@ObscuriaLithium looks more like an issue with the pack.
It basically states: The reactor or the energy net is not allowed to request chunks.
Even so it should be allowed to. It is a vanilla mechanic after all.

Unless you can reproduce this exact issue with vanilla+forge+ic2c itself, i am pretty sure IC2Classic isn't at fault.
