Yeah I mostly compared the reactors to for example a RC boiler and engines in my head and realised how much space the reactors were taking up in comparison. But then again the boiler usually requires additional infrastructure(like woodfarms or ethanol production). So might not be totally different. But still if you compared the boiler running on coal compared to a reactor, power/space density is horrible. But is is damn easy to run in comparison.
Also, space is infinite for me, since I've caving it this time (I carve out the space I need).

Question: when folks refer to actively-cooled reactors, are they just talking about hooking up to a steam turbine or something?

Yeah. Actively cooled reactors is when you add Coolant ports to your reactor and hook it up to a turbine. You will then need to supply it water(turbine can condense the steam and the water can then be used as a closed system).

But other than the Coolant port you build the reactor EXACTLY as before.

Any point to (or possibility of) doing such with my micro-reactor?

Yeah very small reactors can potentially output large amounts of steam. The deal is to find a level of steam output at which you are satisfied with the fuel consumption and then design your turbine around that. But ofc larger reactors will run the system at greater efficiency.(you might build a reactor capable of outputting tons of steam and then only use a fraction of it just to get the high efficiency of the bigger reactor. A single 7x7x7 reactor can at default setting output something like 600000RF/t through turbine I think, but you might not want to due to low efficiency of high temperatures).

I would recommend that you set up a copy of the reactor in a creative world. Then set it up with coolant ports, feed it water(dont know what means you have of this, but for this testing you will need to pump large amounts of water in), let the steam out to some kind of fluid void thingy. Then dial in the control rods till you are happy with the fuel consumption and read out the steam production(make sure you dont bottleneck the output of the steam).
Take this steam value and look up this spreadsheet:
https://docs.google.com/spreadsheet...TUxOUGxMRlpERWtPMmtGT213bmc&usp=sharing#gid=1
Make sure you are on the second tab: "Coil setup Numbers"
In your case your best Coil material is gold, so scroll down to Gold. Now find a steam value that is close to the one you read on your reactor in either the high speed or low speed column. You are going to have to go with this exact steam output so make sure your reactor can output the one you choose. You can then see how many blades and how many coils you need to build your turbine with for it to run at the optimal speed at that steam output!

Example
Lets say you read 497mB/t steam in your reactor at a decent fuel/t setting(make sure you are under 1000C). You then go to the spreadsheet and find that there is a 508mb/t at low speed and a 506mB/t at High speed.
Now you can see that the power output is pretty much identical, so is the blade count: 22 blades. But the main difference is in this case the number of coils: 4 coils at low speed, 2 coils at high speed.
Now it is obviously optimal in terms of material cost and space required to choose the high speed option and build the 2 coil, 22 blade turbine and feed it 506mb/t of steam and let it run at 1800RPM.

Oh in addition to my previous post about turbines:
Transferring the steam from the reactor and to the turbine and the water back again can be a bit problematic due to limitations in Fluiducts etc. People tend to use Tesseracts which works just fine with no throughput restrictions, but the simplest solutions is to just build the reactor and the turbine adjacent to each other and have the coolant ports aligned up for direct transfer. Just build the turbine first, configure the ports, then build the reactor and configure the reactor ports(reactor ports can be configured while the multiblock structure is not formed, turbine ports cannot).

that works with smaller reactor
But some of us like to power 4+ turbine/reactor :3

This won't be a problem for me; I just disabled the recipe of coal->graphite (I assume that's vanilla)

I now get 1/9th of a graphite per coal. And coal is valuable in many other processes in my GT game.

Go, quarry, go!

I believe you can convert Charcoal to Graphite, unless that recipe has been disabled.
I didn't see a charcoal->graphite recipe, or I would have killed that one too :p
You might want to triple-check that one. I didn't see any bigreactors minetweaked recipes at all, except the ones I added.

*Edit: Maybe its a config? I didn't check that.

It's configs :l

Yep, BR has configs to adjust it's recipes a bit. I also disabled the charcoal to graphite. I'd rather there be a use for Coal.

I spent an hour last night trying to teach my furnaces to smelt coal differently. I'm starting to suspect the hard part (removing the coal recipe) I could have just done in the configs.

Woops.

Guys, I see that if I feed one yellorium into the reactor, it only works at 25%.

Is this actually less efficient, or is it just slower production? I suspect its the former, and if so, then what's the best way for me to test the total net output from a single yellorium ingot?

The fuel rods hold 4 ingots worth of fuel each. You have to fully fuel the reactor and divide by the number of ingots to calculate each's contribution.

Dunno if anyone's mentioned it yet or not, but mingling Big Reactors and RotaryCraft isn't a bad idea. A RoC extractor can process yellorium (or any other form of uranium, if you've got the OreDict config enabled for BR) with a reasonable investment and water supply. An average of about 5 ingots per ore, you can really stretch your ores out.

does anyone know of a good way to quickly produce cyanite? I want to try and build some turbines as soon as possible but it's going to take ages before I get enough cyanite for it...

I would guess a 3x(high number)x3 reactor running at high temperature feeding a MFR laser drill would be the best bet due to its low efficiency.

Or you can process your Yellorium ore in the EnderIO SAG mill for the 5% chance for a bonus cyanite dust.
