A modified design based on KatherineOfSky(https://www.youtube.com/channel/UCTIV3KbAvaGEyNjoMoNaGtQ)'s uranium setup. Original design : https://drive.google.com/drive/folders/0BwVHGs2mds_XRUVCekwxYnNldnc
Fixed the problem of outputting more than 1 U-235 after each enrichment, which requires excessive U-235 in order to work stably. Integrated train fuel ,reactor cell, cell reprocessing into one block.
Consumes two full blue belts of ore. Produces 100 U-235 / min, 30 used to make nuclear fuel & cell, gives 70 spare.

v2 Update: Fixed U-238 jams belts which causes no U-235 input
v3 Update(10/12/2020): Removed old pipe remnant. Thanks to Factorio forum @foamy for pointing it out.
