Improved Vacuum Reactor | 5A IV in EV | 3x3x6 with no heat gain

[crisp tusk]

based on ivelieu's design, had another reactor fill with cooland / spontaniously explode so went from this(which was already modified a bit after some explosions) To this today . will post in a couple of days if it manadged to not blow itself up with a more detailed overview since i can't currently say its error proof.

[crisp tusk]

Its been fully cycling correctly even with the aquard 1tick between multiple sets of rods when switching out those rods & coolant swaps happening in between that so here's the fully documented AE2 vac nuke improved design inspired by Ivelieu's original AE2 design.

[mortal gazelle]

i'll take a look at this later i'm quite interested in this design

[crisp tusk]

Nothing was wrong. Deleted messages I was just beeing dumb 😆

[sterile garnet]

Switching over didn't work

[crisp tusk]

@sterile garnet I assume with 100% uptime your only shutting of your reactor when you have enough power? and swapping while its active? or does it still shut off to swap?

[sterile garnet]

Shutoff for power and fuel swap

[sterile garnet]

it coolant swaps properly, I watched it do a fuel swap properly, the server doesn't do restarts. I must be missing some sort of edge case.

The most recent explosion/shutdown had extracted fuel still in the extract fuel cell, inside of the io port that is supposed to send it to the disposal network.

somehow it got stuck in that state.

[crisp tusk]

The reason for my locking of the fuel / coolant swaps was because when these 2 overlapped on a 1 tick difference issues arose and depending on which one was first it was either reactor full of cooland or full of rods where the one full of rods somehow blows

[sterile garnet]

coolant is also locked during fuel swap

[crisp tusk]

hmm yeah so that can't be it in your case

Could it just be an unlucky cycle timing ? where you gain heat midway through a coolant swap ?

( coolant extract ) -> Reactor tick -> Boom / ( Coolant insert )

[sterile garnet]

it's possible, but that's implying the design I have is wrong. Which just loops back to why is the design wrong.

[crisp tusk]

its the issue i guess with keeping your reactor running while coolant swap is occuring

[sterile garnet]

it's supposed to not be possible with the correct design, because starting the coolant swap timer at the correct time prevents overlapping nuke checks

[crisp tusk]

yeah but thats if you know when that tick happens exactly

and presumably that tick changes with server restarts

[sterile garnet]

I was under the impression the tick starts when you start the reactor.

[crisp tusk]

I dont think so cause sometimes a reactor takes a while before it actually starts

and sometimes it insta starts

so to mee that sounds like its on some shared global tick

[sterile garnet]

otherwise you'd be gambling on a 1/20 roll every time you restart your coolant timer.

[crisp tusk]

in my case the reactor is down for 32 + 8 ticks at a minimum

so thats ample time to swap if the tick is 1/20

i can probably reduce it to 16 + 8 tbf

[sterile garnet]

Are you doing reactor off coolant swaps?

I was thinking about it, and I remembered why the reactor tick can't happen during a coolant swap (in theory). The coolant cells only heat up after a reactor tick, and the swap only happens at a specific heat, every 500ms. So, the swap would always start after the reactor tick occurred, with plenty of time before the next reactor tick.

At least, that's my understanding.

[dense bloom]

Yeah there should be no inherent problems with the 100% up time design

[sterile garnet]

I wish ic2 nukes went into the explosions log with timestamps so I could cross reference to see if it's server lag related.

[crisp tusk]

what if you set it to something like 250 ms (5t) cause if your timer takes a tick to disable (idk) starts a 10 tick time sends signal and then still needs 1 - 3 ticks for the full coolant swap perhaps there is a way for the timer to start later than expected and exactly hit the heat tick rarely ?

[sterile garnet]

I don't think changing the timer rate would fix it, but you did make me think of something. Say the cooler swap gets paused right after a reactor tick where a coolant drops <25%. Then, some arbitrary time later, the timer starts back up. The guarantee that a swap happens after a reactor tick occurs no longer holds. It could now theoretically occur on the same tick.

So, whenever I turn off the coolant timer, I should do one last swap as a precaution. (Assuming the reactor also turns off)

[crisp tusk]

made a small modification on the circuit on the bottom right. the receiver -> not gate was making it a 50 50 chance the rs latch toggled back into the correct state. this didn't cause any issues for me while running it just made rod swaps sometimes take longer than intendeded. to fix this i just rotated the timer and pulled the signal into the RS latch making sure to insulate the signal with strips.

