External power supply cut at 2 Fukushima reactors, NHK, July 22, 2011:

Tokyo Electric Power Company says part of the external power supply has been cut at the Fukushima Daiichi nuclear plant due to a problem in the transmission lines […] cutting off electricity to the No. 3 and 4 reactors.

The operator was forced to suspend a system treating radioactive water. Another system cooling the No.3 reactor’s spent fuel storage pool was also shut down. […]

It said radiation levels around the plant show no major change, and claimed there was little risk of a leak occurring.

TEPCO is working to restore external power, as it tries to find out what caused the problem.

More information on the status of the cooling systems

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

The cooling system has experienced numerous problems from the 4-km-long series of hoses and the water treatment system and has been halted several times.

“The problem is that this system has to work without trouble” for the circulation cooling system to function properly and maintain the temperature at the bottom of the pressure vessels below 100 degrees, [Hisashi Ninokata, a professor of reactor engineering at Tokyo Institute of Technology] said.

He added it is risky to use the current circulation cooling system, saying a more compact version should be set up in the future.

Tepco said it plans to build and start operating a full-scale circulation cooling system within three years.

[Tsuyoshi Misawa, a professor of reactor physics at Kyoto University’s Research Reactor Institute] also pointed out that while the government and Tepco said the system has achieved stable cooling, it is still too early to describe the crippled reactors as “stable.”

    “Another system cooling the No.3 reactor’s spent fuel storage pool was also shut down”

    Do we still have reactor #3? Do we still have SFP#3? I thought it is long gone with the wind….The R3 building seems to have been blown to pieces. I am getting confused. Either I am getting too old, or TEPCO is wearing me down with their lies.

    • There is a convenient fiction that there is a spent fuel pool #3 and that a reactor core still exists as well in that unit.

      Based on what i’ve read and seen, I don’t believe either to be true.

      What I don’t understand is why Arnie does?

      • Sickputer

        The radiation is fierce at 3. That’s partially because it was MOX, but also a lot of the blown debris fell back down inside or or close in small very hot chunks. I think it did not blow most of the Unit 3 core in that megablast.

    • Sickputer

      Thermal imaging I saw after the March blast showed a big chunk of the Unit 3 core. The photos recently of the spent fuel pond for 3 showed one visible fuel assembly handle.

      Must be a typhoon complication I am guessing for the power. Too bad it didn’t happen much earlier in the day. They will have a long night.

    “no major threat of a leak”. The entire Fukushima Dai ichi plant is one big fucking leak!!! NHK and Tepco are up each other’s big, fat polyp forrested pre-cancerous radioactive buttholes.

  • Risabee can you look at the reactors and tell me whether you think this image looks “normal”

    http://www.tepco.co.jp/nu/f1-np/camera/index-j.html

    It seems like a yellow haze is accummulating around #1…

    • irradiated californian

      no it does not look that way. i have no idea what cam you are looking at, but the cam linked doesn’t look anything like how you described.

      • I provided the link.

        was your baby born?

        • irradiated californian

          no the missus is about 3 and 1/2 months pregnant. thank you for asking though, all is well here. 🙂

      • Sickputer

        Oh Unit 1 is definitely freaky yellow on the time lapse! *;-)

        http://www.youtube.com/fuku1live#p/u/6/Dh11Vczmj34

        However, I have seen that color before and I think we talked about them painting the side of the building to make it not look so frightening. It definitely does have a nasty Halloween glow, but hang on in the time lapse and you will see it is the sunset shining off that side as the camera gets ready to switch to the nighttime camera. I don’t think the Blob is ready to come outside just quite yet.

        • Not on the reactor building–above it.

          Now the yellow is gone and it is tinged pink immediately above the building…

          It is possible that it something funky with the camera or perhaps it is emissions being illuminated by a setting sun…

          romantic if not for being so deadly…

          • irradiated californian

            yeah it looks like its clouds you are mistaking as haze around the building.

  • Definitely not clouds but it is all gone now.

