@lillymunster gosh you are so fast
by Elaine Kirk 6/29/2011 9:23:56 PM

@Peter.. in that vintage of reactor it wouldn't surprise me.. only the biological shielding areas and maybe some room walls would be the high density...
by dean 6/29/2011 9:24:30 PM

they weren't thinking of fuel melting anything back then..
by dean 6/29/2011 9:24:43 PM

@dean in the US proposed security document I read they claimed it was an additional security layer where someone would have to deal with the pool to access the rods. There was also a mention of the water providing some shielding for workers. It sounded like the plutonium was the big concern of workers coming in contact with it.
by lillymunster 6/29/2011 9:24:52 PM

they knew it could I mean.. but so highly unlikely
by dean 6/29/2011 9:24:58 PM

the plutonium would be hot.. emitting some radiation levels
by dean 6/29/2011 9:25:59 PM

@Elaine Kirk I read the sections on fuel and material processing and reactor unit inspections then did a search using "mox". Whatever program they used to create that online document is very nice and well done. The search tool works well.
by lillymunster 6/29/2011 9:26:09 PM

@dean, in the diagrams in schemes of the Mark I containments it looks that way. The thick part is the block on which the RPV is mounted on its skirt.
by Peter Melzer 6/29/2011 9:26:22 PM

@Peter Melzer grease of course ! we have leaks, theyre multiplying, and tepcos losing control, for the lies they are telling....
by Elaine Kirk 6/29/2011 9:26:38 PM

I agree Peter
by dean 6/29/2011 9:26:49 PM

@elaine.. I have it.. it's called gobblty gooop...
by dean 6/29/2011 9:27:14 PM

@lillymunster erm ...I couldnt find the search function lol...I had done a google search of the jnes site for 'daiichi mox' and it fetched the '05 doc up and I used the url to find '09 & '10

rpd.oxfordjournals.org protection potential of MOX-fuel doped with 231Pa and Cs radioisotopes
by dean 6/29/2011 9:29:11 PM

MOX fuel has a proliferation factor
by dean 6/29/2011 9:29:31 PM

@dean proliferation as in giving off radiation or proliferation as in international weapons terminology?
by lillymunster 6/29/2011 9:32:09 PM

proliferation as in plutonium getting into the wrong hands
by dean 6/29/2011 9:33:01 PM

if they can make it self protecting then anyone trying to get hold of it would receive a high does and die... .thus the SFP... no terrorist would probably go diving in there to get a mox element out
by dean 6/29/2011 9:33:44 PM

@dean the US document I read focused heavily on that concept. Anyone having access had to do so in groups, keys for the cranes, multiple security cameras and 24-7 armed guards. I could not help thinking if this is such a security issue why are we letting private companies handle it?
by lillymunster 6/29/2011 9:34:32 PM

@dean I think you have a plot for a new movie.
by lillymunster 6/29/2011 9:35:22 PM

by dean 6/29/2011 9:35:42 PM

; ) .. now your thinking lilly ...
by dean 6/29/2011 9:36:13 PM

@lillymunster to be fair goj did ask very nicely if tepco would hire security but tepco said no cos if would cost money and goj couldnt push it or they may have sacked the nisa bosses daughter

The plutonium economy

Plutonium, in the form of plutonium-dioxide, is mixed with uranium-diode to produce a mixed-oxide fuel, called MOX, which is used in a number of ordinary (light-water) reactors. The commercial use of FBRs, and the increasing use of MOX fuel, will involve the use of a large amount of plutonium. We will then be in what is known as the plutonium economy.

If the world is using, for example, 3,000 GW of nuclear electricity in 2075, and if this was based on the once-through nuclear cycle using light-water reactors (the current types), it will be generating approximately 600 tonnes of plutonium annually. But, if this nuclear capacity is provided by FBRs, as the nuclear industry predicts, more than 4,000 tonnes of plutonium will have to be fabricated into fresh reactor fuel each year (10). This is enough plutonium to produce no less than a million nuclear weapons!

Any country operating FBRs will have relatively easy access to plutonium usable as the fissile material in the most efficient nuclear weapons and will have competent nuclear physicists and engineers who could design and fabricate them. Because they could produce a nuclear force in a short time – months rather than years – these countries are regarded as latent nuclear-weapon powers. It must be expected that some of them will take the political decision to become actual nuclear-weapon powers.

