Which is why they use it as an outer layer in the classical fission fusion fission devices. I guess I need to look up the cross section for U238.

The question is also, so you generate more neutrons and you've done the last two stages of a thermonuclear weapon; aside from the novelty, what sort of interesting thing could one do. (Maybe I could get ahead of the half life in breeding Pu by using those secondary neuts).

One must have a worthy quest, after all...
