Yes, making the bombs themselves seems to be easy. The difficulty comes from U232-contamination which decays into strong gamma emitters, making handling difficult. However, there seem to be paths for the production of pure U233 from chemically separated Pa233, which one might be doing anyways in a thorium reactor. That would mean a significantly higher proliferation risk, because one would get pure bomb fuel form the normal operations of the reactor. However, I don't know enough about how easy or likely that would be to judge.
But in all, you are right, I think. And maybe even more than right.
- acidburnNSA 7y agoI mean to say that making clean U-233 (with very little U-232 and daughters) is easy. Certainly assembling a bomb given pristene weapons material is particularly easy. I'm a reactor designer and study this kind of thing. It's really just a question of how fast you move your Th-232 through a neutron cloud. If you move it relatively quickly and then do your Pa separation you can get very nice U-233 from Thorium. The nice thing here about low-pressure fluid fuel reactors is that you can move material in and out fairly readily.
