[Stable Nuclear Reactor]

My setup is the way it is for one reason, flexibility. I can do breed and run both in the same housing.

Something else to note that EMC doesnt work the same way as the past. Quad and Dual rods, if I'm not mistaken, don't turn into near-depleted cells, thereby removing your chances of breeding it back.

You can take 2 uranium, turn it into 1 uranium cell, then turn the other into 8 near-depleted cells. Using the first cell, breeding 4. Again, with my setup, you can run it as full reactor at 240eu/t, or run it in breeder mode with 160eu/t with no changes whatsoever (with the exception of rod placement).

Also be careful with those thermal monitors! You can invert their output by clicking in the area below the readout screen (the hatched area with change when you do so).

I only use EMC as a value as it's a good indicator of "cost" to build. You could also use UU-matter as a "cost" radar, but EMC is easier.

And I understand the hybridity of your reactor, very effective for a single set-up. But it's better (i.e., more cost-effective uranium wise) to have a dedicated breeder reactor, Mk II or higher. Depleted uranium "cooks" faster if the reactor is hot. Not ideal for a main reactor, since it doesn't produce a lot of energy, but better as it takes less uranium to breed more re-enriched cells.

For example, this Mk II breeder that I found on the IC2 forums breeds 4 cells roughly every 2,000 seconds. Meaning if you set it on a timer, it'll breed 20 re-enriched cells for every uranium you put in. Plus it doesn't have any cool-down time, so theoretically you should be able to run it even after it's hot for even greater effect. It's an absolutely ingenious design, props to whoever made it.

And even still, your reactor is very expensive to build... Let's see if we can have the same effect but cut down on costs.

This one's not bad... But it doens't seem to work with an all-uranium set up. Let's fix that.

This one works, it's fairly inexpensive. But it's still very overkill. We can do better.

There we go. And about 160,000 EMC cheaper than your original.

Pro-tip: Don't use diamond heat vents if you can help it. They're expensive, and gold ones are better in almost every way. ;)

Loki, Thats an awesome setup for a reactor.

May I suggest this reactor setup. Very little resources (and work) involved. No need to change anything and can be adjusted based upon power demands. I literally just sat here and put patterns into the planner to see what would work. I came up with this

http://www.talonfiremage.pwp.blueyonder.co.uk/v3/reactorplanner.html?21p7gt3oo8zzh3xs52kwuibx00frvnrv7neurs00qsn5hli5a5p8ewirm4nszuwar8jwrtm0cmess8w

Very little resources, costs 450,000 EMC to build? Try this one:

52,000,000 EU/cycle (260 EU/tick), Efficiency 4.33, 340,000 EMC to build, 10,000 EMC to run.
