Note: the energy and fluid spreading between e-magnets and active coolers is disabled by default in the configs - if it does not work for you and you'd like it to, check that this is enabled first! For those who want some more equations: Power[RF/t] = Toroid Size × Efficiency[%] × Combo Base Power Heating Rate [kK/t] = {100 - (0.9 × Efficiency[%])}/2 - Active Cooling Rate

[@Mr101600]

After spending 12 hours straight on building my first reactor setup, I was finally ready to build a fusion reactor, or at least start looking into it. So naturally the first thing I do is come to this video to do so right? Well, within less than 1 minute of being afk on my server one of my friends messed with my reactor and it had a meltdown. So now Here I sit, reactor-less and sad.

This mod is awesome and has a lot of potential. I appreciate you making it more visually understanding with showing which blocks are energized and adding support for computercraft. My biggest critique is adding more in-game guidance. For example, a building guide with phantom/ghost blocks to show a player what's needed for a fusion reactor, at least the toroid. I would actually turn the fusion core into a multi-block structure that allows the player to designate the power output and fluid input/output. Next, I believe adding a book to explain your mod would helpful as well (if there isn't already). This would most definitely help with setup and use of your mod. Lastly, I personally think the variety of fuels is cool but it's overwhelming to someone who doesn't fully understand nuclear physics. I could see you removing some fuels and/or adding in the details of the fuels their atomic information like protons and neutrons. Adding the atomic info will teach/help anyone with figuring out the underlying physics. Sorry for the essay, but I hope you find this useful and I look forward to more updates in the future!

[@NuclearCraftMod]

First off, thanks very much, and your welcome :) I've thought a lot about stuff like in-game guides, ghost blocks and such. The former is something that I've always wanted to do, but I have very little time to get done. A couple of people have expressed wanting to help with that, although not much has cropped up so far. I write a lot of info on the tool-tips of blocks and items, but from watching players on YT and Twitch this somehow almost always goes unnoticed :P Still, it's important and if the to-do list thins out a bit, I will work on it. In there I could also have info detailing some of the details of the physics involved, as you recommend :) The latter is something I'm sitting on the fence for - although it would be useful, I'm not sure that, given the amount on the to-do list currently, implementing ghost blocks would be a good use of my somewhat limited time. After all, the fission reactors can be any size, so the only place they would see any use is, as you say, the fusion toroid. The thing is that they will change entirely in 1.13 and will allow for a variable minor radius, so then I would even be sure how useful they would be in that case. And yes, a multi-block fusion core is a really nice idea... and is exactly what will be added in 1.13 :)

That said, in the past few days I've been looking for a fuel usage formula, that can tell me from the base consumption and other variables, how much a n-sized fusion reactor would need. Other than that, I think that the FTB wiki could bring some of this specific data. Of course, only if this is in you domain of work.

Just set up a toroid 3 reactor and I've done some active cooling with it. However, I'm at 101% Active Cooling Rate using just water. Removing a set of coolers decreases the rate to 96%. I realize I can use a combination of fluids to achieve a flat 100%, but will the 1% make much of a difference? Am I fine to leave it there?

So I'm unsure if I'm understanding this right or not, if you have the active cooling at 100% (or higher), will it not ever reach meltdown, or is that still going to happen unless every so often it is shut down briefly to cool down some? I'm not a big fan of running the redstone with a comparator to have it maintain itself, so want to make sure if it's really necessary or not first.

[@NuclearCraftMod]

If you have 100% cooling or more, yes, it will run forever as long as the core has fuel and the e-magnets have power. No comparator required!

[@speedstyle.]

_the other liquid coolants are much more powerful, and you do I think need them for large enough reactors - I don't think a size 4 is a good example ... but if you have like a size 24 I think it's possible you may need to use something better than just water, because eventually you'll just run out of space_ If coolant power is divided by (linear) size, surely you always have enough space for water cooling? For size 𝑛, you have 2𝑛+2 spaces per inside row and 2𝑛+4 per outside. 4× for the sides of the square, 2× for top and bottom, and 4× for mirror efficiency, gives 128_n_+192 blocks worth of cooling. For water at 200K/t/𝑛, you only need 25𝑛 to reach 5000K/t, which takes less than one-third the space. You can even just expand the pattern you made in this video (using the same proportion of each quadrant). Is the coolant division done differently than I understood?

[@NuclearCraftMod]

You are right, yes. When I recorded this, I hadn't actually realised that was the case :P

[@Spatabaz]

Hey, i have a question. Every time I try to shutdown the reactor using a lever, the magnet ring keep exploding, why ? Edit : I have my respnse thank you, the reason why it has exploded was because the magnet lost power and the plasma escaped.

[@thenax7998]

Trying to make a Toroid 2 fusion reactor in Enigmatica 2 expert. Having 2 active water coolers gives 400k cooling, which fits with the video. Adding more coolers, even mirrored, either does nothing and sometimes even reduces the amount of active cooling. What's going on, or what am I doing wrong?

[@itDingle]

For sake of not wasting all my materials and possibly melting them all, I usually test reactors in creative before trying to use them in my actual game. I'm trying to replicate the exact reactor in the video here, and for some reason the power im supplying to the electromagnets isn't spreading between each other, I would have to manually connect each and every cell to a power source to power them all, and with the need of coolers, that obviously can't happen. I'm using enigmatica 2 (standard) version 1.53 . Does the fact that I'm in creative cause problems, or what's the issue?

