Factorio nuclear reactor setup

The nuclear reactor generates heat by burning uranium fuel cells. The heat can be used in a heat exchanger to produce steam which can be used to generate power. Unlike other forms of power generation, it is load-independent – each fuel cell will always be used completely in 200 seconds, regardless of load or the temperature of the reactor. To prevent wasting fuel, excess power can be ...

Last week I accidentally ran out of nuclear fuel cells (its a long story). It was such a pain going to manually reload 70+ reactors that I decided it was time to update my fuel loading blueprint to include auto-start. Basic idea: count fuel loaded and unloaded. On start, both counts are zero. Load in one cell; after five minutes, the used fuel ...One ingredient requires bigger setup than nuclear fuel. Another ingredient requires U-235 or spent nuclear fuel (small chance). Fusion requires input power to run - consumes 500 MW to generate 2 GW, which is difficult to jumpstart without nuclear. I also had an instance where a set of fusion reactors somehow spiraled into blackout.Connect at least 7 water pumps. Manually insert two Fuel cells in each rector for startup. Robot based, but can be easily retrofitted with belts. Fuel economizer: Fuel cells are inserted into Reactors only when Steam tank storage goes below 100K steam.

Storage of …Re: [1.1.57] Nuclear reactor suddenly got -i °C temperature. by ignatio » Wed Apr 20, 2022 12:28 am. Yes, that's fair enough. It didn't cause any lasting effects either, once I rebuilt the heatpipe network. I'm a bit curious how the temperature can take on a value that gets written out as "-i".

Nuclear reactor has low temperature. Hello fellow engineers! I have some trouble with my reactor setup. Reactor is at about 529 degrees (Celsius) suddenly. I do not get why. It worked fine for about 10 in game hours until now. It has plenty of fuel and my heat exchanger are receiving enough water. Now the reactor cannot heat up the heat pipes ...Transmission loss wasn't the right term but it can amount to the same thing. The effective throughput of heat in a heat pipeline declines with the length of the pipeline (see wiki).E.g. if you you stick 20 heat exchangers at the end of a single width pipeline 200 tiles long, you're not going to get anything like full output from them, even if the reactor array is producing GW of heat.Hello everyone!Megabase Factory step-by-step - Step 40: Today, it's time to convert some of our precious uranium to nuclear fuel for our trains and reactor c...2x3 Reactors = 800MW = 16+32+32 Heatexchangers. 2x4 Reactors = 1120MW = 16+32+32+32 Heatexchangers. Because of the increment of 16/32 i choose the ratio of 1 waterpump, 8 heatexchangers and 14 Turbines. This screenshots shows my modular powerplant.This setup has 8 seperate water supplies, going to 8 seperate HX lines. The steam lines are also seperated in 8 lines, and have steambuffer at the end of the turbines. (i did this for future setups that require seperate pipes due to throughput) This is not perfect ratio of Turbines to Reactor/HX for the sake of symmetry its slightly ...

I recently built a nuclear power plant with four reactors in a 2x2 configuration. I was using the ratios of reactors to exchangers to turbines described in the wiki and I had the whole thing set up so that you could flip a switch and activate reactors sequentially, with the correct number of exchangers and turbines engaging for each subsequent reactor.Using productivity modules will substantially increase that, up to 7.84 reactor-seconds per second, which would almost let you run 8 reactors continuously just from basic processing alone. If you do a smart-reactor setup of some sort, that U-235 consumption will be drastically cut, as well, as you say you're only drawing ~20MW on average.The inserter that takes the empty fuel cell out waits for a signal (steam < set amount (around 60% of the total capacity)). It then takes out the fuel cell, which pulses a signal through to the inserter that fills the reactor (maximum stack capacity set to 1 so it won't fill the reactor with 3 cells).The main thing to remember is that Factorio generally follows the laws of thermodynamics; if your nuclear reactor produces 40 megawatts of heat, you can get a maximum of 40 megawatts of electricity out the other side. ... As far as I can tell, the absolute smallest perfect-ratio setup possible is: 292 nuclear reactors 400 offshore pumpsThought it was time to give back to this great community. It's my first nuclear setup so thoughts / advice / tips roasts welcome :) 4 blueprints for my Nuclear setup.

