This is very neat and battle-tested design. Connect uranium processing output to the bottom belt and iron plates to top right chest and you're all set.
- compact and neat
- autostarts
- it won't get stuck unless you don't have storage for uranium cells
- it may seem slightly imperfect but it has self-compensating property that will endure even heavy abuse
- eco-friendly but you can use any modules
- buffer chests for everything
- easy to expand to the left, easy to shrink from the left
- no beacons (I don't like them), but you can add if you want
- no overcomplicated circuit network
Enjoy!
