Nuclear Engineer: New video appears to show molten corium that melted out of Fukushima reactor — “Some of it is still oozing” — We’ve been talking about criticalities going on and causing continued heat for a long time now” (AUDIO & VIDEO)

Chris Harris, former licensed Senior Reactor Operator & engineer, Feb 19, 2015 (at 30:15 in):

  • The buildings are really in a state of disrepair at Fukushima. There’s been some new video released of what could be the molten – some of the corium – that has leeched out. We talked a long time ago that some of it is not solid and still oozing in that respect. And this video showed something, that if it weren’t just metal melted, but it sure looked like if it was corium, then it would be oozing. Which would lend credibility to our lava lamp effect that we’ve been talking about for a long time now, thus little criticalities going on and causing continued heat… Certainly there were some pretty interesting images of it.
  • You can see how frustrating the attempts are to contain the mess into some area, let alone treat it.
  • The fuel was never designed to leave the cladding, that was the first line of defense. Once that gets broken and then the containment gets broken, or even before that the reactor gets broken, the genie is long out of the bottle.

    Otter, legislation in the works to store toxic nuclear waste in the Gem State

    Jennifer Brooks

    Despite the 1995 agreement created by former Idaho Governor Phil Batt that restricted nuclear waste movements into the state, current Governor C.L. “Butch” Otter formally agreed to support a U.S. Department of Energy plan to allow radioactive material into the state for testing and disposal at the Idaho National Laboratory (INL), starting this summer.

    But a number of political and environmental factors are causing concern, including the INL’s location directly above the Snake River aquifer, …

    OPINION: Take your dump and stuff it – elsewhere

    Posted February 24, 2015 in Front Page | Opinion

    The Bruce Nuclear generating station near Kincardine is currently the largest nuclear generating station in the world.
    George Mathewson

    Ontario’s plan to stuff radioactive nuclear waste into an underground cavern less than 200 kilometres from Sarnia has run into so much opposition that, with a little luck, might soon itself be buried.

    One of the latest to join the chorus of voices calling for a halt to Ontario Power Generation’s plan to build the dump less than a mile from Lake Huron near Kincardine is the City of Chicago.

    Mayor Rahm Emanuel, a man with more than a little political clout, said last month the proposal threatens the environment and public health of the entire Great Lakes basin, which holds 84% of North America’s fresh water.

    Sarnia, which is directly downstream from the proposed Deep Geological Repository, has formally denounced the plan. So has Lambton County. Scores of towns, counties and First Nations representing nearly 18 million people in Canada and the U.S. have also said ‘no’ to the dump.

    OPG has a history of bungling its communication with the public and this latest controversy is no exception.

    It said initially, for example, the repository would take waste with relatively low levels …

      of radioactivity, like workers’ rubber gloves. But last fall it changed its tune, telling the surprised members holding federal hearings that it wants to double the size of the dump to take waste from decommissioned nuclear plants, stuff that could stay radioactive for 100,000 years.

      Worse still, OPG acknowledged it never considered any other location but the one that now has millions of people up in arms.

      OPG is owned by the Ontario government, which owns 87% of the landmass of Ontario. Surely there are better alternatives out there.

      The proposal does have a willing host and a powerful backer. Many residents in Bruce County make their living from the Bruce Power nuclear plant, which is currently the largest nuclear power station in the world. Local municipalities will be handsomely rewarded for their support.

      OPG also has the Canadian Nuclear Safety Commission in its corner, the body that just happens to regulate the atomic industry.

      But given the size and spread of the public backlash, that may not be enough.

      The federal Joint Review Panel is expected to file its report in May, with the federal government making a decision later this year.

      The eight-unit Bruce Power complex provides 30% of Ontario’s power, at low cost, with relatively few problems, and zero carbon emissions.

      But it defies common sense to bury the toxic waste it produces and which will be dangerous for the next 100,000 years so close to Lake Huron.

      Yes, it needs to go somewhere…

    "Talking non-events, what’s just as scary as this Mashable post delivering the concerning news that Fukushima is leaking again? It’s the fact the accompanying photo (cue the urgency, a file shot from last year) says: “nothing to see here.” Maybe it’s a case of: don’t worry yourself what’s bubbling beyond the tarp? Expressive, too, are the numbers on the back of the safety uniform. Maybe this is just inventory data from the manufacturer or TEPCO procurement, but shades of stonewalling and bungling, it reminds me of an equation scratched on a tablecloth or the back of a napkin."

    Anybody see my lunch box?"

    MarkWW! Glad to see you…thought maybe you had succumbed to fatal pollution I the Big Enchilada! (Houston)

    But I doubt a neutron bomb has any merit in neutralizing the radiation loose at Fukushima. A link here:

    "…a leading nuclear physicist from NASA weighed in this morning with the following:

    *x* says that yes, neutrons do transmute uranium. The problem is that it will take a lot more than a neutron bomb will deliver. To do anything with that uranium, you would have to steadily bombard it for years with a high degree of neutron flux in a very specific part of the neutron spectrum. And in the process you will be creating radioactive products in the rest of the environment.

    He says the bomb idea is not good because the neutron flux will not be large enough and last for a long enough time to make much difference, you'll only get about 10% efficiency of the nuclear material contained in the bomb because the rest of it will be thrown all over the place, and you'll create a huge number of new unwanted nuclear products in the environment."

    SP: I think in the early days if they had attempted a neutron bomb earth pushing explosion to bury the entire island and the adjacent port (and brought in a flotilla of ships and airdrops to bury it all very deep) then they might have stopped the discharges. But that window of opportunity long ago sailed away…

    Are there any more pictures, the one provided are simply dirt + radioactive particles. Not a chance there corium.

    It's really nice to see people who have been here a long time likeS Sickputer and Heart of the Rose and of course MarkWW.
    You may remember BlueLight, he is/was my Dad. I posted awhile but had to give up, too busy with my SRS but I kept my eye on things.
    Both my Dad and I are Physicists so I'll do my best to inform where I can.

    Hugs for you all.

    INEPTCO know where the corium is, it simple, put a camera in the containment, which they've done, turn out the lights, cherenkov light from the corium would be easy to see, especially with light amplification. Even Tepco would have realised this, I hope.

    • Dr. Anne Lee Tomlinson Maziar Praising Jesus

      The coria was below all the concrete of the buildings quite soon after the meltthrough. It is now spread out through the porous sandstone and the millions' old lluvial fan river below the complex. Some has reached the ocean already, some may be travelling west towards the magma waiting to come up when a nearby volcano explodes. They undoubted;u know this through satellite imagery or other technologies available. But they will never say what they know. It would mean a long prison term. There is no freedom of speech any longer in Japan.
