Of course, those nuclear plants are connected to that grid and they will be without power

The nuclear power plants are not reliant on the grid to have an electricity supply.
They ARE the electricity supply.

Holy Fear Monger Batman!
Yes, a nuclear power plant without electricity to cool it's rods is bad, really bad.
Yes, a really bad CME has the potential to 'fry the grid'
Yes, there is such a thing as a power generator that runs off fuel. I'm sure anyone who's ever built a nuke plant has never thought of that.
As dude said, pics or it didn't happen!
Do you have an references of plants not being backed up? I'm more inclined to think the people smart enough to construct these, are smart enough to think of backup plans for if the grid goes down. Do you have any evidence to show otherwise? Or, is my hunch correct, and your just putting diarrhea on the web to scare the [snip] out of people?

Completely untrue. If the plant in Japan had been self-sustaining we wouldn't have known it even existed.

FYI nuclear reactors have a primary cooling system that pumps water which is driven by turbines that use steam from the reactor to turn - eg self sufficient (which is why Fukushima has more to it than meets the eye)
in event of solar maximum the reactors (which are usually over-over-engineered) would not be affected in such a way as to cause meltdown
stuxnet is a different story
some research that may help you includes
en.wikipedia.org...
number of reactors:
In 2007, the IAEA reported there were 439 nuclear power reactors in operation in the world,[3] operating in 31 countries.[4] Also, more than 150 naval vessels using nuclear propulsion have been built
en.wikipedia.org...
Cooling A nuclear reactor coolant — usually water but sometimes a gas or a liquid metal or molten salt — is circulated past the reactor core to absorb the heat that it generates. The heat is carried away from the reactor and is then used to generate steam. Most reactor systems employ a cooling system that is physically separated from the water that will be boiled to produce pressurized steam for the turbines, like the pressurized water reactor. But in some reactors the water for the steam turbines is boiled directly by the reactor core, for example the boiling water reactor.[5]
enjoy - its a blast
Nuclear power plants are not isolated electrically. They are tied into the power grid and are also dependent upon it. There is a postulated accident for nuclear power stations called “Station Blackout,” where all off-site power is lost. Every nuclear power plant must prove to the NRC that they have the ability to withstand this event without core damage. Every US nuclear power plant has emergency diesel generators just for this purpose. These are designed to start automatically in the event of the loss of off-site power. This kind of event has actually happened before in the USA, and the systems responded as designed, and off-site power was restored within a reasonable period of time.

Titanic?
there's another conspiracy - They say it wasnt the Titanic at all, but the re-badged sister ship, an insurance job, and all manner of sneaky stuff
I am pretty sure Titanic was not nuclear tho'

No, this is all incorrect. Nuclear power plants use water as a coolant, but, for example, when Fukushima could not access electricity, that was when it began to turn for the worse:

You may need to research that a bit before making that argument :-)
reactors make steam......
To circulate cooling water when the reactor is shut down and not producing electricity, cooling pumps can be powered by other units on-site, by other units off-site through the grid, or by diesel generators.[55][57] In addition, boiling water reactors have steam-turbine driven emergency core cooling systems that can be directly operated by steam still being produced after a reactor shutdown, which can inject water directly into the reactor.[58] Steam turbines results in less dependence on emergency generators, but steam turbines only operate so long as the reactor is producing steam. Some electrical power, provided by batteries, is needed to operate the valves and monitoring systems.
