They’ve Found the Missing Fukushima Nuclear Cores … Scattered All Over Japan

They’ve Found the Missing Fukushima Nuclear Cores … Scattered All Over Japan thumbnail

We reported in May 2011 that authorities knew – within days or weeks – that all 3 active Fukushima nuclear reactors had melted down, but covered up that fact for months.

The next month, we reported that Fukushima’s reactors had actually suffered something much worse: nuclear melt-throughs, where the nuclear fuel melted through the containment vessels and into the ground. At the time, this was described as:

The worst possibility in a nuclear accident.

But now, it turns out that some of the Fukushima reactors have suffered even a more extreme type of damage: melt-OUTS.

By way of background, we’ve noted periodically that scientists have no idea where the cores of the nuclear reactors are.

And that highly radioactive black “dirt” has been found all over Japan.

It turns out that the highly radioactive black substances are likely remnants of the core.

The Journals Environmental Science & Technology and Journal of Environmental Radioactivity both found (hat tip EneNews) that the highly radioactive black substances match fuel from the core of the Fukushima reactors.

The U.S. Nuclear Regulatory Commission agrees.

Indeed, “hot particles” with extremely high levels of radiation – 7 billion, 40 billion , and even 40 billion billion Bq/kg – have been found all over the Fukushima region, and hundreds of miles away … in Tokyo.

Let’s put this in perspective. The Atlantic notes:

Japanese regulations required nuclear waste with 100 or more bq/kg of Cesium to be monitored and disposed of in specialized containers.

 

***

 

The new government limit for material headed for landfills is 8000 bq/kg, 80 times the pre-Fukushima limit.

So the hottest hot particle found so far is 5 million billion times greater than the current government limits of what can be put in a landfill.

In other words, the core of at least one of the Fukushima reactors has finally been found … scattered all over Japan.

How did material from the cores get dispersed so far? Remember, there was a huge explosion at reactor number 1 , and an even bigger explosion at reactor number 3.

    It may not be too far in the future when from the nuclear radiated waste of Japan’s coastal waters a new and terrible problem will arise — Godzilla!! Genetically mutated from the fabled Puffer Fish, Godzilla will self-inflate and float across the Pacific Ocean on a tidal wave of its own making, to reek havoc and mayhem on Hollywood and great Los Angeles metro area, all the better to show everybody just how dire the Fukushima disaster really is.

    If it self inflates, he be just right for congress.

    I wasn’t sure whether to believe this as this is a significant statement and then the picture shown here is not nuclear fallout but the tsunami spread, so I went to Arnie Gunderson’s website. There he has a video presenting scientific evidence of finding highly radioactive core particles in various places in Japan far away from the Fukushima site. http://fairewinds.org/hottest-particle/

    The hot particle theory is back from the dead! 🙂

    And the nuclear beat goes on…

    Abe is trying hard to get a war with China going so the financial disaster and Fukushima is swept under the rug. Or so it seems from the news in the East. “O” even said the US will stand by them when/if it happens. Another country trying hard to start WW3 to cover up all of the BS going on in DC these days and to cripple the EU, Russia and China.

    … and what, exactly, does a map of tsunami wave heights have to do with radioactive contamination in japan?

    TEPCO and the government of Japan were not open and honest about this disaster from day one.

    There needs to be independent confirmation of any information coming from them.

    Nuclear energy is an environmental nightmare………
    TEPCO has a 40 year plan to clean up the disaster at Fukishima but admits that some of the technology to clean up the site has not been invented yet.

    It is time to transition to safer, cleaner and cheaper alternative energy sources. Had this been a wind or solar energy site it would all be cleaned up and back in service by now and all the evacuated people would be back in their homes.

    The Nuclear industry pushed nuclear energy as “too cheap to meter” but really gave us a technology that was too costly and environmentally damaging to exist.

    Not exactly good news for the Japanese population or the nuclear industry. No alternative for, well, alternatives (solar/wind).

    This post says, “So the hottest hot particle found so far is 5 million billion times greater than the current government limits of what can be put in a landfill.” This is a completely FALSE and MISLEADING statement.

    If you watch the video for the hottest particle referenced by the 40 billion billion Bq/Kg link, the actual measured radioactivity for the particle was 310 Bq/Kg, which is about 26 times less than the 8000 Bq/Kg landfill limit.

    If you take this one dust spec that can only be seen with a powerful electron microscope and multiply its weight times a big enough number to equal a Kg, your going to get a really really big number, but even this does not make sense. If the vacuum cleaner bag instead of having this one “hot particle” contained a entire Kg of Cs134, based on the specific activity of Cs134 which is 48 TBq/g, the measured radiation would be 48 PBq, which is still a thousand times less than the 4 followed by 19 zeros number mentioned in the video.

    Yet another reason to switch to molten salt reactors which shut down passively, can’t go re-critical or explode in an accident and don’t build up fission products.

    Nuclear energy is too costly and too dangerous.

    It is time to speed up the transition to safer, cleaner and cheaper alternative energy sources.

    Quick thanks to Dave B and drwater.

    Once one understands how incredibly small a becquerel is, something apparently Arne Gunderson doesn’t (despite having worked in nuclear operations), it puts the story in it’s proper context.

    As Dave B stated – the story is completely false and misleading.
