How Japan Lost Track of 640kg of Plutonium
Lasrick sends this quote from the Bulletin of the Atomic Scientists:
Most people would agree that keeping track of dangerous material is generally a good idea. So it may come as a surprise to some that the arrangements that are supposed to account for weapon-grade fissile materials—plutonium and highly enriched uranium—are sketchy at best. The most recent example involves several hundreds kilograms of plutonium that appear to have fallen through the cracks in various reporting arrangements. ... [A Japanese researcher discovered] that the public record of Japan’s plutonium holdings failed to account for about 640 kilograms of the material. The error made its way to the annual plutonium management report that Japan voluntarily submits to the International Atomic Energy Agency ... This episode may have been a simple clerical error, but it was yet another reminder of the troubling fact that we know very little about the amounts of fissile material that are circulating around the globe. The only reason the discrepancy was discovered in this case was the fact that Japan has been unusually transparent about its plutonium stocks. ... No other country does this.
This sounds bad: any slashdotter ought to realise, 640kg of plutonium ought to be enough for anyone.
SJW n. One who posts facts.
Let's not make a big deal out of this. 640kg of reactor-grade plutonium is only enough for a bit over 100 fission bombs / fusion bomb first stages, merely enough to make the recipient roughly tied for being the world's sixth most armed nuclear power.
Nothing to see here.
Fox: "I think we should call it... your grave!" Cast: "Curse your sudden but inevitable betrayal!"
From TFA: "No plutonium was actually lost, ... the material ended up in the wrong column on a spreadsheet."
That's because all Pu isn't created equal. It begins as some Pu in a used fuel element. It can be separated to become elemental Pu, which is somewhat dificult. The Japanese incorporate this into MOX fuel, from which it could easily be separated again (which would be pointless, but never mind). And then the MOX fuel is used, and the Pu (both old and new) becomes difficult to isolate again. This particular 640kg of Pu is in the form of an unused MOX core for a reactor which was scheduled to be started, but due to the hasty shutdown of all nuclear power in Japan after March 2011 never was. So the Pu in the unused core ended up in the books as a used MOX core.
Moreover, Podvig hints that this is about weapons grade material. It's not. Japan doesn't have a (working) fast breeder, no Hanford-style Pu production reactor, and no Magnox-style dual purpose reactors. This Pu is from light water reactors, therefore heavily irradiated, therefore isotopically a mess, and therefore not weapons-grade and never going to be weapons grade by any means. But Podvig makes a living off the case of nuclear non-proliferation, so of course desaster is looming, or he wouldn't have a job anymore.
That should keep him going for a while... At least long enough to get that damned Mr. Fusion fixed.
Sellafield in the UK lost nearly 30 kg of plutonium in 2005. But that was on paper only.....except the plutonium washed out to sea. Of course it can't enter the human food chain can it?
Maybe they lost it because the tracking system has the weight field set to Kg with integer data type?
After thousands of transactions the rounding error became 640Kg?
Let's wake up Godzilla!

http://www.vox.com/2014/7/8/5881737/forgotten-vials-of-smallpox-were-just-found-in-an-old-fda-storage-room
"Scientists find the strangest things when they're cleaning out old refrigerators. Like smallpox. "Employees at the NIH stumbled on six forgotten vials of smallpox" Last week, employees at the National Institutes of Health campus in Bethesda, Maryland were cleaning out an old storage room when they happened upon six glass vials of smallpox that had been packed up in a cardboard box, placed in a refrigerator, and then forgotten."
Plutonium? Hah. That is nothing compared to smallpox.
Sensationalize much?
From the Summary:
How Japan Lost Track of 640kg of Plutonium
From the Article:
No plutonium was actually lost
This was an accounting error, nothing more.
Usually memedot editors simply post the first paragraph of the original article as the summary, at least time they call out that it's a quote.
I want to delete my account but Slashdot doesn't allow it.
Whenever I lose something, I go back to wherever I last saw it and retrace my steps. Have they tried that?
Go to the Twin Pines mall in Hill Valley. I believe you'll find the missing plutonium in the possession of Dr. Emmett Brown.
Damn, they found my scheme! Now I will have to get plutonium for my diabolical plans elsewhere.

