[1] Thorium has been demonstrated to perform as a nuclear fuel in several reactor designs.
[2][3] It is present with a higher abundance than uranium in the crust of the earth.
Thorium resources have not been estimated and assessed with a higher level of confidence, as in the case of uranium.
Approximately 6 million tonnes of thorium have been estimated globally based on currently limited exploration and mainly on historical data.
[4][5] Thorium resources are found widely in over 35 countries all over the world.
