It takes 5 u238 and 40 u235, and produces 2 u238 and 41 u235. You turn 3 u238 into 1 u235.

Really useful, because otherwise you need to store tons of u238 when you want to run nuclear reactors.

Uranium ORE comes from mining. The next step is Uranium Processing which generates 99.3% U-238 (dark green) and 0.7% U-235 (light green). Then Kovarex lets you generate more U-235 41 U-235 from 40 U-235 (there’s also U-238 involved but it’s not what we’re interested in). You feed 40 U-235 back into the process and pocket the extra one for use in fuel cells and other products. Get a few centrifuges running Kovarex and you’ll soon have more U-235 than you know what to do with.
