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 come in on a belt and inserters load each reactor, so the plant runs without robots; feed the belt from your fuel-cell production and take spent cells out. A fuel cell burns for 200 seconds whether or not the power is used, so belt-fed designs that save fuel use circuit conditions on the inserters to load only when a reactor runs cool.
These designs skip steam buffers to stay small. Prime the system with water before switching on. Each plant has more exchangers and turbines than it needs on its own, so output holds up as you tile copies side by side.
Other plants in this blueprint book
The book also holds a 2x2 480 MW plant and a 2x4 1.1 GW plant, plus no-roboport versions of the 2x1, 2x2 and 2x4. Each has its own string.

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.
