I tried that in my newer reactor planner, and as a fluid reactor, that design is predicted to produce an average of 895.84 Hu/s while running.
I actually use your planner sometimes. Would 900 hu/s be considered efficient?
I'm actually more interested in overall efficiency (energy-per-fuel) than any other metric. Also, I see people typically concerned with producing multiples of 200 for their reactor. I'm hoping that's less critical for me since I'll be using some GT5u infrastructure.
