but i have tried to run it full cycle, reflector and uranium finished at the same time
breeder can rechage damaged uranium right?
but how can i rechage a dual-uranium cell?
Dual breeder isn't recharging a dual cell, its recharging 8 depleted cells at once.
It burns copper faster because of how much copper it uses, 200. You'll get about 9 uranium and around 200 copper off running a miner to bedrock. So you burn the copper, you burn half a uranium (with the breeder) and now you're out of copper for the other 8 and a half uranium.
