You could try to make a Chunkloaddetector using Minecrafts "freezing on chunkload until it comes to MC 1.3"-Repeaters + Redpower-Repeaters which are not freezing, to make two classical Repeatertimers, and then check if they are synchronized, and if not, then you have an easy Chunkloaddetector.

Anyway, I gave that info to our techmarines, and they said that is viable and know how to build it.
So thanks, the project for making this reactor has started =^o^=
