Regulations require all nuclear reactor containment domes to be able to withstand the impact of a fully loaded passenger jet. It is literally a requirement - see https://en.wikipedia.org/wiki/Containment_building. You can also check out this video of experiments investigating the strength of containment-dome-like reinforced concrete: https://www.youtube.com/watch?v=F4CX-9lkRMQ
I genuinely appreciate this response. It is good to know that someone is thinking about preventing nuclear from being used as an attack vector, while others in the thread think nuclear can do no wrong.
