  Yellowcake - Wikipedia, the free encyclopedia
Yellowcake (also known as urania and uranic oxide) is concentrated uranium oxide, obtained through the milling of uranium ore.
Yellowcake is used in the preparation of fuel for nuclear reactors, where it is processed into purified uranium dioxide (UO) for use in fuel rods.
Yellowcake is unenriched uranium and cannot by itself be used for a nuclear weapon.

It is radioactive, forming a coarse powder which is insoluble in water and contain about 80% uranium oxide, and melts at approximately 2878°C. It is created by passing raw uranium ore through crushers and grinders to produce "pulped" ore. This is then bathed in sulphuric acid to leach out the uranium.

The term yellowcake forgery refers to falsified documents which appeared to depict an attempt by Iraq's Saddam Hussein regime to purchase yellowcake uranium from the country of Niger, in defiance of United Nations sanctions.
The reference to the Yellowcake documents in U.S. President George W. Bush's 2003 State of the Union speech (in which he made a case for war with Iraq) became the focus of the first important public criticism of the plan to invade Iraq.
Sismi had reported to the CIA on October 15, 2001, that Iraq had sought yellowcake in Niger, a report it also plied on British intelligence, creating an echo that the Niger forgeries themselves purported to amplify before they were exposed as a hoax.

Yellowcake is a part of the early stages of the nuclear fuel cycle - a process that Iran insists it only wants to master so it can generate electricity.
On August 8 Iran chose to end its freeze on the conversion of yellowcake to uranium hexafluoride gas (UF6) at a facility near the central city of Isfahan.
Yellowcake production and conversion is a precursor to the ultra-sensitive process of enrichment, which involves UF6 being spun through cascades of centrifuges to produce enriched uranium.

Yellowcake, or uranium oxide, could be used to build a nuclear weapon, although it would take tons of the substance refined with sophisticated technology to harvest enough uranium for a single bomb.
The yellowcake was uncovered Dec. 16 by Rotterdam-based scrap metal company Jewometaal, which had received it in a shipment of scrap metal from a dealer in Jordan.
He said the dealer was confident the yellowcake, which was contained in a small steel industrial container, came from Iraq.

 lgf: Yellowcake Discovered in Rotterdam
Experts said that around 2 pounds of yellowcake, the amount found, would not be useful for either a bomb or fuel.
Yellowcake was a descriptive term that was originally applied to natural ammonium diuranate (ADU) which was yellow and chunky - it came to be applied to most form of uranium ore concentrates (UOC) including a lot of natural uranium oxides (uranium tri-oxide (U03) and triuranium octoxide (U3O8)), plus ADU and ammonium uranyl carbonate (AUC).
The Tuwaitha site was partially looted in March/April 2003 and though most of the yellowcake on that site was recovered an amount of up 20kg may be unaccounted for (a bit difficult to tell as some of the material was mixed with dirt and it tends to absorb water on exposure to air).

Yellowcake is the product of the uranium extraction (milling) process; early production methods resulted in a bright yellow compound, hence the name yellowcake.
The material is a mixture of uranium oxides that can vary in proportion and in color from yellow to orange to dark green (flish) depending at which temperature the material was dried (level of hydration and impurities).
Yellowcake is commonly referred to as U3O8 and is assayed as pounds U3O8 equivalent.

Prather further points out that the process of getting several hundred pounds of U 235 out of yellowcake could not be hidden in a mobile van: “You need to be able to convert yellowcake into uranium hexafluoride -- a solid at room temperature.
Prime Minister, before seeking more 'yellowcake' from Niger -- or anywhere else -- Saddam would have had to order his nuclear scientists and engineers to somehow acquire tens of thousands of gas centrifuges that could be linked up in series so the UF6 could cascade through them.

Verification measures involved weighing, non-destructive assay and sampling and analysis from which it was concluded that all of the yellowcake received from Portugal was fully accounted for and remained intact, as shipped, except for the loss of about 40 kg from a drum damaged during Iraq's salvaging/concealment activities in 1991.
The plant, which was constructed by Iraq in the period July 1985 to July 1989, was based on the well-proven technology involving the dissolution of the input yellowcake in nitric acid followed by multi-stage solvent extraction, ammonium diursnate precipitation, its filtration and calcination to uranium trioxide, from which the UO2 was produced through hydrogen reduction.
It was necessary to prepare the plant to process either Niger or Portuguese yellowcake and, during December and early January 1991, there was sporadic operation to clean up waste and scrap and to prepare the process for a new feed material of different chemical form.

yellowcake is such a low grade of fissionable material that it must be enriched.
to summarize, that the usofamerikan press, the brit press, or any other press, ever supported the illusion that saddam's iraq could produce nuclear weapons from yellowcake is proof positive that the members of the press have either all been lobotomized or all have been employees of their respective governments.

A shipment of scrap steel believed to be from Iraq contains radioactive material known as yellowcake, according to a recycling company in the Netherlands.
The shipment was passed on from a Jordanian metal dealer who claims he was unaware it included uranium oxide, the Associated Press reported.

The material at Tuwaitha is also characterized as being “under IAEA seal and control.” The article states that only two tons of yellowcake remained at Al-Tuwaitha after Gulf War I.  This is simply incorrect, according to my own sources.  Either the AP, the IAEA, or both, are misrepresenting the facts.
And why didn’t the UN ship the yellowcake and the low-enriched uranium out of the country 12 years ago?  Wouldn’t the UN be interested in denying Saddam the nuclear raw materials, in case he decided to conduct enrichment by calutron at facilities such as Tarmiya and al-Fajar?
It appears the IAEA is not really interested in non-proliferation at all; otherwise this material would have long ago been safeguarded in another country.  Thankfully, this overdue evacuation of a dangerous stockpile has finally been started by the DOE, even if much more remains to be done.

His admission to investigating magistrates in Rome on Friday apparently confirms suggestions that - by commissioning "Giacomo" to procure and circulate documents - France was responsible for some of the information later used by Britain and the United States to promote the case for war with Iraq.
It isn't obvious that this is the correct interpretation; for now, suffice it to say that we haven't heard the last of this story, and whatever lies behind it is sure to be interesting.
In the meantime, as we have argued on a number of occasions, it is almost certainly true that Iraq was trying to buy uranium from Niger, and the administration was foolish to back off that statement in the President's State of the Union speech.
