That's another way of saying the aren't designed or operated to handle the known dangers, only to meet a certain bar and hopefully the bar is high enough. In this case, they lost the bet that a 9.0 earthquake wouldn't cause the problems that were predicted
The san diego plant (right on the ocean and near the big fault line) is being reevaluated. Their cooling batteries are only 8 hour while fukushima were 12 hour, but the plant spokesman says not to worry they have backup generators they can move in should the need arise...
of course it wasnt predicted but we are talking about 20year old technology that is outdated (was almost outdated when installed).
its no supprise that they may have gne with lowest cost- thats what business does. and by saying why go with best case not worse case is not any new argument or highlighting anything anybody knows about global economies of scale... its all down to $$$.
No body can predict an earthquake to its magnitude, just a rough geographical location highlighted by fault lines.
at the end of the day, when the earthquake causes the ground to liquidfy, no human engenieering will withstand it when it built to contain this type of material that is very tempremental and requires specific handleing and cooling conditions.
Its not the earthquake as such that cuased the damage to the cores, it was the loss of power and the time its taken to bring back the cooling funstions, which after said 12 to 24 hours , is too late.
so why banter on about it, we know nuclear is not the future it was once promsised to be. but when a company builds a pant for power that is based around return of investment for profit over a 50 year time frame, and 20years in when its just starting to make its long term returns, its not great.
we just have to forget about all this conspiracy and envrionemtal crap and focus on the people affected and how to stop it happening again in the future.
who knows, hydrogen power of the future may see similar issues, so may gas turbine who knows.
end of my supposed mainstream rants .
