WebThorium 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. WebThorium averages 7.2 parts per million (ppm) in the earth's crust and is the 39th most abundant of the 78 crustal elements.
