There's going to be some creative nuclear builds out there soon. Unlike coal powered boilers which shut down if the steam engines aren't running at full capacity, the reactors run at 100%, burning fuel cells continuously whether or not the turbines are running at 100%. Additionally, they heat up to 1000 degrees, but the heat exchangers work at 500 degrees. So you can delay putting fuel cells in the reactor until the heat exchangers cool down and stop producing steam. The trick is working out how to measure the temperature drop so that steam is no longer produced. One way would seem to be storing the steam in a tank before it goes into the turbines. If the level starts dropping, it's time to let the reactor have more fuel.

[@Baleur]

It is still baffling to consider that even our most advanced nuclear power plants, or even our future fusion plants, are really only glorified 1800's steam generators.. No matter if you use refined uranium or fusing atoms with the power of incredibly hot plasma contained by well tuned magnetic fields, the ONLY thing you're doing at the end, is to boil water to run a steam turbine. Utterly insane, when you think about it. We're still in the 1800's steam power age, when it all boils down to it.

[@Gwenpool2369]

Boils down? Is that a pun?

[@XxXValtenXxX]

What's more impressive is the fact that we've taken the same concept that started only producing a few kw, to stations that have over 3000 MW of power essentially using the exact same principle, and even the most efficient nuclear plants in the world are only about 30-33% thermally efficient.

If I'm understanding this correctly, The implications of the neighbour bonus are that you should build square blocks of reactors, rather than any other shape. take 4 reactors. Loose, that's 4 reactors. In a straight line, thet's 4, with the two middle reactors getting a 2 bonus, and the outer ones getting 1. so it's 4 + 6 = 10. Arranged in an L shape, nothing changes. In a T shape, the middle reactor gets 3 bonus, the other three, 1 each. (6 bonus = 10 total) Yet, put into a square block, all 4 reactors are adjacent to two others. Thus the bonus is 8, for 12 total. 9 reactors in a square would be 9+4x2+4x3+1x4 = 33 Hmm. Seems like you want to maximize the internal reactors, and keep edges, but especially corners to a minimum. 5 reactors in a T shape is 5+3x1+2x1+1x3= 13 5 in a square plus 1, 5+3x1+3x2+1x1=15 5 in a 'plus' shape is 5+4x1+4x1=13. OK, so it would seem the optimum is very much about having as many adjacencies as physically possible. Not always as straightforward to work out as it seems for a given number of reactors, but it still seems as though the closest approximation to a square that's possible is best in most cases. hmm. for 8 reactors, 2x4 rectangle. 8+2x4+3x4=28, 3x3 square with missing corner 8+4×1+3×2+2×5= 28, while 3x3 with missing edge is 8+3×4+2×2+1×2=26 -which illustrates that you should avoid unneeded corners I guess.

[@ealanyeomans5853]

Wow that’s a lot of math :0

[@Anson_AKB]

before building perfect squares and doing lots of maths, remember that unmodded inserters have only a reach of 1 or 2 tiles, and also can't reach diagonally. thus even on a small 3x3 square, no inserter will be able to insert fuel cells into the center reactor and you'll miss on all those nice neighbor bonuses as if that center reactor wouldn't exist. similar also applies to all other square or rectangle layouts which are wider than 2 reactors. even in the case of a small cross of 5 reactors, how would you feed the center one (that theoretically could get a bonus of +400%)? thus the practical limit is to have only 3 neighbours for any reactor, and as few corners as possible. there are mods for inserters with extra long reach of 4,7,11,..., especially created to fuel up reactors in such huge rectangle layouts, and several other mods for operating them diagonally, but no such luck in vanilla and you are limited by accessability of the reactors, resulting in the most simple version, having stripes of 2xN reactors, already giving all of the reactors (except for the four corners) the practical maximum bonus of +300%, and still the next best +200% bonus for those four corners. and even then it also already will be a challenge to make it tileable for larger values of N, and to feed it enough water while pipe throughput is limited to less than 1200 for longer pipes ...

