I know nothing about nuclear reactors, I just copied someone's design for my reactor. Anyway, I was wondering if there were any good nuclear reactor designs that didn't require quad or double uranium cells, (they require tons of copper) but still produce a lot of EU. Help would be appreciated, thanks.

On the industrialcraft forums there's a bunch of good reactor designs (hell there's even a thread dedicated to them). You should look there. A word of advice though: the extra copper needed is negligible compared to the extra energy you'll get from using dual and quad cells.

This is probably the best single cell based system 100 EU/t 3+ efficiency:

Note that it has to be built in this exact orientation due to the way heat is processed by the reactor. Don't try cells on top.

Reactor is from this thread:
http://forum.industrial-craft.net/i...81&s=b0c16186ddb67a628e0dacd8ab44101bbb7dd88c


You will also want to use a breeder reactor to get urnaium cells instead of making them directly out of the ingot -- you can get 1 uranium cell from an ingot or 8 near-depleted cells from an ingot.

Add coal dust to the near depleted cells and they become isotope cells that you can recharge in a reactor. Depending on the heat of the reactor the isotopes slowly charge up to become a re-enriched cell (at 0 heat it takes a full uranium cycle to charge). Add coal dust again and you have a full uranium cell.

My starter breeder is usually this design, which can recharge 7-8 times in the life of the one uranium cell:

centrifuge 2 uranium cells into a thorium cell, then put that in your breeder above instead if you run gregtech.

For a start non-copper eating reactor, the one linked by peppe is great - I use it too.

Personally I use a slightly different breeder that only has 1 stack of heat cells. It stays at full temperature even when the reactor is turned off so I don't understand why people use 2 stacks

Can you post the single cell design? To hold the heat when off the cells have to touch enough parts to counter the reactor venting which is usaully 60 in a single cell + 4 isotope design.

I use multiple heat cells for the early breeder otherwise the temp is lost when off. I evolve the design above into this later:
http://www.talonfiremage.pwp.blueyo...ugprk4m9ktbcsgsh687fteav754p1xwkhrbqlbyomzfck
So the split stack isn't wasted -- eventually you will need/want 64 heat cells anyway.

from

http://forum.industrial-craft.net/index.php?page=Thread&threadID=7681 OP's first breeder (credit to stretchydeath of IC2 forums on design)

I'm not sure where this idea of the heat dropping is from. I used this design on my 1.4.2 server and it did not drop heat while off. I could come back the next day and the reactor would be just as hot according to a thermometer (and visually). From what I can tell as soon as you have heated it up it will stay heated until you break it or remove the cells. I know you will want 64 cells for an efficient breeder later on but that is a lot of material (which isn't displayed on the planner) to dump into extra cells early-mid game.

As someone that's not dabbled with nuclear stuff before in FTB I find this to be an interesting thread. The link from Peppe in post #4 is what I want to build but how do you actually put it all together? The FTB wiki details are non-existent and the IC2 wiki page does go into great detail but no illustrations of layouts. In Tekkit (prior to the changes) there were HV transformers and 4x ins HV cables involved from what I vaguely remember. Is this still the case or can you just hook up a fibreglass wire from the reactor straight into your MFSUs now?

You can size the wire to the reactor's output.

I've used tin wire off my breeder reactor before (5 EU/t), so it was safe... though it electrocuted in what seemed like a 2 block radius. Ran it into a bat box for some machines to use.

For the 6 single cells together the output is only 100 EU/t, so you can use gold cable off it. Probably input to an MFE, but really size it to whatever you like.

Diamond cable is easiest to use without introducing loss to your system, but all the cables have a role if you know how to use them.

Most of these reactors are the safest type, so its not even going to build up heat or risk a meltdown. I run the reactors above in my base next to other machines. Unless it is a breeder running in the damaging range, then I'll tuck it back a little, but for the most part if the sim says 'full cycle' the reactor is safe to run 24/7.

If your reactor outputs less than 512 EU/t, you can just do that. If it's more than that, the current would fry your cable and/or blow up your MFSU. In that case you need to attach an HV transformer with its three-dotted side directly adjacent to the reactor, and run the fiber cables from the transformer to an MFSU. (You can use HV cables, but I don't see why you would want to, as they lose power even over one block of wire.)

Thanks. I don't know how I overlooked that. Of course fibreglass cable will be fine for 100 EU/t. So I got the reactor #3 up and running from the link and worked fine without any babysitting, but not keen on having to manually replace the cells every 2:46 when they run out. Is there a way to automate the removal of the near-depleted cells and put in new ones? (I don't have RP2 btw). Also I've noticed that I only seem to get either 1 or 2 near-depleted cells back, the others vanish. Is that a bug or normal? Shouldn't I get all 6 back?

Can you explain breeders to me? Are these just reactors that "recharge" depleted cells? I was looking at both the breeder #1 and breeder #2 in the link above but don't see the difference between them apart from one uses nearly 3x as many resources as the other. From what I can see, both only recharge 4 cells so you'd just stick with the lesser resource version? Are breeders just like a recharger for your empty cells or do they output power too? What happens when the cells have fully recharged? Do you have to remove them and put some more empty ones in or ?

What I need is a LOT of power to run my matter fabricator and my geothermal gennies, adv solars and reactor #3 just aren't cutting it. I am thinking of building 3 reactor #10s at 360 EU/t each and the breeder #1 to recharge the depleted cells, and then hooking up the reactor #3 I already have, the geothermals and adv solars into an MFSU on the 4th side of matter fab. How does that sound?

Are there any good tutorials on how to automate the replacement of the depleted uranium cells so you don't have to do it yourself? There's a few on YT but they are using the old style version with ice so no good.

