With 80 turbines the plant delivers about 466 MW; the reactors make 480 MW of heat, so 3 more turbines would use it all.

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
The blueprint has no automatic fuel delivery: insert fuel cells by hand or connect your own belt or robot supply, and remove spent cells, which otherwise block new fuel. A fuel cell burns for 200 seconds whether or not the power is used.
There is no fuel automation in the blueprint, which keeps it simple: load cells by hand or bring your own belt or robots.

Copy the string and press Import string on the shortcut bar in the game, then paste. It was exported from the Factorio 2.0 version shown above. This site decoded it and counted the reactors, exchangers and turbines, but did not import it in the game; check the designer's notes above for water and start-up needs.
