This Facility will Supply you with all of the U235 and u238 you will need for Uranium production, Nuclear fuel and Nuclear weapons in Excess. The Facility also contains a nuclear fuel reprocessing site.
To overcome the common problem of Excessive u238 production and no way Disposing of items in game (Except from shooting containers) I have incorporated an inner sushi belt that only allows on Uranium 238 onto the belt if the circuit reads a section of the belt as being empty, it is then filtered onto one side of the belt allowing the Kovarex plants to dump U238 unhindered.
Any U235 that is generated within the centrifuges is automatically accepted onto the sushi belt on the Kovarex output side but will be quickly picked up freeing up the belt again.
*Update, adding Uranium based Ammo production such as Gun ammo and cannon shells will remove excess U238 during the process allowing the production of sufficient U235.