FBR = FAST BREEDER REACTORS
by dean 6/29/2011 9:40:00 PM

I trust that there are those who are keeping detailed track of the plutonium at FUKU,,,
by dean 6/29/2011 9:40:57 PM

There will also be a high risk that terrorists will acquire plutonium, fabricate a nuclear weapon and detonate it. The increasing use of MOX fuel significantly enhances this risk. Some current light-water reactors, in Belgium, France, Germany, India and Switzerland, already use MOX fuel elements in a fraction (normally about a third) of their cores. If a terrorist group acquires MOX fuel, it could relatively easily separate the plutonium dioxide from the uranium dioxide chemically, and use the plutonium to fabricate a nuclear weapon. THAT PARAGRAPH I left out of the link but here it is
by dean 6/29/2011 9:42:10 PM

@lilly.. you probably have this alread.. archive.greenpeace.org
by dean 6/29/2011 9:45:00 PM

@lilly did you see where they document all the problems with mox in other countries with mox and also fast breeder reactors and yet they blindly ambled on with mox and monju
by Elaine Kirk 6/29/2011 9:45:39 PM

was thinking.. imagine a ship carrying MOX fuel being hijacked...
by dean 6/29/2011 9:46:07 PM

@dean doesnt mox because it reacts at lower temps also take longer to stop and cool down

Enenews: Local ABC News: 10 mile evacuation around Ft. Calhoun nuke plant (VIDEO)
by Puc 6/29/2011 9:47:50 PM

@dean they always have tight security dean but events like search.japantimes.co.jp cant be predicted
by Elaine Kirk 6/29/2011 9:48:06 PM

The 4,600-ton Pacific Teal, carrying about 210 kg of MOX fuel, unloaded its cargo Monday in Fukushima. Docking of the ship, which arrived off Fukushima on Sept. 22, had been delayed due to adverse weather conditions. search.japantimes.co.jp
by Elaine Kirk 6/29/2011 9:49:11 PM

yes @ elaine
by dean 6/29/2011 9:51:20 PM

when I first was exposed to the MOX idea, in testing and early stages I didn't like the idea.
by dean 6/29/2011 9:52:20 PM

Local news station video from the enenews story. According to the Lincoln NE tv station they DO have a 10 mile evacuation zone around the plant. First I have heard of this. www.youtube.com
by lillymunster 6/29/2011 9:53:07 PM

and,,, I don't like it today and wish it would stop today .. but probably won't
by dean 6/29/2011 9:53:10 PM

@dean
it is yet again an idea that business invested heavily in and they are not gonna let a little issue like safety get in the way of them recouping their money
by Elaine Kirk 6/29/2011 9:53:52 PM

@dean The Barnaby article mentions a 70 year supply of uranium so that is a finite material also, like oil.
by lillymunster 6/29/2011 9:54:02 PM

@lillymunster there is talk of water in the waste building too lilly

Los Alamos Fire: 1st Air Samples Show No Elevated Radiation Levels abcnews.go.com
The wildfire that surrounds the nuclear lab in Los Alamos, N.M., has grown to at least 61,000 acres amid mounting concerns about what might be in the smoke that's visible from space.

Such fear has prompted fire crews to set their own fires along the perimeter of the lab. So far, the strategy is working. The first air samples show lots of smoke, but no signs of elevated radiation.

"Those results show that what we see in this fire is exactly what we see in any fire across New Mexico," said Charles McMillan, the lab's director.
by RadioGuy 6/29/2011 9:54:53 PM

@ lilly.. things begin to happen when NRC initiates their incident response center.. that puts a whole lot of pressure on the utility to deal with a new player .... they would have to have bumped up their command center level at the plant
by dean 6/29/2011 9:55:43 PM

my big concern at this point for los alamos is, the smoke and ash getting into the suction ducts for HVAC units INCLUDING intakes for emergency diesel generators etc.. the plant where I was had to deal with things like that and those filters plug quickly... and have to be changed
by dean 6/29/2011 9:57:21 PM

So far the ABC station in Lincoln is the only one reporting an evacuation at Ft. Calhoun. It is already all over the rumor blogs... looking for some secondary confirmation.
