[…] “If you calculate the amount of cesium 137 in the [Unit 4 fuel] pool, the amount is equivalent to 14,000 Hiroshima atomic bombs,” said Hiroaki Koide, assistant professor at Kyoto University Research Reactor Institute. […]

[Unit 4’s reactor building] may have tilted and was bulging after the explosion […]

Corrosion from the salt water will have also weakened the building and equipment, [Murray Jennex, an associate professor at San Diego State University who is an expert on nuclear containment and worked at the San Onofre nuclear plant in California] said.

And if an another strong earthquake strikes before the fuel is fully removed that topples the building or punctures the pool and allow the water to drain, a spent fuel fire releasing more radiation than during the initial disaster is possible, threatening about Tokyo 200 kilometers (125 miles) away.

    The Japanese Government needs to come out and admit this is beyond their expertise. It is time they put a call out to Scientists throughout the World, and bring in outside opinions. This is how Chernobyl got control of their situation.

    • obewanspeaks obewanspeaks

      Chernobyl, is not under control/will never be under control, and they only covered this forever radioactive leaking cesspool!

      Scientists have recently discovered that the radioactivity is not going down per the stated decay rates, therefor either the plant is still leaking/out of control, and/or the original decay rates published for manmade created radioactive isotopes was a blatant out right lie from the get go!

      These people would never lie to us…would they?

      Has there ever been profit in truth is the real question..

      I do not think so…

      • PhilipUpNorth PhilipUpNorth

        If my observations are correct, Mr. Obewanspeaks, then the scientific community is dead wrong. Fission in corium just seems to go on and on, with heavier and heavier accumulation of fallout all over the northern hemisphere.

        "Decay heat" is the cooldown heat caused by nuclear fuel after the fission process has been shut down. In a reactor, control rods are inserted into the reactor fuel, bringing new fissions to a halt. "Decay heat" still happens for many years as the isotopes continue to decay, turning the unstable atoms into more stable daughter elements. This is the theory. But I have concluded that fissioning in corium can go on and on, meaning that nuclear fuel corium fission just "never" shuts down. Radiation levels from Fukushima seem to be going up and up, with no end in sight. This is happening, even when one or more of the coriums may have melted deep into the rock under Fuku.
        Just look at Radiation Network readings for the US since 311. I have asked RadiationNetwork to use their new graphing tool to show us the steady rise of readings from all stations since 311. Most stations registered an "elevated level" of 10-15cpm at that time. Now, these stations are averaging readings in the 30-50cpm range. I hope that Radiation Network can soon provide a graph of this uptrend in radiation readings over the US as a result of Fukushima.

          That's so NOT true. Any benevolent alien would know who to pick up and who to leave behind. That's sort of "the thing": The world is filled with good and evil, and evil too often seems to win. But higher powers still know the difference between right and wrong. I know that a lot of people are agnostics — I relate to that. I just don't think that we are alone. Will it help in our current straits? Well, that I can't answer. Just that compassion MATTERS. It will always matter.

  • davidh7426 davidh7426

    Does anybody know which genius thought it would be a good idea to put a 'cooling pool' at the top of the building and not at ground-level in an earthquake zone, where the only direction that the pool can go is down ??

    And just how many more monstrosities of this design did they build, and where ??

    • captndano captndano

      Not sure of the genius' name, but I believe that the design was first adapted for nuclear submarines in an effort to save space.

      • nedlifromvermont

        captndano … I believe you are right. It was a Westinghouse design which they used for the Nautilus (first nuke submarine) and which the rich General Electric Company bought (J P Morgan banking syndicate always the largest shareholder in GE) to roll out the U.S. light water reactor program;

        … and using tactics one could conservatively compare to pre-putsch Nazi behavior in the Weimar Republic parliament, bullying, character assassination etc. these total capitalist screw ups, with monopoly protection and heavily subsidized by government dollars and limited liability protection …

        forced onto the marketplace … keeping the submarine configuration for spent fuel storage because it SAVED MONEY (and space) and not because it was safe …

