Problem
Suggest why isotope nuclear enrichment plants based on gaseous diffusion are so large.Intuitive explanation
Gaseous diffusion separates isotopes by exploiting how lighter molecules diffuse slightly faster through a porous barrier than heavier ones—but the effect is tiny per pass. You need to cascade thousands of stages in series, each one incrementally enriching the product, which requires enormous physical infrastructure. The key insight is that separation power scales with the number of stages, not the size of individual stages, so achieving useful enrichment (like weapons-grade uranium) demands a sprawling industrial complex.
