    Notice it says:
    “Status: Instrument failure”
    is this the measuring instrument? or the reactor?

  • Okay so is it safe to conclude then the emissions have also risen accordingly by five times in the same seven day period?

    You are making a big mistake.

    It’s not “japan” that changed the data. It’s the website !

    The original data from tepco website were not changed !

    Everything is explained here :

    http://www.physicsforums.com/showthread.php?t=480200&page=504

    **************
    The graphs on that site are not good, plenty of errors.

    For a start for unit 1 they say that one CAMS reading is from D/W and other from S/C. Its not true, both the sets of data they are showing are for D/W, and they are not showing any S/C readings. TEPCO publish 2 D/W readings and 2 S/C readings, and it is important to note that the unit 1 D/W readings were unavailable for many days due to presumed sensor problems, and indeed the sensor that has recently shows 201 Sv/h has also spiked to high values in the past, so dont know whether to trust it.

    As for Units 5 and 6, the site is complete rubbish, it is using wrong data. There are no CAMS readings for reactors 5 and 6, and I have worked out what data it is using by mistake. These numbers are the reported temperatures of the spent fuel pools at units 5 & 6 and should certainly not be in Sv/h. Here is the raw data that I can get to match up, eg look at pool temps at 12:00 on 21st and they match the bogus Sv/h readings on that graph site:

    http://www.tepco.co.jp/en/nu/fukushi…data_56u-e.pdf

    So I would not recommend using that atmc.jp site, use TEPCOs data.

    http://www.tepco.co.jp/en/nu/fukushima-np/index-e.html

    As for why some of the real numbers are also high, well this equipment is inside containment and is designed to detect fuel melting, so its not surprising that some numbers are high. Yes if many of these higher numbers were from outside containment then this would indeed be cause for great alarm, but they arent, so dont panic.

    With all of the water they’ve been pouring into the (leaking) reactor, wouldn’t there be water even in the drywell? Why aren’t we seeing steam?

    Reactor No 2 is very steamy, so its obvious the corium is in water. But No 1 and No 3 are hot and dry, so where is the corium?

  • so tepco and the physics forum (the fox news of pro-nuclear industry shills) say don’t worry about radiation so high it will kill you in 2 minutes, because it’s ‘contained’ within the vessel they’ve already admitted has holes melted through and is breeched

    don’t worry – tepco knows what they’re doing !

    “Why aren’t we seeing steam?”

    If the corium has melted through and is beneath the ground level, mud above the corium may be cooling the steam and absorbing some of the heat or much of it, when the pressure builds up enough steam pressure builds up causing a BURP through the muds from waters (past article spoke of mud/clay building up in pits) falling in behind the hole being burned by core, it may be enough for some or all of it to reach the surface of the pit to cause some steam becoming visible at times !

      The cooling waters mixed with mud will become more dense mud as the water is steamed off so mud/clay may be on top of the core and becoming harder from the heat that is being produced !

        Mud building up in the reactor was making it harder for them to get water on it, the same may be taking place down under, but when it does reach the water table and steam is created each drop will become @ 1700 times it size instantly…

    Can anyone explain why we keep getting CESIUM clouds in Northern CA since May 6? We used to get cesium clouds every 3rd week, with some days off in between, in March and April. But since beg of May, we have continuous orange clouds rolling over CA continuously. We had 2 days break last week when it rained, but they came right back last Friday. We need some time off to see blue sky again. What’s happening — why is it different in May? Is the fission increasing?

      The NILU (hidden) projections show the cesium concentrations ramping up-constant coverage of Western Coast. California is taking a wallop… and don’t expect any more full disclosure than you got from the sexy (or sex-crazed) Gov. Terminator.
      The more cesium clouds that you see also corresponds to the latest CA milk tests..:(

      Can you get photos and satelite ones that show such clouds

      Hey can anyone tell me whether California is one of the main growing areas for Asparagus? I’ve noticed that here in Auckland, NZ the local supermarkets, in my case Countdown in Quay St, have been putting large amounts of Asparagus from the USA on sale at less than half the normal price. And from what I remember our local Asparagus season starts around August so we haven’t started harvesting yet.

      So I’m wondering where this USA Asparagus is coming from and whether I should be weary of it if it’s come in recently?

        One of the largest world producers for Asparagus is Peru, which should be safe from radiation, anyway. Mexico has a big crop as well.
        What do you have to worry about in New Zealand? What kinds of veggies and fruits do you or do you not produce there???
        Thanks, in advance. :)

    Ok, so the fuel is outside the containment and in the dry well, how long will it now take before the fuel melts through to the ground below and we have a big boom?

    Or is it more likely that we will have an “elephant’s foot” situations like Chernobyl and this will all peter out (reaction-wise)

    Does anyone, anywhere have a clue?

    Just like TMI & Chernobyl the people in charge are scratching their heads.

      No. Nobody has a clue.

      This has never happened before. There are only conjectures and theories from here on out, until the facts from this situation are known, which apparently is not until several months after they occur.
