This is a fantastic megaprint, more than enough power for my game and very fun to look around, the only issue I have is the GRN 4.0 has a few rail lines and pillars that intersect with this, would be great to see a slightly alteration of supply lines into the factory that weave around the GRN. (Not connected to GRN, just works around it so pillars and rails don't collide)

@JarlWolfe. Sure you can! I thought the same way when i wanted to start my first nuclear setup. but it is no more complicated than any other factory. All you need is time for building everything. Try starting reverse build, start with some reactors and think about how much fuel you want to produce for them. then you build the production line for the fuel rods. then the next machines to produce the parts needed for the rods, then for those machines and so on. you can do this with even numbers the whole time, overclocking or underclocking helps a lot.

Right now i am building another nuclear setup, 4 times bigger and more power than this megaprint (over 1 TW!)

I've had Satisfactory since day 1. I've come back and started fresh quite a few times, probably clocked 500 hours in the game but I always fell apart around Nuclear stage. I thought this time, I'm going to do it.. but I'll try out someone's blueprint first. I shouldn't have started with yours. Makes me want to quit. I could NEVER build something this complex.

@Lubbo - Looks like a water flow problem to one of the Uranium fuel rod plants. You're right; turning it off to fill it up completely should stabilize the system.

@Vyleria: I guess it's one of those fed with ficsonium. I don't have this problem but i think there could be an issue with distribution of the ficsonium rods OR the water supply. It could help to deactivate the reactor for a few seconds.

After a few hours of running, I am noticing that one of the power plants drops for a minute or two every now and then. I'll see if I can diagnose and report back.

It's running for many hours now in my save while i am building some new factories. i checked the power production now and then, no problems so far. i also checked the buffers for nuclear waste, there is no buildup. All machines run as they should, so far so good. I recommend building some batteries as a buffer.

Very cool build. Far as I can tell, works like a charm. It was fun to tour as well. My last nuclear plant was spread out in smaller factories across the world, so it was neat seeing how it could look condensed.

UPDATE: Made some minor changes to this megaprint so that it's now compatible with Hornslet 1.0 The Main Line

UPDATE: a power line was missing. i corrected that. The plant should now work as planned.
