is still incompetent”

  • Lots of assumptions, guesses, presumptions, and wild stabs in the dark..

    Why not go in there and actually report on something factual for a change? Why not actually put in some radiation meters DOWNWIND and on top of the ‘vent’ tubes that are pushing all of the radiation high up into the atmosphere?

    Why not come clean and tell the world about what is REALLY going on at both DAICHI and DAINI, both in the spent fuel pools and in the reactors, or in the case of melt throughs, BELOW them.

    Telling the world you have achieved ‘cold shutdown’ is totally non factual when you do not know where the reactor cores are, whether they are inside or outside the buildings, whether radiation is being released or not, how much radiation is being released via water, air, ground, spraying on forest, dumping in Tokyo Bay, burning in sewage, etc.

    It is like crashing an airliner full of millions of people and not being able to say ANYTHING about it, other than assuming there is no immediate hazard to anyone.. Right… I can say that.. Except that if the plane blows up several times, is spewing Quadrillions of Bq of radiation, and has neutron beams, that tends to make me think otherwise..

    Claiming a plane is in ‘cold shutdown’ when it is still potentially burning out of control and releasing toxins everywhere is meaningless, useless, and potentially criminal.

    Trying to keep the lid on this is both insane and illogical at this point.

  • Trying to get the nuclear industry to come clean with actual facts and radiation release figures based on ACTUAL RADIATION METER MEASUREMENTS DOWNWIND is like trying to get an alcoholic to admit that maybe they have a problem… and need lots of help.

    Nope, no problem here… just crashed my car, which caught in fire and blew up, just lost my job, just divorced my wife and now homeless, but no problems here..

    Everything is JUST FINE.

    Geez! I think I read this all here at ene and even more months ago! Hey Japanese Govt., just contact us for info!

  • At least most large aircraft have BLACK BOXES that record automatically when an accident happens. How hard would it be to install black boxes all around every nuclear reactor in the world, powered by solar cells and batteries, so a ‘power supply problem’ would no longer be an excuse?

    After all, we all KNOW that a nuclear accident ALWAYS involves a loss of power, so they will NEVER have any radiation readings for ANY accident, EVER.

    How scientific is this anyway? I think a second grader could figure this much out, and do much better than these so called ‘experts’ as far as figuring out how much radiation is being released during an accident, after an accident and install them both downwind and on top of the ‘vent’ tubes in each nuclear reactor.

    Doing anything less seems to be anyway, to be criminally negligent, when millions and potentially BILLIONS of lives are at stake.
