According to wikipedia:
en.wikipedia.org...
Modern yellowcake typically contains 70 to 90 percent triuranium octoxide (U3O8) by weight. Other oxides such as uranium dioxide (UO2) and uranium trioxide (UO3) exist.
Yellowcake is used in the preparation of uranium fuel for nuclear reactors, for which it is smelted into purified UO2 for use in fuel rods for pressurized heavy-water reactors and other systems that use natural unenriched uranium.
Purified uranium metal (not the uranium oxide) can also be enriched in the isotope U-235. In this process, the uranium is combined with fluorine to form uranium hexafluoride gas (UF6). Next, that undergoes isotope separation through the process of gaseous diffusion, or in a gas centrifuge. This produces either: A. Somewhat enriched uranium containing about four percent U-235 that is suitable for use in large civilian electric-power reactors, or B. Highly-enriched uranium containing 90% or more U-235 that is suitable for use in compact nuclear reactors - usually used to power naval warships and submarines, or in nuclear weapons.
Yellowcake is produced by all countries in which uranium ore is mined.
Maybe not easy to make a nuke from this, but it's still radioactive and dangerous to make some kind of dirty bomb.
Here's some info about yellowcake that Saddam kept:

Even when not processed into nuclear weapons, it was dangerous in its own right, being radioactive. It could also be used in other methods of spreading radiation short of full nuclear bombs. The AP story explained the logistical nightmare of simply transporting it. It also cited the fear of it falling into the hands of insurgents. That is how dangerous it was when we were in control of it.
Saddam could have had an active program without having anything in production or deliverable at all. A weapon program is not a weapon; it is a program -- it means the potential for future weapons. This distinction seems to get lost way too often.
