Well, I'm just a noob messing around with IC2's Reactor Planner, and i just ended up trying to make a breeder. Im not all that hot on how well the other breeders work on the first thread, but after looking at them, they kinda seem like they get hot. Well, I beleive i figured out a better alternative, something that will never over heat, and it will re-enrich 4 cells at once, using one uranium cell.
Heres the design: http://www.talonfiremage.pwp.b…s8g445ugdfjs8nliro3qhoj5s
Tell me what you think! Thanks 
EDIT/ADDON: I just made a new one, breeds 6 cells, full use: http://www.talonfiremage.pwp.b…buq14b9ajot7y1gt4e16bas5c
