June 27, 2012 Tepco handout with summarized translation by Fukushima Diary:

Since 14:01 of 6/27/2012, the coolant system of SFP2 has been stopped. They confirmed the cooling pump of system A automatically stopped [...]

The water temperature was 22.9℃, it is estimated to increase at 0.24℃/h by Tepco.
Tepco states they confirmed no water leakage at 14:40, and the water temperature is under control.

    Well then it isn't there,then.Why else would you stop a pump in a Nuclear plant if there was nothing to save.First admission by Tepco. By the time they get to 4 it will be too dangerous and abandon it.

      I wonder about the Common SFP. That isn't talked about at all, and that was the largest one. But really, it's all moot now. 3,000 billion lethal doses released. Oh, heck, plus or minus a few 1,000 billion. What happens in Fukushima is really no longer of any real importance. Enough has been released to kill us all. Another 3,000 billion lethal doses will just accelerate what's already coming.

      What's important now is to face what's coming with dignity and fortitude. Those surviving the short term will have a lot to do taking care of those that won't.

      Thank you, to all the manufacturers, NPP owners and every bribed politician that let you cut corners. And don't forget GE was stealing taxpayer money through municipal investment fraud during this whole episode, most likely into the tens of billions. Criminals, all the way to the top.

    It sounds a bit blase, and doesn't give much information.
    Is there a System B that is still working?
    Do they propose to do anything about it?
    Or are they just telling us for information so we know our lives just got shortened again?

      There never was a Plan B, ever since this all started back in the '40s-'50s. The scientists figured science for safety/disposal would catch up. It never did, and never will.

      Just a small mistake.

    All these nuclear personal that Highly Promised there is absolutely no danger with nuclear plants.
    Where are they now.
    I think it's time to state an example. Bring them forth – and accuse them for this.
    If you don't state an example, they will just continue lying.
    It is not allowed to lie to a whole society –
    Where are they now –
    Chase them out (of their rat holes)-
    Accuse them in public –

    I do not mind the double post. I mean nobody knows how to fix this.
    I can quadruple this post if it would fix it, but why do you design something you cannot maintain in 40 years ? And after 40years you still cannot maintain it, and have to ask for a 20 year extension. Weapons were the only thing on their mind.

    Here, everyone take a piece of gum and start chewing. Take this roll of bailing wire over to SFP2. We've got to get that old pump going by sundown. Nobody throw up on the pump, please.
    It is easy to get discouraged by TEPCO arrogance, lies, and by their intention to force the restart of reactors all over Japan come hell or high water. I hate their Plan A. I hope the people of Japan, who have been too silent, for too long, pour into the streets to stop nuke restarts.

    Gotta love Senator Bernie Sanders!
    He knows that we cannot get the economy going again unless we rebuild our energy imfrastructure. Clearly, coal, oil and nuclear energy are NOT sustainable. Sanders said yesterday:
    "We also know that we can create a great deal of employment by transforming our energy system away from foreign oil and coal and into energy efficiency and such sustainable energies as wind, solar, geo-thermal, bio-mass and other clean technologies."
    Read his full oped in the Huffington Post.

    My thoughts in regards to the recent endoscope operation in fukushima reactor 1…
    Endoscope operation suggested the basement floor, where is used to torus room is flooded and the water level is 5m 20cm (17.06 ft) from the floor. The temperature was 37℃ (98.6F) near surface, and 34℃ (93.2F) near the bottom, where the atmospheric temperature was 28℃ (82.4F)

    American translation:
    Tthe basement is flooded:17 ft from the floor…
    While the actual Atmospheric temperature of japan is: (82.4F)
    The temperature of the water in the basement is: (98.6F)
    16+degrees hotter than outside the reactor…

    The only way that would be possible is if the fuel is below the reactor… (heat rises)…

    This means that even though the reactor 1 has been in a state of Cold shut down for nearly a year and a half, That the water in the basement is still above the atmospheric level Let alone hotter than the current temperature of the entire state of washington…

    Thats not even the worst news…
    The endoscope broke in mid service showing levels of 100,000~1,000,000 Sv/h before being addressed as malfunctioning…

    Our most highly developed tools for analyzing the radiation being released cannot even perform in the environment they were designed for due to the severity of the damages to this unit…

    Also: You cannot enter reactor 1, or you will be immediately poisoned with acute radiation sickness. While death will occur within an hour.

