Hi, I got back to Monster and I´m about to setup a Big reactor reactor. I last played BR before the Turbine update and already found this: Spotlight Turbine spreadsheet But for the moment I would like to just go with a passive cooled reactor since this will fullfit my needs. And together with a MFR Laser Drill its auto sustaining. Back when I played it the last time a 7x7x3 passive reactor was the most fuel effective one. I used this spreadsheet for the info. But now I set it up equal but the numbers changed. So I´m not sure if its still the most effective one just the calculation on how much energie is gives changed or if it indeed also needs to be restructured to be effective. The turbine spreadsheet is a bit to complex for me and since I¨m not using Turbines atm I think its also irrelevant for me.
