Also depends what buttons - it makes sense to have the "Might need to push quickly in an emergency" buttons big and physical - they're already shown to be treated differently in the current implementation, being larger and red in the photos. But for things not really needed in such a situation? Or even access to things that aren't available within reach otherwise due to size constraints? A touchscreen might be the best solution. There's probably more total sensors in the reactor than there can be physical dials for in a room of that size - there'a probably already some level of ordering which are the "important" ones, or which are at prime real-estate by the operators on the panel and not the other side of the room. There's lots of steps between "Huge array of switches and dials for every possible thing" and "Single ipad in the middle of an empty room", after all.