        Build a trench around Fukushima filled with zeolite? "Too costly." We are limited not by the creativity of engineers but by the inability to fund…..2 weeks around 10,000 Japanese surrounded the Prime Minister's home. Last Friday 45,000. They expect 100,000 this week….Japan has alternatives. They can engineer their way out of continuing to use nuclear energy like the Germans are doing.–Good news per Arne G towards the end of the June 27 interview by WBAI's Robt Knight: http://fairewinds.org/radio

      SFP2 has 81 tons of spent fuel, BTW.
      We are a bit OT here, Tacomagroove, talking about Fuku1. But this is a good jumping-off point for a discussion of just what is going on with Corium1,2,&3. The following is complete conjecture, just to get a discussion started.
      I am very surprised that the water in Torus Room1 isn't boiling. The corium probably left behind a heavy coating on every surface it has traveled through on its way out of the building. The radiation levels in Torus Room1 are way up there, as you might expect. Corium in pretty intense stuff. But the heat just isn't what I would have expected if the corium had exited through the torus, and burned through the floor of Torus Room1. So, I conclude that the corium exited through the bottom of the Containment1 instead. Perhaps a small amount of molten corium overflowed into the torus. You would expect this overflow corium to keep water temperature in Torus Room1 elevated. So, let's say Corium1 is now about 60' below the building, in bedrock. Let's say the interior temperature of the corium has cooled to 1,500 degrees F by now. A crust has formed on the exterior, where the temperature is, say, 300 degrees F. Let's also say that the hole through the bedrock that Corium1 passed through is filled with water. There are holes in the bottom of the steel torus, and water being pumped into Containment1 by TEPCO has filled the Torus Room1 to a depth of 17'.

        [Con'd]
        So, the corium may not have exited through the torus, but instead burned its way through the bottom of the containment, through the base below, and through the building floor. Now, we have a bus-size blob of corium 60' deep in bedrock, with a water column of cooling water and ground water up to the Containment1 floor. Shouldn't the corium be generating a lot of steam? Yes, but the steam arrives at the surface of the water column as bubbles of gas. This is probably what we are seeing coming out of the open corner of the tent TEPCO built around the remains of Building1. Any thoughts on this? You don't have to be a nuclear professional to have an opinion on this. This is new stuff to the entire human race. So please weigh in.

          All fuel rods melted in reactors 1, 2 & 3 and settled at the bottom of their containment vessels in April, 2011. So the melt through the basement you are envisioning has happened in all 3 reactors. Your explanation is well thought out and interesting, Philip. Some parts of the cores may have reached the ocean by now. Some people think if it ever gets into the earth crust, it will dilute and fission will stop.
          Perhaps not, because the uranium fission chain reaction can be sustained as long as an external neutron source is present that the fission can grab. Everything is made up of atoms and all atoms have neutrons. #3 & #4 have MOX fuel rods that are not affected by water at all once they enter fission…no cooling and saltwater makes it hotter!! A plutonium (MOX) fission criticality is self sustaining.

          About unit 4, it takes about 2 months to remove the rods in a normal situation. Removing the rods in #4 is not going to be a fast process. Since they think some rods have melted in #4 probably not all of the rods will be removable.

          I appreciate the brave and honorable men that work on these reactors. They deserve medals for courage.

    Yes Phillip the corium will have left a coating of particles everywhere it touched or water took it. If you look at the history of core melts you find it will follow a trajectory that gravity takes it, but it also leaves traces everywhere.

    Loose extremely hot particles would be taken into the torus area by the path of water, but larger particles and parts of the fuel would have fallen through the pressure vessel into the drywell basement. Some of the fuel probably melted and then hardened again inside the pressure vessel. Some was transferred by the water into every pipe, pump and system in use. A lot of the corium probably still sits in the drywell basement, with some of it melting into the concrete below.

    So the torus would not be the worst place for dose rates or nuclear inventory. If there is 15 feet of water on the floor there the dose rates mean that no human will ever enter that area until all the cesium has gone through 10 half lives at least. That's about 350 years.

      "A lot of the corium probably still sits in the drywell basement, with some of it melting into the concrete below."
      Hot 3200 degree F corium sits on the basement floor. And it just stops, and stays there?? Brother, are you one of Them? Because you can't be one if Us!

        I think the corium's burning bedrock is what produces the very black smoke seen spewing from the ground, I hope I'm wrong.

        all due respect phil, i believe chris is trying to help.

        he has alluded to be a nuke industry insider before. i appreciate some inside professional info.

        i think i understand your angle as well, i know i've reacted to info that doesn't seem right.

        it's been mentioned a couple of times that a new commentator or an alternate view has been 'attacked' here – i've probably done the same.

        just a thought, but maybe if more views are accepted, even passively, we may gain better insights that we need.

        The likes of DanialKalns and 'dunno' press bigger buttons then Chris.

        sorry, i'm blathering.. it's a delicate issue and hard to put into words. and i don't want to be any 'thought police'. i just wonder if people should be cut a little more slack sometimes.

        just saying.

          My contention is that the positions of Coriums1,2,&3 matter.
          My contention is that Coriums1,2,&3 have left the buildings, and sit in bedrock below Fuku.
          If you have evidence to the contrary, I'd like to hear it. Hell, if you even have a good theory why a concrete basement floor under water could stop a corium, I'd like to hear it.

    is the ring torus made of plate steel, or is it made of re-bar re-inforeced concrete that looks like an egg shell struck with a sledge hammer? of course the plate steel didn't stop the melt-out. the plate steel would help with the continuing earthquakes.
