YELLOWCAKE (F.Y.I.)

NUCLEAR FUEL CYCLE * Mined uranium ore is purified and reconstituted into solid form known as yellowcake * Yellowcake is converted into a gas by heating it to about 64C (147F) * Gas is fed through centrifuges, where its isotopes separate and process is repeated until uranium is enriched * Low-level enriched uranium is used for nuclear fuel * Highly enriched uranium can be used in nuclear weapons
