Japan Earthquake | Page 179

@Pedro Jesus I don't think it's worldwide, it's just naive to think that a company would not try to withhold bad information. For example in the Pu levels: in their press release they say it's possible it's from atomic testing (repeated by CNN news reporter), but in their PDF they clearly admit it's "their" Pu. And then there is the "magic" re-assessment of reactor 2 w/o any explanation whatsoever.

@dean, i never said that, but all depends on a few things, plutonium by its nature is heavy and will settle to the ground quite quick, if it was one blast then that plutonium will be mostly on the ground, or in the sea, bar what gets wipped up in the wind, but at the moment plutonium in these sorts of numbers is not the biggest worry, it is the the other 2 isotops that pose a bigger threat to the public of japan,

Just learned about my own local plutonium accident from the late 1950s... Rocky Flats en.wikipedia.org - I only knew it as 'Rocky Flats Wildlife Refuge'... Comforting...

I just came across this video of the plant taken 11/3/27

@Debra Beckham : in fact the reactor vessel in #1 lost its pressure before the tsunami.

@Jay77 There will be a Fukushima Nature Reserve, it's just a matter of how large.
by Jojo 3/28/2011 9:21:57 PM

@Jojo Something similar to the Chernobyl Nature Reserve I suspect !!!

@Tenzing LOL that video about MOX "Making a safer world for our children"
by Bobby1 3/28/2011 9:23:32 PM

People don't understand. Fukishima Reactor 3 has MOX as fuel. US and Europe use only upto 1/3 of rods as MOX per reactor. Japan use 50% in some and and are the only country to use 100% MOX. MOX has 5% weapons grade plutonium. In other words the plume at Chernobyl was spectacular. Fukishima's can be a virtual mist, or an almost invisible amount to cause even worse effects.

@dean please don't don the trifocals you may see me for the complete novice I am and then where would my cred be ? ooo just thought, I don't have any cred - carry on my man don the trifocals :)
by elainekirk 3/28/2011 9:25:19 PM

@Gordon They should call it Icarus Nature Reserve

Odd. Today is the anniversary of Three Mile Island. en.wikipedia.org
by Nancy 3/28/2011 9:26:57 PM

?O-O?... trifocals on ... DANG.. I think I see some plutonium
by dean 3/28/2011 9:26:57 PM

@Tenzing: AFAIK, only a fairly small percentage of the fuel in reactor 3 is MOX, would take a bit to dig up a source though, they were only recently licensed to use MOX there.
by sims 3/28/2011 9:27:08 PM

@Tenzing Reactor #3 is using MOX and low-enriched Uranium. Do you know what percentage of each?
by Pedro Jesus 3/28/2011 9:27:09 PM

wow nancy...
by dean 3/28/2011 9:27:20 PM

@Jojo I think that might be lost on them, or they might take it as praise! ... This would be hilarious if it weren't so deadly.
by Gordon 3/28/2011 9:27:35 PM

@Pedro Jesus 32 Rods of MOX
by RadioGuy 3/28/2011 9:27:44 PM

@OPTIM i have posted link of exposion several times about 5 pgs back, they were not always showing this angle... but take all known buildings/towers into scale to give a better perseption of the 1)height 2)force - look at core as the plume rises 3) as the debris comes back down you will see on the left side very visable debris .... it is still breaking up.... REMEBER size of what is on the screen vs. the builds/towers.. these have to be quite large to still be visable and still be breaking up
by fitter 3/28/2011 9:27:46 PM

@Pedro Jesus as I said the information in that comment is from the link www.youtube.com I forgot to use quotation marks, I apologize.
by Tenzing 3/28/2011 9:28:42 PM

fitter good point plus.. the flash of the blast... must have been a tremoundous load on the floor of that building and sent shock wave through out the area...
by dean 3/28/2011 9:28:58 PM

@dean Are the rods all of the same volume?
by Pedro Jesus 3/28/2011 9:29:18 PM

@Jojo Icarus...perfect.
by RadioGuy 3/28/2011 9:29:32 PM

@Gordon Wings melting because you get too close to the sun (a ball of nuclear reactions)...a bit close to home, eh? I just hope it turns out well, or at the very least not catastrophic. I really really do.
by Jojo 3/28/2011 9:29:35 PM

pretty much pedro, the way the fuel is dispersed in MOX versus UR would probably be different..
by dean 3/28/2011 9:29:50 PM

@Pedro Jesus There are 2 different size rods. I posted the story below
by NHK Listener 3/28/2011 9:30:48 PM

@Jay77 I grew up there 60's 70's. It was quite a debate. When they came up with the wildlife refuge, I said What!?, But, I still think it's kinda weird. My wife's Father worked there after he had worked at Oak Ridge. He met his wife at Oak Ridge, TN and they moved to Colorado. They didn't have any problems, but the kids did. He was pretty famous in science circles. Richard (Dick) Woodard.
by Jim Carver 3/28/2011 9:30:52 PM

According to TEPCO, #3 reactor has 518 fuel rods. If they're all the same size we can easily estimate the percentage of MOX fuel rods, then
by Pedro Jesus 3/28/2011 9:30:53 PM

I do hope that the international community of experts begins to play in to this accident and that the Japanese government is receptive ... somehow.. I feel we may not have seen all of the potential things from the reactors..

Did anyone find the wind records for the explosion days days to compare with their Pu sampling line? It might tell us what they considered to be the critical day.
by RadioGuy 3/28/2011 9:31:52 PM

@NHK Listener I missed that one. Could you retrieve that information and check which are which so we can do some maths based on all these facts?
by Pedro Jesus 3/28/2011 9:31:59 PM

have seen several reports that france was preparing to ship "new" fuel to japan, but the gov't request it not ship due to the "lack of security" do not know what plant it was meant for... but thier ports are barley operational and i think they are "tied up with other problems" at the moment
by fitter 3/28/2011 9:32:10 PM

@Matsuoko, I cannot read the values on the ordinate well. But the professor says that much. The reactor vessels are usually running at 7 MegaPascal. The earliest readings he could obtain for reactor 1 indicated 0.8 MegaPascal at 2:45 on Mar. 12, that is on the day after the quake. He clearly associates the drop in pressure to a loss of coolant in the reactor vessel, owing to ruptured pipes.
by Peter Melzer 3/28/2011 9:33:19 PM

fitter.. in the reports of those shipments that were sent back.. on of the ships that had some barrels of the mox fuel oxide fell or something and broke open and they basically had an emergency on their hands from that...
by dean 3/28/2011 9:33:28 PM

No nisa reports is disconcerting
by NHK Listener 3/28/2011 9:33:46 PM

that's what I think too PETER... A LOCA which began the fuel damage before the tsunami
by dean 3/28/2011 9:34:06 PM

I need to take a break.. be back in a bit...
by dean 3/28/2011 9:34:41 PM

@dean i don't know if you looked or listened to the #3 explosion.... but the noise was very loud and the camera equipment recording does not look that close..
by fitter 3/28/2011 9:35:12 PM

@Peter Melzer : yes but because of the earthquake. this means that the pipes ripped before the tsunami, so the plant did not withstand the earthquake (they were so proud of that).
by Matsuoko 3/28/2011 9:35:28 PM

@Peter Melzer: sorry, mistaken, please don't observe the post before.
by Matsuoko 3/28/2011 9:36:48 PM

does anyone know where I can find the current plant status parameters? Not JAIF, but the actual pressures and temp.s , etc. ?
