I see where you are going with the switches for the turbines. Do you know if steam flow rate through the turbines gets throttled by their individual capacity, like a pipe would? I put the pumps there not only to act as a valve, but also as an attempt to maximize steam availability in the turbines ...

Thanks for your suggestions. I really like that idea of a rolling startup conditions for each turbine stack, with each kicking on separately if the accumulator bank charge continues to drop despite backup power kicking in.
