I love your mod! I'm very interested in nuclear power, and the details of this game are much more satisfying than Extreme Reactors. However, I'm a little confused with some of the mod mechanics. While I was using my reactor, I started to build up depleted fuel. I started to reprocess it, and eventually came up with some MOX-239. This fuel was too hot for my reactor, which was using a combination of redstone and quartz coolers, 5 cells, and 4 graphite moderators. I had heard that active cooling could solve my problem, but every attempt I made ended in disaster. With about 24 active coolers running on water, they dissipated about 1000 heat. With buffers, water pumps, pipes, and servos working together, this just wasn't worth it. My redstone and quartz coolers provided more cooling for about the same cost (not including the additional equipment), and were much simpler. With the added complexity and cost, I can't see any reason to use them. As for other materials, most of them proved too expensive, I decided I would just have too build a bigger reactor. I'm trying to figure out if I'm missing something, but I didn't find any answer of solution.
