Rather than going for raw power output, I tried for efficiency. In the Optimal Reactor List, only ONE reactor has an Efficiency higher than 5... and while it does hit an Eff7, it only produces 140 Eu/t and a total EU output of 28m.
I wanted to do better than that...
Now, a simple one-chamber ractor can crank out something like this.
960 Eu/t, Efficiency a whopping 6.0, and a total EU output of 192m.
Only problem is that it has a micro-cycle time of just under three minutes. Not cool. However, there is at least partial compensation here...
Our Turbo V6 Cooling Tower can handle 24 cooling cells. Which means one cooling tower can handle three such cycles. Still, at just under 3m each micro-cycle, I'd STILL need about 8 Cooling Towers to keep up with cooling. And that comes out to only 120/tower. Not good enough.
Let's see if we can do better still...
If we employ GregTech Helium Coolant Cells, worth 360K cooling, we end up with a micro-cycle of just under 18 minutes. Normally, that wouldn't really help us, because the time it takes to cool them back down is also multiplied six times, but now we've managed to get 10% of a full cycle in a micro-cycle. So now we only need 10 micro-cycles per cycle rather than significantly more. And at 3 micro-cycles per cooling chamber, you'll only need 3 chambers to complete a full cycle! This brings our effective power generation up to 240/generator, so we've beaten the 7 Efficiency tower in terms of power per tic output, and we've got -way- more total EU per cycle.
But what if we wanted to do even better?
Thorium is an interesting fissionable material. While it produces less EU/t, it does have the advantage of also producing less heat per tic, in exchange for a longer run time. So lets swap out the Uranium for Thorium and see what we get.
At nearly 12 minute cycle, using standard 60k cooling cells, our cells cool off in roughly 6 and 2/3 a cycle. Which means only two or three cooling towers are needed. Of course, the 192 EU/t is fairly lackluster for such a system, but it's got an efficiency of 6 and a total output of 192m. It's designed more as a workhorse reactor, producing a constant amount over time, with a high efficiency rating one would expect from a long-term reactor.
Helium cells wouldn't change these numbers much, unfortunately. Because Thorium runs 5x longer than Uranium, even the very impressive 71.5 minute micro-cycle time would still only represent about 1/12th of a total cycle. So again, you'd need about three cooling towers, just to be safe, and your cooling cycle would hit before your end cycle would. However, it would cut down the number of micro-cycles by a factor of 6, so that's probably worth it, considering Helium is generally a byproduct of producing other materials.
So, let's see if we can do even better...
Plutonium is a high-energy fissionable material which is a royal pain to produce. Which means you *probably* want a high efficiency rating out of it. Unfortunately, it also produces an insane amount of heat buildup. So lets see if our system works well here...
Using the same setup of 8 quad-cells flanked by 8 cooling cells and a couple of reflector plates to bring up the efficiency to 6, we see a rather disappointing micro-cycle time of 80 seconds. Since Plutonium has twice the lifetime that Uranium has, you're looking at two HUNDRED fifty-ish micro-cycles per cycle... yeesh. However, we're -only- looking at a stunning 62.5 microcycles in a cooling cycle. That means about 20 cooling reactors.
Having said that, you are looking at 1920 EU/t, so comparable to old-school CASUC level power generation, and Efficiency of 6, and a total EU output of some 768m.
Now, Helium cells will reduce the number of micro-cycles per full cycle by a factor of six, meaning suddenly you're only looking at a total of 42ish cycles. Which means only 14 cooling towers needed for a full cycle.
There's another advantage to this system that I wasn't leveraging with previous designs. As i am only utilizing 8 cells in the active reactor, I can use a filter and a retriever with a total of 8 cells, meaning I only need to pulse them once to get all eight to transfer. This means that Bumbster's setup is more than enough, if he just adds a few more cooling towers to his design.
It's probably not the most cost effective method yet, but it's at least quite efficient
