The camera we used today can resist for 1000Sv, but even the camera got so much noise (the white spots), the radiation level is really high. At usual reactor test, we put water-resistant camera into the reactor but it gets too much noise when the camera goes close to the highly radioactive place called top guide.

Happy20790 ハッピー

If you put the camera at too radioactive place for too long, the camera gets broken. Today the endoscope became like that. To get more detailed image, we would need a more protective camera. It would cost 100 million yen to buy the camera what can get close to the fuel debris with color image.

For the next time, we need to develop new equipment. We shall use the same hole to measure the radiation level next time. We can’t even tell what to do if we don’t know the radiation level inside.

      There’s a limit to how far an actual image could be carried, down an optical fiber bundle. Then there’s light-losses to deal with. Problem is, there are no existing solid-state imaging devices that can withstand the level of radioactive bombardment that such devices would be subjected too, in this environment. I’m just stunned that they wouldn’t have know this right off! It’s as though there going through the paces…to save faces.

  • If it is so safe and in cold shutdown, have one of the bosses stick their head in there with a flashlight. Surely they can find a pinhead somewhere that can squeeze their tiny brains through a small hole like that?

    They have not measured the RADIATION?

    Well, cause it don’t exist! There is NO RADIATION after you achieve cold shutdown, dont ya know!

    Everyone knows that you cannot measure something that DOES NOT EXIST!

    Chernobyl had readings in 1-2 months after the disaster, and once they got over their uppity-ness, allowed other governments to track their plumes, too. That was in the frickin’ 80′s. Now this and it’s been HOW LONG and it seems like NOBODY knows what the heck is going on over there, not even their workers sometimes. This is insane.

    Reminds me of the out-of-control Macondo well that is still going and NOBODY knows what’s going on there… but at least there, BP got a camera (for a while) while all we could do is watch in horror… the Tepco cams are so far away that they show nothing… at least with oil you can SEE IT… Radioactivity… nadda.

    Yes, I’m furious. We’re about to get pummelled with up to 6 inches or more of snow here in NW Ohio/SE Michigan… we’re right in line with the same jet stream that Oregon and Washington State are getting.

      Sorry for your situation Chelsea. The advice that I’ve seen from others is to consume foods that are lower on the food-chain. The higher-up you go, the greater the bio-accumulation of toxins; not unlike what you find with mercury and fish. In this case, we’re going to be getting hit from every direction and every effort must be expended to push-out the inevitable. Someone suggested awhile ago, that this (Fukushima) may be an intelligence test; that only the intelligent will take measures to keep themselves minimally exposed and maximally informed. Such wisdom can only be found in sites like this. Enenews is da’bomb!!!

      Chelsea, you can get calcium bentonite clay. Put half a teaspoon in water and drink twice a day. Put it in a pan of water and use it to wash any food that may have been exposed. You can also put half a cup in a tub of very hot water, soak for 20-30 minutes to remove it from your body surface and to leach it out of your body. You can also soak clothing in it. Other substanes to use: apple pectin (used at Chernobyl) or zeolite (this can be very good for entry way to dissolve in water and wash off boots, etc.). And of course, fresh miso soup and seaweed can be helpful as well. Be safe!

          Quick tangent: doubtless, they’re (ISEC) using a combination of fiber-lense-fed technology, where the actual imaging array is shielded from radiation, while the actual image is brought to the array through dense bundled fiber-optics. The fibers themselves could be ‘doped’ to attenuate the incident gamma rays.