(The other modification you can see above the fuel AND gate is an inverse of the force shutdown. this was so I could heat up new reactors that were already connected to the reactor network without them getting flooded with rods from fuel swap . )

[dense bloom]

that is also something I figured I should do after having problems with my circuit

used an 8 tick repeater and pulse former

[sterile garnet]

I saw and took inspiration from that

[dense bloom]

I don't quite understand how the original design doesn't need it tbh lol

[sterile garnet]

well, we'll see if it helps my reactors. If all my nukes are still there in the morning, ill feel pretty confident.

they did not make it to morning

[dense bloom]

damn

[crisp tusk]

i had a thought. since coolant swap is the most important thing here right. and you want it to always swap every 500 ticks after your reactors restart. wouldnt it make more sense to use an RS latch too toggle the timer on and off. you toggle it off when reactor is off, and you toggle it on when the reactor is on. then you use the timer signal to toggle an RS latch that blocks the fuel swap to make sure you prioritze the coolant swap when it needs to happen. and only allow fuel swaps when no coolant swap is happnening.
Thoughts?

[sterile garnet]

I'm still not convinced coolant swap is even the problem, so I'm not sure

[crisp tusk]

how else would it gain heat ?

[sterile garnet]

No idea, otherwise I'd be looking into it

[dense bloom]

Fuel swap is theoretically not possible during a coolant swap bc it’s delayed by 16 ticks compared to coolant swap’s 8

By the time fuel swap happens the coolant swap should have been turned off by then

This delay system works fine as far as I can tell

[sterile garnet]

I have a sneaking suspicion it's somehow lag related, even though the server is generally fine.

[sterile garnet]

Might need to give up the 99% heat nukes dream. No change i make seems to have any impact on preventing an explosion.

[crisp tusk]

I'll mess around with a non disabling reactor design soon. but yeah it seems allot more complicated 100% uptime at 99% heat

[worthy finch]

@crisp tusk im not really following this thread any more but it looks like reinventing the wheel, this 100% design is super reliable, did you try it

[crisp tusk]

Yes. Even a friend on another server followed it and every 2 or so days messed up

We'd end up getting 1 reactor full of coolant and it stops. or they just blow up.

I ran it in singleplayer for a week and it never messed up so i presume it is some server jank

[worthy finch]

did you exactly copy it

[crisp tusk]

Originally yes. After it messing up 5 times i started modifying it

[worthy finch]

i thought it was really simple.. maybe I should have done a world download after all...

[crisp tusk]

when i originally coppied it it was only running on 2 - 6 reactors with mox

[crisp tusk]

There is a world download

[worthy finch]

No

[crisp tusk]

One of your videos has a world download with it in it

[worthy finch]

And I am not talking about that

[crisp tusk]

oh wait I did not see that that you just referenced

I should have scrolled up the thread more my bad

I'll try this with the core once I Make them 👍

[worthy finch]

it works with all fuel

[mortal gazelle]

althought nukes are past me at this point of the run i might need to try that setup to sanity test the problems i used to have as well

[sterile garnet]

I have a lead into my (new) issue. Question for anyone who runs reactors with constant coolant swapping: are you using hyper-acceleration cards? If not, how many reactors do you have and how many coolant cells do you have in your insert cell?

Because using ivelieu's most recent setup image, I managed to catch a reactor getting excess fuel cells put in during a coolant swap, causing a heat increase.

[worthy finch]

base io port speed is 256/tick, you should have enough coolant in buffer for a bit over one full swap of all reactors to work with the coolant lock, you dont need acceleration cards unless you have more than 6 nukes

[sterile garnet]

Is the 256/tick based on the cell contents, or based on what needs to actually be transferred?

[worthy finch]

max transfer rate is 256 items per tick

https://github.com/GTNewHorizons/Applied-Energistics-2-Unofficial/blob/af81388a3e2729ff2c3eacffb18aa3d076ebed02/src/main/java/appeng/tile/storage/TileIOPort.java#L303

[sterile garnet]

ok, so IO port is only throttled by the actual transfer, it doesn't matter if the cell itself has a lot of coolant that isn't being inserted.

That makes that lead dead.

[sterile garnet]

Something is definitely causing my coolant loop to happen on a reactor tick or something. I setup a few 0 heat test reactors, and one of them gained heat and stopped after having a new coolant cell inserted.

[sterile garnet]

Ignore my last 5 messages, my setup was wrong. Here's to praying this will actually fix my issue

[dense bloom]

what was wrong lol

[sterile garnet]

This isn't what was originally wrong, but when I switched to Ive's most recent image, I had coolant inserting before extracting.

because I changed the direction the signal came from

and yet, still, the coolant swap is leading to heat increase.... hmmm

[sterile garnet]

I would like to thank all of the active and passive participants in my yapping over the last few days. After switching to the setup in Ive's most recent image, my nukes have survived nearly 24 hours, and I have high hopes for them to continue to work.

[crisp tusk]

@worthy finch how do you stop the reactors from blowing when server restarts and the reactor was on when the restart happened ? ( / when it crashes ). I have tried this in singleplayer and got a setup now that can sometimes survive a restart but not consistently. or is the consensus just be on a server that never restarts ?

