- Alter the recipe from cooling cells. Instead of making them craftable with water cells and tin, make them be craftable with canning machine (snow/ice into cells) or compressor (water cells -> cooling cells). Upgrade to 30k and 60k could work with crafting though.
Sounds good, especially considering the fact canning machine is ... kind of useless for now ^^. Also, as you mentionned it above, I also agree coolants cells should be way, way buffed. For now they're just sorts of UP Gold Vents ...
There should be no stage of "well, I got endless EU now, I am done with energy generation forever now."
Yup. That's something that can be done, with reducing every Output from greengens in the config ^^. And GregTech help.
Add "reactor" (maybe "Reactor Component") into the description of all components, so you can find all of them with one word in the NEI.
Why not. That sounds feasible, and useful.
In a more general way, buffing Nuclear Reactor has been oversuggested already, but I still agree with you. However, an easier way to do so, is to use GregTech, reduce Greengens output and to disable any CompactSolar/Advanced Solar Pannel ^^.
