How many nuclear power plants would we need to get us to 100%

That would put the number for us somewhere in the thousand range or 20 or so per state. I know I'm not ready for that.
I don't see a way to fuel that many reactors even if we started reusing the spent fuel as some suggest.

From what I've read there isn't enough known deposits to even get there. I may be wrong.

Where would we get the water to cool them? A nuclear power plant takes more water for cooling than a coal plant does. The generator itself not but the reactor sure will.

I just don't see how we can get there from here using nuclear as our prime mode of making our electricity.
If I'm right Japan is smaller than California in area and they have something like 56 or had something like 56 operating nuclear power plants before fukushima. Man o man.

Thanks
