The big fun-fun part of it is that it produces this unfriendly mix of Pl-139,140,141,etc. Aka Reactor-grade plutonium. Weapons grade plutonium is ==pure== Pl-139. You could hold it in your hand. The only way to get weapns-grade plutonium is to pump gob-boodles of Mwe (and millions of $) into a specially designed isotope seperation process. So, you get this nice hogde-podge of fissle material that gets used again and again and again untill all you've got left is some light to heavy metals in the half-life range of tens of years. Most of which are either alpha or beta emitters (ie tin foil is a great shield material).
Terrorists don't have the capital or the time to turn reactor-grade pl into weapons-grade. It's easier for them to buy pre-assembled warheads from the former Soviet republics of Kasakistan, Uzbekistan, etc. Those poor folks have nothing to eat. And nothing to sell but hiiigh priced oil and big boom-booms. What would you do? Starve?
