The existing 'budget breeder' auto pilot does not work. Maybe it worked earlier, but in 109 there is too much cooling.
I tinkered with the design to get it working for 16k-22k temps. Stack the two lava cells to 16 to 22 (25 if you got balls of steel) and it will hold that temp even empty.

Calculator says 7x, so guess that is 28 or 35 cells a cycle. NEI not working with isotopes to test.
Heating configuration: Autopilot 2x lava stacks
Cells charged per uranium cell: 28? 35? will depend on where you are in the 16k - 22k heat range.

Edit:
Cool feature: I found it fails gracefully. Works up to 25 lava cell stacks... with some fires in the area
It runs very close to redline on the reactor heat exchanger parts. Bumping the lava to 26+ just breaks the heat exchangers and the lava stops affecting the reactor and it cools itself down.
Edit 2:
Same concept expanded for efficiency:

Cheaper than the current #2 breeder (no diamonds), and heats up faster. Same as above you can leave it on and empty and it will just hold the heat at 31k-64k depending on what you set it to.
Heating configuration: Autopilot 31-64 sized lava stack
Cells charged per uranium cell: Heat range 31-64k = 10x - 21x recharge speed.
