My CASUC reactors

[Santi871]

Hello, for the past few weeks I've been designing and building CASUC reactors, both bucket and ice, and wanted to show them to you

I've been trying to make them as small as possible, and noticed that for 1000EU/t or less, water CASUCs are better, but for more than 1000EU/t they are beaten in size by ice CASUCs.

For the bucket CASUCs I made, the more the EU you want, the bigger the size. The best size/performance ratio I got was with the 1000EU/t reactor.

350EU/t water bucket CASUC:

Extremely small, low-technology, does not have overheating/meltdown prevention system. Also, the remote thermal monitor is fed by batteries which are stored in one of the chests due to the small size. Good reactor if you don't need a lot of power.

850EU/t water bucket CASUC:

Medium size, medium technology. Does have overheating prevention system, and the thermal monitor is fed by a solar panel (optionally, it can be fed by a batbox). Does not offer a reactor controller (overheating prevention system is simple).

Ignore the other stuff on the background

1000EU/t water bucket CASUC:

The same as the 850EU/t one, except it's a bit bigger and has a higher output.

2000EU/t water bucket CASUC:

Large size, hi-tech. Does have a simple overheating prevention system. This model is pretty much obsolete since it is very big compared to the 2070EU/t ice CASUC and has nothing better, but if you like high power water CASUCs then this is your choice...

2070EU/t ice CASUC:

Large size (although I find it small for the amount of energy it produces), hi-tech. The model on the pictures has a simple overheating prevention system, but optionally there is one with a complex reactor protection system with a better control panel and a reactor controller, but of course it will be bigger (pics of this soon). This is my favourite reactor.

The compressors have 15 overclocked upgrades each, a stack of storage upgrades (I needed to ensure they got as much EU storage as they could) and 3 transformer upgrades, since they are directly powered by the reactor's 2070EU/t when needed (when warmed, they don't really need much EU to work). This reactor is meant to be run non-stop, stopping for refueling should be done as fast as possible. However, if the reactor is off, there is a battery (MFSU) with 10 million EU available to have the compressors warmed up.

The only downside of this reactor is that for the first time start only, you need to feed it a few stacks of ice until it the compressors warm up for the first time and the reactor becomes self-sustainable. This will also happen if the MFSU becomes empty and the compressors completely cool down, but for that to happen the reactor must be off for a long time.

Everything this reactor needs is on the containment building (incluiding snow golems), nothing is underground, except the wires from the control panel to the reactor.

All of these reactors are Mark I.

Well, hope you got inspired and start making your own CASUC reactors, they are always fun to make cause everytime you build a new one you notice you can make it even smaller

PS: I posted this in the Tekkit section cause I use Tekkit both for SSP and SMP, these reactors were built in Tekkit not Technic. If you think this isn't the appropiate section and it should be posted under Technic SSP, move the thread (if you are an admin) or tell an admin to move it.

Is ice cooling not more efficient than bucket cooling? I know its harder to make ice but buckets don't seem to cut it just as well.

[warpspeed10]

Ice cooling uses EU for the compressors, whereas water buckets use none. If you want to squeeze every last bit of EU out of your uranium cells, go water.

[epicsquare]

The eu for your compressors you can provide with a few mv solar panels. Also water would need a filter pumping out empty water buckets and reusing them.

[warpspeed10]

a few mv solar panels

Heh, ya, just a few. No big deal.

[epicsquare]

if we're talking survival, i had 2 hv arrays prior to building the reactor. That should be more than sufficient to power an ice factory.

Using two hv solars to power your ice factory is really dumb, since you're giving up 1024 EU/t in order to gain 1000-2000 EU/tick... AND using up uranium at the same time. Basically throwing resources down the drain for no reason.

Any amount of power you use to power compressors must be directly subtracted from the nominal output of the reactor before you give it its label. So if it ouputs 1000 EU/t, and you use 100 EU/tick for the compressors, you have yourself a 900 EU/tick reactor. It makes absolutely no difference where the power comes from, solar or otherwise, because at the end of the day, the MFSU you are feeding doesn't care whether it is getting nuclear or solar power, etc, and they are entirely swappable in equations.

Opening post snip

I can make a 2000 or so EU/t reactor ice cooled in about the same space as your smallest 850 one above. It's very simple:

[snow golem, in a snowy biome] [<Block Breaker] [A couple singularity compressors, powered by reactor itself] [filter for each compressor with a stack of ice] --> [reactor]

That is all. 7 blocks (golem is 2 high), not counting the reactor, and (if you have transformer upgrades on the compressors) just a wire or two, and one or two tubes.

Slap on a thermal monitor, a piece of cobble, and a couple wires if you want it safer.

