When I port the map I am working on to 1.4, I will deploy a 10440 EU/t nuclear plant. I'll need a lot of help keeping it fueled though. Maybe I can employ some of the spambots.
hmm.. if there's nowhere else for the cells to go (like the only empty spaces are where the cells go after they're removed) than logistics pipes may work.
You'll need a chassi pipe mk1 and a supplier pipe connected to each reactor.
Inside the chassi pipe goes an advanced extractor mk3 set to remove any depleted cells. Then the supplier pipe is set to supply the correct number and type of cells. You'll obviously need a few autocrafting tables with crafting pipes and associated supplier pipes (or modules) to support this.
edit: redpower would of course work as well but i'm only mentioning stuff that works now.
