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.
