It's been a couple years since I played IC2, and there's been at least a couple months worth of development progress since then (kidding, kidding... sorta). The new reactors got me excited, so I've been playing with heat reactors, trying to find a way to maximize the heat output of a low-maintenance core. The basic requirements are: no replaceable parts besides the fuel rods and neutron reflectors, and low meltdown risk. The best I've been able to do so far is a consistent ~750HU/t, translating to about 525EU/t through superheated steam. The reactor planner (v3) doesn't seem to accurately report heat vent output, but here's the layout:

These will run with zero chance of any of the parts melting. Is there a better way to squeeze more heat vents in there? Mathematically I have too many heat exchangers and not enough vents, but due to layout constraints I couldn't find a better pattern.
I've got the system setup using a number of other mods - nuclear control, pressure pipes, and project red - but I think this should be usable in theory with vanilla redstone timers and vanilla IC2, if you're a real masochist. Could put quad uranium rods in it for better efficiency, but I don't want to risk a meltdown if lag/chunk loading issues cause problems with the regulation system (which happened in my tests). You could also replace the neutron reflectors with heat plating for lower operating costs, but thick neutron reflectors barely put a dent in my resources. I'm not sure why everyone complains about their expense.
I have a couple questions/complaints I haven't been able to answer due to lack of documentation or impracticality of setting up experiments.
First off, is there any reason to run a boiler setup with anything other than exactly 2 liquid heat exchangers at exactly 1mb/t, 220-221 pressure? I can't figure out the point of even having settings on the boiler, since it only appears to work at very precise settings with what appears to be completely arbitrary math and a completely opaque GUI. Why even have a range of 0-300 pressure and 0-1000 mb/t when no other settings do anything useful (other than the similarly singular optimal design for distilling, which appears to be 60HU/t, 100 pressure, 1mb/t)? Why not just have a steam & superheated steam setting? Trial and error with 300,000 possible combinations isn't a game mechanic.
Second - distilled water generation - in order to have enough distilled water in circulation it seems incredibly impractical to use vanilla IC2, and impractical in general to generate distilled water. It's slow as dirt to create, for one thing. A two-boiler setup with electric heat generators outputs a measly 200mB/t for 400EU/t, which took something like 4 hours to generate enough to keep the 4 boilers from the reactor filled. This made boostrapping to a 5x5 reactor from wind power unnecessarily costly and time consuming, especially with the boilers fighting for power with the refinery (macerator+washer+centrifuge, OMFG slow and expensive). Solar distillers are basically free, I guess, if you don't want a useful amount of distilled water.
Furthermore, every time the reactor goes down and comes back online again the (apparently cosmetic) initial puff of steam as the boiler begins producing superheated steam causes leakage. In the end, I just ran fresh water through the reactor boilers till I filled up a huge tank as a buffer, then switched them to distilled after clearing calcification from the boilers. This would be impractical with vanilla IC2 due to lack of pipes or tanks. Is there a less stupid way to do this that I'm overlooking, or is it basically just "not finished"?
Kinetic steam generators: I was initially running one turbine-turbine-condenser stack per boiler until I stumbled on the fact that the turbines can handle a practically unlimited amount of steam (maxing out around 4000EU/t output for ~6000HU/t input in my tests iirc, using an infinite superheated steam supply). This isn't documented anywhere, and there's apparently no efficiency cost for pushing lots of steam through a single turbine stack vs. running multiple stacks. Am I missing anything?
Steam turbine blades: OMFG, expensive. When I was running 8 kinetic steam generators it took 4 (!) blast furnaces in continual operation to keep up with refined iron demand (27x refined iron per blade x8 for about 1 full cycle worth of blades). Total cost to run the furnaces was ~90 EU/t (counting compressors to keep air canisters circulating). I didn't work in the cost of running the refineries since they're always producing, or the metal shapers for rolling the plates. I can't find any info on the wear equation for turbine blades, and they wear too slow to do an A/B test. Do they wear out based on flat operation time or an RPM-to-time basis? If the latter, should be way cheaper and more sane to run a single steam generator stack for cost reasons as well. If the former, the cost and production needs are the same, which means 5x5 reactors are not as efficient as they appear (a flat requirement of continual 90+ EU/t consumption for blast furnaces is ~15% of my reactor design's output, cutting its total efficiency).
---
Overall, this is pretty cool compared to the old system and puts nuclear farther into the endgame, complex engineering bracket (where it belongs, IMHO). I can't imagine doing this without fluid pipes and tanks though, and without redpower/project red and wireless redstone I'm not sure I'd have the patience to build the control system.
OTOH, wind generators are now crazy powerful, and I kind of feel like other than the larger space needed for a wind farm, they're now more cost effective and maintainable than nuclear. Carbon fiber blades are practically free unless you're burning coal for some reason, and scaffolds make raising a windmill to a reasonable height pretty trivial. So why not wind? The only answer I could come up with was "because it would be fun" and "eventually free energy with the plutonium pellet things".
Or I guess you can just make basic EU reactors.
