@all I've noticed that the steam is far worse when it's raining and/or foggy...whether during the day or not. Given the temps of SFPs I'm not surprised.

@LM That explanation for #3 sfp makes me nervous they have 4sfps all in a state why is 3 worse it just seems strange but to me everything is strange

@Elaine 3's SFP was badly damaged in the blast. I think between possible breaches in containers, corrosion from saltwater, debris, and heat 3's SFP is in a world of hurt. We can only hope there's really no MOX in it!

@elainekirk Personnally, I think the explanation that ph level is the reasoning behind adding the boric acid is bogus...MOX fuel assemblies would explain why #3 gets boric acid and the rest don't...still grinding through details that may offer circumstancial evidence

@lillymunster This is a kind of staggering number from that article on the flooding: "An astounding 195,000 cubic feet of water per second is expected to flow past Omaha today. Visualize the volume of water this way: Every second, 195,000 basketballs are cascading downstream."
by RadioGuy 6/27/2011 12:10:40 AM

@smoss That was my instant thought, too. Oh dear, they suddenly have to add lots of boron.

@Edano thats rather hopeful news I hope they make much noise France should know radiation doesnt respect borders

@all Unfortunately, this is what we're up against: "Nuclear material accountancy is not the same as nuclear material accounting. Nuclear material accounting is what a state does and what a facility operator does. It is really all the bookkeeping that is associated with measuring nuclear materials, establishing material balance areas, taking inventories and the like. Nuclear material accountancy is what the IAEA does, which includes everything that the state and facility does plus some magic - some heavy dose of politics that converts a lot of numbers into a political statement that "there is no evidence that there has been a diversion of nuclear materials in a given year in a particular state." So the difference between accounting and accountancy is this heavy dose of subjectivity, politics, magic and all sorts of things that really should not be in there - because we really need a more stringent system of international oversight of what a state actually does to verify that its own nuclear material inventories are intact." www.ieer.org

@all Interesting video...speaking to water de-contamination. Brief sea-side shot of NNP.

@smoss I think those piles of rocks are the temporary tsunami wall. First time I have seen it actually done.
by lillymunster 6/27/2011 12:27:33 AM

@smoss yes. The plant manager wanted to put it in but had to prove to TEPCO corporate why he should be allowed to do so. That was in one of the rare videos and interviews done at the plant. I think this was back in early May.

@lillymunster I posted a few over the past couple days the tide barrier is on this one www.tepco.co.jp

@edano have you got these ?
Do we have this doc goving reactor readings /charts etc for all the reactors from the time of the quake / tsunami www.tepco.co.jp

@elainekirk : yep, but you need a supertechi to read it.

@knaut You need a techi to answer that :) @Veenie and for many yrs more :(
by elainekirk 6/27/2011 1:31:38 AM

@knaut Possibly. It depends on the levels of plutonium. Some amount of plutonium is produced as a by product of running uranium fuel in a reactor. We are sure they were running MOX in reactor 3. The fuel loading is well documented.
by lillymunster 6/27/2011 1:35:16 AM

@knaut : no, normal uranium fuel decays to plutonium as well.
by Edano 6/27/2011 1:35:19 AM

@elainekirk The thing is, that is from OUTSIDE the exclusion zone !
by Veenie 6/27/2011 1:43:58 AM

@Edano Wouldnt you be able to difference Mox from U fuel by looking at the levels of Pu isotopes present ? (Mod plz delete previous post, finger slipped)
by WolfDK 6/27/2011 1:48:11 AM

@WolfDK : you mean, difference fresh fuel ? yes. fresh uranium fuel has nearly no pu in it. if you mean if you can identify if pu stems from used mox fuel or uranium fuel, no, you cannot tell.
by Edano edited by Edano 6/27/2011 1:54:34 AM

@Edano I meant partly spend fuel, i could imagine that the ratio of Pu isotopes would be quite different, but i have not researched this.
by WolfDK 6/27/2011 1:59:10 AM

@WolfDK : i doubt it. pu238 decays to pu239, this decays to pu240 and then to pu241 in both cases. i don't think there are specific differences.
