WebDec 2, 2024 · Enriching Uranium. The nuclear fuel used in a nuclear reactor needs to have a higher concentration of the U 235 isotope than that which exists in natural uranium ore. U 235 when concentrated (or "enriched") is fissionable in light-water reactors (the most common reactor design in the USA). WebSource isotope gas mix flow is fed to the cascade. Light and heavy fractions are separated. Central part incorporates at least one auxiliary separation stage for intermediary fraction, flow rate and separation point of which correspond to the given concentration of target isotope at least at one of the cascade stages.
