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.

In case of silicon carbide, the thermal expansion factors of several polytypes do not differ considerably. The US space agency NASA has once already proved the possibility of such solution by connecting silicon carbide polytypes 3C and 6H into a new polytypical heterojunction. But this remained unfortunately the sole experiment.
