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.

      Typically a dirty bomb is used to scare or kill people off long enough that the area is abandoned but not so long that the attacker could not take over the area for their own use. Even if the attacker did not want to make use of the bombed area, and just wanted to deny it's use to anyone, something with a long half life is still undesirable. The longer the half life the more material the bomb would have to carry to irradiate a given area. With a half life of thousands of years there would have to be 100x more material than if a material with a half life of tens of years.

      A more practical dirty bomb would use something like cobalt, tritium, cesium, strontium, or polonium.

      Another problem with plutonium in a dirty bomb is that it's relatively inert chemically and very dense. Cleaning up plutonium would be almost trivial since it does not collect in the body, sinks like a stone in water, and only reacts with the most caustic of chemicals. Tritium would make drinking water and plant life radioactive for decades. Strontium likes to collect in the bones and irradiate people from the inside out.

    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.

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.
