TEPCO redefines “cold shutdown” — Only bottom of pressure vessel has to be under 100 degrees celsius, not reactor-core coolant

Published: July 22nd, 2011 at 10:10 am ET


Plugging reactors no longer stated goal for Tepco, Japan Times, July 20, 2011:

[…] A cold shutdown is usually defined as bringing the temperature of the reactor-core coolants to below 100 degrees. But this has been redefined as bringing the temperature at the bottom of the pressure vessels to below 100 degrees and reducing the release of radioactive materials from the reactors […]

    As much as I DO believe all that, I just can’t “go there” presently. Yes I know all about it…but it’s already hard enough tackling the Nuclear Cheerleaders @ HP WITH FACTS about Japan. To step into THAT area, the attacks would really come out. That’s a NO GO imo, at least for me. Thanks anyway! 🙂

    • vitruvian

      Just some friendly advice…

      Why don’t you do some research on the owner(s) of HP, their background, and who they are affiliated with.

      Once you are truly enlightened I suspect you will no longer feel the need to waste your time there.

      (remember, not the names but rather their backgrounds)

  • Funny cause they just re-defined ‘murder’; In the same respects…

    Anyone else notice that?

  • arclight arclight

    corium must be lurking in the basement or foundations then cos they didnt mention about the corium…hmmmm!

  • Just an fyi…

    If the seattle data was ‘A ok’.
    The people hosting that data, would be able to disclose it publicly.

    The only reason to withhold it is the implication of its findings… (which must be intolerable); So much so, they would rather employ criminal omission on a global scale, than explain them selves to the tax paying citizens of their nations.

    Thats like getting pulled over. While appearing as if you were on drugs, at the same time: Your also attempting to assure the officer that theres no reason to search your car…

    So I feel its safe to say, Seattle is a post apocalyptic, nuclear nightmare.
    Anyone with me on that note?

      The San Juan islands are between Victoria, seattle and Vancouver so would probably have similar readings. They probably get less rain. Hope the resident Orca pods survive this mess.

  • Sickputer

    They are in la-la land as we know well. There is no getting close to those container vessels to fix the holes. Probably the holes the corium seeped out are the control rod holes anyway which was normal for those reactors…the boron rods were inserted from below on these BWRs.

    Because of massive radiation forget fixing them for ten years unless the three Blobs crawl out of the concrete pad areas and Blobs 1, 2, 3 leave their respective buildings. The cool thing is that then they could actually see the enemy! The bad thing is the Blobs will probably kill the Northern Hemisphere.

    The good thing for Kan is he said he won’t resign until the problems are resolved, The bad thing for Japan is he will collect about 120 more monthly paychecks to help his family buy imported food and water. *;-) Sucks huh? I would respect him more if he had led a coalition to nationalize Tepco. Should have been done after the second week of the crisis. Tepco can’t handle this problem and the Japanese government reminds me of their actions in WWII all over again. Squabbling and lying to themselves and the people of the world.

    I’m with you Tacoma,…Seattle, Alaska, Hawaii, and parts of B.C. seem like hotter spots than most-IMO. But, that is only based on little true numbers, wrong numbers, lies, and conjecture. But, the numbers that connectingdots came up with recently up in B.C. are equally concerning to me. Basically, anywhere rain fell got . California sure got it’s doses, to be sure. But I think Seattle did get it the worst.

    • alexa

      BC got hit really hard by radiation. People there should evacuate to Eastern Ontario, Quebec or Atlantic provinces. I am Toronto and did not feel much radiation the last month.

      • milk and cheese milk and cheese

        I’m in the Toronto area. I’ve had small nosebleeds since March–nothing unusual in low humidity–and a strong metallic taste in my mouth after eating organic vegetables from the neighbours’ garden. We won’t escape this, the prevailing winds brought the poison to Lake Ontario a few days after BC was hit. I am sick and tired of seeing all the projections end with BC and California, as if the rest of the continent did not matter.

    Are not the San Juan Islands up in the middle of the jetstream firehose blast too? Do we have any more numbers or readings that we can get our hands on?

    • Hi Jill,

      I think the readings look something like this now:

      Otherwise, the hot particle count is going to be the same as Seattle. You’ll likely get high spot readings in some places.

      Wondering if connectingdots1 could do a reading on his way back, but that might not be for another two or more weeks (he’s just crossing Alberta and headed East).

      Or, there must be at least one person there with a Geiger counter?

    BP disaster lies still exceed TEPCO lies
    when oil/tarballs were found the origin had to be proven to be from the spill and not natural seeps or passing ships.
    In Japan the radiation leaking is always assumed to be from one just place and not some other source.
    Japan still has a way to go before they reach the bottom and claim top prize for biggest assholes on the planet.

