    That's pretty sweet. The row of 4 chamber reactors will look awesome too.


    The reports on gregtech changes are pretty awful :/


    Check what pure plutonium and pure thorium reactors put out?


    The uranium cost is interesting, btu there are going to be far far cheaper ways to cool it.

    Running costs are pretty reasonabe even with NRs as long as you have a big enough setup actually. 8 quads overcomes the energy (via UUM vanilla, or lava centrifuging with quad plutonium cells gregtech) needed to make quads nicely. Coal dust might get problematic eventually though.

    Lava won't be worth the tin.


    Assuming NaK cells and a plutonium efficiency 6 design, you need 251.4 cells per plutonium quad cell each cycle, that comes to 2,262.6 tin, or 18,100.8 buckets of lava, enough to make 543 million EU. You get 96 million EU in return.


    Might work better with vanilla IC2 and a fabber, iirc, its 3 UUM of 5 tin ore, assuming you use TE to triple instead of double the tin ore output thats 33,333.2 EU per tin. You need four tin per coolant so that comes to... 10,726 tin or 357.5 million EU for a reactor that outputs 192 million EU.


    Yeah, not viable.

    The question is, is the lava worth the reactor? I did the math for some of the higher copper cost reactors and it isn't always so (it takes 80 million EU worth of lava to run the 4 reflector 1 quad reactor through a single cycle, which gets 24 million EU).

    The question is really why bother building this. Yes it produces over 1500 re-enriched in a 50,000 second cycle, but unless you plan to build 25 or 30 reactors you don't need that kind of speed, even a more moderate single cell breeder design is probably too fast. Far better to adjust the design for low cost, rather than high output.

    Should work well as long as the microcycle time is long enough to let the cart take its time making a circuit. I guess the thing could be made to run faster than it does for me though? I didn't mess with acceleration beyond what I needed to get the cart to the next loader/unloader


    You'll probably still want something else for extracting the hot cells (and I am for removing fuel anyway, don't want to lose time waiting for the cart to pull out the depleted/reenriched cell, but removal is easy), it'll be good for moving the cold cells from cooling tower to regulator (or whatever you use instead of a regulator). *not* good for HVC reactors, too slow. i would also conbine it with a run only when full redstone signal if you don't have one already , just in case the cart is a little slower to deliver than expected.

    So I did some math on copper efficiency and gregtech lava centrifuging. Assuming you're using TE to manufacture lava for sustainability, and efficient electric engines (2.5 EU/MJ) to power the crucible, the effective output of a reactor should be reduced by .2525 for each copper in a thorium cell, .63125/copper in plutonium, and 1.2625 EUt per copper in a uranium cell. Higher consumptions may be necessary for non iridium reflectors (the tin output of the centrifuge will be evenly matched, coal is a problem).


    Some results: the quad cell+4 reflector setup takes 212.1 EU/t to sustain, more than it produces.


    The normally highest overall efficiency reactor takes 121.2 EU/t to sustain. Its gregtech overall efficiency is 2.02. So worse than 0 running cost setups.


    The highest copper consumption hybrid (the 420) takes 7.575 EU/t to sustain, giving it a 1.8% automation loss. The thorium neutral takes 6.3125, for a 1.7% loss. Even when thorium life is halved the stuff should still be viable in multicell form.


    Nether lava centrifuging should work out much better, though its not really possible to 100% automate that. There's also a question of lava efficiency, IE, is that lava worth more in a thermal generator. The 4 reflector setup would consume 2,688 buckets of lava every 10,000 seconds, equivalent to 80 million EU. That same reactor will produce just 28 million EU in the same period.


    As for a hybrid, the thorium neutral reactor will produce 367 million EU, compared to just 3 million EU worth of lava.


    Also: Peppe, I need to thank you yet again, the railcraft based reactor refueling system is incredible for multiple reactors, I've got it maintaining 5 reactors in creative right now. As best I can tell the system should be trivially expandable to any number of reactors.

    The reports I've been hearing are 2-3 days per pump. Also, you ahve to put down a gigantic chunkloader, there's not much of a worse way to use server resources. Though, quantum tank could fix that if the output is high enough.