Buy the book BANNED by Costco!
Buy the book that Google can't seem to find in their search engine!
America!
http://www.dineshdsouza.com/news/
"Dinesh D’Souza, in response to the news of Costco removing his latest book, America: Imagine A World Without Her, from its shelves, made the following statement on July 8.
Today, I was stunned to learn that Costco had pulled my latest book, America: Imagine A World Without Her, from all of its stores. This was despite the fact that the book had sold very well at the chain and that my movie of the same name was releasing on over 1,000 screens the very next day. Today, I am disappointed to learn that this news has been confirmed by Costco. This action confirms the suspicions of all freedom-loving Americans and is a direct attack on my livelihood which I take very seriously.
In a free society, Costco is free to ban my book, but their customers are also free to shop at other stores which don’t censor books. In the book and the movie, I talk about the shaming of Americans and a culture of intimidation and censorship that has been spearheaded by the President himself. It’s one thing for Costco executives to pal around with President Obama and donate almost exclusively to Democrats. But to turn their company into a tool for suppressing dissent against the government is another matter.
I urge all Americans to watch our film in their nearest theater and buy the book from an establishment that honors freedom of speech. Once they do that, they will understand why the President and his allies are so afraid of this message and determined to keep it from reaching the American people."
Or is it actually true that you people are too lazy to read anything that is longer than a blog post?
They stored their plutonium stockpile carefully (also because packing it too tight is a very bad idea), but they were not aware that it was made of Pu-233. This explains why the stockpile they bought was sold at such a bargain price on the market...
Clean, safe and too cheap to meter.
Anybody who tries to use a misplaced 640 kilograms of plutonium to spread FUD about 1950's Energy Source of Future is just a damn liar.
But you have to admit, Japan has a pretty remarkable record with nukes. They must have it in their blood. At least the ones whose grandparents lived in Nagasaki.
Regarding the lost 1410 lbs of the deadliest substance on Earth, I'm pretty sure it has something to do with that giant lizard marching toward Tokyo (and no, I'm not referring to Shinzo Abe's economic policy).
You are welcome on my lawn.
I guess.
640 kilograms ought to be enough for anyone.
Which is about a US company losing "200 to 600" pounds of highly enriched uranium. This was discovered and investigated starting in 1965. Speculation has been that the uranium was diverted to Israel.
Source: Wikipedia, the source of all knowledge, some of it accurate.
The USA just found some vials of smallpox lying around

say oops in Japanese?
Reactor grade plutonium is useless for bombs, and parroting the lie doesn't change that. See Dr. Helen Caldicott: Toilet Paper & Plutonium at 5:50. (The other Caldicott videos by Thorium Remix also offer further insight into a prototypical leader of the anti-nuclear movement. The source of this story, "The Bulletin of the Atomic Scientists" belongs in the same class and deserves similar scorn for their rampant intellectual dishonesty.)
However, the article refers to unexposed MOX fuel, which is not the same thing, and the isotopically pure plutonium-239 can be separated in that case. The problem is that when Japan halted all of their reactors, the MOX fuel never made it into a reactor; had it been exposed in a reactor, there would be no issue. The safest place for fissile is in the core of a reactor, where it is rendered useless for weapons while producing vast amounts of energy. Molten salt reactors do an even better job and can thoroughly destroy all of the remaining spent fuel as well, which releases roughly 20 times more energy yet.

How could they miss that in their reports?
I mean, the smallpox was there, why not the plutonium?

This is hardly a new thing. Read "The Leaky Establishment" by David Langford
640 kilograms = 1,410 pounds
not everyone uses kilograms.
Not a surprise considering their incredible carelessness before!
Sounds like the kind of response I'd expect from a dumbs liberal.
"Hi, Japan here - country that waged war on you a few decades ago. We're so nice at reporting everything to you. BTW, we just lost almost a tonne nuclear weapons raw materials. Have a good day! Hello Kitty~~"
If anyone thinks Japan does not have assembled or semi-assembled A-bombs stored somewhere, such a person is very naive. That's where the missing plutonium went.
I am shocked, SHOCKED, that Slashdot would appear to support the paternalistic rights-management censorship attitude that "keeping track of dangerous material is generally a good idea."
Let's not make a big deal out of this. 640kg of reactor-grade plutonium is only enough for a bit over 100 fission bombs / fusion bomb first stages, merely enough to make the recipient roughly tied for being the world's sixth most armed nuclear power.
