> thousands of people can live deep underground for hundreds of years  yes. in caves. that they exited and entered on a daily basis. that isn't living underground. those people weren't growing food underground. you can't live without energy. there is not enough natural energy underground to allow you to survive underground for many years at a time. you therefore depend on your power plant. your power plant is more important than you yourself. the risk exposure of the power plant is the minimum risk exposure of the people it is supporting.