[@DRY411S]

With a probability of 0.007 of getting the Uranium 235 you need to make reactor fuel cells, you should expect to have the U235 you need after 143 processing cycles. 143 cycles will take 143*10/0.75 seconds = 1907 seconds Put the U235 in an assembler and make 10 reactor fuel cells in 10 seconds => you have 10 reactor fuel cells in 1917 seconds Those fuel cells last 200 seconds each, 2000 seconds total. So a single centrifuge should be expected to produce fuel needed by a single nuclear reactor by the time it runs out of fuel. There's no need to panic and process huge amounts of ore. If you only burn the U235 into fuel cells when absolutely necessary, eventually you should expect to build up the surplus U235 that you need o start the Kovarex recycling process.

[@Xterminator]

I like the math! That's a really good point for sure. Although it's still cutting it pretty close, so personally I would still prefer to start mining as early as possible and save up the 40 to start the Kovarex Enrichment Process because then that can just snowball on itself.

[@DRY411S]

if you used 1 centrifuge to generate the 40 U235, it would take 76267 seconds or just over 21 hours. :)

[@toasterbot9597]

100 / 0.7 = 143 processing cycles. 100 / 0.007 ( the correct percentage ) = 14286 processing cycles

[@DRY411S]

Toasterbot959 143*0.7/100 = 1.001. The percentage is reported to be 0.7% which is 0.7/100. Multiply that by 143 and you get 1.001. If it's the number of cycles you suggest you're going to need 100 centrifuges per reactor.

[@toasterbot9597]

You are correct, my apologies. I saw the 0.007 on the wiki and confused it for the percentage.

[@Merssedes]

Turbine produces up to 5.82MW: steam at 500C, it's 485C above "normal" 15C; 485C*200W/C = 97kW per unit of steam, or 5.82MW per 60 units of steam

[@b0bsaget007]

Another useful ratio which I calculated is 29:116:200. That's the perfect ratio of active reactors to heat exchangers to steam turbines.

[@safrussalmus9056]

Daniel Senti You are forgetting neighbor bonuses on the reacters. an 4x2 reactor can support 112 heat exchangers, for example.

[@b0bsaget007]

Safrus Salmus I'm not forgetting that. You can count the 4x2 grid as 28 reactors (as mentioned in the video) and then add one standalone reactor to make 29.

[@JoopEee]

Those aren't exactly "perfect" ratios. Putting one reactor as standalone would be wasting, so of course we put it next to the others. But then it'll obviously count as 2, so the ratios change as well.

[@RetechDragonflame]

Very useful for designing your own reactor setup. One question though - if you have multiple reactors adjacent to each other to get the neighbour bonus do all reactors still need to be fueled or does only one need it? EDIT: Tested it myself already.The only thing that unfueled reactors do is convey heat (very expensive heat pipe)

[@PD-Pro-Go]

Solid video, well done mate :)

[@Gabriel4Drummer]

Best tutorial I’ve found :)

[@epicstyle1000]

reminds me of the old command and conquer games

[@bheilbut]

Hello X, recently I checked the forums and you can feed the heat exchangers from boilers powered by coal and the capacity of the water/steam stacks. So the 5.8MW per turbine gives some interesting/easy ratios. 1 water pump: realistically this is 1/2 a water pump 10 boilers (18 MW): output feed into the heat exchangers 4 heat exchangers (40 MW) : 1 effective reactor : multiple setups could be powered by reactors with a neighbor bonus. 10 turbines (58MW): 1:10:4:1:10 seems easier than the numbers given by Mad Zuri and it is 100% effective all the time. To me this seems to be much easier to remember and I can convert my old power setup to nuclear and only have to discard the steam engines. If you would like I could submit a blueprint string.

[@Xterminator]

Interesting. I didn't really consider the idea of mixing normal boilers into the setup. Based on your numbers it seems like it could work quite well! Personally, I would prefer to just keep my Nuclear setup with Nuclear parts and not mix stuff, but that is just me.