I'll be playing Factorio with Seablock and Brave New World mods and high research costs.Re: Modular 2xN nuclear power plant. by mward » Thu Feb 25, 2021 4:42 pm. My version is designed to be built with the middle part over a lake which is filled in with landfill, leaving two narrow trenches in the middle for the water pumps. After placing the blueprint, fill in the trench and add the last two pieces of heatpipe.Hook up water and power (to start) Schedule trains with Iron Plate and Uranium Ore. Place 40 U235 into the kovarex centrifuge. Insert initial fuel cells into both reactors (preferably in quick succession, remove any excess) You're done! Keep sending supply trains and the oven will take care of the rest.Nuclear reactors are an incredibly efficient way to generate power, even early in the game. The trick is really to use steam tanks and circuit control to limit the fuel consumption. My (still rather small) factory requires currently around 60 MW and uses the 2 reactor, 160 MW setup as main power supply.hope you guys enjoy this blueprint and maybe it'll help inspire other more creative designs and challenge others to design a better tile-able compact design. Blueprint Images: 1: 1/2 of 2x6 reactor/heat exchanger. 2: Nuclear Water Unloading. 3: 152 turbine setup.Nuclear setup for dummies. Question. Greetings! Could you help out a nuclear power noob? I've set up a nuclear power setup by using the factorio wiki's tutorial for ratios. …It's a 100% efficient design: spent fuel stays in the reactors until steam drops below a threshold. The inserters removing the spent cells send a pulse to the fresh fuel cell inserters, which insert exactly one new cell into each reactor simultaneously to maximize the adjacency bonus.The inserter that takes the empty fuel cell out waits for a signal (steam < set amount (around 60% of the total capacity)). It then takes out the fuel cell, which pulses a signal through to the inserter that fills the reactor (maximum stack capacity set to 1 so it won't fill the reactor with 3 cells).Speaking of storage, back when my 72 reactor setup was just 24 reactors I accidentally broke nuclear fuel production. At that point All the fuel my factory would ever use was limited to a box and whatever was already on belts. The factory ran for hours before I noticed by happenstance that one of the belt lanes was empty and fixed it.hope you guys enjoy this blueprint and maybe it'll help inspire other more creative designs and challenge others to design a better tile-able compact design. Blueprint Images: 1: 1/2 of 2x6 reactor/heat exchanger. 2: Nuclear Water Unloading. 3: 152 turbine setup.

A 2x2 reactor setup generates 480 MW, but that'd require quadruple the uranium processing to keep fed. The difficulty with larger reactor setups is keeping your heat exchangers fed with water (and making sure the steam gets to the turbines. A single offshore pump can supply water for 11-12 exchangers. A 2x1 setup can power 16 …

A beacon is a device that transmits module effects to nearby machines, in a 9×9 square. The effects are transmitted at only half efficiency. However, a beacon allows transmitting the effect of a module to multiple machines and the effect of all beacons in range of a single machine stacks. Additionally, beacons can provide boosts beyond the normal limits of internal module slots, such as ...Radioactive iodine uptake (RAIU) tests thyroid function.

