Tokyo Professor: ‘Huge’ potential for harm from Fukushima contaminated water entering ocean — Warns of severe consequences

Title: Fukushima leaks 18 times worse than first thought

Some 400 tonnes of cooling water are being collected in tanks each day. The growing fleet of storage tanks — which currently stands at about 1,000 — is a source of alarm for experts, who fear that huge amounts of contaminated water will eventually have to be dumped into the ocean. Worse still, some 300 tonnes of groundwater highly contaminated with caesium-137, which has a 30-year half-life, are thought to be flowing from beneath the destroyed reactors into the sea every day.

The potential for harm is huge, says Jota Kanda, an oceanographer at the Tokyo University of Marine Science and Technology who monitors radionuclide distribution in sediments and biota off Fukushima.

“The effects of one relatively small leak may be insignificant,” he says. “But there are huge amounts of radionuclides in these tanks and the water may have to be stored for a long time to come. If more leaks were to occur the consequences might be severe.”

    It's not the little biddy leaks from the tanks that's the matter.
    It's not even all thewater in all the tanks.
    What's the matter is the thousand tonnes of groundwater that flows through nuclear fuel debris under Reactor Buildings1-4 and into the Ocean every day.
    That's the matter.

    Where is the damn corium, eh TEPCO?

    Potential to do harm, what is he saying, if you think things were bad yesterday just wait untill tomorrow, cause the damage has been done.

    hey hey my my
    Radiation will never die
    It's better to burn out
    Than fade away
    When you are out of the blue
    And into the black.
    Sorry mr. N. Young, please write us a song and get back to your roots, we need your participation. Please.

    there is an imminence of harm if no solution is found; there has been much contamination released. a prolonged continuation of release would surely kill us all in one generation.

    you know how it takes a shock equaling tnt to set off a nuke?… like a hydrogen explosion right?.

    can we use thermite to dilute the coriums into the surrounding rock?

    …sincerely, andy.


      @larry-andrew-nils: you'd only accelerate the rate of dispersion of rad-contaminants. As this are now, the coriums are basking in the surrounding water table; at least, that's the best conjecture. Some speculate that they've traveled deep (thousands of feet). I can't speak to their depth but would advise against attempts to either cap-off these rogue corium-induced 'fumaroles' or use of explosive dispersal of these corium masses.

      Keep in mind, these 'blobs' are not circular in shape but likely have assumed the formed of morphing vein-like structures. For this reason alone, any attempt to disperse them would be in vain [sorry…irresistible pun]…

    The article from Nature magazine is very fair.

    In July, Nature reported on the annual meeting of the “Society for Molecular Biology and Evolution.”

    In the article, Timothy Mousseau (the researcher from South Carolina who has been studying the ecological effects of Chernobyl and Fukushima) talks about how hard it is to get funding for low-level radiation research. 

    “…he says that US government grants are difficult to secure. The Department of Energy has largely stopped funding its research programme in low-dose exposure, and the National Science Foundation and the National Institutes of Health have awarded few grants on the topic. “The only people who seem to be doing any research are adventurous, opportunistic and independent,” Mousseau says. “They have some flexibility in what they do and are just doing it on their own without official support.” “

    Also, in the Comments section, there’s an interesting comment by a professor emeritus of Kyoto University —>

    He says, “I felt that the article title “Fukushima offers real-time ecolab” can be taken easily as if it was written by a ruthless journalist with hard-hearted observations, lacking consideration of the people of Fukushima who were forced to evacuate from their homes.”

    They stored the stuff and hid the truth until they could pawn off the stocks and lined up the liabilities into bottomless financial pits that stream away under layers of fluff from the guilty …

    So now, its time to do what they were always going to do.. dump it all in the ocean/s..

    After all, they do have paid scientists that tell them that it will all be mostly fine… And after all again, they are making the world a better place – people should realize this by now

    And "they" (the border-less) are now likely in position to make money off the fake clean up too..

    Perfection isn't it???….The simple beauty of it all..

    Remember, the rest of us are just "born everyday suckers" in their minds
