I need a decent reactor design that produces a good amount of EU, is relatively cheap and requires minimal maintenance. I'm currently on the Mindcrack Pack. It's been a long time since I dabbled with reactors. What has changed? I heard that there was a big heat change? And judging by some reactor setups people posted there are a lot of new items. Also, how should it be wired? Does it still produce EV, and what block is best to surround it with to block the explosion if it does explode?
