The Y-12 Plant in Oak Ridge used the electromagnetic separation method, developed by Ernest Lawrence at University of California-Berkeley, to separate uranium isotopes.

Cindy Kelly: We’re going to start with your name: could you tell us your name and spell it?
Black: My name is Colleen Black, C-O-L-L-E-E-N B-L-A-C-K.
Kelly: Terrific. Good job.
Black: [Laughter.] Thank you.
When Colleen Black's brother was drafted into the Army in 1942, she and her family decided to move to Oak Ridge to contribute to the war effort and bring her brother home.
The K-25 Plant in Oak Ridge used the gaseous diffusion process to enrich uranium.
Gaseous Diffusion Process
The K-25 plant was an enormously ambitious and risky undertaking. A mile-long, U-shaped building, the K-25 plant was the world’s largest roofed building at the time. British scientists working on the “tube alloy,” code for the atomic bomb project, first advocated the gaseous diffusion method in March 1941. Because of the Nazi bombing of England, any production plants had to be located elsewhere.
