From The Independent... Analysis: Saddam's arsenal: from chemical weapons to nuclear programme

This is what they think he has, anyway. And if we're going after him personally, he has no reason not to use it all. My guess is that he has one or two surprises yet, and I wouldn't be surprised if he does have at least a small nuke. And he will get one, eventually. All he really needs is the material; building a Hiroshima or Nagasaki type bomb one you have that is supposedly relatively easy. I don't know about delivery, but that might not be such a problem in an invasion where he could use one as basically a mine.
