AE isn't going to work, because it is too slow to react. You're going to have huge heat spikes everytime a condensator is swapped because the importing, repair-crafting and exporting operations are going to take 2-3 reactor ticks instead of 0-1 as in the case of golems with fabricators.
You're also going to have difficulties with the damage values. The golems allowed Direwolf to exactly target 80% damage remaining (since each lapis restores 40%). AE doesn't let you do that, especially not in 1.4.7. In 1.5/1.6, you have the reworked fuzzy buses that can target 75%, but not 80% specifically. Also, the AE autocrafting recipes for adding two lapis in two steps are probably not going to work, because the autocrafter doesn't pay attention to damage values.
Finally, that reactor design was made for show value and isn't actually very good. It's extremely expensive to build, has massive running costs and is fairly unsafe. There are better designs out there, try looking around
here.
