Alvearies with 16 frame housings.. only way to make those tolerable the MFR Laser should still be able to fuel itself with leftovers, but might need few a yellow lens. Most of my base runs on solar, but I have the reactor hooked in as a backup. It idles at 650 rf/t and consumes only 0.009 mb/t so it's not bad.Honestly, the Big Reactors in this pack leave me a little underwhelmed. I made a relatively small one (12 fuel rods at 5 blocks apiece), but the Yellorium generation is painfully slow. Cyanite and Blutonium are even worse. Maybe if I set up an Ender Quarry in the Deep Dark, I might have a chance of keeping one reliably fueled. As it is, I'm still running everything off of solar.