[epicsquare]

How many snow golems, compressors etc. do you think you'll need to properly cool a 6 chambered reactor.

[gavjenks]

I think snow golems will produce snow once per tick if they can, which would be plenty of snow for a full reactor from one.

Block breakers seem to only be stable down to a timer set at 0.5 seconds in my experience. Maybe faster, but at 0.5 seconds, that is 2 ice per second = 600 cooling per second, so for 2000 EU/tick, youd need 4 block breakers surrounding the golem I guess.

Singularity compressors can probably go faster than a block breaker, with overclockers, etc. Maybe 1-2 of them, I'm not sure, youd have to test it empirically.

Then just one filter per compressor should be enough, since it can move full stacks every half second potentially.

Singularity compressors can get down to one block per 0.8 seconds with the max of 15 overclocker upgrades. In order to spin them up to this speed you require a couple million EU, however once you reach max pressure (15000 psi) they will only consume 3 EU/t each. I recommend throwing some energy storage upgrades in as well to help with the spin up procedure.

Not sure where you're getting your numbers from, but I just tried it in-game, and my watch says 39-40 in 15 seconds which is one ice every 0.38 seconds, actually, at 175,000 PSI with 20 overclockers. Attempting to add more overclockers than that for me made it go negative and fail. But I was able to get up to 20 by adding one at a time.

So that's 789 cooling per second per souped up singularity compressor, or 2.5 of them to run a 2000 EU/tick reactor. So by using 3 you have a nice cushion *shrug*

I also tested the block breakers, and they can go as fast as 0.35 seconds. Which is fast enough to only need 3, not 4.

So you could have a nice in-line operation going.

1 snow golem -> 3 block breakers -> bring them back around (by painting the tubes) so they are next to each other and feed right into 3 compressors -> 3 filters -> all go into the reactor.

So you could fit everything in a 5x5 extension to one side of the reactors+chambers, up to the same height, I think (including cables to power the compressors - as long as you stay at 2000 EU/tick, they can take power straight from the reactor at extreme voltage with 3 transformer upgrades)

Not sure where you're getting your numbers from

Here you go, right from the add-on author's main page. There is a link to the spreadsheet about halfway down the first post. http://forum.industrial-craft.net/index.php?page=Thread&threadID=4907&pageNo=1&s=719cdfb31ff51873674f7b45806107f1a13ee90d

Okay, well thanks for the link, but... in actual testing, 80% of the numbers in your post are still wrong:

Singularity compressors can get down to one block per 0.8 seconds

0.38 seconds

with the max of 15 overclocker upgrades.

The max is 20 at least (I'm no convinced it isn't possible to go higher with EV cable and 3 transformer upgrades)

In order to spin them up to this speed you require a couple million EU

This depends on when you add the overclockers, amount of storage, how many overclockers you end up adding at a time, and many other things. For 15 overclockers, it ends up being significantly less than 2 million Eu/tick, pretty much regardless, though.

however once you reach max pressure (15000 psi)

The max pressure is 175,000 psi, not 15,000.

they will only consume 3 EU/t each.

This is correct.

Either his spreadsheet is wrong, or you interpreted it wrong (one thing I noticed just by glancing at it was that it was a spreadsheet for the macerator, not the compressor...perhaps that has something to do with it). Its always safer to test in game than to briefly skim somebody else's incomplete information.

All advanced machines follow that flowchart. I have rigorously tested a sizable sample of those values. If you have found an error, I would recommend reporting it to the add-on author. Before you do though, check to make sure the values have not been changed in a more recent version of the mod add-on.

Apparently your definition of "rigorous" is different than mine.

The VERY FIRST thing I tried just now to test it with other machines was to take an induction furnace and place a single solar panel next to it. Heated up to 100% just fine, in 500 seconds = 10,000 EU for full spinup + 1 EU/tick to operate after that. Doesn't in any way match the pattern of a rotary macerator.

[warpspeed10]

Use an MFSU for accurate EU difference results. I doubt you reaction time is down to a 20th of a second so that's some experimental error right there.

Also, carry this to PMs, or message the mod author. Don't mention you're from technic when you do though. The minecraft modding community is grossly sick compared to other games, and hold an irrational amount of hate for people for the silliest of reasons.

So, when starting on a new survival world, try to build your base near a good range of biomes, namely swamps (for rubber trees and IC2 crops), and forests (for snowmen to cool CASUC reactors). You don't want to have to worry about transporting an insane amount of ice to your reactor from a distant place. (Although your welcome to try it, it should be fun).

Oh, I thought snowmen only worked in tundras now. Good thing to know they work in forests.

I believe they only work in alpine forests, not regular ones*, in addition to tundra, where they certainly work. Of interest, they die when it's raining.