Thanks! :D

Assuming you have the Beta modpack, try either GregTech Translocators or Factorization Routers.

Working as intended. Every uranium cell has a 25% chance to become a depleted cell. Otherwise it disappears.

Can you explain breeders to me? Are these just reactors that "recharge" depleted cells?
Breeders can turn depleted cells back into usable uranium cells. You can use them to recycle your main reactor's output, but you can also craft 8 depleted cells out of one uranium ingot. If you recharge them in a breeder, you increase the energy you gain from uranium many times. Link: Breeder on IC2 wiki.

I was looking at both the breeder #1 and breeder #2 in the link above but don't see the difference between them apart from one uses nearly 3x as many resources as the other. From what I can see, both only recharge 4 cells so you'd just stick with the lesser resource version?
If you look at Core Heat in the top right, the second reactor runs at much higher temperature. This means it will recharge the cells faster. In other words, using one fuel cell, it will recharge more depleted cells than the first one. (30 depleted per fuel cell for the first, 88 for the second.)

Are breeders just like a recharger for your empty cells or do they output power too?
You can make a so-called hybrid breeder, which breeds and produces EU. However these tend to be not very efficient at either. Generally it's better to have one reactor for each purpose.

What happens when the cells have fully recharged? Do you have to remove them and put some more empty ones in or ?
They turn into re-enriched cells, which are inactive in the reactor. You can turn these into regular uranium cells by adding some Coal Dust. Ideally you'd want some automation to pull them out and put in new depleted cells.

What I need is a LOT of power to run my matter fabricator and my geothermal gennies, adv solars and reactor #3 just aren't cutting it. I am thinking of building 3 reactor #10s at 360 EU/t each and the breeder #1 to recharge the depleted cells, and then hooking up the reactor #3 I already have, the geothermals and adv solars into an MFSU on the 4th side of matter fab. How does that sound?
One thing you should be aware of is your EU throughput. No matter how much energy you pump into an MFSU, it will only ever output 512 EU/t. Therefore if you are producing more EU than that, it will become a bottleneck in the system. You will need either a direct wire from your reactors to the massfab (a wire has no EU/t limit), a better storage unit (one of the GregTech ones), or several MFSUs connected in parallel.

Are there any good tutorials on how to automate the replacement of the depleted uranium cells so you don't have to do it yourself? There's a few on YT but they are using the old style version with ice so no good.
Translocator from your main reactor to a chest, BC Autocrafting Table adjacent to it making Isotope Cells and sending them to another chest, another Translocator taking them from there to the breeder. Second line has a Translocator going from the breeder to a chest, an autocrafting table again making uranium cells into a fourth chest, and a translocator sending them back to the main reactor. Translocators are intelligent enough to stall when there is no space for their items, so you won't end up with stuff lying on the ground. Just make sure that the only empty spaces in your reactors are where the cells go, or the translocators will put them in the wrong place. (Fill other empty spaces with platings, if you have some.)

Keep in mind that breeding is not 100% effective, as you lose some cells in your main reactor no matter what. Therefore you will still need to add more uranium over time. (As I said previously, it is more efficient to add it in the form of depleted cells.)

Abdiel, that is a really useful post, thanks a lot! I was not even aware of the translocators and strangely for gregtech they have a reasonably cheap recipe to make them too. I will definitely be experimenting with them!

For some reason I thought that the matter fab only accepted a max of 512 EU/t from each side but must have got confused with something else as I see they accept 8192 EU/t per side according to the wiki.

Which reactor and breeder would you go with to power the matter fabricator in my situation? I'm pretty flush with ores for all their internal stuff, and I can probably stretch to a total of 9 MFSUs before being out of diamond again.

GregTech automation machines are really neat, and they can manage some things neither BC pipes nor RP tubes can. I recommend you play around with them for a while.

I've never used reactors a lot, and I've never used a massfab ever, but I would suggest focusing on energy efficiency per piece of uranium. You don't need a huge EU/t output, but you will be constantly running out of fuel. Therefore you want to get as much power as you can from the uranium you have. If you automate breeding or at least inserting new cells, you can just let the reactor run overnight to process all the uranium.

Hi Abdiel, just playing in SSP trying to get the new re-enriched cells out of the breeder but having some problems.

http://imgur.com/JgiBj

The first translocator is pulling the re-enriched uranium cells out of the breeder just fine with one placed inside. In the ACT I have 1 re-enriched uranium cell and a coal dust next to it. I've put some stock of each in the chest next to it. In the 2nd translocator I have a new uranium cell, but it's not pulling them from the ACT. If I remove the uranium cell from it, it happily pulls the coal dust and re-enriched cell from the ACT and puts them in the chest. What am I doing wrong? I've tried putting the translocator on the top of the ACT to pull them out but that doesn't work either. How do I get the 2nd translocator to pull the new uranium cells out of the ACT?

I tried it like this as well

http://imgur.com/SdPRp

But the 2nd translocator transfers EVERYTHING (including its filtered inventory) into the 7 empty spaces on the ACT next to it, which then messes up the uranium cell recipe in the ACT. Also the output pipe of course pumps continuously and as uranium cells don't stack that causes problems when the chest gets full.

I can get it to work with the GT electric crafting table in between the 2 translocators, but I read that it consumes a whopping 5000 EU for each operation. :(

final chest <- relay <- wooden pipe with redstone engine or aut. gate <- ACT
final chest has a cobblestone pipe with a gate: if chest has space, emit redstone signal. Connect that signal to your engine or gate to start pumping. The relay is a small buffer, auto outputting if space available, thus the two or so cells that get produced each time until the engine gets shut down again won't spill.