[@bheilbut]

It also takes a while for the reactors to warm up and is dependent on external power for the roboport and inserters for the reactors.

[@bheilbut]

Here is a 4 reactor setup. Could you feature this on the workshop? pastebin.com/cY3aV8AH

[@Quintingent]

Very nicely explained. While I haven't got nuclear power yet in my 0.15 world I have done a bit of research (not the in-game kind) into how it works and you covered it pretty thoroughly. One thing I think is worth mentioning is that the Heat Exchanger to Turbine ratio is very close to 4:7 (to compare the actual ratio is 60:103 whereas 4:7 is equivalent to 60:105). Not only is this essy to remember but since Exchangers will come in groups of 4 it's pretty convenient. Obviously in larger builds the discrepancy will mean having turbines that get no steam at all (about every 7 reactors' worth) but still useful for rough planning. I do have one question though. You mentioned the fluid rate from offshore pumps, but what about unbarrelling water or pumping from a train? As somebody whose most anticipated feature of 0.15 was the improved fluid handling (I can finally have the modular factory I've always wanted) I'm rather curious as to what it can achieve.

[@Xterminator]

Thank you! :) That is a good point about the 4:7 ratio. It's certainly easier to remember. Personally, I prefer to just use the 1:1.72 ratio because it allows me to calculate it out regardless of the size or layout. For your question I'm not sure I can really answer that fully unfortunately. I believe the pumps that you use to pump from a train have the same flow rate as an offshore pump. In regards to barreling and unbarring water, I suspect you would need an insane amount of machines doing it sense the exchangers use water so quick.

[@Anson_AKB]

just checked with the wiki: since version 0.16.8, barrels only hold 50 instead of 250 fluid, with a stacksize of 10 (time for barreling also was lowered from 1.0 to 0.2 to compensate). thus in the old version you would have been able to unbarrel a stack with 2500 fluid in 10 seconds, and now can unbarrel a stack with 250 fluid in one second, both values are much lower than the 1200 per second of pumps. loading and unloading with a pump directly between wagons and tanks is extremely fast (maybe 2 or 3 seconds only; similar like using inserters with stack bonus and transferring from chest to chest), but from that tank onwards, it would be the same as if you have an offshore pump, with all the limits of (long) pipes etc. maybe trains are useful to cut down on length of pipes when the next water is far away, but it probably will be no huge advantage. in the same version 0.16.8, also wagons were nerfed to have a single tank worth of fluids only, thus either 25k fluids in a fluid wagon or 20k fluids in barrels in a cargo wagon. to achieve the througput of pumps you need to handle one wagon per pipe in 20 seconds. for a small reactor setup which needs 4 pipes of water, you would need a 1-4 train every 20 seconds, or a 1-1 train every 5 seconds :-) ps: i have seen some similar setups in some video clips, transporting water from far away with 3-12 (or longer) trains and thus having more compact setups than using 12 parallel pipes, but it will be a challenge, especially when you would need to cross heatpipes and train tracks which isn't possible ...

[@x11tech45]

Thanks-- this improves my original ratio planning because of the wrinkle caused by the 'neighbor bonus'-- this also has me thinking about optimal layouts-- 1, 2, 4, 8, 28.

[@x11tech45]

steamcommunity.com/sharedfiles/filedetails/?id=917637096, steamcommunity.com/sharedfiles/filedetails/?id=917637154, steamcommunity.com/sharedfiles/filedetails/?id=917637212 -- been playing around with some designs based on your video. It appears that the ratio is 1:4 Reactors to Heat Exchangers-- but the ratio between Reactors and Steam Turbines varies based on actual layout. Science/tests suggest that your 1:6.88 ratio for Reactors to Steam Turbines only applies under certain layouts. So it seems it would be more accurate to say it's 1:4 (Reactors to Heat Exchangers) and 1:1.72 (Heat Exchangers to Steam Turbines)-- so if you connect Turbines in a 1:2 ratio your layout will always lose some efficiency and require a lot more Steam Turbines. If you connect them in sequence, then you may be able to maximize power output. But because of the oddities of heat loss through pipes (this can be seen, originally, with the original pre-0.15 boilers and steam engines) layouts involving pipes likely result in loss of stored energy during pipe-based transmission. So layouts involving pipe (to achieve any kind of OCD based design) are less efficient than just stringing them sequentially. Since heat conduits from Reactors seems to not suffer heat loss, I'm imagining some potential layouts that would minimize pipe usage and extend heat conduit very large distances to maximize efficiency and minimize construction costs for your reactor designs. More science is required.

