Tileable Nuclear Reactor Blueprint with Adaptive Regulation (1.76 GW)
A 12-reactor minimal setup that switches reactors on only as demand rises; starter and tile pieces let it grow.

Output (computed)
The output shown is computed by this site from the blueprint itself, using normal-quality numbers from the official wiki. Each reactor makes 40 MW of heat plus another 40 MW for every fuelled reactor touching it, which is why a 2x2 block gives 480 MW and a long double row gives 160 MW per reactor minus 160 MW. A heat exchanger turns at most 10 MW of heat into steam and a steam turbine turns that steam into 5.82 MW, so the plant delivers whichever of the three totals is smallest: reactor heat, exchanger capacity or turbine capacity.
Heat exchanger and turbine ratio
A plant is balanced when its exchangers can take all the reactor heat and its turbines can use all the steam. With normal-quality buildings that is one heat exchanger for every 10 MW of heat and about 1.72 turbines per exchanger, because one exchanger makes roughly 103 steam per second and one turbine uses 60. Compare this plant's counts with that: more turbines than needed is harmless, but too few exchangers caps the output.
How fuel cells get in
Fuel cells are brought by logistic robots to requester chests next to the reactors, so the plant needs a logistic network with fuel cells in it. Used cells must be taken out as well, because a reactor holding spent cells stops accepting new ones. A fuel cell burns for 200 seconds whether or not the power is used, so the useful designs only add a cell when the reactor is cool or the steam store is low.
The regulation keeps idle reactors unfuelled. The designer puts the practical limit at the fuel belt's capacity and says a pump is needed every 120 reactors so water and steam pipes do not overextend. If you never need more than 12 reactors, the minimal setup alone is enough.
