Feb 16, 2012· Thorium is three times more abundant in nature than uranium. All but a trace of the world's thorium exists as the useful isotope, which means it does not require enrichment. Thoriumbased reactors are safer because the reaction can easily be stopped and because the operation does not have to take place under extreme pressures.

The Liquid Fluoride Thorium Reactor is a type of Molten Salt Reactor. Molten Salt Reactors are Generation IV nuclear fission reactors that use molten salt as either the primary reactor coolant or as the fuel itself; they trace their origin to a series of experiments directed by Alvin Weinberg at Oak Ridge National Laboratory in the '50s and '60s.

Uranium | Thorium Distribution | PMF IAS
Thorium232 is the most stable isotope of thorium and accounts for nearly all natural thorium, with the other five natural isotopes occurring only in traces. Thorium is estimated to be about three to four times more abundant than uranium in the Earth's crust, and is chiefly refined from monazite sands [Monazite contains % thorium][Monazite ...
