I've been using Nilaus' "inifinitely tileable nuclear" blueprint for a very long time, however 2 things bugged me: First, it's not 100% efficient (pasting his blueprint once puts 12 reactors which have a theoretical limit of 1760MW but they bottleneck at 1.6GW). Second, while it's infinitely tileable, the blueprint itself has 12 reactors, which is A LOT to build when you play in freeplay, making it not a good choice as a first nuclear reactor, so I always ended up building a 2x2 reactor first, then switching to infinitely tileable later on which is annoying as I'll have then another type of nuclear reactor laying around. This blueprint I bring you here solves both those problems.
Pros:
- It is infinitely tileable, maximises neighbouring bonus.
- It is 100% efficient (the theoretical limit of energy will be produced)
- Cheap to build (nothing unnecessary, can use yellow, red, and blue belt as wanted)
- 2x2 setup, ideal even for a first nuclear power plant, so you can be future-proof right away.
- Belt supplied. 2 input blue belts and 2 output blue belts, which will be enough to power 2x9000 nuclear reactors, generating 2.88 TeraWatts of power. If you need even more, 2 blue belts of input and output can be added to double this already ludicrous capacity. Note that while the blueprint uses blue belts you can easily adapt it to use red or even yellow belts, so ideal even in early/mid game in freeplay. I guess you could also adapt it to bot-supplied by putting roboports between the boilets and turbines too.
- If you're not going to use additional supply/return belts, you can place raders near the reactors and always be able to see them in map view (that's another thing that was annoying with Nilaus' blueprint)
- Uranium fuel cells go one way and spent fuel goes the other way, so easy to reprocess spent fuel into uranium near where it is produces. Spent fuel belt is also balanced.
- Aesthetically pleasing (straight powerlines that connect in right angles, well lit up at night, etc...)
Cons:
- Some tiles are left unused in the turbines, so it could probably be a bit more compact, vertically.
- Blueprints designed to be pasted on landfilled water require you to be careful with the landfilling (remember to save in case you misclick)
