nuclear power plants

Why are nuclear power plants so expensive to build? I would assume at least 500mill for the structure etc, and probably that much for the nuclear elements needed and testing - but 8 billion or more? Seriously?

You struck a curious nerve in me.  Has there ever been a nuclear reactor that's actually "blown[n] fucking sky high" outside of SimCity?

Bar what just happened in Japan, that is; it'd be too easy to list and would ignore the real problem: the difficulty of safely enduring a 9.0 earthquake.