You should use adjacent underground pipes to separate each fluid line.What is the update time for a 0 reactor nuclear power plant? Is it 0 or a very very small number? Edit: Here is a list of minimum items required for nuclear power setups 1 reactor setup: 1 reactor, 1 pump, 4 heat exchange, 7 turbine, 1 inserter, 1 belt / 1 roboport + 1 chest, 1 power pole / 1 substation 2x1 reactor setup:Oh no way. Thanks! It is for this reason that most people that use nuclear power tend to have a 'storage area' for steam that gets filled up when the reactor is running, and allows a new fuel cell to be inserted into the reactors when storage levels fall to a set minimum. This way your reactors dont waste fuel running all the time as they do ...You all know the problem: You absolutely, positively need to power your 26.000 electric furnaces or 10.000 beacons, yet most nuclear setups are ugly 2xN tubes, powered by thousands of robots, so you fall back to solar energy and spend the next months paving the whole map with solar panels. Fret not and have a look at this 32 reactor setup!Small modular nuclear reactors designed to be deployed off-grid at remote sites.

It's perfectly fine to have full steam tanks and the reactor heating up to 998°C before fuel runs out. And adding heat pipes anywhere there is space adds to that buffer. Gouldukat.Also, you might want to remember that nuclear reactors receive a 100% bonus in generating power when placed next to other reactors, so you might ideally want to group them together. Overall a completely optimized setup to generate nuclear power is having 292 nuclear reactors, 400 offshore pumps, 4656 heat exchangers and 8000 …In your setup you turn on nuclear at 40% charge and that will charge the accumulators by using nuclear power. And you turn nuclear of at 80% charge. That means 40% accumulator storage is bought by fuel. 40% came from somewhere and is never touched (except in an emergency). And only 20% is actually storing solar power (worst case).Community-run subreddit for the game Factorio made by Wube Software. ...

