Extract Pu-239 from depleted uranium fuel cells and use them either in MOX cells, in which they substitute for U-235, or use them to create breeder fuel cells, which produce more Pu-239 than they consume.

Use either U-235 or Pu-239 in atomic bombs. Since the critical mass of Pu-239 is about 1/5 of U-235, so is the Pu-239 cost. (This is scaled to the increased cost in Space Age, if Space Age is active.) Since Pu-239 is much more trouble to get, this is plausibly balanced.

Kovarex enrichment is disabled by default, but may be enabled via mod settings.

This mod was created as an update of the Nuclear Fuel mod to 2.0, with some changes and streamlining, and uses graphics from that mod. As compared to that mod, the plutonium fuel cycle is both buffed (breeder fuel cells' energy content is scaled up to be proportional to the net fissionable material consumed by burning them), and nerfed (the breeding ratio is reduced to a more plausible 1.5, and the MOX fuel recipe does not have double the U-238 efficiency of the U-235 recipe). If you desire the faster burning behavior of Nuclear Fuel's breeder cells, this can still be accomplished by burning them in single reactor setups without neighbor bonuses.

Uninstalling

If Kovarex enrichment was not disabled, this mod can simply be disabled.

If Kovarex enrichment was disabled (default):
- Enable it in mod settings.
- Load and resave your save file.
- Disable this mod.

Check out my other nuclear mods:

Deterministic Uranium Enrichment: Changes the uranium enrichment recipe to be deterministic, multiplying all recipe parameters by 1000 to maintain the same cost, time, and output ratio.

Nuclear Power Rebalance: Rebalances solar and nuclear energy values to make nuclear energy realistically overpowered.