        … and spent fuel pools only were ever supposed to hold at most one or two cores worth of fuel bundles, but the CORRUPT NRC/AEC never forced the issue, regulators might not receive fat checks to Swiss bank accounts, or a cushy position at an "industry" job with fat $$ benefits (yes the nuclear village is alive and well in U.S., too) and no pressure from NRC STILL TODAY to defuel and dry cask these pools (now with many cores worth of fuel) (Arnie Gunderson was a spent fuel re-racking specialist for Chrissakes)

        and Allison MacFarlane DOING NOTHING TO ramp up pressure on industry for dry cask "campaigns"

        and so they are ALL OF THEM toadies, liars and absolute SCUM

        and there you are!!!

        peace …

    • We Not They Finally

      davidh7426, GE were the “geniuses” who designed this monstrosity.

  • Nuclear Catastrophes aren't like other disasters.

    They usually get worse as time goes on. (can be a long time too)

    When there's a tornado, earthquake or flood, the disaster strikes, then it subsides and it's rebuild and recovery.

    With Nuclear Power is just a scramble to prevent it from becoming far worse.

    Q: How much worse can it get?
    A: Much!

    Q: How much worse will it get?
    A: Unknown! (high probability, it will)

    🙁 Considering the Pacific Ocean has already been turned into a toxic toilet and the atmosphere is being loaded with more radioactive contamination than we can imagine on a daily basis, I'd say we're off to a pretty bad start on this one. With no plan and no end in sight.

    The tilting fuel pool that contains 14,000 Hiroshima bombs worth of cesium (and other stuff)is just one of the multiple immediate problems facing all of us.

    What’s ASTOUNDING is that the first announcements, a week or so back, were that the radiation in the ocean had spiked 50-fold! Then there was “we don’t know why.” Then there was…… SILENCE?? Don’t we need to know?? Because something clearly HAPPENED which had not HAPPENED before. What was it?

    • Anthony Anthony

      Tepco has a consistent habit of ANNOUNCING an actual problem as if it is a future event, when time and again we learn it is a current event. My money therefore is on Number Four has sunk and spilled as well as the overflow pacific issue they are warning about has actually happened.

      • We Not They Finally

        Yes, SOMETHING caused the ocean radiation to suddenly spike 50-fold.

Our spent fuel pools are not safe & Congress would put a few billion to ensure that our own plants & fuel pools are updated & safe!

    Now time has run out on doing what should had been done 2 years ago, removing the rods is a death wish, not doing so is also, no wonder the government of the USA has made it all most impossible to leave this country, you have to be super rich with contacts, what a sorry bunch of people we have sent to DC!

    6). "At the highest levels: There is plenty of evidence the White House knew everything and played a ‘lead’ part. In the Osendorff email he clearly states that “NRC posture to hold White House lead for U.S. response, NRC to be support only so as not to focus media attention on NRC-”. Again, in a March 12th, 12:52 PM email from David Lew, we see White House involvement: “NRC remains in the monitoring mode. Chairman attended a meeting with White House. Marty Virgilio participated by VTC.” (video teleconferencing)"

    Later that afternoon another email from Mr. Lew states that there is a “Deputies Meeting at the White House with significant focus on the nuclear event.”

    I love the way 'they' refer to dangers on the sites a separate issues. Buts its actually a house of cards – pull one and it all comes down.

    SFP 4 leaks or a criticality occurs while unloading – the pool catches fire – they will have to abandon the site. Then cooling fails progressively everywhere else on the site when unattended plant breaks down or power fails, and we loose Japan if not the northern hemisphere.

    Any of the buildings collapse, ditto.

    Someone makes a mistake driving a crane and drops some debris though the bottom of a SFP liner, ditto.

What, a civil war era gun boat with crane mounted??? Or maybe a really big barge??

    The fuel rods from the still-intact Chernobyl reactors 1 to 3 present another problem. About 20,000 radioactive fuel rods have been kept in temporary cooling ponds for years. The nuclear experts fear that these wet-storage facilities are now more dangerous than the ruined reactor itself.
