  • No way you read it all yet, I haven't even done that :-)

  • I guys I am here but I am not lol If you need anything just yell!
    by Angie 5/21/2011 6:27:01 AM

  • The more I learn , the more scared I become, there are so many ways that these plants can fail.

  • I trust my car will work but it does not include "Creep rupture modeling" in it's owners manual.

  • I just finished a highlight of it... very detailed Ralph.. nice find..

  • hi Angie..
    by dean 5/21/2011 6:32:52 AM

  • TY Dean, I got the link from UCS.
    by Ralph Unger 5/21/2011 6:32:56 AM

  • @Ralph I like to go over the report pretty fast and look normally at assumptions then conclusions and then dig in ..
    by dean 5/21/2011 6:33:22 AM

  • one thing I always look for in an analsis are the assumptions for conditions etc.. that sure changes things as the model goes on. I've found mistakes in engineers assumptions on simple things like not going to field to verify the height of instrument transmitters etc.
    by dean 5/21/2011 6:35:10 AM

  • I used to do automation, the biggest part of the problem was always telling the machines what was really happening, ...instrumentation.
    by Ralph Unger 5/21/2011 6:36:58 AM

  • Dust, heat, all can mess with instruments.
    by Ralph Unger 5/21/2011 6:37:31 AM

  • Nancy is goingt post what I did on the web site.. .and... I've sent it off to see what Arnie Gundersen has to say.. some recent observations are that the melt occured earlier and, TEPCO admitted that one of the operators apparently shut off the emergency core cooling system early with thoughts it may hurt the core
    by dean 5/21/2011 6:39:31 AM

  • 2000 degree blob of fuel and god knows what, might make a mess of the measurements.So SPEEDI was useless and the plant operators had not a clue as to what was happening.
    by Ralph Unger 5/21/2011 6:40:01 AM

  • Do not forget that venting was delayed because the PM was visiting at the time.
    by Ralph Unger 5/21/2011 6:41:01 AM

  • that is my thoughts... aswell
    by dean 5/21/2011 6:41:08 AM

  • yeh .. isn't that something
    by dean 5/21/2011 6:41:24 AM

  • houseoffoust.com see if this works Ralph
    by dean 5/21/2011 6:42:08 AM

  • Most people here are focused on current events, it is the old events that made this disaster.
    by Ralph Unger 5/21/2011 6:42:12 AM

  • Link is good, reading it ...
    by Ralph Unger 5/21/2011 6:43:05 AM

  • Nice writeup Dean, you should add references though.
    by Ralph Unger 5/21/2011 6:47:34 AM

  • Nancy and I have been emailing back and forth and they will be added.
    by dean 5/21/2011 6:49:40 AM

  • ty Ralph
    by dean 5/21/2011 6:49:45 AM

  • I will be happy to help in that as I have a lot of sources. Ok :-)
    by Ralph Unger 5/21/2011 6:50:03 AM

  • sure... I haven't tried it yet but there is a space to provide inputs.. the original document I started reviewing and then trying to break down was the station black out due to cable fires at browns ferry reactor and then I branched out from there
    by dean 5/21/2011 6:51:56 AM

  • I would lose the slashes and use English instead, but that is a matter of English and not content.
    by Ralph Unger 5/21/2011 6:53:02 AM

  • AKA did/could , and I am being very critical when I say that.
    by Ralph Unger 5/21/2011 6:53:57 AM

  • Nice work! :-)
    by Ralph Unger 5/21/2011 6:54:59 AM

  • well taken
    by dean 5/21/2011 6:56:25 AM

  • today I did some research for nancy on cooling vests or cooling systems like the vortex coolng systems vest so Nancy could forward on to help figure out something for the workers .. who.. are really feeling fatigue with all the anti-c's
    by dean 5/21/2011 6:57:43 AM

  • Like my wetsuit idea?
    by Ralph Unger 5/21/2011 6:58:16 AM

  • Cheap and handy and water is a great neutron absorber.
    by Ralph Unger 5/21/2011 6:58:45 AM

