Not necessarily. Plutonium has about 90 TJ/kg energy density. At $500/g, that comes out to about 180 MJ/$, or 2 c/kWh. That’s only a bit below half of coal’s 4.63 c/kWh. And this is only for the fuel! If you were to go the all-plutonium route, it would probably wind up being more expensive than coal.

High-yield fusion would be another matter.
You have to have fusion. With fision you have to clean too much.
And the OP wanted the fusion as well.
