I was going to comment on your very good references, but I stumbled across this page, on a website you have mentioned. If someone wants to be shocked and appalled, all they need to do is read this web page.
It appears to be an official IAEA document, which has many details of Iraq's purchases of uranium, and how it was processed, and how much is missing. I particularly noted this minor purchase:
The yellowcake procured from Portugal was supplied in two batches. Batch 1, received on 20 June 1980, consisted of 429 drums containing 138,098 kg of yellowcake and batch two, received as three consignments over the period from 17 May 1982 through 20 June 1982, consisted of 487 drums containing 148,348 kg yellow cake.

(138,098 + 148,348) X 2.2 = 630,181 Pounds / 2000 = 3151+ TONS /20 = ~158 semi truck loads (standard 18 wheelers)
Over half a million pounds of Uranium, and that is just ONE buy. They also bought MUCH more, from other sources, including enriched uranium.
What does a country with thousands of oil wells need with all of that? Nothing good.
