should? this is TEPCO ;)

@radioguy LOL this is true. Are these the same as the plant parameters ?
by Nancy 5/28/2011 9:10:26 PM

for temps they're all different. what's a vessel frange, and an N4B

<Crippled nuke plant not prepared for heavy rain, wind
TOKYO (Kyodo) -- The crippled Fukushima No. 1 Nuclear Power Plant is not fully prepared for heavy rain and strong winds forecast due to a powerful typhoon moving Saturday toward disaster-affected areas of northeastern Japan, according to the plant's operator Tokyo Electric Power [........] A TEPCO official said, "We have made utmost efforts, but we have not completed covering the damaged reactor buildings. We apologize for the lack of significant measures against wind and rain."> mdn.mainichi.jp

@Nancy : i am fighting with the prressure readings plot right now. they have different units in core and drywell, it is a lot of calculation necessary to bring the numbers into a logical structurre.
by Edano 5/28/2011 9:11:40 PM

@Nancy it takes the latest TEPCO CSV readings post, and parses it into the googledocs spreadsheet, which reads ther on the page.
by radioguy 5/28/2011 9:11:53 PM

would be nice to have the penetration sizes in a standard BWR MARK1 bottom head... there are control rods,, safety rods, ,nuclear ionization chamber drives, probably some seal lines
by dean 5/28/2011 9:12:20 PM

@dean ...and you know from their vague specificity, they just told us where it started leaking in nice, CYA legal terms.
by radioguy 5/28/2011 9:13:45 PM

yes.. I am looking for penetration sizes
by dean 5/28/2011 9:16:11 PM

@UKVal I just read something similar from another news source. 3 and 4 are structurally challenged and have holes in them not to mention the storm surge I saw days ago was 38 feet?
by Nancy 5/28/2011 9:18:31 PM

@Nancy by 'storm surge' do you mean the tsunami or what was captured by the livecam some time ago?

<NEW YORK (Kyodo) -- A senior official of the U.S. nuclear regulatory agency said Thursday he had believed there was a "strong likelihood" of serious core damage and core melt in reactors at the Fukushima nuclear plant in the days after the March disaster in Japan.

"There were numerous indications of high radiation levels that can only come from damaged fuel at those kinds of levels, so we felt pretty confident that there was significant fuel damage at the site a few days into the event," said Bill Borchardt, executive director for operations of the U.S. Nuclear Regulatory Commission.

His agency also had "suspicions" about the spent fuel pool conditions, Borchardt told reporters after a speech at the Japan Society in New York.> mdn.mainichi.jp
by UKVal 5/28/2011 9:21:22 PM

@UKVal So of course he voiced his concerns to the press, right?
by radioguy 5/28/2011 9:22:52 PM

@UKVal On friday one of the media outlets said a 38 foot storm surge. Now Bloomberg is saying it weakened to a cat 3 and won't likely hit fuku? www.bloomberg.com
by Nancy 5/28/2011 9:23:04 PM

@radioguy naturally (not)!!!!
by UKVal 5/28/2011 9:23:16 PM

@Nancy I believe the stom has been downgraded -even so it remains pretty forceful - those latest pics of 3 suggest bits could slide off at any moment - ditto 4
by UKVal 5/28/2011 9:25:39 PM

@All- hello. where do we stand for Songda? what is current rating? Cat 3? Cat 1? Tropical storm??
by Meretisa 5/28/2011 9:27:00 PM

hi Mertisa
by dean 5/28/2011 9:28:25 PM

@dean hello. how are you today?? heard Songda will hit today or tomorrow at Fukushima??
by Meretisa 5/28/2011 9:29:04 PM

@UKVal If it hits with enough force I would worry about the tops of the walls on #4. I do not know how far along they are with the repair work on 4 to shore up the sfp. All that loose debris on 3 could get blown around if the winds are bad enough.
by Nancy 5/28/2011 9:29:14 PM

@Nancy I agree - makes me shudder to think about it!
by UKVal 5/28/2011 9:30:35 PM

@ all - just a reminder about my post pinned above...
by UKVal 5/28/2011 9:31:34 PM

those walls probably can't stand much wind loading by now
by dean 5/28/2011 9:32:02 PM

A so is Fuku still considered in the path it is hard to figure out from media reports, nobody wants to be anything but vague.
by Nancy 5/28/2011 9:33:04 PM

@dean yeah. I know. do we know what rating Songda has? is it lessening? will it be tropical storm or depression by then or no??
by Meretisa 5/28/2011 9:33:30 PM

I haven't been watching it in much detail meretise

by Majj 5/28/2011 9:40:13 PM

@Majj so I make that around 35-45% probability for Fuku - but it'll get pretty bad even if the projected course turns out right
by UKVal 5/28/2011 9:40:36 PM

@UKVal The water in Fukushima is cold . TS will will move more east I believe...
by Majj 5/28/2011 9:42:30 PM

Just like the US last year, protected by the jet stream .
by Ralph Unger 5/28/2011 9:43:29 PM

@Majj - hope so!
by UKVal 5/28/2011 9:44:54 PM

@dean can you give a quick explanation of 'bottom head penetration ' for this non techi please
by elainekirk 5/28/2011 9:45:20 PM

I find it curious that in the article below TEPCO seem to believe having covers on the reactors would help. Surely given the shape of the remains of 3 & 4 any covers would be blown off by a significant storm?
by UKVal 5/28/2011 9:47:16 PM

@all- have to go again. thanks and blessings to all. Be safe. HUGS
by Meretisa 5/28/2011 9:48:21 PM

They might cause another explosion, but out if sight is out of mind.
by Ralph Unger 5/28/2011 9:48:41 PM

@Meretisa HUGs to you too
by UKVal 5/28/2011 9:48:53 PM

you bet elaine... the pressure vessel bottom head has an area where several tubes accomodate such things as control rods, safety rods, instrumentation. the tubes are all part of the reactor vessel and extend down below the bottom head approximately 3-4 feet or so... at the bottom of these tubes are where the control rods are put up into the reactor.... so,,, all those tubes that go through the bottom head.. are calle...
