Does anyone have nuclear plan ratios for heat exchangers and steam turbine?
I think % neighbor bonus is lower in Krastorio, but output is 250 MW vs 40MV vanilla? Am I reading it right?
What is right ratio for 6 and 12 nuclear reactor plant?

a single reactor is good for 5 heat exchangers which in turn drive a total of 25 turbines.

a 2x2 setup of reactors is good for 250*1.5*4=1.5GW which means you'd need 30 heat exchangers and 150 turbines.
a 2x3 setup would give you 1.5GW+250*1.75*2=2.36GW so you'd need 47 heat exchangers and 235 turbines
a 2x6 setup is... I'll leave that as an excersize for the reader.

be sure to also calculate the amount of water you're going to need.
