I've created this pretty decent reactor design using 6 quad thorium cells and 3 plutonium cells (4.63 efficiency, 512 EU/t). However, I am having problems cooling it. I have gotten extremely close to stabilizing it (12 excess heat) with this design, but I cannot get it to 0. It is extremely frustrating knowing that this nice reactor is so close to being possible. Are there any nuclear reactor wizards around here who can make this happen with only heat vents and exchangers?
