> Thorium is more abundant than uranium I don't disagree. What I said is that uranium is __also__ abundant. > Thorium must not be enriched and it cannot be enriched like uranium You're right. I was trying to use language that people would generally understand. Mixing breeding and enriching. They are quite similar words, differing in protons. Enrich = changing isotope (adding/subtracting neutrons), breeding = changing atoms (adding/subtracting protons). I thought this would be fine, sorry. Yes, you are right. > The extraction of uranium 233 from thorium ... is a process orders of magnitude simpler You are oversimplifying things. There's plenty of "simple chemical separation processes" that are very expensive. And sure, you can get 233 from this and use it for weapons but you still want some other elements if you're going to build a weapon. There's a lot to this and acidburn would be the better person to explain all that nuance.
