What would the effects be if all power grids connected to nuclear reactors abruptly suffered catastrophic failure?

To be more specific, I mean what if every wire, every power cable and transformer on the connected grids to the nuclear power plants all ruptured at once. The transformers literally exploding, the wires and cables tearing open; while the plants themselves became unstable due to sudden extreme power fluctuations.

I want to know what the effects of this widespread damage would be in North America and estimates on how long this disaster's effects would last for.

Thus far a lot of good answers and suggestions have come in. However I am not simply asking about the power plant woes. (Although that feedback was very useful) I am also asking what would happen IF the wires and cables tore,the transformers blew up,etc. Not just immediately connected to the plant. But anywhere that receives power from the plant,in one big burst;all suddenly is rent asunder by a violent surge within the power system.

I apologize for this question not being on point to begin with. It was just harder to frame for me. I am asking what do you do,when all of the copper and conductors in the wires,plant and transformers are torn apart by crystalline protrusions?
