That's right it refined uranium hexafluoride into it's various isotopes using
gaseous diffusion, a process requiring immense amounts of power for heating
and refrigeration. They were after the lighter U235 fissile isotope for bomb
making.
This fact together with the absurdity of your question leads me to
believe
you are using scare words in trying to publicize a political event.
No such intent. In fact I didn't take part.
If so, that doesn't belong this forum. I hope the list moderators will
take
note.
My interest was in the mains power characteristics we commonly discuss in the
forum. Sorry you are offended.

I did monitor the voltage during the event and was surprised to find that
utility power stayed right within a half volt, typical of other times of the
day. Given the load changes that occurred, the utilities deserve a lot more
credit for their control systems than I had given them. In the past, sudden
load changes have caused instabilities that caused large scale blackouts. The
impact varied depending on public participation due to press coverage but
Chicago <http://www.chicagobreakingnews

much as 13%.

Is this an indication that to be safe we had better unplug
everything we own
because earth-wide, the load shedding means the utility voltage and frequency
regulation will go haywire?
I'm recalling a college roommate who worked at the Fernald
nuclear refinery
in Ohio (the load the northeast power grid was created for) when they lost one
of eight transformers and utilities all over the east coast called to find out
the source of the frequency change.
