Despite its name, yellowcake can vary in proportion and color from yellow to orange to dark green blackish depending on the temperature at which the material is dried this affects the level of hydration and impurities , with higher drying temperatures producing a darker and less soluble material.

Inhalation or ingestion of the Yellowcake dust particles may be harmful. Valerie Plame also engaged in her own lie campaign by spreading the notion that the Bush administration outed her as a CIA agent.

Curry says the president kept mum about the discovery in order to keep terrorists in the dark. Next Up. We have been hearing from the far-left for more than five years how, Bush lied.

The material is called yellowcake because a drum of the powder produced by early uranium mining operations resembled a yellow cake.

How uranium ore is made into nuclear fuel - World Nuclear Association

Yellowcake is used in the preparation of uranium fuel for nuclear reactors , for which it is smelted into purified UO 2 for use in fuel rods for pressurized heavy-water reactors and other systems that use natural unenriched uranium. Essentially from the early s to the mid s South Africa was shipping yellowcake uranium to Israel but the Israelis were not allowed to use it for military purposes because they had agreed on bilateral safeguards.

The enrichment process needs to have the uranium in gaseous form, so on the way from the mine it goes through a conversion plant which turns the uranium oxide into uranium hexafluoride.

Initially, the compounds formed in yellowcakes were not identified; in , the U. The slurry is leached with sulphuric acid to dissolve the uranium oxides, leaving the remaining rock and other minerals undissolved, as mine tailings.
