Based on the Design of Cyber Garret (or vasek7 ?) https://factorioprints.com/view/-KjmRXj1uY-0VKIPzJuB
This Facility takes Uranium Ore and processes it to Uranium 235 and 238. It holds all 238 until all 3 Kovarex Enrichments of that side are running without interruption. When the Belts are full it triggers Uranium Fuel Cell production. If all belts (enrichment and Uranium Fuel Cell) are full, it triggers Nuclear Fuel production. Nuclear Fuel Reprocessing is Included aswell.
If Uranium 235 gets too full in front of Kovarex it gets dumped into a provider chest and put back on the belt when the kovarex output is clear.. If Uranium 238 from processing starts to pile up and it cant get to the enrichment belt, it gets sorted out and put back in further ahead with a buffer. Same for Uranium 235
There are 2 Blueprints. One is Vanilla and one is with Warehouse and Loader mod.
I admit that it is totally overcomplicated.
