Experts assuming Reactor 2 had cracked containment vessel that allowed releases directly from melted nuclear core — Radioactive plume was blown south (VIDEO)

Title: Causes of largest radioactive leaks may be found
Date: Jul. 24, 2012 – Updated 12:35 UTC (21:35 JST)


Among the 4 reactors at the Fukushima plant, the No. 2 reactor leaked the largest amount of radioactivity according to nuclear disaster monitoring.

Researchers from the University of Tokyo, the Japan Atomic Energy Agency and other experts have examined the crisis response log at the reactor facility.


They found radiation levels rose sharply 3 times at monitoring posts 10 kilometers south of the plant over a period of 5 hours during the night of March 14th.

These rises came 1 hour after each time workers at the No. 2 reactor released steam from the core to lower its pressure. The plant employees did so to protect the reactor.

But it is believed that by that time the nuclear fuel in the core had already melted down and its containment vessel was also full of radioactive substances.

The experts assume that the radioactive plume escaped from cracks in the containment vessel after steam was released from the core. It was carried south by the wind.

They say the amount of the radioactivity leaked from the No. 2 reactor was 10 to 20 times higher than other reactors, following their hydrogen explosions.


If No. 2’s radioactive release was “10 to 20 times higher than other reactors, following their hydrogen explosions”…

And if the radioactive plume from No. 2 “was carried south by the wind”…

How did 80% of the radioactivity get blown east over the Pacific?

    The only way to keep giant killer plumes from passing through unsuspecting citizens is to not use this dangerous technology at all. 100% fact.

    It did 't.

      Scout, are you answering admin's delicious question:

      "And if the radioactive plume from No. 2 “was carried south by the wind”… How did 80% of the radioactivity get blown east over the Pacific?"

      If not, I'm not sure which part of the story you're referring to.

      Great question, either way.

      … or so we're told. Their inconsistencies are showing more and more.

    Let me get this right they knowingly released radioactive steam and did not enact emergency procedures as per IAEA mandate, did not activate speedi,don't tell me they did not know how radioactive steam was, very hot, the engineers at that time had little or no options, but must have known that the fuel was exposed due to readings.
    I guess at the time they figured that if the situation continued to spiral out of control, then it did not matter we are all dead and did not want to cause world wide panic.
    So kind of them to spare us the burden but I am sorry to say we would like to know, at least we could try.

    • GlowInTheDark GlowInTheDark

      NPP all over the world does regular 'vents' and releases radioactive steam…that's a fact unfortunately.

      But what's more frieghtening is that 29 out of 54 NPP in Japan has the same design fault as in Fukushima that it does lead to hydrogen explosion should it be vented :O

      Source? Hodo station did a report on this.

      • weeman

        But this steam must have been extremely radioactive and they knew that and did not follow protocol to warn people, that is criminal they have a mandate that they signed.

    • Exactly!!! Another hero, he says it like it is.

      They tossed the contaminated spilled fuel into the ocean at the Rokkasho Reprocessing Plant after a leak. I never even heard of that one.

    Are we seriously supposed to believe Reactor 2 released the most radioactivity! :0)) Get real! What about the explosion at #3 which blew half of the core into the atmosphere and the fire at #4 fuel pool?

  • razzz razzz

    That is the problem with Unit 2, it stayed together other than blowing out one side panel which saved it from trapping hydrogen and exploding the building.

    All it's fuel load wasn't spread around and is still able to react with itself, making possible more radioactive poisons, locally. Units 1 & 3 self destructed, sending fallout around the world but partially stopped the interaction of the cores' fuel. It is said Chernobyl blew 25% of its fuel load into the atmosphere, leaving the rest to turn into radioactive lava and now, radioactive dust.

    Anyway, that's the working theory not counting the MOX fuel in Unit 3's core. And if Unit 4's pool fuel was exposed, it is back underwater now.