The first reactor "basic nuclear reactor" produce 4mW with efficency of 80%, the second reactor "extreme nuclear reactor" produce 1gW with efficensy of 100%.While its uses a lot more heatpipes and can handle only 477.24MW, but bit more compact. Its only 36 x 58/60, which is 228/221kW/tile compared to 217kW/tile of your design. It's also buildable from outside with included roboport and can be tiled. This is a compact 46x48 and cheap to make 2x2 Nuclear Reactor. 480W constant/ 489W peak.A 2x2 reactor setup gets 3x neighbor bonuses on each reactor, giving you 12 reactors worth of output. This seems to be the sweet spot--it's a huge improvement on a lone reactor or 1x2 reactor, but diminishing returns kick in hard above 2x2. A 4x2 setup produces 28 reactors of output--2.33x the heat for 2x the cost.Don't worry if any of the reactors start flashing with a 'No fuel' icon. This is because there is enough stored steam for the reactors to be idle. There are programmable speakers for 3 events. First when the amount of nuclear fuel in the requester chests falls below 100 cells. You will receive this alert when you first place the build. Factorio nuclear reactor setup, Nuclear setup 12 reactors. by Darqbit » Thu May 18, 2017 11:52 pm. Hi everyone ! My friend gedeon and i used to build this nuclear setup and i want to share it with you ! Cause it's beautiful to see. 12 Reactors, 176 heat exchangers, 16 Offshore pumps, 303 steam turbines for a 1760MW total energy. Map with electric filter. Electric Map Overview., Step 1) Process uranium ore to U-238 and U-235 in a centrifuge (99.3% chance for U-238, 0.7% chance for U-235) Step 2) Repeat step 1 until you have 40 U-235. Step 3) Kovarex processing. Step 4) Make fuel, give it to the reactors., The Kovarex enrichment process is named after Michal Kovařík, lead designer of Factorio and co-owner of Wube, whose online nick is kovarex (which he usually spells lowercase). [1] In the real world, uranium-235 is the most common fissile isotope of uranium and makes up approximately 0.72% of naturally-occurring uranium, with the other 99.28% ..., Start with a 2 reactor 160MW design: When you need more energy, you can mirror and extend to 480 MW: Compared to optimal setups, this wastes 4 turbines (for …, Secondly, fluids at high throughputs lose pressure according to number of pipe tiles. Replace the final stretch of pipe leading to the exchangers with more undergrounds. It's a 4-reactor setup alright, but those heat exchangers only consume 160MW. 2/3 of your heat is wasted, this setup would be ideal for 2 reactors., The optimal setup is building reactors in a 2*N grid and besides the 4 reactors on the sides every single reactor in the middle gives the same amount of energy. ... I think in a game like Factorio, nuclear power just fits very well. Although it's been marvelously implemented, it just needs some tweaks to get it in a better state of affairs ..., In general, nuclear power is produced by the following production chain: Uranium ore is mined and processed to uranium-235 and uranium-238, then uranium fuel cells are created from the two. These fuel cells are then burned in a nuclear reactor to create heat. The heat can be used to convert water to steam using a heat exchanger and the steam ..., Because a continuous supply of uranium fuel cell is critical to maintaining a nuclear reactor, the circuit network can be used to set up a system where uranium-235 and uranium-238 are conserved for the production of nuclear fuel before other uses., Or nuclear power in SE in general. When i see other people's nuclear powered ships they have a ratio of heat exchangers to condenser turbines at somewhere around 1:3 and claim that works continuously. When i build a reactor setup my heat exchangers produce 103 steam/s while the condenser turbines draw 80 steam/s each meaning i'm at a ratio of 4:5., One ingredient requires bigger setup than nuclear fuel. Another ingredient requires U-235 or spent nuclear fuel (small chance). Fusion requires input power to run - consumes 500 MW to generate 2 GW, which is difficult to jumpstart without nuclear. I also had an instance where a set of fusion reactors somehow spiraled into blackout., As with many automagic setups: you will need to manually insert the very first fuel into each reactor core, but it will require zero attention after. Nice feature about this setup is that if there is a nuclear fuel shortage, the input inserters remain poised to grab the next one as soon as it arrives, thanks to the memory cell holding the signal., Wait. Features: compact design (try to find more compact ) one side for water pumps (easy to connect with lake) smart nuclear fuel consumption without losses. up to 477 MW energy. safe separated net for reactor support system in case when consumption of energy greater then production. indication of steam and fuel in reactor., One ingredient requires bigger setup than nuclear fuel. Another ingredient requires U-235 or spent nuclear fuel (small chance). Fusion requires input power to run - consumes 500 MW to generate 2 GW, which is difficult to jumpstart without nuclear. I also had an instance where a set of fusion reactors somehow spiraled into blackout., Modular nuclear power plant. I've rapidly outgrown the capacity of my single nuclear reactor, so am looking to build something modular, so I can initially build it with 2 reactors, and then add more later without having to demolish anything. So far I've come up with this which seems to work well with 2 or 4 reactors, but how many pipes ..., Originally posted by Linda Hartlen: because it allows for easy shutoff off the reactors. You can measure the amount of steam in the tank and have a simple setup that shuts off the feeding of the reactors when you have a set amount. Since reactors always run, they don't stop using fuel like the steam engines do., 31 votes, 16 comments. true. Compact 800 MW Nuclear Reactor with Auto Throttling. In all its glroy. Here's my take on a 2x3 800 MW Nuclear Reactor. 