The energy generated by the natural breakdown of radioactive elements is immense and can be used in nuclear reactors. Australia has significant resources of both uranium and thorium within the rocks that make up the Australian continent.

  • 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.