[@x11tech45]

Experienced the bug you were talking about where heat does not transmit correctly through heat pipe by re-wiring a section of the heat pipe and then destroying the 'old path'-- some heat exchangers were not able to get > 500 C as a result of re-wriring, causing a loss in MW produced because the heat exchangers simply would not convert water to steam. This resulted in an output of 800 C (after a new warm-up cycle that lasted > 800 seconds.) Lesson learned: pre-plan everything, lay everything by hand. Like you said, hopefully the devs will improve the heat transmission algorithm so that layouts can be put down by bots without loss of effectiveness.

[@gnuthad]

I've used nuclear power previously but I didn't know that reactors could pass the heat through themselves. I've run reactors two wide (or high) and run a heatpipe off each of the long sides through to my power station.

[@CoolHillBillyGamers]

I just realized that the recycled fuel cells actually give the actual cost to make twice as much 235 than went in, meaning that you actually only need to input the iron and 19 238 for fuel and still be outputting 235 at the end of it

[@berenscott8999]

Yeah, the thing is, you really want your arrangements of reactors to be in a square shape to make the maximum utilisation. Which means you lose the ability to insert fuel into them and remove spend rods when you get a 3x3 setup or above. A 4x4 would be awesome. We really need the bots to be able to directly insert and remove from the reactors. Yes you could use a 2x(whatever) setup, but that gives you a maximum of 300%. A 4x4 setup would have the 4 reactors in the middle at 400%. Alternatively, we could use a 5x5 setup, leave the reactor in the middle empty, and use the adjustable inserters mod and logistics chests in that centre area, this would give you 24 reactors, 4 would be at 200%, 4 would be at 400% and the rest would be at 300%. That's (4x3)+(4x5)+(16x4)=12+20+64=96. 96 * 4 * 1.72 * 5800000 = 3,830,784,000 from a small 5x5-1 field. I've got some further questions. If a reactor has no fuel, will the neighbouring reactors get any bonus? Next, rather then toggling the fuel from the reactors, can we store the steam? Or use accumulators? I would imagine that the reactors would work better if the fuel were constantly in them rather then removal. I think a mod which allows neighbouring reactors to share fuel would work awesome.

[@Xterminator]

I agree, being able to make a square with them would be ideal. Without using mods, the best we can do now for that is manually insert the fuel every once in a while for the ones in the middle. For your questions: Nope, it won't get the neighbor bonus if it has no fuel unfortunately. Yes, you could store the steam and probably use accumulators. I suspect there might be some downsides to storing steam though. Would require more testing and time to actually figure it all out though. That would be a pretty cool mod too!

[@berenscott8999]

I could probably imagine people avoiding nuclear just because by the time they've unlocked it, they've already stamped down enough coal and solar. The sheer scale of the processing required to get it off the ground is large enough that you've already built a tonne of solar to support it. With coal being a better option then it was, do we really even need it? I can imagine that players may use it, but next to a giant accumulator field just to maximise the yield, and they may not plug it in until they had an absolute tonne of fuel for it and a huge reactor setup. Honestly, it may prove too expensive in the players time to bother with.

Build them in rows and you won't have much problem with spacing them. 10 times what you have there? Well, build 10 rows of the same setup, and it'll mesh nicely. Yes, it takes up space, but it's not that bad when you look at the finished product. Build it out of the way and you won't even notice it's there, in the grand scheme of things. To put in perspective, the 1990 minumum tiles that setup would take is dwarfed by for example solar. To get the same power output from solar panels (only counting the daytime, would be more for 24-hour operation) would be 18 560 solar panels.