[mortal gazelle]

on single player turn the reactor before logging off (scuffed but works), on a server you control just don't turn it off or do the same thing as the single player world, on a server you don't control but with programmed maintenance you can try playing around with it, server you don't control with random restarts i'm pretty sure you're shit out of luck

[crisp tusk]

Me and Potato were messing around with the idea of using ME level emitters which works to a certain extent

but it seems like theres a 1 specific tick edge case always where your just out of luck

[mortal gazelle]

level emitter for checking if the network is on before allowing the signal for the reactors?

[crisp tusk]

yeah for both reactor and the initial control circuit

since a level emitter with fuzzy card and number >= 1 is offline on a server restart / relog

but i believe because some of the project red bollux stays on from the save ( same with redstone p2p ) its not as clean as youd wish itd be xd

[sterile garnet]

Ivelieu mentioned using an AND gate with level emitter + redstone p2p input on the reactor. It's what I do, but I'm not sure how guaranteed it is on restarts.

[crisp tusk]

I mean without server restarts the coolant swap is so mind numbingly simple its hilarious

I just got 10 restarts without it blowing up only 1 the core reactor tho. so leme make a few more ( update: Reactor 4 blew )

[crisp tusk]

45 restarts. zero blowouts but im eepy now. Will set up tomorow on a server and see what that gives. ( 3 chamber reactors cause doing diffrent pattern now from max rod -> coolant pattern to see if that affects blow up chance on restart which it seems it does )

bottom left timer circuit is just me simulating a battery on / off

God is actually against me

[worthy finch]

its guaranteed, with a 50% or 75% fuzzy cutoff its completely safe on the core

[cursive crater]

ivelieu, since you said maybe I should have done a world download after all... im gonna assume you no longer have the world and/or the setup built in the world but ill ask just incase, do you still have it and if you do, can you provide it if its not too much trouble?

[worthy finch]

everything is in the 3 pictures quoted above

[cursive crater]

alright

[last orchid]

On 1080k cells?

[worthy finch]

on 360k

[last orchid]

Wait the core doesn’t one tick melt them?

[worthy finch]

scroll up like 50 messages and you'll see an example

[last orchid]

That’s actually sick then

That means there is actually working alternative for sfm

[tough halo]

Currently trying to copy this setup and i have a few questions. Do you remember what emitters were set to and what was the setting on the timer?

Have been trying to copy the logic but without success

[worthy finch]

500ms, 1, 14*reactors*2

[tough halo]

coolant swap works for the first few times but after a certain amount of restarts the circuit desyncs from the reactors and they all blow up

[worthy finch]

What

thats what the coolant shutoff is for

[tough halo]

I just looked at this again and the red circle is the coolant shutoff? If yes then what are those emitters set to?

[worthy finch]

.

[mellow turtle]

it doesn't no

[worthy finch]

The fuel one is to check enough fuel

[tough halo]

Copied the whole circuit but instructions are still unclear. What are the settings for the emitters in the second picture? 3rd and 4th picture are my current settings. I have just been playing with those two emitters to see which configuration works but no luck. What am i missing? Fuzzy?

[worthy finch]

Didn't you watch the videos or anything, it was covered there.

[stray laurel]

Hey Ivelieu. I'm trying to recreate your reactor design and have a few questions.
Does fuel get inserted in / extracted to main net through the storage bus on the right?
How is coolant moving from blue net to green net? I don't see any connection unlike the design on your last video.
Perhaps you have a world download for the new design?

[tight bane]

in the tutorial im a little bit confused, the wireless receivers/transmitters have the same power value but different names. I cant do that as when you set it to the same value as a previous one it just takes that name, is it important that they have different names?

[tawny parrot]

As long as the correct transmitter is outputting to the correct receiver it should be good. The names are just for organization, the ID is what connects the transmitter/receiver

[tight bane]

kk thanks man, im getting close to having it done

thanks so much for the in depth tutorial

[tight bane]

ive reloaded 4 times now
not sure what im doing wrong but this is ending up a nightmare instead of a dream

might have to do fluid nukes because they are way simpler and mine never blew up in my face

[tawny parrot]

Hard to say without any details, but fluid nukes might be an easier option if you don’t feel like figuring this out

[tight bane]

I’m not even sure what was wrong tbh
The lever on the nuke didn’t turn it off

I’m exhausted from it so I might give it another shot tonight

[tawny parrot]

The lever on the nuke is a manual turn-on. When the nuke gets redstone power it turns on

[tight bane]

The manual override didn’t shut it off either

[tawny parrot]

Must be something wrong with your circuit. Maybe if you sent a picture I could trouble shoot it a little

[tight bane]

I tore it down before it could blow up the last time I tried

When I try it again later I’ll let you know
I really do want the vac nuke because it’s so much more power than a fluid

I think my fluid nuke did like 6A EV and took up so much more space than this setup

[tight bane]

looks right compared to the top picture to me @tawny parrot you see anything wrong?

