The goal of this plant is to be easy to hook up while also providing full power. All sixteen offshore pump hookups are right next to each other at the top of the plant, meaning you only need to edge off a lake. There is no need to landfill in the middle of a lake.
The large number of fluid pumps help ensure the heat exchangers are kept wet. As a result though, it means that the plant must be hooked up to an external power grid before it will generate power. Unpowered pumps mean no water.
Measuring the exact power output is tough, given that the game truncates to a tenth of a GW. Connecting two of the plants together and running for an hour shows that they combine to generate 3.5 GW, which means that each plant is at least 1.75 GW. Given that the theoretical maximum for a 12 reactor plant is 1.76 GW, I think it is fair to call these full power.

The plant is divided into sixteenths, each consisting of one pump, 11 heat exchangers, and 19 steam turbines. Total that makes 16 pumps, 176 heat exchangers, and 304 steam turbines, which is only one extra turbine over what is necessary to extract full power.
There is no fuel cell moderation or steam storage. By the time you are looking at plants like this, you usually have koverex going and know you need the power.
