Not really - for either system, the transformer substations are the part that's vulnerable to drones. Any munition capable of breaching the outer containment structure of a nuclear power plant (let alone impacting the core, dozens to hundreds of meters further inside) is closer to a bunker buster than a drone.

What I'd really like to see though is heavy subsidies for synthetic e-fuel plants running a carbon negative process during off peak hours. That would work with both solar & nuclear.
