Yes, Yet Another Reactor Design :)
- Symmetric, compact, mostly square (~75x80), not too ugly
- Logistics on one end, water inlet on the other
- 14 separate water inlets so you can have ~200 pipe segments between pumps
- No smarts, no steam storage; just nukes, exchangers, turbines
- Should give sustained 1120MW output. Energy screen lists 1.1GW, but production shows constant 692k steam (and water) per minute, which matches (10 / 0.097=)103.09 water/s 112 exchangers60 seconds (https://wiki.factorio.com/Heat_exchanger)
Design logic is simple: heat is distributed to 14 heat banks of 8 exchangers, each feeding to 14 turbines (for 112 exchangers and 196 turbines). However, to make everything fit compact and look nice I had to fiddle a bit:
- Exchangers are 2 groups each to the sides at the bottom and 2x5 at top.
- The central 2x3 groups on the top connect to the top turbines which are 2x6 (interconnected for compactness and with two holes for substations) with the seven "missing" ones between the pipes.
- The next 2 groups in the top connect to the row of 12 turbines on the sides, with two loose ones between the pipes
- The final two groups in the center are standard 2x7
- The bottom heat exchangers are in a bank of 7 on the outside and a bank of 9 (curled around) on the inside, to make use of the space below the reactors so I could shave off two tiles. This means that the outer bank is now 7 reactors with 12 turbines, while the inner bank is 9 reactors with 18 turbines. The ratios almost add up (1.72 * 7=12.04, 1.72 * 9=15.48), but to compensate I interconnected the two banks so the .04 excess steam can be used by the inner bank. It also means the inner bank now needs 9x103.09=928 water/s, but that should still be fine with 200 pipe segments between pumps.
Water for the lower heat banks is piped around the central heatbank and first group of turbines, the rest is connected directly to the central 'aisle' at the top.
