Nuclear ICBMs generally make this a moot point. An advanced enemy can explode a "nuclear reactor" anywhere in your country at any time.
Regarding drones, most reactors are built relatively hardened. For example, they're protected against a 747 flying into it at full speed. So even a drone attack would take an advanced enemy, and they might as well drop a bomb on you.
