Date: Tuesday, January 17, 2012 20:26 +0900 (JST)

[...] At the No.1, 2, and 3 reactors of the plant, the nuclear fuel has melted down, but the exact state of the fuel and details of the inside of the containment vessels are yet to be confirmed. This is causing a big problem for the operator [...] 

On Tuesday, 10 groups of 4 workers each entered the first floor of the No.2 reactor building from the northwestern side. The workers drilled a hole in the containment vessel to insert an endoscope. [...]

The utility says the workers were exposed to up to 3 millisieverts of radiation. The company says the workers had rehearsed the job at the No. 5 reactor [...]

it will insert the endoscope on Thursday as scheduled. It hopes to gain the first internal view of one of the damaged reactors since the accident.

    They should’ve drilled several meters further down, methinks. Can’t wait to hear them spin the story on Thursday.
    My guess: they “practised” on unit 5 to take and present some footage of fuel in a vessel.

      “My guess: they “practised” on unit 5 to take and present some footage of fuel in a vessel.”

      Unfortunately I agree with you. TEPCO and the Japanese Government have lied every single time they have opened their mouths, what makes this time any different? Also, funny they would ‘practice’ on a real-live reactor if it WASN”T so they could bull shit all of us. You don’t drill a hole in a reactor for ‘practice’. Even if it is supposedly empty. It will be interesting to see what some others think after the video is made available to the public…..

      They were supposed to make the reactor drink apple juice all night before inserting the probe.

      I guess I am the pessimist, my first reaction was, “oh @#$^%, reactor 5 has melted too!” Just sounds like the code Tepco would use, “rehearsed” at no. 5, yeah, yeah, “rehearsed.”

    Does this strike anyone else as insane? It’s going to be a stream bath in there what can they see in a radioactive haze? Talk about being in a fog! Nuclear power it’s safe cheap…maybe not

    Only 3 millisieverts? It must have been their their lucky day…

    “Trying to fine the melted fuel.”
    Certainly has and odd ring to it, doesn’t it?
    “Trying to find” should only be applied to car key’s, remote controls, office buildings and other daily routines.
    But nuclear fuel. Ah… it just does not fit the picture.
    Thus the common phrase… “What’s wrong with this picture.”
    Wonder if we will get to see the picture… wait a minute…
    This just in as we switch to the “Live” meltdown cam!
    I see “it”… there… is there something moving? What could it be?
    :o

  • Only 3? How did they measure that? With a dosimeter worn under a lead hat? Or with a dosimeter tucked inside of a lead apron, worn inside of three layers of clothes, away from any sources of radiation?

    Did they actually measure the radiation and record it, or did they just ‘estimate’ it, like they do with a lot of other things?

    Well, the air looks clear, not much steam, so let’s estimate that at between 1-3 millisieverts.

    Where is that 65 ton ‘Nuclear Boy’ off to now, anyway? He seems to have run away…

    • If the fuel really left the containment, then how would any water or fuel be left inside of it?

      Ten groups of four workers each exposed to 3 millisieverts each. How much time did they spend in there? Was it 30 seconds each? Was it 1 or 5 minutes each?

      They are not talking about how high the radiation levels are in there, so it must be really up there in the stratosphere. I bet they are all wearing lead suits.

      So guessing again, because no information is coming out..

      Full lead suits plus dosimeter UNDERNEATH the lead
      1 minute exposure per person; each drilling 1 minute
      40 workers; drilled roughly an hour using a pneumatic drill bit that can go through four feet of concrete in 1 hour.

      That sounds about right, kind of like Chernobyl, maybe worse.

      • It sure is a sad state of affairs when there are no journalists asking ANY questions…

        The rule these days seems to be to just regurgitate what anyone hands them and spit it out.. standard huge corporate machine operating procedure…

        Any grade schooler can do that. No need to go to college any more.

        Well now we know why, perhaps, they were shipping in busload after busload of white hazzie suited dudes, in between cop cars, fire engines, ambulances, and misc equipment. Seems there were a lot more than 40 workers just in the short clip Nuck provided; more like 40 per bus, methinks.

        Good thing it was in “cold shutdown conditions”. Otherwise it might have taken 41 workers, I bet, maybe even 42.

