A full overhaul of the nuclear production chain. Start fueling your reactors with natural uranium on Nauvis, shoot the nuclear waste into space and reprocess it into useful materials.
- Radioactive raffinate is a liquid suspension of all the fission products that are no longer useful for nuclear power generation, but it is a new ingredient for space science.
- Plutonium cores can be crafted into portable fission reactors, which are also useful as stand-alone nuclear reactors or very fast train fuel. Or turn them into nuclear bombs.
- Depleted uranium ammo can bring you all the way to Aquilo, by being able to break large asteroids.
Once there, setup reliable logistics to deliver uranium for cryogenic science packs. The research from Aquilo will let you build better space platforms and produce more efficient nuclear fuel for your reactors, among other useful things.

Each planet now has one paired research with every other planet, some recipes have been changed to accommodate that.
- Mech armor is a gleba/fulgora unlock and requires carbon fiber instead of holmium plates to craft
- Stack inserters are a vulcanus/gleba unlock and require tungsten carbide instead of processing units to craft
- Rail support foundations unchanged as vulcanus/fulgora unlock
- Nuclear artillery is the vulcanus/aquilo unlock
- Captive biter spawners are the gleba/aquilo unlock
- Legendary quality is the fulgora/aquilo unlock

Fusion reactors require promethium science to unlock and fusion power cells have a completely new production chain.
