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. ;)