2x3 seemed like a good compromise to me between getting some 300% neighbor bonuses and before the space and heat pipe issues that come with 2x4. The design is tested to sustain 800 MW, the maximum theoretical output for 2x3., Many people use more than one email account. In fact, most people use at least an email account for work and a personal email account. If you use an iPhone, you can set up multiple..., Add realistic nuclear reactors including a breeder reactor type and cooling tower. The reactors must be controlled through integrated circuit interface signals. The thermal energy output is dynamic and depends on reactor core temperature. The reactors require sophisticated designs of their cooling system and heat-pipe network. If the operational conditions aren't met then a reactor core ..., Important to note that this reactor can only be built on water and landfill, to allow the offshore pumps to be placed before filling the rest, and they can't be later removed. Recommendation: Place the steam pipe after the first set of turbines. This reduces the pressure on that pipe and makes it balance better. 15., Circuit network. Circuit networks are built using red or green wire, and enable the control of receivers, based upon information broadcast onto the network by connected senders. Most senders are storage devices, and broadcast their information onto a specific channel, based on the item or liquid the storage device contains., Once it had gotten to 99% it will connect itself back to the main grid. #2. Power overall is way too low to power the pumps and the block averaged over 910c since the pumps cant get the hot water away fast enough. Once the average temp hits 876c it will connect back. Not normally an issue, but it happens., Don't worry if any of the reactors start flashing with a 'No fuel' icon. This is because there is enough stored steam for the reactors to be idle. There are programmable speakers for 3 events. First when the amount of nuclear fuel in the requester chests falls below 100 cells. You will receive this alert when you first place the build., As with many automagic setups: you will need to manually insert the very first fuel into each reactor core, but it will require zero attention after. Nice feature about this setup is that if there is a nuclear fuel shortage, the input inserters remain poised to grab the next one as soon as it arrives, thanks to the memory cell holding the signal., 480MW Nuclear power plant. -- NEEDS U235 SEED INTO KOVAREX--. Input Raw Uranium, Iron Plates, and 6-8x water pipes to generate 480MW of nuclear power. Automatically starts nuclear power production when overflow of cells acheived. Manages fuel usage based on need. Load tested at 100%, 50%, 10%, and 100%to 0% stress test after loading fuel to max ..., An 8 core (2x4) nuclear reactor which can supply 865MW. It is a "dumb" setup, in that it will not "smartly" save nuclear fuel by throttling down when the maximum load is not met. This was a deliberate design choice: By the time you need an 8 core reactor, nuclear fuel will be plentiful due to Kovarex Enrichment., The total sustained heat output of your plant is based on your active reactors. 1 reactor is 40MW. A pair of reactors is 2x40 +100% => 160MW. 2x2 is 4x40 +200% => 480MW. Every pair of reactors tacked on the end (for a 2 by X reactor )is another 2x40 +300% => 320MW. The power I get just depends on demand., 4 roboports. Overview. Symmetrical with the exception of one arithmetic combinator and plenty room for walking. Production. Produces ~1.1GW. Tested with many laser turrets, radars and bots. Closer look at one half. You could copy paste one side to create the another, with the exception of outside water piping. Fuel control., 1.1 GW is the max you can get out of 8 cores. The middle four have a neighbor bonus of 3 so they generate 160MW. The 4 reactors at the ends each have a bonus of 2 so they generate 120MW. 4 120 + 4 160 = 1120MW ≈ 1.1GW. The rest of the design is just a matter of pushing enough steam around to actually get that much power., Fill up you nuclear reactors just right, with this easy circuitry.Get the free Demo: http://bit.ly/GetFactorio, Put a heat exchanger on the section and add tank - pump - tank - turbine - turbine. While the temperature is above 500° the heat exchanger continuously produces steam and the steam content of the first tank is >0. When the temperature drops, the tank is quickly emptied by the pump and steam=0. Blueprint: This should be connected to the heat ..., Design / Blueprint. And a final compact nuclear reactor, this time 2x3 : Compact, (almost) symmetrical, nicely rectangular (about 60x70) Substations on the outsides for tileability. reactor logic / logistics at the bottom, water intake at the top (so you can build it away from a lake) all inlets are separate connectors to 8 exchangers each, so ..., Double Reactor Nuclear Plant. I usually start with a 2x4 reactor setup (8 reactors in total) and when I start getting several beacon outposts, I build a setup containing 32 reactors. Don't bother with 1-2 reactor setups. Neighbour bonus should be exploited. Little tip, don't bother with storing the steam., The whole nuclear mechanics are extremely satisfying. May it be dropping nukes or watch the power just rise a magnitude when the turbines roll on. A makeshift reactor just to cover your droid's power hunger or the real deal multi armed monstrosity with sophisticated water supply churning out steam in the gigawatt scale.
