I was finally able to build a fusion reactor on my SMP server. Even using AE to craft all the parts, it still took a long time to fab all of the parts.

I wanted to set it up to be self sustaining, and created a setup based off of some others that I've seen. I used eight Industrial Electorlizers fed by four Aqueous Accumulators, 14 Industrial Centerfuges making Deuterium out of the Hydrogen cells, three Industrial Centerfuges making Tritium cells with the Deuterium, and a Centerfuge Extractor to empty the helium and compressed air cells. This is all connected and 'automated' using a fairly simple AE network consisting of a controller, chest and an import and export bus for each machine.

This setup works fairly well and is reasonably balanced. It's creating the deuterium and tritium cells a littel faster than the reactor is using them, but in more or less equal quantities. My concern is that given enough time, it could possibly become un-balanced and run out of one of the resources.

So I set out to redesign the setup. In my SP world, I set up a reactor (haven't fired it up yet though) and set to creating something different.

I set the reactor up with a Liquid Transposer on top and one on bottom, with the transposers being fed empty cells via ME export busses, and an import bus on the reactor to grab the empty and helium cells. The transposers are being fed by iron tanks (I set up four 2,000,000 unit tanks, one each for Hydrogen, deuterium, tritum & Helium). I have a Liquid transposer on top of each tank being fed their respective cells via AE export busses, and I have a setup of Industrial Centerfuges similar to that in my SMP world. They, however, are being fed by Liquid Transposers.

This is where I'm not sure of the best approach. Right now, the transposers are emptying into relays, which are sending the cells into redpower tubes that are connected to the machines. Each of the three rows of machines has its own transposer and relay. The problem is, when the ceterfuges fill up, the cells start queuing up in relay, up to nine stacks of them. That is not ALL bad, but it seems a little goofy.

Is there a better way to manage the output from the transposers without an 'Inventory in the middle"? Ideally, I'd like a way to have it so that if all the machines are full and the transposer is full, it stops. Then one one or centerfuges empty, cells are sent on to the machines needing them and the transposer can then fill back up and wait again.

I would like to be able to produce both deuterium and tritium faster than the reactor uses is, store it in the tanks, and when the tanks are full, everything can back up and halt until a tank needs more, send the needed cell along and refill.

The other part I was having trouble with is the helium cells. I would like them to empty into a tank, but then when (and only when) the tank fills up, send the cells to an extractor to be emptied so as not to store any helium cells. I only want empty cells stored in the ME chest.

Does anyone have any thoughts?

why use liquid transposers when you can pump liquid deuterium and tritium directly into the material injectors? you could use liquid tesseracts to make it less cluttered around the reactor.

if you look at processing times for each recipe, you need 144 centrifuges and 32 electrolyzers (with about 6 aqueous accumulators) for the production line. less so, if you overclock your machines....but your machines will be powered by the reactor, so upgrading the system is academical. if you require more details in terms of numbers, let me know.

What do you mean 'material injectors'? Edit: Never mind - I'm on ultimate 1.0.1, so I have GT 2.81a and as a result, do not have the newer Fusion reactor setup or components.

Where do you get those numbers from? Using GT Industrial Centrifuges, it takes 150 seconds to get a Tritium cell from four deuterium and the same to get a deuterium from four hydrogen cells. 15* Centrifuges making deuterium and 3 making tritium makes for just a little more deuterium than is needed by the three centrifuges making tritium. This will produce 4 tritium and 14 deuterium every 150 seconds; the reactor uses one of each every 51 seconds, so every 153 seconds, the reactor has used three of each while the machines have produced 4 tritium and 15 deuterium. The net result has been my deuterium and tritium 'stockpile' has slowly increased over the last few days.

* = (My count was off by one - I have 15 centrifuges making deuterium)

i'm guessing by your question about material injectors, that you are still on Ultimate 1.0.1?

Is it confirmed that you can pump it in?

Since I'm on Ultimate 1.0.1, I can't confirm, but what would be the point of them if you can't?


Ok...in future, you should specify what version you're on....the new reactor set-up is drastically different to say the least....and my numbers were relevant to the new set-up.

Anyway, iirc, in my old set-up: 6 electrolysers to produce Hydrogen cells. 20 centrifuges to produce Deuterium cells....for every 5 cells, 4 are sent to another 4 centrifuges to be processed into tritium. This set-up was self-sustaining...whether you use cells directly sent into the reactor, or whether you empty the cells into tanks first....it's self-sustaining.

If you're getting a surplus with your current set-up, you should be fine.

Edit: with regards the helium cells. if you have no plans for them, forget the tank, if you do, then use a quantum tank instead and you'll never have to work about running out of room for the liquid helium.

Ok... I redesigned my reactor setup. Granted, it's the old version and will get more insane when updated.......

I set up three tanks: one for Helium, one for Deuterium and one for Tritium.

I set up 16 Industrial Electrolyzers making Hydrogen cells. I also set up a ME Level Emitter and a dark cable so that if I have 384 Hydrogen cells in the ME chest, the ME network will stop pulling from the Electrolyzers. They will continue to produce until full.

I have 40 Industrial Centrifuges making Deuterium. The Deuterium cells go to the Centrifuges that make tritium and the tank as needed. I have a dark cable and level emitter set to stop pulling from those centrifuges when I have 384 Deuterium in the ME Chest. Same as the Electorolyzers, they will continue to produce until full.

I then have eight centrifuges making tritium. the tritium goes to the tank, and when I have 128 Tritium in the chest, the AE network will stop pulling from them.

I then have two centrifuge extractors for Helium and compressed air. The compressed air one reclaims the compressed air cans immediately. I have a dark cable and level emitter set to turn the cable on if I have five helium cells in the chest. This means that the tank is full and the cells are starting to overflow into the chest.

It's taken a little watching to make sure I don't run out of empty cells, but once I hit the point where it CAN'T run out of empty cells, it should, in theory, be able to run forever (Until I update and have to redesign the thing). The nice thing about this setup is aside from adding machines to keep up with the demand, it's ready to feed the new style reactor without cells.

Semi-related.... What's the trick to getting all of the power from the reactor? According to the Wiki, the reactor is supposed to make like 32K EU/t in 2048EU packets. I have two HV transformers on the reactor taking two feeds off each, and when I hooked my Mass Fabricator up to it, it was only pulling like 3600EU/t. When I hiiked my 12 UHSP's up to it, it pulled about 6000EU/t. Am I missing something?

Yess, you should use 2 supercondensators, to convert the packets down, and then build 32hv transformers i believe.

Something still doesn't seem right... I re-engineered my setup again as XFXXFX suggested, with Super Condensators on the fusion reactor, superconducting wire to 32 HV transformers and it seems to peak at 8192 per Supercondensator. Is this the cap or should I have it set up differently?

Edit: Never mind, figured it out... you need four supercondensators patched through to the 32 HV transformsers to get all 32K EU/t.
