Why not thorium?

14-2-2012Thorium 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 Thorium-based reactors are safer because the reaction can easily be stopped and because the operation does not have to take place under extreme pressures Get price
