I checked my Agrarian Skies world, and that was actually what I did. Two tesseracts for in/out on the reactor and two for in/out on each turbine. It works.Now there is a thought: Can you use 1 output and 1 input port on the reactor, but (for example) 1 tesseract on each turbine coolant input tuned to the same frequency as the reactor's output tesseract? i.e. it divides the steam equally amongst each?