i havent fired it up yet, kinda scared to

i fired it up, i can power it down manually when i want so its going better

[tight bane]

its working pretty well, I forgot to change which way the battery buffer was facing so the vac freezer didnt have power. it stayed off and didnt blow up which was awesome but now the core temp is at 36% and it wont turn back on. How do i get the core temp back down?

i can manualy turn it back on but im worried about the core temp hanging out around 36%

[tawny parrot]

To get the core temp down manually replace some items with overclocked heat vents. That will reduce core temp. Once you are back at 0 replace the heat vents with the regular components

[tight bane]

ahh ty man
and what about the information panel? i tried right clicking the reactor sensor card and the energy sensor card on the reactor and it didnt grab the location. The only tutorial i could find said thats what i do

[tight bane]

I did measure it out at 21A of EV through 2 EV buffers which is amazing, im glad i followed through

[maiden yarrow]

Doing my best to read through the thread but I haven't seen this asked: Why the speed downgrade on the conduit? Don't you want the extraction and input of coolant to be faster? is it to limit it to 1 item?

[drifting ivy]

i assume its for protection against syncing up the coolants

so you dont gain heat, like an extra precaution

[maiden yarrow]

that makes sense.

[mellow turtle]

honestly i'd say use the io port setup instead at this point tbh

[maiden yarrow]

the AE2 design seems unreliable

[mellow turtle]

the non 100% uptime setup is very reliable

[maiden yarrow]

if you had a server with 100% uptime, sure

which is that?

[drifting ivy]

his original design works great, 21A of EV for basically free, ive had it running for a few hours with no issues

[mellow turtle]

it's only the 100% uptime setup that is unreliable

[mellow turtle]

there are 2 setups with io ports

one that will shutdown the reactor on coolant swap

[maiden yarrow]

this thread is so confusing.

[mellow turtle]

and one that won't

the one that won't is call the 100% uptime setup

[drifting ivy]

ive gotten this from someone i asked about the original non-100% uptime one

[mellow turtle]

because it never shuts off the reactors

[maiden yarrow]

I dont see whats wrong with isoarcrees design

[mellow turtle]

the timings can't overlap if you set up the repeaters properly

unless your server decides to die and skip a billion ticks

which at that point -->

[maiden yarrow]

im on single player

[drifting ivy]

🤷‍♂️ original design works well enough so

[mellow turtle]

i've had heat gains with iso's setup

multiple times

tbh

the io port design never failed me unless I made a stupid mistake

[maiden yarrow]

AE2 is so unreliable though

[mellow turtle]

AE2 is the most reliable mod for logistics

[drifting ivy]

different strokes for different folks

[maiden yarrow]

for single player with restarts?

[mellow turtle]

yes if you're not doing a 100% uptime setup even with restarts it'll be fine because it uses its own network

which should be small enough that the network update time will be negligible

[maiden yarrow]

so the ivelieu design here is what you mean. https://www.youtube.com/watch?v=geNquUY5J4g

[mellow turtle]

yes

there's also a google doc I wrote which is still correct

and technically more up to date about this specific setup

[tight bane]

if you add in the extra repeater at 128 ticks youre good on heat gain with the original design

[dense bloom]

Tbh I had a couple issues with random heat gain and coolant being inserted instead of fuel rods with isoarcrees design that I never was able to debug

It was infrequent enough that I just dealt with it until building the 100% uptime set up for the core

[safe pawn]

Is this doc linked somewhere? Would love to see it

[mellow turtle]

https://docs.google.com/document/d/1axuVkoBlBQYoNtDq2qvyu8FHBMOpc_YfNlucXJdWCDQ/edit?tab=t.0

[tight bane]

did you set this up? the tutorial kinda leaves a bit to be desired in terms of setup and explanation

[maiden yarrow]

No, I may do it if I do another run at some point, I opted to scale my nitro. I wasn't confident it would cope with my single player restarts.

[tight bane]

dang, im looking through the spreadsheet. hopefully i understand that a bit better

the video just shows, hey i have these things set up and doesnt say what some of the redstone pieces are and i dont know what im doing when it comes to project redstone

[maiden yarrow]

FcNobo + ivelieus video is a solid explanation. I'll try it for sure eventually. Yeah there is some assumption of knowledge involved.

