I don't know how exactly it works, but AE2 has a whitelist for spatial io. I don't think it would be a huge gameplay breaker to digitalize the reactor and put it down somewhere else.

Multiblocks do not play nicely with being broken/reassembled en-masse, and I don't see this as adding enough to bother spending the time to make it work.

It's sufficiently low priority to be "no chance".

you should give it a shot, the reactor has no problems with being moved around with remain in motion.

probably the same applies to the turbine.
