  • that's next door to the Rents too High party meeting room?
    by FradyKat 3/27/2011 9:07:13 AM

  • lol Hank
    by FradyKat 3/27/2011 9:07:28 AM

  • No, that's two doors down. The Get The Fuck Off My Lawn You Damn Kids meeting room is in between.

  • So, does everyone else have the feeling that the water problem will continue to grow, making more of the site relatively inaccessible?
    by Hank Scorpio 3/27/2011 9:09:45 AM

  • @Hank Scorpio A valid point. I'm concerned about how much Iodine-134 they found in the water. It only has a half life of 55 minutes, so if nothing new was being produced it should have been virtually eliminated from the reactor at this point. Why so much?
    by borrrden 3/27/2011 9:13:15 AM

  • I noticed that as well. IIRC, its concentration was the highest between it, I-131 and C-137. I don't know the proportions created normally, but even lacking that knowledge, one would be safe in guessing it's not old contamination.
    by Hank Scorpio 3/27/2011 9:16:06 AM

  • I asked earlier about possibly introducing lead pellets into the water being injected to the cores. The hope in my mind is that it would fill the core, become molten, surround the the undamaged core and follow the damaged core to its resting place. What do you think?
    by Hank Scorpio 3/27/2011 9:18:10 AM

  • Well, perhaps not molten but certainly change from a solid to a liquid. The temperature would rise far enough once the water was displaced by enough lead.
    by Hank Scorpio 3/27/2011 9:19:04 AM

  • @Hank Scorpio You mean the end goal being a core completely full of molten lead?
    by borrrden 3/27/2011 9:19:55 AM

  • Liquid or molten depending upon the temperature reached.
    by Hank Scorpio 3/27/2011 9:20:36 AM

  • Has anyone else noticed that the Reactor temp is steadily rising in # 1 reactor ???
    by wtm 3/27/2011 9:21:07 AM

  • @Hank Scorpio I think that pumping solid lead pellets through their pumping system would risk damaging their pumps....
    by borrrden 3/27/2011 9:21:14 AM

  • It would have to be introduced upstream from the pump.
    by Hank Scorpio 3/27/2011 9:21:46 AM

  • But in theory, would that generally solve the issue to have a reactor filled with lead?
    by Hank Scorpio 3/27/2011 9:22:01 AM

  • @wtm - I've noticed that as well as very low pressures in 2 and 3.
    by Hank Scorpio 3/27/2011 9:22:13 AM

  • Is the water height that the JAIF reports show the water height compared to the top of the pool or to the top of the rods ??
    by wtm 3/27/2011 9:23:12 AM

  • The only water levels I saw in the report (I'm looking again) are in relation to the reactor cores. Those numbers are definitely measures from the top of the rods, or where they used to be.
    by Hank Scorpio 3/27/2011 9:25:09 AM

  • @Hank Scorpio I don't know the answer to that. I do know that they can't simply introduce things upstream from the pumps though. The reactor sustains high internal pressure, and any opening in the line would render the pumping ineffective. It was compared to trying to put water into a balloon that was already inflated.
    by borrrden 3/27/2011 9:27:13 AM

  • If I understand correctly though, they're injecting the water to the core via a feedline. The pump is outside of the reactor. Am I wrong?
    by Hank Scorpio 3/27/2011 9:28:41 AM

  • @Hank Scorpio Yes, but you can't compromise any of the line between the pump and the destination, or there will be a pressure leak.
    by borrrden 3/27/2011 9:29:28 AM

  • Preheat the water to liquify the lead before the pump?
    by Hank Scorpio 3/27/2011 9:30:32 AM

  • Morning all - any overnight news
    by fiona 3/27/2011 9:30:46 AM

  • @Hank Scorpio You would have to heat the water to over 300 C....so it wouldn't be water anymore would it? ;)
    by borrrden 3/27/2011 9:31:18 AM

  • Under a certain amount of pressure it would still be water, but I admit 300C would be tough.
    by Hank Scorpio 3/27/2011 9:32:11 AM

  • @fiona Check the NHK link at the very top, if you haven't seen it.
    by borrrden 3/27/2011 9:32:18 AM

  • @Hank Scorpio Yes quite tough indeed docs.engineeringtoolbox.com

    by borrrden via Docs.engineeringtoolbox 3/27/2011 9:33:35 AM

  • The hookup to the feedline doesn't allow backflow, right? Disengage the pumps, fill the line with lead pellets, reconnect the pump, shove 'em through. Rinse. Repeat?
    by Hank Scorpio 3/27/2011 9:33:41 AM

  • @Hank Scorpio Another problem is the reactors are absolutely huge, they would need so many lead pellets. Furthermore lead is very heavy and heaven forbid it clogs the line by mistake...... :(
    by borrrden 3/27/2011 9:36:29 AM

  • Hi everyone www.bbc.co.uk has an interesting article on the effects of radiation, a somewhat different view x
    by Kat 3/27/2011 9:36:47 AM

  • Yes, the clog possibility is a serious issue. I assume the only way would be to allow the core to heat up to around 300C before injecting. In fact, since lead is far heavier than water, I suppose the only way to get the lead into the core would be to liquify it before it got to the pump and make the injection consist entirely of lead. There aren't many pumps which can handle 300C water, let alone lead.
    by Hank Scorpio 3/27/2011 9:39:01 AM

  • Not core at 300C, RPV. Sorry.
    by Hank Scorpio 3/27/2011 9:39:55 AM

  • @Kat I am very happy to read this article. I would like to hear other scientists' opinions on it, because it seems to good to be true. Almost like radiation is not harmful at all....
    by borrrden 3/27/2011 9:45:59 AM

  • I agree Hank, developments of the last days show that it got bigger and bigger and to me it looks as if it could become more and more inaccessible.
