What distresses me about the nuclear plants is the Morgsatlarge post, 
(the one now lodged in modified form at http://mitnse.com/) describes a 
very reassuring "defense in depth" strategy, where things are allowed to 
fail but the designers have done such a good job that there is always 
another line of defense to fall back to.

Only problem with this:  those fallback positions have been going down 
like dominoes.

It seems to me that the safety systems were all "Looks Good In 
Powerpoint Presentations To Senior Management" safety systems.

On paper, great.

On the ground, as thin as paper.