[tight bane]

im going through the ivelieus video and its tough to follow

im clueless about redstone stuff

[maiden yarrow]

you need a solid understanding of circuit design, yeah

[tight bane]

i got isoarcees built with a bit of trouble but i upgraded to a platinum cable and my circuit blew up

this has me wanting to set up fluid nukes again

[maiden yarrow]

If I didn't have nitro already rolling, id do the Ivelieu iteration with normal enriched uranium.

just keep it all in the same chunk

[tight bane]

yea i built a 1 chunk building that should hopefully fit 6 reactors and the LSC above it

[tawny parrot]

EV cables are best for extracting power out of my design. Not sure what would cause an explosion just for switching to platinum though. Although honestly I wouldn’t recommend vac nukes in general if you don’t have access to back ups, unless you know exactly what you are doing

[tight bane]

i do have backups thankfully

i was going to try out some higher output fuel rods and the steel cables wont hold enough if i go higher than uranium so the platinum cables were supposed to fix that haha

[tawny parrot]

Ahh, I haven’t done any testing with higher output fuels, but they would cause problems unless you make changes to account for them

[tight bane]

yea i still dont really know what happened because the server crashed as soon as i put the cables down

[tawny parrot]

Well it would be extracting out at IV instead, so if you have it hooked up go an EV energy hatch or battery buffer then it would go boom

[tight bane]

i dont think i had time to do that, it was really quick

and the bat buffer was touching the freezer, that didnt explode

[tawny parrot]

Hard to say without seeing the setup. My only other thought is the reactor was being powered somehow and just happened to explode when you placed the cable

[tight bane]

im gonna try the ae one for now and try to figure out what the blocks hes placing down are

yours worked really well for me and got me through EV, didnt take many fuel rods either

ran a quad EBF and vac freezer on it making all my tungsten

[dense widget]

Great setup. We built the first one and it works pretty well, I was just wondering how I would wire this up to extract energy from more than one reactor ? One Battery buffer for each reactor?

[crisp tusk]

You would want to invest into an LSC ( lapotronic supercapacitor ) which controls all your reactors on and off depending on energy detector cover. that LSC then becomes your main power spine where all your power generation comes in.

[eternal bramble]

i make it but i hace heat in the reactor

i look at it and it seem that it turn it on when it's changing coolant

[tight bane]

I ended up adding a second repeater and changing the timer to 45s to resolve that issue

[eternal bramble]

can you show me? im too stupid

[tight bane]

Unfortunately I tried to upgrade the cable off the nuke to IV and my circuit blew 😦

The extra repeater I added was taking the place of the transmitter to the right of the remote comparator

Think I put it on 32

And the transmitter went behind it

[tawny parrot]

Not sure if this is the issue, but you should put a repeater between the 4 receiver and that the rest of the circuit. Set the repeater for 128 ticks

[eternal bramble]

like this?

but this is the power control that shut down the reactor when the energy got at 90%

[tawny parrot]

Yes. If the power control flickers on and off too much, it can cause the circuit to fail

This repeater fixes that

[eternal bramble]

ohh,

ok, but i don't have the lsc control at the time that the reactor have the temperature problem

D:

[tawny parrot]

Something must be wrong with the circuit if the reactor is on while coolant is being changed then.

[tawny parrot]

Idk man. The circuit is built to shut down above 5% heat. You must have had something very wrong

[eternal bramble]

ok with the new one

now it works idk why

[dense bloom]

Well you did completely change the circuit design lol

[sly stream]

It explodes frequently, but I don't know why

[mellow turtle]

what setup ?

[sly stream]

@mellow turtle

https://i.imgur.com/Ulb6Pus.png

mox fuel reactor * 64

Is there a problem??

[mellow turtle]

I don't see one but idk, the 100% uptime setup has been unstable to me tbh

[sly stream]

Would it be better to dismantle the 100% uptime setup?

[tidal valve]

does this work in 2.7.2?

[ancient shell]

How often will I need to make uranium mining trips for a single one? Never made a reactor and wondering whether I should ditch benzene for this

[dense widget]

if you go with mox and a staballoy construct EEC then you don't need to mine at all besides the initial plutonium investment

[maiden yarrow]

realistically you should have t3 rocket or meteor before you try to do mox, although its technically possible to centrifuge enough 239

just a long wait.

normal 40 rod quad uranium is still 43k eu/t

[errant cloud]

I count about 900-1k Uranium 238 for the initial fuel

You get 2/3rds of the 238 back when recycled

Ideally you’re mining from either Phobos or Deimos for pure Uranium ore

[errant cloud]

Old message but I built this sometime ago and the reactor finished one cycle with no issue. So I can confirm it works in 2.7.3

I advise against ditching your current power gen. I run a reactor along with my CBD engines currently.

I definitely can see myself relying on Bac Nukes alone when I have full ore processing

And I would like to to make the change to HOG now that I’m not reliant on Oil

[maiden yarrow]

once you have an LSC, power options are wide open

[ancient shell]

I've worded it wrongly tbh, let's say I went to Deimos, mined a single uranium vein, got back and got the reactor up and running. How long will it take for me to get thru all this uranium I've mined till I'll need to make another mining trip? Will I need to be constantly checking and making sure I'm not running out?