[@BrianD0313]

For the Water Pumps, if you have two or more Water Pumps, can you connect their pipes or do the pipes have to remain separate? Thanks

[@25DizzyMan]

You don't need anything complicated to save the fuel cells. You can just hook up one of your capacitors, via circuit connection, to the arms that put in the fuel cells to your reactors. Set any letter or color as output on the capacitor, it will output this symbal corresponding to the % charge it has, so 100x when full, 0x when empty. Now set your arms to only work on the condition the output from the capacitor is equal or lower than X, 10 - 20% (still need to figure out how much margin is needed myself) :).

[@Xterminator]

Interesting, sounds pretty easy actually. I'll have to try it out myself sometime and see if I can get working without blowing up my factory. :P

[@25DizzyMan]

I tested a bit more, make sure not to request too much energy cells in your chest, your arm can input 3 at a time, which can be wasteful. Thinking more about it, as an extra backup, i believe you can store steam in storage tanks, with the turbines using 60/s and the tank holding 25000 you should be able to store about 7 minutes of steam per tank, per turbine. Man, this new nuclear implementation has my head spinning with ideas, loving it :D.

[@Xterminator]

yeah it's super cool and so many possibilities with it. :D Good point about the inserters inputting multiple at a time too, that is pretty wasteful.

[@jonilarsen-haikarainen8733]

I have tested, you can actually do 3x3 reactors. And the middle one will get 400% bonus. But without mods you will have to operate the middle one manually, inserting fule cells and removing old once.

[@Xterminator]

Yeah. In terms of neighbor bonus, doing a square is best, but you will have to insert manually like you said without a somewhat cheaty mod.

[@asghan]

What is the name of the mod used to generate the fluid here? Looking for that for quite some time now but couln't find it.

[@hansisbrucker813]

It can get crazy if you loop the output of the Kovarex process right back in

[@Xterminator]

Yeah definitely! Which I like.

[@possumridgeentertainment4614]

Latecomer here, but is there anything that absolutely requires nuclear power? I'm not really seeing any advantages over boilers, other than the possibility of replacing a long coal belt with significantly shorter fuel belt. But even that seems to be outweighed by all of the steps required to get nuclear fuel vs. mining out a coal field or bringing coal in by train or even upgrading to solid fuel.

[@Xterminator]

Possum Ridge Entertainment Basically it is far more space efficient and game performance efficient. because you can get way more power from it compared to steam. It also wouldn't need constant coal fed to it.

[@talltroll7092]

Yes, the effort is front loaded, but once you have it set up, it will produce all the power you will ever need, plus U-238 for upgraded ammo, plus excess U-235 for nukes, with very little pollution, and free your coal for industrial and transport use

[@Anson_AKB]

@@talltroll7092 there is also nuclear fuel for trains :-) but what about solar? isn't that OP too, when you only plop down a blueprint once ("front loading" it), let bots build it, and then never care again ?

[@lilfrostyy8829]

This video is a month old, but I did some math and found a ratio heat exchangers to turbines that comes out to all whole numbers 25 Exchangers : 43 Turbines = 0.58 1 : 1.72 = 0.58 If this is common knowledge by now.. it's whatever. Figured I'd put it out into the universe since with some algebra you could figure out reactors needed and pumps needed, and how much power it outputs.

[@Xterminator]

Nice that sounds about right! I don't think it's really common knowledge, so thanks for sharing. :)

[@newCoCoY6]

19:35 do we still need to do this walk around for heat pipes or is it fixed already?

[@Xterminator]

Edward Dizon It has has been fixed. :) However, heat pipes now lose heat over distance, so there is a max distance you can run them before they lose the heat required to heat the exchangers. A quick Google Search for something like "factorio max heat pipe length" should bring up some posts that give you the distance and such. :)

[@newCoCoY6]

Thanks for the reply :)

[@davidanalyst671]

Im trying to figure this nuke stuff out... I guess I'm going to have to watch a different vid. I need help specifically with refinement. why is there no setup to show the best way to do this?

