In a 100kT bomb, you can make more than 95% of the energy fusion (a trigger only needs a few kilotons) and this produces 20 times more neutrons than fissioning plutonium. So you can make more plutonium than you use in each explosion, and have neutrons left over for more breeding. The neutrons are fast, but a moderator can be used as fluid, and Uranium in solution, to maximize neutron absorption by Uranium and gunk. This allows all the uranium in the world, and all the thorium to become triggers.

Granted, 10k years is better than 300, but even there one should think about how to transition to a truly long-term solution.
