The Secret City of Oak Ridge is based on the real Secret City within Oak Ridge. During WWII, the Y-12 facility made fuel for the nuclear bomb, and it is still making high quality nuclear products.

Interestingly enough, Oak Ridge is also one of the nicest communities in all of Tennessee, with some of the best schools, housing and highest income. It is a small paradise of engineers and high level government employees and scientists. It has only about 30,000 people there.