[errant cloud]

About 10 hours assuming full time

It took me ~a week to burn the initial fuel when I built it

Also automated the fuel with a subnet and level maintainer

[tawny parrot]

One set of uranium fuel rods runs for about 11 hours. Now how many fuel rods you can craft with one vein, I’m not sure. Depends on your miner and how big the vein is I suppose? It’s been a while since I was at this point, but I was semi consistently mining uranium and never got close to running out

[eternal bramble]

You need 40 quad uranium cells per reactor and 14 360k coolant cells

[maiden yarrow]

Although, the coolant cells are a one time cost per reactor. Also, you will want more than 14 because you need a buffer.

[errant cloud]

That and as I mentioned earlier, you get 2/3rds of the Uranium 238 back

[maiden yarrow]

Once you get rolling with the setup, its very efficient.

[ancient shell]

Can I use 360k sodium potassium rather than helium cells?

[errant cloud]

Helium is easier to gather

At least if you got passive Endstone

[maiden yarrow]

I dont see why not. I have unlimited sodium potassium for sure, just never tried it...

[ancient shell]

NaK is faster and easier for me, that is not my concern tho

[errant cloud]

You actually need Rock salt for NaK

Not elemental Potassium

But I think they have the same heat capacity

So just pick which one is easier

[ancient shell]

Can I somehow use existing control circuit and add another reactor to the setup? Or 1 reactor = 1 control circuit?

[errant cloud]

Depending on which part of the circuit

There’s a shared receiver for LSC power to toggle on power level

And I have a manual override lever for all reactors

But you definitely should apply a separate gate (emitter and receiver) for fuel, temp and maintenance check.

[stone sundial]

Is one freezer for one reactor needed or can make one freezer for two or three reactors?

[errant cloud]

I can see one having one freezer with how often it cools

But likely ideal to have one per reactor.

[tawny parrot]

You could have one freezer for multiple reactors, you just have to make sure that the coolant outputted is being disturbed evenly, and that the freezer is able to keep up with the demand of freezing everything.

[stone sundial]

And is 100% safe?

[tawny parrot]

Provided it’s built correctly and there’s no outside interference.

[stone sundial]

Perfect and I still have two questions? Do they have to be in a room with warded glass? and does this reactor also work with MOX rods safe?

[tawny parrot]

It’s not required to have explosion protection. But if you do something wrong, and it blows up, AND you don’t have access to back-ups. Well, just don’t say I didn’t warn you

Also, MOX doesn’t work right out the gate. I believe MOX has 2x heat generation, which means you’ll need to adjust how powerful your freezer is and the timing on how long you go before switching out coolant, which will slightly reduce your uptime as well

[stone sundial]

Aa ok warded glass is nuke safe 🙂

[stone sundial]

Why don't I get a redstone signal :c

[tawny parrot]

I think the remote comparator has a 16 block limit. You can get around this by placing it closer and hooking up another wireless

Where did you place your Redstone circuit?

As Isoarcree said, there's a range limit on the remote comparator.

[stone sundial]

hmm im build this setup 1:1.. and the reactor prodc heat....

[stone sundial]

you a answer of this?

[tawny parrot]

It’s likely not built correctly. There are lots of very finicky details that are very important when setting this up.
Right off the bat, I can see you didn’t offset your coolants, are you sure you built it 1:1?
Aside from that it’s impossible to say what else might be wrong without more details

[steady pollen]

Is there a button on mobile to scroll to top of threads In disc.

[vivid junco]

okay my reactor is gaining heat, but after a while (5 days or so) of running

im almost certain i built it right

it gained 5% heat

this is the inside of the reactor

[errant cloud]

I can attest that I built the reactor 1:1 carefully in both a creative and my world and I had no heat gain.

[wide shore]

do you have the extra repeater from the power control receiver

That fixed the heat gain I was getting

[tawny parrot]

^^^ this. Make sure you have the extra repeater between your “Need Power” receiver and circuit that was left out of the video. It’s described in the comment section

[vivid junco]

oh, i figured since i used an RS latch on the power detector it wouldnt be an issue

if it comes up again ill do that

[errant cloud]

Was it the repeater that you clarified what was the actual delay? I need to double check both the comment and my redstone circuit. I have no heat gain as of now but there might be a likely chance for such if I have yet to make the extra measure clarified.

[tawny parrot]

The important one is the repeater between the redstone line that indicates you need power and the circuit. Setting it to 128 ticks is enough to prevent that line from flickering which can cause issues

[errant cloud]

In that case, I likely won’t need that line due to having a RS Latch system on the LSC. Meaning it’ll only turn on and off at designated power thresholds.

[vivid junco]

i thought the same

but i still had heat issues (although they took a very long time to show up) and i havent had them since adding the repeater

[errant cloud]

I see, will proceed to add the extra repeater for the edge case.

[vivid junco]

added the repeater a while ago, just had heat jump to 8

[errant cloud]

I see this is an annoying edgecase we do not know the cause of.

I went through my 2nd cycle and still no heat.

