Mining lunar thorium for building nuclear rockets on

2017-9-24  Mining lunar thorium gains you nothing. Thorium is not fissile and cannot be used to fuel a nuclear rocket, power plant, or RTG. Designs for "Thorium" nuclear power plants use thorium as a fertile material to breed fissile U-233 using the neutrons from a fission reaction fueled by fissile U-235 or U-233.

Thorium - World Nuclear Association

Thorium is much more abundant in nature than uranium. Thorium can be used as a nuclear fuel through breeding to uranium-233 (U-233). When this thorium fuel cycle is used, much less plutonium and other transuranic elements are produced, compared with uranium fuel cycles. Several thorium-fuelled reactor concepts are under consideration.