    Hard to say what is really going on since they keep playing hide and seek with the results of the fallout readings plus keep revising what has been released.

    Don't worry, smile, be happy.

      Dont forget Reactor 1..the silent quietly emitting mess of corium..leaking into air and sea…

  • dosdos dosdos

    The detonation at Unit 3 was not a hydrogen explosion. NHK is still either believing the lie or perpetuating it intentionally.


    it should be obvious – now – why they shutdown the rad-monitors…

  • razzz razzz

    Notice how they blame the 'workers' at the plant for venting. Must be some really really smart workers making decisions about how to handle nuclear emergencies and not TEPCO and its nuclear engineers.

    Anytime a nuclear plant vents (or leaks) from the core, either done through manual or automatic controlled releases, the venting is radioactive. What do they think is going to happen? Lower radioactive readings?

    Venting didn't save any of the reactor cores. They all melted down.

    So a balloon that goes bang releases less air than a partially deflated balloon with a slow leak :0)) Very droll…

    • razzz razzz

      I told you there was a working theory about Unit 2 producing the most radioactive fallout and the current articles here on ENEnews are Japanese government reports stating this is exactly what happened and is happening.

      The three meltdown Units continuously leaking their poisons, have the capability to destroy the entire Pacific Ocean. That has not been reported yet.

      BTW, the tall, tall venting towers that sit alongside the Units are tall for a reason, so any venting that takes places through those towers carries the radioactive fallout away from the plant to prevent contamination of the immediate are so workers can continue.

      Of course, leaking, manual venting and explosions of the cores couldn't use the dysfunctional tower outlets at the time since a lack of power at the plant disabled the necessary valves to be opened for venting through the towers plus any damaged plumbing to the towers.

      They lost control of the plant during the power outage with no possible way to cool the reactors. Venting at the time really didn't help.

    @rambojim…That's what Ronald Reagan said to Dr. Helen Caldicott when Reagan's daughter, Patti Davis, took her to meet her father and talk about the nuclear danger.

    With his disarming charm, Ronnie greeted Helen saying, –Oh yes. You're the woman who saw "On the Beach as a little girl and have been afraid of nuclear energy ever since.~~~

    Disarming through charming, friendly ridicule! And we still live with the results.

    • rambojim

      @dharmasyd…The US could use another Ronald Reagan today…

    • razzz razzz

      In Dr. Helen Caldicott many lectures, she points out that Reagan didn't have a clue about the dangers of anything nuclear. She had to educated him on the spot in the White House. Also prediagnosed him being in the early stages of Alzheimer's disease (dementia) along with estimating his IQ being around 100.

      • Reagan was hired to do a presidential impersonation, he really didn't know much about anything, except to have a vague neocon ideology. He was one of the least accomplished actors in Hollywood, he was successful because of his looks. I am sure the PTB did a lot of market research before they gave him the job. Reagan, of course, started the whole looting of America machine in motion.

    One of the ways to lie with statistics about the radioactive mess from Fukushima is to not mention what you aren't measuring. YOU are only measuring the air, at certain times on a certain day in a certain place. YOU are not measuring the air at other times and other places, and YOU are not measuring the ocean and not measuring the groundwater, or the soil, nor the…so, YOU can say, Unit 2 released more radiation because YOU only give measurements for the short period for when this was true. So, it's a very distorted truth in your mind rather than an outright lie. However, by the next day it was not true. But, of course, you don't mention that either. This works for many in the media, many in government because grasping the more complicated reality requires learning about all the ways radiation moves, and all the radioisotopes, and all the levels, and, well…that is simply too complicated. I often think the the issue of underreporting is not really just about TEPCO's corruption, unscrupulous government officials, and a lazy media, but, about how really stupid most in positions of power and authority really are. It is very, very easy to trick these people because they believe that their positions give them special insight like being able to see though walls or understand the nuances of nuclear physics hypotheticals vs realties or know what is best for people.
