I have a degree in Nuclear Technology and I could explain the process in great detail, but really, this is stupid. Google the answer. You're just being lazy.
No, actually I'm missing some details but thanks for the effort.
Most thorium reactor designs aren't much different from conventional designs where the reactor is essentially a giant boiler that runs a steam turbine. The primary fuel is still Uranium (or in rare cases plutonium) and the Thorium merely increases the efficiency of the fuel burn.
