I have operated nuclear plants... I would rather sleep 40 feet from a nuclear plant rather than 1000 feet from a 30,000 pound pressure vessel. The pressure vessel has a much higher likelihood of releasing tremendous potential energy.
I am not talking about wilderness... but less than 1000 feet from a truckstop and freeway.. really. Huge pressure vessels?
