How Much Uranium-235 Is Needed for a Nuclear Reactor?
Discover the amount of uranium-235 required for various types of nuclear reactors and their energy output.
Video transcript
For a standard nuclear reactor, approximately fission of 1 kilogram of uranium-235 produces about 24,000 megawatt-hours of electricity. Typically, 3-5% of enriched uranium-235 is used in fuel rods, which means the exact quantity depends on the reactor's size and type. Hundreds of kilograms of enriched uranium-235 may be required for a large reactor.