          @harengus: It’s impossible to carry images over long distances, within a flexible light-guide (fiber) medium. You can carry light, but as any opto-tech will testify, the integrity of information being carried by the light becomes subject to the transmission media. This is why pulse shaping and optical transponders are required for such applications. When you attempt to carry images down optical medium, the issues become even more complex. The refractive-index of the light-carrying medium conspires to blur the image as the light (information medium) travels farther down the ‘tube’. Add angular changes (flex) and it becomes impossible to get any ‘intelligence’ on the receiving end of the fiber bundle. If you’re looking to retain image integrity, then you must employ imaging array technology. Fiber is confined to ‘pin-hole’ type uses and then, only over short distances. There’s more but I don’t want to ‘bore’ you further…

              @aigeezer: your guess is correct. The problem with semiconductor-based imaging arrays is with the amount of energy that the valence structure of the sensing cell can handle before the symmetry of the sensing structure is disrupted. This phenomena is attribute to ‘ion migration’. A hot particle (gamma particle) smacks into the sub-atomic structure and rips uniformed particles out of place. This can cause everything from benign bit-toggling to irreparable damage to the semiconductor cell. When you pack billions of cells close together, to achieve higher resolutions, the problem grows exponentially. CMOS-based Charge-Coupled-Device (CCDs) are the most common imaging technology in use. I’m not up on the latest developments, so I’m sure other electro-optical technologies could be used. However, until more robust semiconductor technologies are developed that can withstand ALPHA and GAMMA particle bombardment, they are not going to bringing images back from deep inside that reactor. I have made suggestions (in other adjacent posts) on how I think they could develop workable solutions. Otherwise, TEPCO should stick to making excuses…

            I disagree.
            You need pulse sharping and optical transponders if you want to transmit huge datastreams. Pictures are different.
            In fuku you need a bunch of fibres, one for each pixel, additional ones for the light plus one lens. No need for electronics on the “hot” side.

              @harengus: I’d also have thought they’d have considered this avenue. The amount of ‘noise’ in these images is evidence that the electronics (imaging array, signal processing, mechatronics, etal) are in the head of the flexible probe. They’re likely steering the probe-head with fly-by-wire mechanical actuators (flexi-wire?). Then it’s only a matter of slowly moving deeper-and-deeper into the complex. Doubtless power, control signaling and returning data-streams are being delivered through the flexible cabling.

              Hopefully, we’ll learn more of their ‘strategy’. If we’re not too preemptive in our criticisms, maybe someone will grace us with more information…

      @Auntie: though I’d have to sympathize with those who are opposed to earth-bound-nuclear-powered-energy-generation-systems, I was not aware that enenews was an ‘anti-nuclear’ site. From what I’ve gleaned from many of these posts, some of the more prestigious (and informed) posters have had (or currently have) backgrounds in nuclear energy and/or physics. From my readings, I’ve gleaned that the enenews ‘crowd’ is very unique, in that they are able to interface at all levels. For those who are to hammer-out new paths and policies, this venue offers an invaluable opportunity to ‘talk’ with the truly experienced. This is a far cry from the techno-firewall that the public’s been forced to endure over the last seventy years.

      Personally, I’m pro-nuclear – just not earth-bound nuclear! I believe that research (and deployment) of nuclear power systems should continue – just not within our planet’s biosphere! We also need to ramp-up research and deployment of environmental remediation technologies. Unfortunately, those who’ve preceded us have left much damage in their wake. Which also becomes an awesome opportunity (both intellectually and economically) to those of us who care…

          Sad fact is, due to the proliferation of nuclear power plants, it’s not feasible to ‘plug the plugs’ as it were. We’d have to implement a program were no new licenses are issued and no operating extensions are issued. While those existing plants are still operating, alternative energy systems would have to be brought online to supplement what’s being taken offline. To ensure that no shenanigans come into play, a zero tolerance rule would have to come be upheld. This rule would stipulate that under no circumstances (wartime or otherwise) will any nuclear plant be allowed to operate beyond its shutdown date. When it’s understood that the return on investment will be measured against the cost of decommissioning timed-out facilities, nuclear power will be abandoned as being economical – in any sense. Keep in mind, when the true cost of nuclear power is measured against property loss, health costs, environmental impact and lost or diminished human productivity, no one will want anything to do with it. Such abandonment will fuel alternative energy technologies and innovation. Not so coincidentally, all our technology is evolving towards more efficient use of energy. What we have seen in the way of environmental neglect over the last century also promises incredible commercial potential for those who expose the true costs in mismanagement of technology.