[@NuclearCraftMod]

Hey there - in order to get the energy to spread between the e-magnets, and various other effects like active coolers spreading coolant between each other, you need to head into the NC processor configs and enable 'passive permeation' ;)

@@LetsPlaywithDDae Unfortunately there's not much I can do about the illuminators. For some reason they have their material type set to rock, so they're unwieldy to check for.

[@LetsPlaywithDDae]

NuclearCraft I had two liquid helium active coolers hooked up before I heated it up. It heated up to 8k and then bricked and got stuck flickering between -500 and 1k.

at max size you should be able to do it with only water i think ....

Yep, pretty sure you can. Each cooler should be operating at 1/6 efficiency (4/24), so each is producing 33.3K cooling so you only need ~150 to get 5000K (or ~75 pairs). There are as many diagonals as electromagnets, so you shouldn't even need to make a half ring on either side.

If the temperature decreased, it means the reactor wasn't running. If the e-magnets exploded, that means they lost power and the plasma escaped.

[@stragulus]

How do you hook up a comparator for the smallest size reactor? There is not enough space at the bottom then.

[@NuclearCraftMod]

A redstone signal can travel into an e-magnet block, so with a couple redstone torches you should be able to loop the signal through the bottom of the ring and back.

[@stragulus]

@@NuclearCraftMod Thanks!

[@NuclearCraftMod]

@@stragulus No prob :)

[@ToqTheWise]

For some reason I can't get power to spread to the other electromagnets. I'm only using Immersive Engineering.

There is a config in the 'processors' section called 'passive permeation' that must be enabled for energy and fluid to spread ;)

Once my reactor starts while running on hydrogen it runs through the stored hydrogen in a few seconds then shuts down. Any suggestions? Having a great time with this mod!

If it’s running through fuel very fast, it could just be that you’re not producing and inputting it quick enough?

I'm playing Sky Factory 4, and thanks to this modpack we can generate everything out of thin air :D Is there a difference in energy output from different fuel? Or just the optimum temperature is changing? I've heard (and know from other mod) that the reactor explode when it's overheating, but in your video you said it just become lava? What's the real risk of overheat? Also great mod, and great video. I've search it because there isnt ghost block like other suggested but this tutorial is enough to understand everything about fusion reactor. Good job :)

[@NuclearCraftMod]

Yep, different fuel combos will have different power production rates, fuel use rates and optimum temperatures - all of that info should be in JEI ;) Electromagnets will explode if they run out of power, but if the core overheats, it'll melt to lava. And thanks! I try to put a decent amount of detail into the tooltips of the items/blocks in the mod, but make the videos as well for those who find that sort of thing helpful :)

This thing still eventually explodes with 100% cooling, also no mod can manage the comperator signal from the core, it only updates once for anything except vanilla comperator and redstone trail

I'm guessing this is after running the reactor for a rather long time? As for the comparator, yes, that is a limitation - I'll find a solution for the overhaul, although the fusion reactor in this form won't exist any more ;)

Is it just me, or is this video very shaky? About 3:17 is one of them, and it happens quite often. Very annoying.

[@elliejohnson2786]

How does it actually produce power? It's unclear on both the wiki and this video. How do you extract it? From the base, or any side? Can it power its own magnets after it reaches a certain temperature? Literally the only thing this is useful for at the moment is making glowstone in Compact Claustrophobia. I can't extract power from it and it seems like a power-drain otherwise.

[@NuclearCraftMod]

Power is extracted from the core. Exactly how much it produces depends on the toroid size and the configs.

Im cooling my reactor at 252% is that bad or just over kill?

[@NuclearCraftMod]

A little overkill - you want to be at least 100%, but the closer to 100%, the better.

[@shade5350]

I cooled my reactor to 100% but it's not stable; it's going past 5000k .. Is there something else I'm doing wrong? EDIT: Found the problem. You have to build the cooling before it gets past 100% efficiency.

[@NuclearCraftMod]

Yes, there is always the possibility that you pass the optimal temperature, which can be a bit annoying to deal with and/or notice :P

[@athentdm5333]

Why can't I find the connector or conduit

[@emdash8944]

How do I disassemble the fusion reactor? Can't leave it idle since it will explode if the electromagnets lose power.

[@Byuel]

In real life reactors, there is no such thing as monitoring a reactor, flipping a switch to turn it off and go home and call it a day

[@emdash8944]

The fission reactors in this mod can in fact be flipped off with a switch so why should they make an exception to your argument? Realistically any type of reactor could be eventually halted and decommissioned.

[@NuclearCraftMod]

It's been quite a while since I last actually used the fusion reactors, but if the plasma doesn't disappear, you'll have to either keep the e-magnets powered while breaking them and placing blocks to remove the plasma, or wait for the temperature to fall below 8 MK.

Does anyone know a stable way to consistently power the electromagnetic blocks?

I would recommend not relying on the energy spreading for large reactors. Hooking each of the e-magnets up to a cable should help quite a bit... as long as the power supply is relatively stable :P

[@jadjnm7108]

Does this overheat and start melting like the fission reactor?

It'll only overheat if it hits the temperature limit, similar to the fission reactor. If the e-magnets run out of power, they will explode and the plasma will leak.
