Twin FBR array

The original compact dual-FBR build.

This blueprint is constructed around the idea that one of each processing plant is enough to keep two FBRs running in perpetuity. You'll need separate infrastructure to make the fuel to get it started, but once it's started, this has the infrastructure and balancing to keep it running. You just need to keep the storage containers stocked. As you'll notice in the screenshot, there is no need to build the whole thing all at once. Each row of turbines and generators is proportioned to consume 1x worth of steam, so build it up slowly as you need the power.

Steel, Coal, Salt, Depleted Uranium, and Glass Scrap are delivered by truck. Slag and Retired Waste are removed by truck. The system can also run on Glass mix and Yellowcake just by switching the import settings on the Glass and Uranium storage. Feel free to belt these as you see fit. Water is supplied by the T3 pipe in the bottom right corner. The two t1 pipes in the bottom are inputs for the starter core fuel (outside) and blanket fuel (inside). Balancers are set to prioritize locally produced fuels over the piped in fuels.
