What Is the Best Nuclear Fuel? Understanding Uranium-235

Discover why Uranium-235 is the best nuclear fuel for commercial reactors and its role in energy production and safety considerations.

16 views

Uranium-235 is considered the best nuclear fuel for most commercial nuclear reactors. This isotope is preferred due to its high fissile properties, meaning it can sustain a chain reaction effectively. Natural uranium contains about 0.7% of Uranium-235, and through enrichment processes, this percentage can be increased, enhancing its efficiency as a fuel. Uranium-235 is used in both nuclear power plants for electricity generation and in nuclear weapons; however, handling and disposal require stringent safety measures.
