Replaces the vanilla nuclear fuel cell with three new fuel assemblies.
- Natural uranium fuel assemblies are the first type available and are made from uranium, carbon and steel
- Mixed oxide fuel assemblies are part of a breeder fuel cycle and allow you to use nuclear waste and depleted uranium as fuel
- Enriched uranium fuel assemblies require the player to unlock centrifuges on Aquilo and produce uranium hexafluoride for enrichment

Depleted fuel assemblies can be reprocessed into new resources. 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. Mixed oxide can be further refined into plutonium, which is useful for powering portable fission reactors (which are now placeable as buildings) or breeding fuel from depleted uranium with mixed oxide fuel assemblies.

Also included are nuclear cannon shells and nuclear artillery, unlocked with an end game technology.

This mod should be compatible with existing vanilla save files, it does not require generating any new ores. Save file backups are still advised.
