Doc needs 1.21 GW to power the time circuits, and he needs plutonium to generate such an amount of power. While it is possible, it isn't necessary to use a nuclear power source. 1.21 GW is power, not energy, meaning that it's the rate at which the time machine uses energy. Presumably Doc needs the time circuits to be pulling such power for a fraction of a second (as the time jumps in the film are almost instant). So Doc could have built it with either a huge capacitor or a battery, which he would've charged to however much energy the time machine needed (by the DeLorean or through a plug), and then the time machine would use that energy to make a time jump, still pulling 1.21 GW of power. This is analogous to a camera flash, which pulls a lot more power than camera batteries can handle, yet only needs to work for a short amount of time. Doc could have used the same idea for the time circuits.
