[0.15] Uranium enrichment process
This is my first uranium processing layout. On the top is uranium ore processed to U-238 (and rarely U-235). In the bottom is the enrichment loop (Kovarex's enrichment process). When the loop has more U-235 than it needs, it overflows U-235 to uranium fuel cell processing facility. It recycles used up uranium cells.
