A power generation system that can't lose power itself without resulting in a major disaster is far from 'superior'.

What I mean is the spent nuclear fuel must be kept cool at all costs, backups are finite. There's already been a few accidents and many close calls, none as bad as they could of been. Scale up nuclear to find how to bad it can get.