  • And it evaporates and keeps the workers cool.
    by Ralph Unger 5/21/2011 6:59:21 AM

  • yes
    by dean 5/21/2011 7:00:46 AM

  • it's after 1 a.m. here and I need to wake early .. nice talking Ralph.. and Angie.. good night for now...
    by dean 5/21/2011 7:01:23 AM

  • An old post of mine from TOD, www.theoildrum.com from April 2
    by Ralph Unger 5/21/2011 7:02:54 AM

  • @dean Night Dean!
    by Angie 5/21/2011 7:03:46 AM

  • Morning @all! An interesting perspective on how much money Tepco is spending to try to control Fukushima from Asahi Shimbun: "Tokyo Electric Power Co. recorded a consolidated net loss of 1.2473 trillion yen ($15.28 billion) in fiscal 2010 ending in March this year, officials said May 20.
    The ocean of red ink is mainly attributable to costs incurred in dealing with the disaster at the crippled Fukushima No. 1 nuclear power plant.
    An extraordinary loss of 1.0776 trillion yen will be posted in the annual financial statement for fiscal 2010. Extraordinary losses are from unexpected one-time events such as natural disasters.
    TEPCO President Masataka Shimizu, 66, plans to resign to take responsibility for the utility's handling of the accident.
    He will be replaced by Toshio Nishizawa, 60, at TEPCO's shareholder meeting to be held around the end of June.
    Initially it was believed the losses would be between 700 billion yen and 800 billion yen. However, confirmation of meltdowns at the No. 1, No. 2 and No. 3 reactors has substantially increased decommissioning costs."
    www.asahi.com Interesting too how Asahi quotes confirmation of meltdowns at all 3 reactors.

  • @hudebnik Morning to you! thank you for some news its been far too quiet here today!

  • "Mega float" arrives at Fukushima nuclear plant
    A giant barge has arrived at the Fukushima Daiichi nuclear power plant for use as a facility to store a growing amount of radioactive water.
    The steel barge, 136 meters long and 46 meters wide, can store up to 10,000 tons of water. It has been provided to Tokyo Electric Power Company from Shizuoka City in central Japan, where it had been used as a fishing park.
    The barge entered the nuclear plant's port on Saturday.
    At the plant, the amount of relatively low-level radioactive water keeps increasing as efforts to cool the reactors continue. Rain also falls on ground containing radioactive substances that were scattered by explosions following the March 11th disaster.
    TEPCO plans to store the radioactive water in the barge for a while. The situation is feared to worsen when the rainy season begins.
    The barge will be connected to pipes to transfer radioactive water from the nuclear plant.

  • An opinion piece in the Mainichi Daily News today -- "Death of nuclear plant worker highlights need for proper health management
    The death of a man in his 60s who was working at the waste disposal facility of the tsunami-hit Fukushima No. 1 Nuclear Power Plant has raised questions about the plant operator's health management of workers struggling to bring the nuclear crisis under control.
    Nearly 1,000 workers at the plant constantly face the risk of radiation exposure. Moreover, their working conditions are harsh because they are required to wear heavy protective gear. Many workers are exhausted and some have suffered heat stroke.
    If workers collapse, it will only prolong the work to stabilize the nuclear power station. Tokyo Electric Power Co. (TEPCO), which owns the plant, and its government regulators should do their utmost to ensure workers' safety and protect their health.
    (I've omitted a long section here, worth reading in full though) Article concludes: TEPCO and the government must not sacrifice workers' health by using the "emergency situation" as a pretext. They must do their utmost to protect the safety of the workers, whose working conditions will be even tougher in the hot summer months ahead.

  • There's a useful pull-together of what's known so far in the New Scientist www.newscientist.com A couple of days old but none the worse for that. Worth pinning for the moment?
    by hudebnik 5/21/2011 8:21:18 AM

  • Any mods on??
