Well, since you seem to have some experience in these matters, here's a link to the full story: US-Russia Team Seizes Uranium at Bulgaria Plant. From the article: 37 lbs, 36% enriched.

Doesn't seem like bomb material to me. Perfect terrorist material, though. Everyone has been brought up to believe that any amount of radiation is lethal, so you blow this stuff in an a standard explosion in the middle of Manhattan and people will be afraid to go there for years.

Thanks.

Agreed. If this is to be used in a bomb, it'd be the oft-referenced "dirty bomb" like you mentioned.

Dispersion of the caliber you mention would require an elevated detonation for maximum yield.

Dear God...what a horrible thing all of this is to ponder.