[@omarcampeotto9545]

Per favore se puoi fare una lezione su funzionamento dei treni con i semafori e segnali a catena

[@inperangua]

I have a question. I wanted to do some laid back playthrough. Is there an easy way to create new ore patches in game? I couldn't find any 0.15 mods for that. Best approximation would be 0.14 quarries, but they are not updating for now

[@dantebroggi3734]

0.15 automatically generates uranium in older worlds when you load them after updating. FYI.

[@inperangua]

Alright, but now I'm just curious. Is there a nice way to generate new ore patches in-game? I was thinking about water-only map.

[@bagok701]

A nice way no, there is a set of lua procedures you can do, but those are difficult to type. Something can be modded in, I haven't looked yet but you might find something in the Factorio forums.

[@Planet-Anime]

So comfoozing

[@leavy]

it’s got nothing on the potential complexity of industrialcraft2 and nuclearcraft reactors from modded mc

[@Recon777x]

19:09 Has this bug ever been fixed where you have to lay down your heat pipes in a certain order?

[@_Some_Random_Dude]

Eh, by the time you set this up, you'll have gigawatts of solar power.

[@TheNefastor]

Yeah but I don't like solar, it takes too much space and it's boring AF. It's great for my home and my office, but not so much for my video games 😅

[@hoovyzepoot]

@@TheNefastor And plus, solar needs a metric shit ton of capacitors or a backup steam system early, and nuclear is better than solar in almost every way, including not producing any pollution

[@aisir3725]

But uranium ammo as a byproduct

[@Rodri9333]

what about speed modules on the centrifuge? Do productivity modules works?

[@Xterminator]

Productivity modules work with some of the processes, but not the Kovarex Enrichment one. Speed modules do work on all of it though.

[@Anson_AKB]

current state of affairs many versions later : because of the problems (possible exploits) with productivity being applied to all 41 uranium, those modules were first disabled completely, and then reenabled with the new "catalyst" mechanics where only the difference would get the bonus, thus when inserting 40 and 5, and getting 41 and 2, 40 and 2 would be considered to be only catalyst, and only the one new surplus uranium would get the bonus, which is a really small amount while also slowing down the process. using speed modules will get you many more cycles and thus much more of the valuable uranium in the same time.

[@ieaturanium574]

TL:DW does nuclear reactor generates the same pollution as boilers?

[@SerBallister]

None to little as far as i can see

[@AkiGames093]

I did everything but may steam turbines don't work. I have 4 heat exchanges at full capacity and 4 steam turbine

[@leerman22]

I got a 4x2 reactor setup going and it powers EVERYTHING. 1.1GW of power. I wonder if this string works for everyone.

[@Xterminator]

Very nice! :D The string should work for everyone yea.

[@peterknutsen3070]

Is it still possible to massively cheat with Productivity Modules, when refining Uranium, or has it been fixed?

[@Valkeyring]

It has been fixed :)

[@peterknutsen3070]

Goodforthewin Nice!

[@filmfilm86]

Great vid, thanks

[@Malfunct1onM1ke]

I just read on the forum that heat exchangers benefit from boiler-preheated water.... God Lord, what a setup this is becoming.

[@Xterminator]

I'm just finding this out now too. That certainly changes things up a bit. Will have to look into it more!

[@DanneManne88]

If i hava a older Save file, from older version, and uppgrade the game, can i faind Uranium then?

[@spinba11]

Daniel Johansson yes

[@MrSearker]

Yes, uranium can spawn in any newly generated chunks, so you´ll have to explore new areas.

[@jessekessler1201]

Patches will spawn in explored areas near the spawn as well, doesn't have to be new chunks

[@oblivion_2852]

Daniel Johansson They used retrogen so uranium isn't exclusive to new chunks

[@Flackon]

what's retrogen?

