  • Decay heat as a percentage of full power:
    After scram 6%
    After 1 day 1%
    After 5 days 0.5%
    by Jim 5/8/2011 1:46:20 PM

  • So that's 0.5% of rated thermal power of the reactor.

  • @Jim - with an intact core and control rods, yes. But with 30-50% core damage...?

  • @es no I had not seen that, pretty cool. I expected more garbage in the SFP. Also not seeing any of the reactor parts that were supposedly inside. Anyone have any idea where the blog owner got the video from?

  • @hudebnik I said cooling is limited as it melts.
    by Jim 5/8/2011 1:49:04 PM

  • @Jim - absolutely! But could that account for a rise in RPV temp from about 100C on 1st May to 314C on 8th?
    by hudebnik 5/8/2011 1:51:10 PM

  • You get a large melted blob and it's harder to cool and temps go higher until all the water in the world doesn't do anything more because it's the heat TRANSFER that is limited.
    by Jim 5/8/2011 1:51:12 PM

  • @hudebnik I think so. What's half a per cent thermal of your favorite?
    by Jim 5/8/2011 1:52:21 PM

  • So any word at all on #1 progress or the epic steam show they did about 8 hours ago? I tried to get METI plant statistics for the 7th or 8th, I found one but it is blank. Still no word on yesterday's smoke show either?
    by Nancy 5/8/2011 1:53:17 PM

  • I saw quite a bit last night about the fire in #3. No official comment.
    by Jim 5/8/2011 1:55:20 PM

  • @Nancy I missed an epic steam show? Oh well, gotta sleep sometime. R1?
    by radioguy 5/8/2011 1:56:07 PM

  • A report said 'outside' of 3. Don't know what could burn on the outside.
    by Jim 5/8/2011 1:56:24 PM

  • @Nancy There is this that was posted on the other page.........I cant make any sense out of it except it was opened at 8pm I think translate.google.com
    by Angie 5/8/2011 1:58:25 PM

  • @Jim - well if it is dissipating 'only' 0.5% then that would be about 4MW to dissipate, a lot of heat in a restricted space if there is little or no coolant.
    by hudebnik 5/8/2011 1:59:45 PM

  • @hudebnik Exactly my point, only 4 million watts, 4 mil J/s, 40 000 light bulbs, etc. Plenty enough to heat things up if your heat transfer is compromised. So anyway, I think were past any discussions about boron.
    by Jim 5/8/2011 2:03:53 PM

  • @Angie thanks, at least we know they did open the doors
    by Nancy 5/8/2011 2:07:59 PM

  • @Jim - I'm sure you are right. Wasn't there a warning from somebody in the GOJ a couple of days ago about being TEPCO needing to be specially careful about the temperature of #3? I vaguely remember it but can't find it.
    by hudebnik 5/8/2011 2:08:14 PM

  • @radioguy about 10pm CST right after the discussion on Jim's server ended. It was to the left of 1, looked like it was pumping out smoke or steam
    by Nancy 5/8/2011 2:09:18 PM

  • @Jim what did you see about 3? Posts online wondering what was up? Something more concrete?
    by Nancy 5/8/2011 2:09:53 PM

  • @Nancy The temp is meantto be 314c

  • @Nancy idk, think I'll go see if I can locate any news today. I saw tippy is smouldering...I started a ticker on my web site for cams, if anybody has a fav link, you can go type it in. the usual/tippy.html
    by Jim 5/8/2011 2:13:26 PM

  • @xxx posted it a earlier.
    by Angie 5/8/2011 2:14:35 PM

  • Univ. of Wisconsin has not had their feed for google earth up in two days?
    by Jim 5/8/2011 2:15:01 PM

  • @Angie thanks, I saw that. What I was looking for was the multi page report from METI that has the visual of the reactor with all the pressure and temps. The one Markfm usually posts. That report has not come out for 2 days.

    The Fukushima Daiichi nuclear power plant accident. In Unit 3 has raised the temperature of the reactor, and that does not contain enough water for the damage to the cooling pipe, a portion of the fuel burn-through, the heat came from there, perhaps because a found in an interview that government officials are.

    The temperature of the Unit 3 reactor pressure vessel 08 at 5:00 am and 151.9 degrees upward trend becoming restless, but has increased compared to nearly 40 degrees a week ago.

    According to officials, the cause of the temperature rise is not in good enough for the water damaged some water pipes are sent to the reactor, and even some fuel rods melted fall down, it is considered likely that the heat emitting.

    Toukyoudenryoku for injection into the reactor, even this weekend, will switch to another pipe plumbing system currently being used.

    Meanwhile, now that the Unit 1 reactor building doors open at 8:00 pm on September 8. At this time, but will be released from the small amount of radioactive material, "exhaust blower" that level is down by NISA impact on the surrounding environment is "no obstacle" judges for permission.

    The door opened, people have become to be able to work inside the reactor building, Unit 1 will be able to progress toward a stable cooling. (08 16:56) --Google translate from news.tbs.co.jp

  • good morning fukushima

  • @dean hi! what's up? Besides reactor core temp?
    by Jim 5/8/2011 2:32:52 PM

  • the price of rice..
    by dean 5/8/2011 2:33:22 PM

  • @dean I don't know how most people can afford to get to work! I filled my car up yesterday and got half a tank.
    by Jim 5/8/2011 2:35:08 PM

  • @Jim do you have a link to the page on TBS with that text? The link went to the mainpage
    by Nancy 5/8/2011 2:35:20 PM

  • @Nancy Oh, I guess I followed a translated link. sorry
    by Jim 5/8/2011 2:36:34 PM

  • @dean "I'm sorry, Mr. Boss, I just can't afford to work for you anymore, unless you can move your office next door to my house,"

  • @Jim Thanks! that is about the only useful news from the media this weekend..
    by Nancy 5/8/2011 2:51:06 PM

  • @dean Need good heat exchangers.