    Contrary to power company figures, cost of nuclear power generation highest: research July 24, 2011

    “Tohoku Electric Power Co. boasts nuclear power’s economic efficiency, while Hokkaido Electric Power Co (HEPCO) the stability of its cost. Each site comes with bar graphs indicating the cost of generating power through various power sources, and the figures are exactly the same regardless of the utility. For every kilowatt-hour of power generated, hydroelectricity is listed as costing 11. 9 yen, petroleum 10.7 yen, liquefied natural gas 6.2 yen, coal 5.7 yen, and nuclear 5.3 yen.

    In a section of its website responding to questions sent in by elementary school children, Chubu Electric Power Co. informs us that nuclear power “is the cheapest.” The media, including the Mainichi, have often cited the information provided to us by power companies.

    However, Kenichi Oshima, a professor of environmental economics and policy at Ritsumeikan University, has done some calculations and has reached a completely difference conclusion. Oshima says that the cost for a kilowatt-hour of electrical power between fiscal 1970 and fiscal 2007 was 10.68 yen for nuclear, 3.98 yen for hydroelectric, and 9.9 yen for thermal generation, with nuclear-generated power coming out as the most expensive. These calculations were even presented at a meeting of the government’s Atomic Energy Commission last September. So how does one explain these two different conclusions?”

    #Radiation in Fukushima City Order of Magnitude Higher Than Official Numbers?
    “U-drain at an elementary school 56.9 microsieverts/hour; Fukushima Prefectural Government building 20.8 microsieverts/hour, Fukushima Railroad Station 2.4 to 22.4 microsieverts/hour. “Hot spot” everywhere. The Doshisha researcher was surprised to see these numbers. Does Fukushima City residents know about this?
    I couldn’t find the official radiation number for the Fukushima Prefectural Government building. The radiation at the Fukushima City Hall, about 1 kilometer away, is 0.95 microsievert/hour as of July 23”

  • moonkai

    A must see ! Famous writer Hirose Takeshi and 90 other influential people are suing Edano, Hosono, Dr Yamashita, the whole TEPCO gang including Shimizu (he won’t get away with murder) and are calling (rightfully so) crimes against Japanese citizens ! The fight is ON !


    ‎”everybody is cooperating in killing our children. There is no apologies for this !!” I love that guy !! 😉
    I am so happy to hear this I am going to open a bottle of bubbly !! 😉 There is still hope for people to wake up!

    • arclight arclight

      Nice post moonkai! Have one for me!
      He says…. Prof. Yamashita took up the position of health advisor on th 20th march during this emergency period. On the 21st he began his radioactivity safety campaign. And in April was joined by Kenji Kamiya and Noburu Takamura. He says that these three guys were saying that up to 100 milisievert was no risk to human beings, which means that they have permitted children to become victims of radioactive pollution. Hence they are criticised by people all over the country., but I want to make it clear that this is a crime that they are doing! I have just recently heard in Fukushima that parents with high awareness, have been telling thier children not to eat any shitake mushrooms or bamboo sprouts, when the children got their lunch! They separated the mushrooms and bamboo sprouts as they had been told, but then their [teacher?] was yelling eat this!! And forced them to eat everything!
      This is now what I occouring in our countryand this is happening because of Yamashita. Because the ministry of education and science is backing this! Why do we allow this to happen?
      Everybody is cooperating to kill our children! There is no apology for this!

      Questions from audience
      “the newspapers and other menia are reporting about all different radioactive substances like caesium, but isn’t plutonium, the most dangerous substance in this scenario? Isn’t it the alpha waves like in depleted uranium ammunition used in Iraq, or in plutonium?”

      “ I am now more afraid of strontium than plutonium, since the quantity of strontium that had been in the reactor is supposed to have been the same as that of caesium! We must not assume that the strontium has not leaked; it has just not yet been detected.

      Enormous amounts of strontium must have flown into the ocean. The dilemma of the current situation is that we don’t know yet what is where? I do not know either! What I found out when I went to fukushima recently: the problem is that fish is distributed throughout japan! You can buy such fish in the south of Japan in Kyushu. People in western Japan are feeling safe because of the distance, but they are eating such fish. Honestly speaking, I have not sufficiently found out what is going on now. The actual reality is that awareness is very low and our desire for feeling safe is definitely very strong. This is the current situation.”

      any english translated stuff from this guy would definately be interesting! as much strontium as ceasium! not good, didnt realise that! peace

    • BreadAndButter BreadAndButter

      Moonkai, those are fantastic news. FINALLY a ray of hope in all this despair.
      Thanks & cheers!

  • moonkai

    Where is the Strontium … Plutonium … Tellurium 132 … Uranium etc … The truth will come soon ! Japanese all over the net are fighting back. The govt has spent millions of yens to monitor Twiter ! But the truth WILL come out … it wants to come out ! The war is raging and the people of Japan are gaining momemtum! We will win.


