Coal at the present time is the most commonly used nuclear fuel.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (B)

Nuclear fuel is material that sustains a nuclear chain reaction. Coal, on the other hand, is a fossil fuel used in conventional power plants, where energy comes from chemical combustion, not nuclear fission. In civilian reactors, the typical fuel is uranium—usually low-enriched uranium with uranium-235—often formed into pellets inside fuel rods. Some reactors also use MOX fuel, which blends plutonium with uranium. Because uranium-based fuel powers the vast majority of nuclear reactors, coal is not the most commonly used nuclear fuel.
