Tokyo water looks completely safe at this moment.

all Beautiful Minds :) if they were loading or unloading fuel from the reactor or SFP at the time of the quake/tusnami how would that effect your whatever it is your doing with your Beautiful Minds right now. Hope I'm not disturbing you :)

Guess I'm onto the Times articles today, well it's Sunday, gotta read the 'Times', "Radiation’s Enduring Afterglow", www.nytimes.com

Marie, your study of the pressure history on No. 1 is important. Do you recall the design pressure, and its excursions above and below that?
by Sky 3/28/2011 2:11:06 AM

OK, that's the difference. The other Iodine readings were south of the plant.

ok, i got the measurings, i will take them to bed and sleep on them. tomorrow i shall be able to explain everything. ;) good night.

@Sky alas, i do not know. Dean would....any good fact-finders want to assist?
by marie rich 3/28/2011 2:12:54 AM

@Tensing: I'm thinking the same as you. Actually, I'm wondering if the place can withstand the seismic activity given its current condition and don't even want to imagine another tsunami.

@Matsuoka G'night! Dream us up some insight :)

NEWS ADVISORY: Iodine-131 1,150 times normal level found in sea north of nuke plant (10:59)

@Jojo Hey, at least they didn't do the "oops, we were only off by a few orders of magnitude in our calculation" think twice....yet

@Sky It wouldn't just be the pressure excursions - I think we might actually have to have accurate temperatures to do anything meaningful.
by pj 3/28/2011 2:15:46 AM

@Marie, I feel like I have seen that number somewhere in the past week but can't recall where. Have read so many documents my mind is a swirl --- you know the feeling, no doubt!
by Sky 3/28/2011 2:16:16 AM

@pj right, and also have to know how much water they are adding to it and whether any intentional venting is being done.
by Sky 3/28/2011 2:17:07 AM

@Sky Yup. Had anyone seen recent temperature data for the spent fuel pools?
by pj 3/28/2011 2:17:53 AM

did you see kyodo news story about xenon in s. korea?
by marie rich 3/28/2011 2:18:16 AM

@Sky The fella from CNIC was worried about #1 and the temperature of 300 C at the bottom of the pressure vessel. I have seen a lower temperature since, but who knows?

articles.latimes.com Xenon was detected in US on 18th.

by Jim Carver 3/28/2011 2:19:37 AM

I love how every story, whether it's in S.Korea or US, always ends in "The center said the level of the radioactive material poses no concern for health and environment." without saying what the levels are.

@marie it was a live cnn update which said that pressure in one of the reactors was increasing according to japanese officials and it had just come across the wire s an urgent update.
by ricky 3/28/2011 2:20:11 AM

@Sky, you just have to focus on some peaks, like, I cannot remember quite precisely, Tc-99m has got a peak at 0.7 MeV. So you check at that energy, then check again one half-life later. The peak should be halfway down, if there is Tc-99m. When looking at a decay chain, as the mother decays, you ought see the peaks of the daughters rise. So from repeated measures and comparing the spectra, you can infer a lot about what is in the soup. Metastabile radioisotopes are particularly helpful, because they decay producing a line peak which is easy to discriminate.
by Peter Melzer 3/28/2011 2:20:40 AM

@Jojo The point may not be in how much they are detecting, but where and when. There is value in tracking that at least, I think.
by Meretisa 3/28/2011 2:20:52 AM

Because someone mentioned "A Princess Bride" I will mention "Naked Gun" Nothing to see here, move along, nothing to see here.
by Ralph Unger 3/28/2011 2:21:27 AM

@Meretisa Absolutely, but there is no hard data for any of these releases. Only a pat on the head and a "don't worry, everything is fine".
by Jojo 3/28/2011 2:21:35 AM

@Jojo I realize that, but if they find Xenon in CA and later in Nevada and later in Colorado... you get an idea of what is going on... a very rough idea, but something.
by Meretisa 3/28/2011 2:22:34 AM

Isn't that a bit disconcerting to everyone that you never see the actual radiation levels outside Japan? At least I haven't, I'd love to be proven wrong.
by Jojo 3/28/2011 2:22:47 AM

Is anyone keeping a spreadsheet of all these readings that get released, even if there are problems with the data? be good to at least start centralizing data. Or does this already exist?
