1) My little "Big" Reactor. As you can see its actively cooled. That turbine is generating around 7100 RF/t. You can sorta make out in the bottom-left an LV machine hull which houses one of Blood Asp's toys: a wireless redstone receiver. When the central batteries go low, all my reactors are activated by that signal.
2) My RF/EU Conversion Array. Its an absolute beast, and probably cost four-digits of iron (I didn't count). Its converting that RF to EU at 4:1 (x 0.93 percent efficiency). This is the main backbone of my power gen at this time.
3) MOX power. For a good while this little reactor was my main source of power. I'm using a smaller design than I used to, it produces around 700 eu/t but it only uses quad-mox cells, so its easier to automate. Its now a fully hands-off reactor: all stages of fuel refurbishing are automated, I just need to keep a barrel of iron plates stocked somewhere (too lazy to automate that so far)
4) My new happy toy. That's a 5x5 actively cooled IC2 Thorium Reactor to the bottom right. In "passive" mode it generates a mere 120 eu/t (albeit extremely efficiently). WIth that crazy tower on the left, its closer to 450 eu/t. You're looking at 10 Liquid Heat Exchangers feeding 10 Stirling Generators, each of which is capable of outputing 50 eu/t (but we're falling a bit short of that in heat output).
This would be even more output if I converted that heat into superheated steam instead. This was structurally simpler to do. I may switch to superheated steam when Blood Asp fixes up the Large Heat Exchanger and Large Turbine
Edit: I forgot to mention that at 450 eu/t, this thing actually generates 450,000,000 eu per 16 thorium. And then you get some of that thorium back at the end of the cycle. 450 eu/t isn't a lot, but its insanely efficient. I'd build a couple more of these, but you wouldn't believe the quantity of raw resources I had to dump into it.
5) My new power storage facility. Ignore the gas tower in the back, I haven't used that in weeks. Everything's now in that 9x Insane Voltage battery buffer. It currently has 6 batteries in it, so 600,000,000 total eu capacity. The cycles to deplete/fill this thing take loooooong, which is good for power sources such as Big Reactors which have long spin-up times (and therefore run more efficiently if run over a longer period of time.)
All the junk on the floors/pillars is some blue-power and automagy redstone logic to switch the power on and off. This is all possible because Blood Asp made the energy detector cover absolutely amazing: it now reads energy stored in the batteries inside.
Old-fashioned redstone dust is mostly used because Blue Power and Automagy don't talk to each other nicely. I bridge them with redstone dust.
