Before I start, this is not a "I hate the new reactors" thread.
With all the changes to reactors, i think there is only one thing that could make them better (in my opinion). Real Neuclear Reactors need a constant supply of water to help keep them cool. By using a pump, you could fill a internal tank to help keep the reactor cool, increase the speed of cool down and add a sense of realism to the reactor. You could also add compatability for Buildcraft/ Red Power 2 liquid pipes and create a mechanic that could make the "I want CASUC's back now!!!" people. If you add in your own way of transporting liquids, you could also make them require power to run (if you do, can you make them so that they cannot use neuclear power under any circumstances?) Opinions, anyone?