    Tellurium132 was detected in Aizu on 7/20/2011. Tellurium is produced from melted fuel rods,and its half life time is pretty short (3.2 days).It means, melted fuel rods are still “exposed” to “outside” and keeps emitting Tellurium into the atmosphere. And what else ?

      Moonkai – To answer you question, “And what else?” It’s a damned long list and yes, it’s all being emitted, every second, of every minute, of every hour, of every day since the melt down occured. It sucks to be any or all of us…..

        I am so happy today !! On top of that, in two days, a Japanese friend of mine and I are meeting to finalize the launch of the movement “EVACUATE FUKUSHIMA” … It involves lots people and journalists friends of mine from Bloomberg and NHK, Celebrities and all the most active association to save the children of Fukushima … even the communist party (no I am not a REDster) … we are going to stick our message so far down their throat, they’re gonna feel it is another episode of Bush choking on a pretzel! I am printing TShirts, throwing a huge charity (awareness)event with hundreds of people and before you know it, we will all march down the streets of Tokyo and all over Japan. I am making also a video. I would need someone’s help here on ENENEWS to gather a few datas if you guys have time. What I first need is short clips of all the events that have taken place at Daichi from May to July (steam/ vapors/ fire …without the fog …..lol). We must act now … the momentum is building! I am going to hit all the embassies in Tokyo and all the press people I know! I am even gonna involve the Yakuzas (the good ones)! It is going to be awesome. Then when I am finished, I am going to Barcelona and eat some taps ans drinking Sangria !

        • BreadAndButter BreadAndButter

          You are truly THE MAN, moonkai.
          I am very happy to witness all the progress you’re making over there. It must be hard for you, with your family already evacuated and all…and instead of just running away, you make the effort to organise events and make the best use of the contacts you have.
          I am really, honestly, deeply impressed.
          Please take loads of pictures / videos and post the links.
          Can I make a donation to get one of the t-shirts? I’m serious, i WANT to get my hands on a moonkai charity shirt.
          You can send it to me when you’re in Europe, makes the shipping cheaper..LOL

            Thank you ! Well I have nothing to loose anymore … I lost everything ! So, now I am in a “I don’t give a shit” spirit, which I believe is the best feeling in the world … on top of that, the response for this week has been incredible! And that mean they want to fight back ! The little I can do, I will …then I have no choice but to leave! I have to take care of my own family.

            Step 1; ALert or confirm everyone’s fear in Fukushima through various associations and combined all the petitions outhere into one massive one to be delivered to the govt, Tepco and all the usual suspects as well as all the residents of Fukushima. (in charge my Japanese friend)

            Step 2; Raise quickly awareness and get help from the international communities, Embassies, CRIIAD, Greenpeace etc … They will ALL help! (I and other friends will be in charge of that that one)

            Step 3; Bringing the international community to protest with local Japanese in Tokyo …and maybe one day all over Japan ! (everyone)

            Step 4; Evacuating Tokyo … sadly I won’t be around for that one ! If I can, I will be gone long before that one

          • moonkai

            As for the TShirts, they will be cool looking ! 😉 V neck, dark grey with the obvious “EVACUATE FUKUSHIMA”… and I will send you one for free ! 😉

          Moonkai I have an idea for a montage to Fuku its like this a simple date and label of which reactor/SPF pool is exploding like picture of reactor 3 poppin off and just reactor 3 and date of explosion- But edit the explosions faster and faster then start adding the phase no danger stay calm! also articles with main ideas high lited like all 4 nuke reactors have PROBABLY melted thru their cores and now lay outside on the floors of the drywells….According to TEPCO then show date hit a big drum next article…..Show what freakin liars the Nukkers are by pointing to the dates that show other articles where they are gaining control and the dates they say this happened – the talk of reactor cooling when no reactors exist anymore!- The water release in the groundwater the sea and end with all the babies dying in Japan the states mex and CANADA- That should get the point across-

            I’ve been an avid cam watcher since the early days, before the Tepco time-lapses were available I made many myself from the NHK feed. I haven’t posted here for quite a while, but I’ve stayed tuned in. I create time-lapses as part of what I do for a living, I’ve always been fascinated with how one can see “big-picture” patterns and fluctuations when time is sped-up or slowed. In my opinion, the Tepco Cam time-lapses (if unaltered) are our best way to really SEE the actual situation at fukushima. Combined with the technical expertise of some of the other Enenews community members (and even some TEPCO data) we can make some pretty solid observations, theories, and conclusions about the real status of the reactors.

            For anyone who doesn’t watch the TepcoCam thread, I’d also like to highlight the wonderful, and extremely important observations Anne has made regarding correlations between earthquakes and vapor releases as viewed on the time-lapses. Looking up earthquake data and matching it to video is tedious work. Thank you for doing it. I thought Annes observations regarding local and shallow earthquake activity (a while ago) right below the plants were especially poignant.
