I'm about ready to dive into nuclear power. Where is nuclear power and this part of the tech tree on your roadmap? If there are going to be big changes pretty soon, I might hold off.

0.3.12 has now lots of changes for nuclear power. I will push this version on Friday. However I am pretty sure, some things will change when the mod enters Beta phase (would guess after like 0.3.25 - 0.3.30).

Glad I asked. I'll hold off until Friday.

Is Kovarex intentionally locked behind space science? With most (all) of the nuke tech recipes requiring both uranium isotopes, you need a substantial amount of U235, which means a massive enrichment setup and tons and tons of U238. And you are stuck with this arrangement for quite a while.

Not a dealbreaker. I have a bunch of centrifuges plugging away and I can always build more boxes for U238 (or throw it in the lava). Just curious.

I will change space science tech branch in the future. I gues kovarex and other stuff will be unlocked before launching the first rocket but i currently have no specifics planned.

Sounds good. What's next on the roadmap? Comp sci? Getting near the end of second tier of science!

0.3.13 cryogenic science and computer science
0.3.14 fix melting and casting recipes
0.3.15 vulcanic rocks -> getting recoures that are otherwise difficult to get (Currently unshure what is needed since i still have not played after automation science 2)

As far as difficult resources, at the point I'm at cerium and iridium are the only significant bottlenecks. Palladium, gold, and silver I get in sufficient quantities with pretty big crusher farms. Lanthanum and neodynium I haven't needed yet, but they are comparable to cerium and iridium because they come from the same enrichment process.

Oh, as far as power, I set up heating towers with heat exchangers and steam turbines and that has provided more than enough to the point that I never felt the need for nuclear reactors. Between mining productivity research, big mining drills, and belt stacking, coal plus heating towers provides plenty of heat.