[@jakobpayne1]

What was the purple C creative mod? (Too lazy to check the mod portal)

[@Deilwynna]

[@mynamedontfi]

Nice vid thx

[@Xterminator]

Glad it helped!

[@nelsonmalbone]

What mod you using for the always day in night deal?

[@nelsonmalbone]

Thanks I found :)

[@jefkinbacca]

Nice! I'm about 1/2 way to nuclear on my first 0.15 ;D

[@Xterminator]

Awesome! Hope your already processing that Uranium to get the fancy stuff. :P

[@jefkinbacca]

Seems I'm only getting pumps to support about 8 or 9 heat exchangers instead of 11

[@Xterminator]

Do you have long pipe lengths between your pumps and heat exchangers?

[@tristanlievens5216]

What mod are you using for this sandbox? The features are amazing, especially the unlimited power drain and power source. Would be very useful for my own designing processes :)

[@Xterminator]

Using the Creative Mode mod. It is an amazing mod for testing stuff. :)

[@jhgastrich]

Why not a 3X3 (I would assume, given the bonus, t hat 9 would produce the same as 33)

[@Xterminator]

If you do 3x3 there will be some reactors where you can't insert/export fuel.

[@GretchenDawntreader]

nice nuclear intro, I just wonder how much it's changed in 5 years.

[@Gill2cyclpos]

nuklear power. with mining productive seems extremely good

[@Xterminator]

Yeah, the mining productivity probably helps a lot with the Uranium mining.

[@Gill2cyclpos]

Xterminator it seems that it was disgened to go that way because of the rarity in uranium pieces

[@gunfire123nate8]

I got 18 nuclear reactors and i only have the tech for nukelear power you can run it you juat need a good uranium source

[@claytonmcgough5991]

I used the exact setup but the performance is at 1. Everything looks to be right, except it says fluid consumption is low, even though steam is at max

[@Xterminator]

Kind of sounds like you aren't using much power so it isn't working very much at the moment.

[@claytonmcgough5991]

Xterminator Ok Ill try to increase consumption

[@tinatpasselepoivre]

Does productivity module work? (for the centrifuge)

[@FF177-]

tinatpasselepoivre Only for the first step of refining, they fixed enriching with productivity giving you the catalyst back very quickly

[@vovozaum]

16:20 i know this is an old vídeo... but why would you waste só much potential energy just because a pump cant provide for the 16 heat Exchangers that you need to build???? Pumps are basically free... You could put 16 pumps for the 16 Exchangers and it would not make a difference.... wasting almost 25% of the energy production just because you didn't use 2 pumps is absolutely crazy... whyyy???? Whyyyyyyy?

[@waverlyseptember4891]

Isn't it 5.7 thousand rather than 57 thousand ore to get 40? Because the calculation should be 40/0.007, which comes up with about 5.7 thousand.

[@Xterminator]

That is 5.7 thousand cycles, but remember each cycle takes 10 Uranium ore.

[@felipemarques3585]

WHY DO NOT YOU MAKE A VIDEO OF HOW TO USE THE NEW CISTERN WAGON?

[@iNezerroth]

0.7% is not 57k, it's 40/0.007=5714. Which is 5714\0.26=21976 seconds from single unmodded drill, divide it by number of drills, speed (or preferrably productivity modules) and mining productivity upgrade, you'll get 40 in like 10-20 minutes tops.

[@Anson_AKB]

you forgot that the recipe uses 10 ore per cycle

[@TirehtooriRIP]

hmm so basicly you can Endlesly Generate more "235" by just Cycleing it around and around, well not endlesly but the lesser one trade of

[@AdamWebb1982]

Newbe comment here but how do you get those red chests (that allow you to spawn Acid etc) and red accumulators?

[@BearMeOut]

downloaded mod from the deep web

[@Xterminator]

It's the Creative Mode mod. :)

[@AdamWebb1982]

Cheers both of you. Seems a good way to "test" and learn new factorio systems.
