Uranium re-enrichment in experimental?

Plutonium (more importantly MOX) acts as a more logical recycling route than the breeders did, there in an incentive to run reactors for it compared to breeders that could have near depleted uranium cells crafted directly. There's a bit more reliable realism in the process too as you always know you'll get plutonium from spent fuel rods over the 25% chance of uranium cells flipping to depleted isotopes. Currently Lithium -> Tritium acts like the old breeders did for the sake of having a conversion process but whether that stays or not will depend on a couple of other factors.
