1: yes, 2 fluid ports (one cold coolant in one hot coolant out) + liquid transport mod. i use extra utilities because of its immense flow rate if properly configured and upgraded (well over 8000mb/t) and good reactors need immense flow rates, although for the usual badly configured pissant little 1 efficency mark 1 reactors people love to make something like buildcraft or tubes mod might work, ic2 has its own fluid transport methods now but they are very clumsy, resource heavy, and honestly not worth using at all
Thanks for the suggestion, I'll try out some of these mods. I've never really liked how slow build craft tubes are so it's good to know there are a lot better ones.
3: learn to forum please. dont necro 2 month old threads with an innane and easily answered question. if you had read the nuclear engineering subforum and looked at a couple of threads you would have your answers much earlier than me replying.
Sorry about necroing the forum. I had done a bit of searching and it was late and I just replied to the first i found... I'll do a better job searching next time. That said, thank you for taking the time to answer me.
