Wonderful explanations here about Li7 breeding and what not. I would just like to add that D-T can be often seen as a stepping stone to a D-D reactor. D-T is easier, that's why its the immediate goal, but the next step on the path is D-D which doesn't have these problems.

I thought D-D fusion didn't generate enough energy to be worthwhile?

Ignoring side reactions DD spits out about 1/4 of the energy and has a smaller cross section. There's also a 50/50 chance that reaction spits out tritium instead of helium 3.

It's much harder to do than DT hence the focus on DT, but not impossible.
