I'm running a 15x11x15 reactor with 13 control rods and filled with gelid cryothium. Have three 7x16x7 turbines with ludicrite blocks. I can't get the mb/t in the reactor down to 2000, stays between 3900-4000. I'm using dimension transceivers to move steam and water. In the reactor, water stays between 2000-5000 mb and steam between 46000-48000 mb on the gui. Only one turbine is getting steam at 2000 mb on the gui, the other two do not show any steam in the gui.
Edit: The turbines never reach 1780 rpm, as your page states it should fro the program to do its maths. The program engages the