    Irradiated when you first started posting here you described your partner as about 6 months pregnant. Your baby would have been born by now….

    • irradiated californian

      no, i said my girlfriend was a few months pregnant. then, i proposed to her later. hehe, my life story here :D. she found out she was pregnant in april.

      • Sickputer

        Jeez man…didn’t I teach you anything? Never out your family to the Internet! There’s cannibals out there! You should have said you were a hobo living on some California island and you stole L. Lohan’s cellphone to make annoying anti-Tepco postings on enenews!

        Just yanking your chain! *;-) My first significant other reamed me out 20 years ago when I made one of the first transoceanic Internet voice calls to Australia on my PC and SO said I was going to get us killed talking to strangers! Hoo boy…SO may have been right, but SO is still kicking, just not with me.

  • “No major change” – so it’s still dire then, well according to TEPCO and as if anything TEPCO has to say is even slightly believable.

    At the moment they’re up there with News of the World / Sun / Other “News” Intl brands / in terms of truthfullness and transparency.

      do you run breakdown stats on your news articles so in a given week i could calculate theamount of attention being given to fukushima or calhoune for instsnce? especially amongst the “alternative sites”? could proove interesting reading…to have the results published weekly say….i bet admin would be interested too…also click rates etc…we need to be able to proove censorship if we claim it and numbers like these are useful!! thanks for your posts keep up the good work!

    Big Reactor 3 Page
    This guy has all the interpretation of the Unit 3 pictures here I don’t agree with everything he says, but he has some good insights, and certainly more information than TEPCO who just said the roof was blown off. Hell, nearly half the service floor was freakingly blown away and collapsed and guts spilled out of the northwest corner. He’s sure that some sort of explosion has blown away not only the concrete manhole covers, but also the yellow cap, and the metal pressure cooker cap, which means the whole dang melted pot of fuel is OPEN TO THE !$#@% AIR. Somebody just sent me a comment that he thinks he can recogize the big yellow doorknob shape of the cap against the rubble on the nw side, I can see something yellow from a closer shot, but somebody on site could certainly take a closer look. My god, they need the same people who figured out airliner crashes and the wtc collapse to take a real good look at this damage. It’s not random at all, the key is in the analysis, and it deserves better than crowd sourcing it’s getting now since tepco has said zip, nada, nothing on the exact nature of the damage or even released a decent floor plan of what the heck is on those floors.
    ——————————————
    More interesting stuff (same page as above):

    They take him for a tour, initially between #2 and #3. The Tepco employees with him are not allowed to step out of the vehicle, because they will max their radiation exposure limit. He is ok to step out as he only stays there for a short time. Also they are not stopping near #3 because the radiation is obviously too high.

    He makes a strong point that if there is another earthquake followed by a tsunami, that would mean “the end”. He says that Tepco is highly bureaucratic and he had to make a serious argument in order to convince them to focus on building a new “wall” to prevent this in case it happens. This process has now been approved and progressing rapidly.

    He could also see inside the buildings and while looking at the ramble he felt that steel structures were damaged so badly by the tsunami as if they were candies. His impression is clearly that the entire disaster is happening due to human error and bad handling, since the reactor structures were intact after the tsunami.

    He greatly admires the incredible morale and strength of the people working there, while he says their “eyes look different” than an ordinary person.

  • Video of Fukushima disaster:

    http://www.asianweek.com/2011/06/04/nuclear-nightmare-japan-in-crisis-fukushima-documentary/

    NY Daily News covered how Paula Zahn and producer Scott Weinberger Monday were upstate in Tomkins Cove, overlooking the Hudson, grabbing final shots for a documentary on the earthquake and tsunami that hit Japan. It aired on Discovery April 28 at 10 p.m. I only found it in May surfing on my Frontier/FIOS cable, and then looking it up. It’s the first pretty good summary of the nuclear incident. I had not seen the video of the helicopter flying over the site just after the tsunami hit, or the story of the Idaho software engineer who had shots of the hundreds workers evacuating the site before the water hit. There have been some new pictures and theories since then, but only in pieces on blogs and small news stories.

