Title: TEPCO faces another potentially broken temperature gauge at Fukushima Reactor 2
Source: Enformable
Date: Feb 23, 2012

The temperature of unit 2′s RPV bottom rose by 11.5°C in 24 hours reaching 47.8°C at 11:00 AM on Thursday, while the temperatures from the RPV supporting skirt have also risen nearly 10°C over the last 5 days. The temperature levels from the Safety Relief Valves and the feedwater nozzles have also been steadily increasing since February 19th.

    If I had a thermometer that read to +/- 20C and I quoted the temperatures in decimals of a degree like Tepco, I would have failed my Physics practical test.

    Anyway, not to worry, it's just the thermometers going faulty again.

      Yes, they are all faulty, that must be it … TEPCO is faulty also….

      How long will it be before more things go faulty ? Apparently some kids have faulty thyroids also, check out EX-SKF there's a story there …

      If that isn't the truth. With such tolerances no one would report in decimals.

      It is like walking of 99 yards of a football field
      and measuring the remaining distance to the goal
      line with a micrometer.

  • patb2009

    The precision is 4 places but the gauges are probaly +/- 2% of full scale

    • ageezerofgiza

      Tepco have stated that "due to the possible damage" the thermometers are only accurate to +/- 20C. I know it is unbelievable, but it is typical Tepco.

    yipeee! this means more lies a cummin…… don't like the reality? well make up a new one…. these tepco guys are totally new age!

    Graph of temp in reactor 2 past 100 days:

    • pure water


      • Sickputer

        And don't forget to check our old friend at Reactor 1, the failed instrument that shows the radiation level in Sieverts.

        That graph is going back up again after such a long decline….way up since February 21:

        The many months of peaks and valleys from 10 to 400 Sieverts finally fell the past two months and we thought the corium had moved way down or out of the gauge range. But something is bringing it back into play.

        Could it be Reactor 2 corium has moved laterally closer to Reactor 1? Ah speculation…the best we can do.

        I bet the Tepco boys have much better toys than they will admit in finding out where the big blobs have migrated.

      Hi B&B. They appear to have replaced a gauge on the 17th. A few days ago you posted a link like this, and the English version said "defective gauge" (which I mocked at the time). In now looks like it was true though.

      I guess the takeaway is that the temperature really may be inching up again.

      Is that your sense of it?

    You know I've begun to wonder with the live Fukucam and some of the anomalies that have been occurring that there might some venting they are doing after dark. Anyone know if they were venting through the stacks if it would be readily apparent?