[vivid junco]

okay, heat jumped again overnight

so maybe i did something? since it wasnt happening and then happened twice so close to each other

is it a bad idea, as a temporary fix, to add a reactor heat vent in place of one of the fuel rods?

that way when it does this it will automatically cool down instead of needing me to intervene

at the sacrifice of a bit of EU

fwiw it seems like some of my 'matching' (diagonally symmetric) coolant cells are always aligned when this happens

[vivid junco]

oh, but i guess itll just shut down before that can happen

i think my supply of spare coolant cells keeps going down...?

[eternal bramble]

im using this set up in server and i have 0 heat:
https://www.youtube.com/watch?v=N4iO1HlFvVQ&

[vivid junco]

might switch to that if this doesnt fix the issue or when i scale up

[vivid junco]

@tawny parrot if youre trying to find the issue, this might help: every time the core gains heat, i seem to lose a coolant cell

the vac freezer doesnt shut off so its not the vac voiding it

[tawny parrot]

Sounds like your timer might be off. What is your timer set to and what cells are you using

You could try shortening the timer a bit and see if you gain any more heat

[vivid junco]

55 seconds, but yea it doesnt seem to be rotating?

how do i turn it on then...

[vivid junco]

@tawny parrot ?

sorry

[tawny parrot]

It will only be rotating while the reactor is turned on. Try shortening the delay to 50 seconds and see

[vivid junco]

did this

still getting cells lost and temp going up slowly

about 1.5 cells per day

is it just that the time between power control being set to on and back to off is <50s?

do i just need a bigger LSC

[errant cloud]

How big is your LSC currently?

I had 9 EV Capacitors shortly after building the reactor.

[vivid junco]

5 EV caps

minimum

[errant cloud]

This has been a serious head scratcher for me. I can't think of anything you did wrong and yet you still get heat issues, whilst I don't.

[tawny parrot]

Yeah it’s really hard to tell what could be going wrong without having your set up in front of me to investigate unfortunately

[vivid junco]

i can see if the server owner could send you the dim file

would that be helpful?

[tawny parrot]

Possibly. If I get the chance to look at it

[vivid junco]

yea no pressure at all, ill see if i can get it

before doing that im gonna upgrade to 9 EV caps and see if that works

[errant cloud]

Maybe sharing screenshots can help? But that would mean we can't get a closer look.

[vivid junco]

ill send more info to troubleshoot if the problem persists

no issues since the LSC upgrade

[vivid junco]

okay it did happen even after the LSC upgrade

[vivid junco]

i can hop in vc (no mic) to screen share if anyone gets the chance

[vivid junco]

i should mention that i havent had an issue in 3 days

unsure why that is

or 1.5 dys ig

[vivid junco]

since this

[vivid junco]

oh, and it just happened

maybe if i just upgrade the LSC again itll stop

[wide shore]

i dont think thats the problem

[vivid junco]

is one IV vac enough for 4 uranium vac nukes with a sufficient (20 cell) buffer?

also, looking at this circuit from ivelieu's setup, whats to stop the fuel rods being reinserted while some of the cells are missing?

if you get really unlucky

do you just need to have a buffer thats twice as many cells as are in the nukes?

[mortal gazelle]

You should always have a larger buffer and usually you have a control mechanism to disable the reactor in case you drop below those levels

[vivid junco]

how large of a buffer

[mortal gazelle]

usually twice the amount you can hold on your reactors

so if you have 80 coolant cells total that fit on your reactors

you want a total of 160 coolant cells in the system

[vivid junco]

okay so i made iveleius setup but it somehow managed already to void my 15 cell buffer

wait

nvm

[maiden yarrow]

yes. (assuming 360k cells)

[foggy zenith]

having trouble w the 99% heat design w 8 mox reactors, is there some quirk to the way nukes provide power? cuz i should be getting like 900k eu/t but im only getting around 740k rn

[mortal gazelle]

yes there is

nukes interact weirdly with gt cables and provide power in chunks of power

so depending on the cable voltage/amperage you could have very strange results

[foggy zenith]

oh i see

ok yea that clears up, appreciate it

[maiden yarrow]

its specifically not able to divide amps of output

unless you give it an output that absorbs its entire output into one amp and then it will be lossless

for example if you output a 99% mox as ZPM, you will get the whole 108,000 eu/t. However, if you output it as IV, you get 8192 x 13 = 106496 eu/t.

[foggy zenith]

ohh

[errant cloud]

I though I could use 12-16x Aluminium cables initially until I noticed it was too much for them. In response I used I think 4x? EV Superconductors

[vivid junco]

im using 2 lines of 16x vibrant

for 4 nukes (2 per line)

[hearty crest]

Is there a document that tells the tick delay on all the project red/wireless elements

[vivid junco]

man...

switched to this and it worked for 4 days

and then randomly just gained heat

[stone sundial]

what coolant cell is better 360k NaK oder 360k He?

[maiden yarrow]

whatever is easier for you to make, functionally no difference.

