hmm, looks like an good design exept for one thing.
do you know that the ice feeder wil fill every empty inventory slot inside your reactor?
i dont know if you calculated that part in?
It produces exactly 300 heat (I fill in extra blocks so it doesn't get extra cooling) and it gets 1 ice per second thanks to the sequencer. This keeps it stable at about 10024. I'm not sure why, but last night this thing melted, so I'm going to have to figure that out.
Also, thanks for the praise. I'm working on an even bigger design now that I have a semi-stable breeder.
EDIT: Figured out the meltdown thing. I pushed this reactor to 13900 heat (to see if it breeds faster, it doesn't ) and during the cycle somewhere I'm assuming it missed a piece of ice and went to the melting point, but then turned off. I'm sure it just slow trickled from there and eventually melted down, as I had lost a LOT of bricks from the meltdown, but in my testing of what would happen in a meltdown situation it only usually killed 4-8 (through lava, the explosion was too weak because of all the reinforcements from plating and such). Lesson learned, you need the 101 on the last counter (I had set it to 100 before bed) to fully finish the cells off so it doesn't melt on you.