      Only 3…

      I think no. 3 because of MOX. It’hotter, and if some luck coriumis still in the vessel, situation of 1,2 and 4 might be better, and if it’s fully truth that MOX was used only no.3.Japan had ordered MOX quite a shit load already from AREVA

      Reports of radiation doses are ridiculous, not convinced at all. it might be a deadly of some workers, if someone dies, it’s because on flu or something.

      I live in Finland. Now Cesium is founded here also, distance is something like 4500 miles, lots of a shit on the plant region

    I don’t understand why they do this. It simply does not matter where the stuff is. They’ll never be able to get it out, so the only solution is to cover cover cover it with endless amounts of concrete, sand or whatever.

    And, for TV, build a fancy tent.

      Dear Tomb (cool screen name for ENE in the sardonic sense): I think about what they can do with the molten mass, too. I recall a friend from Holland who is a hydrologist that I knew in college. I wish I knew where to find him as he was very inventive though I have no idea if he has any ideas about this matter. I think, and am no expert on this sort of thing, that at the very least the corium must somehow be sonically (?) located. Then this needs to be drilled down to and injected carefully controlling ingoing and outgoing pressure to the mass [a very big problem--Areva can't detoxify anything apparently]to avoid creating yet another underground nuclear explosion. The corium’s I believe are likely fissioning helter skelter, and each time we allow them to have prompt criticality, the Plutonium is increased making the whole molten mass that much more volatile and sensitive to pressure changes. This is one reason I politely diverse from just covering the lava and forgetting about it, in favor of trying to glassify it, instead. What needs to be injected into the mix is, in my un-expert concept, magnesium sand and other neutron inhibitors that would encourage underground glassification if only to buy us a few decades of time, if possible. There has been, for example, glassification at Chernobyl for 25 years, which is now beginning to fail as the Chernoby’s corium is showing signs of heating up, even divided and spread out. If it’s not yet possible to do underground-remote glassification to buy time, then the talent needs to be immediately redirected and given the resources to invent something that made this or some other as yet unknown solution possible. There are 7B humans. The solutions are still there if we are alive. Under the current system, not inevitable, only 1% EVER in their lives have ANY access to higher education and the resources available to such people. Most people do not choose the sciences. This can change, virtually overnight.

    I think it will look like a scrape yard inside. I guess they want to know what big pile of rubble looks like.

    AGrennRoad is onto how it works. Practice is common, even on routine maintenance we practiced. Kinda like doctors, lawyers and dentists. They only have a specified amount of time to acomplish their tasks. (For example, when I was asked to do some welding out at Rancho Seco, we would go through the whole routine several times away from the radiation emiter. Most welding jobs were performed in teams with many jobs using in excess of 20 men. Normally, getting to the job, preparing the area for repair would take longer than the actual welding. After these types of jobs you could no longer work at the power plant, smud or bectel would pay big bucks for these jobs knowing they were going to burn you up for the year. And that was at a normally working power plant, not on that has aerosolized itself.

    How distinctly I remember Fukudai in all its splendor
    Til the quake and flood dismembered, corium, corpse on a floor
    Lying like there’s no tomorrow, vainly Tepco sought to borrow
    Bankrupt stealing our tomorrows, future now is of the yore
    See the bright and radiant burning Abbadon hails the molten cores
    Burning bright for evermore.

    “So quoth the Raven, nevermore!”

    Abbadon is the angel named in the Book of Revelation who holds the key to the bottomless pit.

    From Wikipedia:

    Abaddon (Hebrew: אֲבַדּוֹן‎, ‘Ǎḇaddōn, Greek: Apollyon, Latin: Exterminans, Coptic: Abbaton, meaning “A place of destruction”, “The Destroyer”, “Depths of Hell”) in the Revelation of St. John, is the king of tormenting locusts and the angel of the bottomless pit.[1] The exact nature of Abaddon is debated, but the Hebrew word is related to the triliteral root אבד (ABD), which in verb form means “to perish.”[2]

    Oh, my, have you seen this?

    Just when you’ve read of the latest debacle, the giant spiders “ulullating” in the dead countryside alongside the rotting corpses of the cattle and swine, wondered if the SPF #4 is really burning, if further criticalities are occurring, and now this …. No wonder it brings Abaddon (Apollyon, Exterminant) to mind ….

    BTW, I’m not in the habit of trying to emulate the brilliant Edgar Allen Poe. I just thougtht of “once upon a midnight dreary” and the rest just sort of jelled. So much for my attempt at poetry.

    What will it be next?