  • milk and cheese milk and cheese

    If they say there is ‘no major change’ we can be sure that a major change has occurred.

    I take everything TEPCO says and reverse it; that seems to give a more accurate picture of the situation.

  • milk and cheese milk and cheese

    Another lie: the situation is not ‘stable’. But Tepco’s pronouncement was carried all over the MSM, which means…it is believed?

  • odylan

    Tepco says no “major” change in radiation.

    Somebody at Tepco please define “major”. Clue: it’s the opposite of miniscule.

    Analyzing this doublespeak “no major change” means that there has actually been “a change” and that this change is upwards (otherwise they would used the word “reduction”). So there must have been an upward change that is not major – in other words it is one shade of definition below “major”. Considerable, significant, marked, noticeable … take your pick.

    If it had been “slight” they would have said “slight”.

    Here is an update

    TEPCO probes Fukushima blackout

    http://www3.nhk.or.jp/daily/english/22_32.html

    Tokyo Electric Power Company is investigating the cause of a sudden power failure at the Fukushima Daiichi nuclear plant. The blackout halted the cooling of a spent fuel pool for 5 hours.

    The trouble occurred at around 7:10 AM on Friday, when a circuit breaker malfunctioned on the power feed to the No. 3 and 4 reactors.

    The blackout halted equipment to cool the spent fuel pool for the No. 3 reactor.

    Cooling was restored around 5 hours later by means of an alternative power source.

    The utility says there has been no major change in the pool’s temperature of around 30 degrees Celsius.

    TEPCO says the incident did not cause any radiation leakage, as work to inject water and nitrogen into the reactors continued with the other power source.

    The blackout also halted systems to treat decontaminated water flooding the underground levels of plant buildings, but the company says these were restored at around 3:30 PM.

    The company says all facilities disabled by the incident have now been rebooted.

    The utility says that although it has installed several external power sources, their automatic switchover functions were not available. The company says it will improve the systems.

    A sudden surge in the external power supply is thought to be behind the failure. TEPCO says it is looking into the problem.

    • StPaulScout StPaulScout

      If the SFP 3 was without cooling for 5 hours and it didn’t move from 30c you have to think there is little to no spent fuel left in the pool. Or what is left of it. Prior to the accident if the pool had been without cooling for 5 hours it would have been close to boiling, or boiling. It would have most definately NOT been at and stayed at 30c…..

  • Got this from physicsforum:

    http://www.asahi.com/national/update…107220127.html

    A partial blackout started at 07:10 this morning after a breaker tripped in a switchboard. The water treatment facility, some of the reactor surveillance equipments, spent fuel pool cooling systems and other systems stopped suddenly. The water injection into reactor cores, based on another power source, is going on. The circuit breaker might have broken down.

    http://www.sanin-chuo.co.jp/newspack…yid=1114536015

    This morning’s blackout concerned the power supply to units 3 and 4, which is also supplying the water treatment system. Unit 3 spent fuel pool, the common fuel pool, and reactor surveillance equipments stopped. The power supply was recovered at 04:00 PM this afternoon. No sudden rise of temperature was observed at any pool.

    http://www.yomiuri.co.jp/science/new…OYT1T00795.htm

    Equipments were sequentially switched to backup power source(s), resulting into full recovery at around 03:30 PM. The blackout did not affect the plant safety.

    http://sankei.jp.msn.com/region/news…1580002-n1.htm

    As part of the work to double the power line to units 5 and 6, units 3 and 4 had been switched to the power supply for units 1 and 2. The breaker that tripped is located on the power line supplying units 3 and 4 from units 1 and 2. The blackout cause is either the power consumption from units 3 and 4 was too much, or the breaker failed. The expected temperature rise in SFP 3 was 0.3 °C/hour.

    The flow of information from Fukushima Daiichi is likely to decline from next week :

    press conferences by the joint government-TEPCO disaster task force, which from April 25 had in general been held every day, will from next week only be held once on Mondays and once on Thursdays.
