F1. Gaseous Diffusion.

F1. Gaseous Diffusion. At the Portsmouth Gaseous Diffusion Enrichment Plant, uranium gas is pumped through miles of pipe that filter the smaller, lighter uranium-235 atoms from uranium-238. U-235 sustains the nuclear chain reaction in reactors and in bombs. The three "process buildings" are among the largest industrial structures in the world; each is half a mile long; they operate around the clock and can together consume in a day as much electricity as the city of Memphis, Tennessee. Piketon, Ohio. 27 July 1983.
