[Official] New Reactors design thread.

  • Uranium to plutonium that's used for MOX is breeding, at least as much as near-depleted uranium cells being reused was, and under the old definition deuterium into tritium is breeding too (although that's fusion not fission, and isn't used by anything yet).

    145 Mods isn't too many. 9 types of copper and 8 types of tin aren't too many. 3 types of coffee though?

    I know that you believe that you understood what you think I said, but I am not sure you realise that what you read was not what I meant.

    I see this too much.

  • What you tell herr Chocohead: Breeding is wasting uranium to get a product out of it to make a different type of Uranium.

    Thats not the case. Create a new term for that because breeding is already used for a different one..

  • Breeding is simply turning fertile isotopes into fissile ones; it's not wasting uranium at all, because the isotope that you start with couldn't be used in a reactor anyway. And what you end up with (or start with for that matter) doesn't have to be uranium either, breeding uranium 238 (which is what you do in IC2) actually makes plutonium 239 in real nuclear reactors, hence MOX exists. The term doesn't need changing, redefining or replacing because it still holds true for the process that happens.

  • Could we possibly move just the reactor designs that still have working links to a new, locked thread that is only updated with newer designs that are improvements on previous designs? I really do not understand the mechanics of the reactors very well and I'm just looking for a design that will let me make a decent amount of hot coolant from my pressure vessel reactor. I am trying to get lots of EU/t to run a huge number of mass fabricators, recyclers, etc. and am finding that there are not very many working links to reactor designs. Most links are from 2012/2013 and are dead links because the original hosting services haven't retained the images.

    Going forward, hosting on Imgur seems to last indefinitely and it would be nice to post screen captures of reactor designs there.

  • Aroma, my mind is BLOWN my man.

    Thank you for this.

    Do you by any chance know if there's a section somewhere where the subject of Pressure Vessel reactors is discussed? I'm trying to go that route instead of straight EU production because it's at least in theory more efficient.

  • It's been a while since I last dug out the reactor planner. I was looking to find the highest efficiency possible (for fluid reactors) that is easy to automate, and I found this:

    EU/Tick: 260

    Efficiency: 4.33

    HU/s: 1199.99

    Efficiency: 11.67

    Overall Efficiency: ???

    Cost: 372 Copper, 64 Gold, 460 Iron, 10 Redstone, 30 Rubber, 125 Tin, 12 Uranium Fuel

    Running Costs: 9 Iron Plates, 6 Copper Plates

    Reactor Code: 03030C0D11090C0000030C0D0C0D0C0D0C000C0D0C0D0C0D0C09000D0C0D0C0D0C0D1100110D0C0D0C0D0C0000090C0D1109110D0C00

    I think it's one of the cheapest full size reactors I have come across, and provides a high efficiency (and so works well in a fluid reactor). I think the best automatable uranium -> HU conversion is using reflectors, but I think that this is likely a close second. In a non-Fluid setup, it can even be pushed into a five chamber design (as shown above), should you ever need to save on resources, or fit a reactor into a 3x3x2 space.


    In the quest for the "best" Fluid Reactor, I started exploring Reflector-based designs, and dug up a few older ones (with a few tweaks to make them cheaper), including this:

    EU/Tick: 260

    Efficiency: 4.33

    HU/s: 1343.86

    Efficiency: 21

    Overall Efficiency: ???

    Cost: 512 Coal, 728 Copper, 92 Gold, 4 Iridium Reinforced Plate, 485 Iron, 14 Redstone, 42 Rubber, 646 Tin, 8 Uranium Fuel

    Running Costs: 6 Iron Plates, 4Copper Plates

    Reactor Code: 2303230C09110D0C0903230C0D0C0D0C0D11230C0D0C0D0C0D0C0D0C0D0C0D0C0D0C0D0C0D0C0D0C0D0C0D0C0D110D140D140D110D11

    With ~1,350 HU/s, it appears to be near the peak of HU/s, and also simultaneously requires somewhere around the least fuel input, despite outputting the most power. I understand that makes it a slow MOX Breeder, but does anybody have a superior design for a liquid cooled reactor?

  • Nuclear jetpack reactor

    EU/tick 200
    Efficiency 3.00


    Don't know about running costs as I have no idea how to calcualte it or what t is :D

  • I'm not sure why the planner lists HU/s since the number it shows is HU/t. If you build any of the fluid reactor designs in-game you will notice that the reported heat is 20x the simulated heat (it's showing HU/s in-game and HU/t in the simulation).

    Here are the best reactors I've come up with:

    You can squeeze a little bit more efficiency using Iridium Reflectors, but those are hilariously expensive compared to the increase in efficiency.

    EDIT: Upon closer inspection, Korlus' fluid reactor design (minus the reflectors) is slightly cheaper than the 12 Uranium Rod design I initially listed. Cheapened it further for the lower heat demand and updated the spoiler block.

  • Hello, I wish to put here one of my designs with ask about stability of that - as far reactor planner only showed - when simple cycle is setted up, that few components has orange and yellow bars upon it; and as Im standing just before running one, nothing bad seems to happen - all exhangers seems to keep around stable meta numbers. It uses four quad thorium cells surrounded by iridium reflectors. All builded in MC 1.7.10 with GT 5.9.31 and IC2Ex 2.2.826

    It gives around 900Hu/s; only steering for that is for now temperature switch from Nuclear Control 2, switching off reactor at 6k *C. After all, it will be still usable with Uranium, MOX and Naquadah, or shall I check someting different for those materials?
