Just a small observation - on the Mass Fabricator page, it says scrap improves the process by a factor of 6, while on the scrap page, it shows a factor of 8. Which is correct, and could someone with powers please edit the wiki accordingly?
The problem I see with most of the perfect breeder reactors in this thread is that they are completely dependent on water cooling to maintain equilibirium, and at the higher heat levels that breeders work best at, water evaporates rather quickly. How do you guys compensate for the possible melting of water source blocks nearby the reactor, which would naturally destabilize the system and cause a rather large explosion if left uncorrected?
A couple of my own (This will get updated from time to time):
Class 1 Breeder, 10 EU/t, 3.00 efficiency:
Class 1 Breeder, air cooled, 5 EU/t, 5.00 efficiency:
(We don't need no water...)
Class 2 Breeder (Just barely qualifies), 10 EU/t, 5.00 efficiency:
