Semi-related: If you're interested in the topic, I highly recommend "Plutopia" [1] book which describes in great detail the history of plutonium production, and the consequences of it, near Richland, Washington and Ozyorsk (Russia).

It significantly changed my view on the nuclear energy. Not necessarily because it's inherently bad, but when big money is at stakes and you have incompetent people managing stuff, things can go pretty wild.
