That's what I'd like to think, but it doesn't seem to be a good match.

Nuclear plants want constant power output, they are ideal for base load. Solar and wind production vary during the day, and they don't always meet demand. That problem is called the "duck curve": too much is produced during the day and too little just after sunset. That's the reason why the best plants to complement solar and wind are those that can vary their output on demand. And unfortunately, that's typically coal (see Germany). Hydro would be ideal but its capacity depends is limited by the terrain.