[eternal bramble]

how? it's working perfect for me

[vivid junco]

i think maybe my buffer was too small

[eternal bramble]

how many reactors are you using?

I need to set this repeater to 16 ticks for it to work better in my case

you need to use transfer nodes, with at least 20 speed upgrades if you wanna use the 100% uptime

[vivid junco]

im not using 100% uptime

[vivid junco]

4 uranium

[eternal bramble]

add 50 ms to the timer

[vivid junco]

alr

[heady field]

bruh what the fuck is the deal w xp in the personal dim

[wide shore]

are you talking about how the levels disappear?

[heady field]

yeah

[wide shore]

yeah idk why it does that

at least they dont actually disappear for real lol

[heady field]

yeah but like

i had to move to the overworld bc the levels disappeared to do a soul binding thing

[wide shore]

if you gain any xp they come back

i usually just get a level from xp obelisk

[heady field]

wait i accidentally posted in the wrong chat, my bad

i was talking about xp bc i needed staballoy construct spawner for the vacnuke

[heady field]

is this circuit still good for normal uranium and mox vacnukes?

[vivid junco]

yes i use normal uranium with no issues

if you have a big enough buffer it works

i have a buffer of 20 coolant cells for 4 uranium nukes

would recommend

scales better than isoarcrees

[heady field]

you said you were gaining heat a few days ago, so i am concerned id have similar issues if i used uranium or straight up explosions if i used mox

[vivid junco]

the buffer was too small

i only had 10

raised the buffer, havent had issues

[heady field]

i see, thank you

[vivid junco]

ill ping you if i have more issues

[vivid junco]

bro i gained heat again wtf

[heady field]

uh oh

[wide shore]

[eternal bramble]

At this point try to use the Steve's factory set up

The problem is the reactor desync

[calm light]

If anyone stumbles upon this thread, I just want to mention that I've come up with an improved design inspired by this one. Less components, more compact, and arguably more intuitive. Full build guide is on the wiki. The AE2 method is documented there as well.

[hard prairie]

Hey, I hope someone here is still active. I want to upgrade from uranium rods to 99% MOX rods. My question is, how can I do it safely with having an existing setup? The setup that I used is something that is probably buried deep in this thread. But I'm also fine with building a whole new vac freezer setup

[calm light]

You mean just raising the core temp of the reactor? As long as you have a single fuel rod not adjacent to a coolant cell you can do so slowly but surely

Throw a lever on the reactor and watch it very closely

[hard prairie]

even to 99%?

[calm light]

Yeah, if you have a single fuel rod (as opposed to a quad) it'll increase less than 1% each second

[hard prairie]

I mean to me it is just a bit scary to do it but it has to be done

[hard prairie]

so I can do it with a uranium rod as well, it doesn't have to be MOX?

or even thorium?

[calm light]

Correct, the core temp is constant while the reactor is off. Safely make any changes after you raise the core temp with any type of fuel rod

[hard prairie]

One more question, do you happen to have any idea how much power does a 99% MOX reactor would output?

[calm light]

Values are on the wiki, over 100k eu/t

[errant cloud]

I'm looking at your redstone circuit. My concern here is that I don't see a measure for pausing the reactor during fuel rod switching compared to the other design shown in the original post. Am I missing something here in looking at the instructions or this is how it's built?

[errant cloud]

Let's see if I can add a remote comparator to the new redstone circuit design.

Place an item conduit set to ACTIVE WITH SIGNAL above the drawer and filter it to insert/extract the correct fuel rods. This conduit is only enabled while the reactor is running.

Oh, there already was a measure in place for fuel swapping. Nvm, to be tested in a creative world to understand how it works.

But this is leaving me with another question. How does the fuel rod conduit receive a redstone signal here?

[calm light]

Good question. I realized that fuel rod swaps are perfectly safe to do while the reactor is running. The conduit connected to the drawer is enabled by the "Controller" receiver. The redstone signal is carried through the chamber that it's pointing at. In the end it reduces the redstone necessary and deconflicts with coolant cell swaps, very nifty.

[static gale]

I built a VACNUKE and I'm using uranium, but the 180k coolant are reaching 25% heat not in 55 seconds as expected, but in about 30 to 33 seconds. Is something wrong, or did they change it in an update?

[errant cloud]

180k coolant? What coolant cells are you using? the 55s timer reflects on 360k He coolant

[willow pawn]

yea you are using the wrong coolant cells.

[errant cloud]

Not that you'll need to set different times depending on the coolant cells

For example you can have the timer be longer when you have 540k SP coolant cells in IV.

[static gale]

My issue is fixed, thanks everyone.

[errant cloud]

Different topic but I want to know how did you determine that 65s is the ideal timer setting for 360k He Coolant. I'm thinking that I can get away with a longer run time with 540k Sp Coolant but I'm not confident with doing so.
