FACTORIO NUCLEAR REACTOR SETUP MODS

In vanilla factorio, without mods which change any of these values, the optimal ratio will be the same. There are also times between day and night called dusk and dawn which complicate the calculations. These include the power generation of a solar panel, the energy storage of an accumulator, the length of a day, and the length of a night. The optimal ratio of accumulators per solar panel relies on many values in the game. This is taken from Accumulator / Solar Panel Ratio (which calculates this in an impressive mathematical way!) and another post in that thread (which calculates the solar panel to megawatt ratio in a different way).Ī small 9x9 setup demonstrating the 20:24 'close enough' ratio above. This means that you need 1.428 MW of production (of solar panels) and 100MJ of storage to provide 1 MW of power over one day-night cycle.Ī 'close enough' ratio is 20:24:1 accumulators to solar panels to megawatts required (for example, a factory requiring 10 MW can be approximately entirely powered, day and night, by 200 accumulators and 240 solar panels - this approximation differs from optimal only in that it calls for 20 extra solar panels, which is negligible but remember that the difference between the 'close enough' ratio and the optimal ratio increases as you add more solar panels). The optimal ratio is 0.84 (21:25) accumulators per solar panel, and 23.8 solar panels per megawatt required by your factory (this ratio accounts for solar panels needed to charge the accumulators). My typical setup is to have these feeding a 'science bus' that runs parallel to my main bus then feeds all of them into a row of labs.A possible setup Solar panels and accumulators Optimal ratio In a few cases there's an X meaning 'leave this side blank' (for example in grey science to combine a half-belt of steel with a half-belt of regular magazines). There's constant combinators on each belt as notes for myself of what materials to send in from the bus. You can use a calculator to figure out ratios of machines making intermediate products to the final science packs, or just tack assemblers on as shortages happen.

Excess dull uranium is shipped by train to a separate outpost making uranium ammo.Īs requested by here's some science blueprints I've made: Īll are designed to take input belts on the right then scale to the left pretty easily. Any excess shiny uranium once the power plant is satisfied gets turned into nuclear train fuel. Takes in uranium ore, refines it, saves up enough shiny uranium to start Kovarex, then makes nuclear powerplant fuel. Here's 'Oak Ridge', my most recent iteration of a nuclear processing design. Typically, I'll have the train outpost feeding the wall also have an artillery battery, and a fun pastime is to drop a couple shells in a bunch of biter camps, then watch them all swarm towards the wall. With all the weapons upgrades researched, this can mow down behemoth biters as fast as they come. The 3:1 ratio gives good overlapping fields of fire to the flamethrowers while keeping the power pole wiring simple and easily tileable. Behind that are flamethrower and laser turrets. Belt of uranium ammo is fed by burner inserters, which means this should keep firing even in a power outage (have I ever had a power outage long enough for that to be necessary? no, but that's beside the point). Here is my late-game 'lol come at me bro' biter defense wall, also tileable. Here's a T junction that lines up with it, I'm particularly happy with how this design turned out. The length between signals is sufficient to let me run 2 locomotive, 8 car trains if I want (currently they're all 1x4s though). I made that into a blueprint, with the power poles and signals very carefully lined up to make it tileable. Here is an example straight-line segment. My current main save, which I have 'only' 30 hours in, I decided to ridiculously future-proof my train network from the start, and run 4-lane rails everywhere.

I think on a future playthrough I may go out of my way to arrange the bus in Roy G. Off to the left is an assembly producing artillery shells and feeding them to logistic robots.ĭidn't aim to have the belts look like a rainbow but I really like it.