            Addressing another issue: thanks to our life-giving sun, millions of tons of highly radioactive particles pass by our thinly veiled atmosphere. If I’m correct, we are afforded protection through what is known as the Van Allen Radiation Belt. It is an electromagnetic field, composed of radioactive particles that resonant with the passing gasses of the sun’s corona. These particles resonate with the impinging solar radiation which are then essentially deflected past the earth. Some, obviously, do get through to bring life; others…sterilizing death.

            When it comes to nuclear power, there is nothing that matches what the sun throws at us every second. As our planet is a finely-evolved (tuned?) entity that resonates with perfect equilibrium in our galaxy (notice I don’t simply confine it’s evolution to the solar ‘system’), it is important that we not expose it to levels of radiation that it cannot assimilate within a practical life-cycle period of all the organisms that it shields. Simply put, we cannot overload its metabolism with toxins. The more exotic the toxin, the more difficult it is to neutralize (metabolize) their effects on resident organisms. We now know that the earth is a living organism. Our failure was in not understanding this fact until now.

            Which brings me to why it is safe to use nuclear power in space, with the proviso that it not, under any circumstances become risk to the planet. This means that every precaution must be taken in conjunction with its use in space. No orbiting power platforms should be built. And those power stations that do exist must include self-destruct fail-safes. We need to be thinking – way – outside the box.

      I wonder often about “happy”. We’re told he works for Tepco, but he doesn’t fit the profile of a down-and-out contracted day-laborer. He sounds like he’s been at the site for a long time and knows his way around. This doesn’t seem like someone who may be exposed to life-threatening radiation on a daily basis. He seems to show up whenever something fairly big is going on at the plant, which might mean he is fairly high in the pecking order – a low-level worker might be given a bucket-emptying know-nothing assignment for months on end.

      I wonder about his motives, his loyalties, his worldview, his agenda (if any).

      I wonder why he seems to be the only one of his kind that we hear from regularly.

      Don’t get me wrong – I’m not accusing him of anything bad – I just wonder what kind of critter he is. If Tepco were clever (they don’t appear to be), they might plant such a source to increase fear, uncertainty and doubt in the public mind. So might other interested parties. Now I’m sounding like a conspiracy theorist – no, I’m just getting more and more wary as this high-stakes calamity drags on.

    The truth is… they were using #3 to re enrich plutonium. the facts are coming out. that’s why the big bang in the pool, and the following day, the one that shot-gunned into the earth from the core. It killed the 6 folks who were poking there heads in it, sadly. The corium is what caused that big black radioactive & toxic smoke event. As everything then burned in the bowels of the plant. This was followed by the ground cracks and caused the radioactive steam/smog/fogs to happen.

    Follow the paper. The rods come from Arieva in France, the plutonium came from the old USSR disassembled warheads! The Japan military was building a bomb when we dropped our on them. Few months delay, they would have had one.

    This way, they don’t have to deal with a political slam from building a urainium enrichment plant. (Notice that’s what gets folks upset in other nations?)It also explaines the blackout, and fallout compleately!

    Now… the pool of four has more than DOUBLE the new rods in it, the full load just pulled out… to refit #4 to do the same, and all them older rods ALL PACKED TOGETHER!

    They don’t know just how bad a BANG it would be if it went up, as nobody ever had such massed-together fisionables sitting about like that!

    We tried this in the USA, but NEVER in a WATER cooled core! And even then? We almost lost Chicago!

    This is usual TEPCO bullshit. the lights and camera at the end of the endoscope are in the operator box, they are connected to the end of the probe by fiber optics. Because of this the pictures should not be fogged with gamma interference. TEPCO has added this after the inspection.
    If you want to see nice clear pictures of melted down core look at simi valley melt down, TMI melt down and Chernobyl.
    Unless the operators where in a multi sievert environment during the 70 minute inspection.
    I couldnt understand why they didnt switch off the lights and look for the eerie blue light from the melted fuel.
    Keep up the good work, one and all.
