The lab where I work now was sort of the genesis of the atomic bombs. I drive past the Graphite Reactor every day. At one point in time, K-25 (or was it Y-12?) consumed 10% off all the electricity in the US enriching uranium. 10%. In one building. Sobering.
On the bright side, there is a group that is trying to build a full-up FIA race track on the old K-25 site. The only problem is that if you go off into a gravel trap, your car will become contaminated.
