Changelog

Version: 2.0.11
Date: 11.05.2026

Version: 2.0.9
Date: 03.05.2026

    - MOX and enriched U. fuel assembly recipes changed to use fluoroketone/water respectively
    - MOX fuel energy increased from 80GJ to 800GJ
    - MOX rods recipe changed to use nuclear waste and thruster oxidizer, recipe locked to space/aquilo, uses more plutonium
    - Enriched U. rods recipe changed to use ammonia instead of water, locked to aquilo
    - Depleted fuel assemblies, nuclear waste and empty/contaminated portable reactors recycling recipe removed
Version: 2.0.6
Date: 21.04.2026
  Major changes:
    - Removed more single use items (highly enriched uranium hexafluoride)
    - Uranium core recipe changed to run directly in the centrifuge, taking a lithium plate instead of brine
    - Uranium hexafluoride uses ammonia instead of water in its recipe, changed its crafting time to 5 seconds
    - Cryogenic science pack recipe changed

  Minor changes:
    - Left the vanilla nuclear fuel vehicle stats in for hopefully better mod compatibility, its fuel category is still different though
Version: 2.0.5
Date: 18.04.2026
  Major changes:
    - Removed some single use items (mixed oxide, depleted uranium hexafluoride)
    - Removed mixed oxide separation recipe, fission product extraction now directly produces plutonium and depleted uranium
    - Removed depleted uranium recipe, the enriched uranium hexafluoride recipe now directly produces depleted uranium as a byproduct
    - Fission product extraction has the sulfuric acid input replaced with light oil
    - Mixed oxide fuel rods no longer require depleted uranium

  Minor changes:
    - Another round of tech tree changes

Version: 2.0.3
Date: 17.04.2026
  Minor changes:
    - Added appropriate surface conditions to recipes that required fluorine/ammonia/lithium brine and couldn't be made elsewhere anyways
Version: 2.0.2
Date: 15.04.2026
  Minor changes:
    - Added nuclear waste to scrap recycling output, adjusted solid fuel output to keep total item probability the same
    - Lowered steam output temperature of acid neutralisation to 165C

    - Fusion power is unlocked with promethium science and has a new production chain

  Minor features:
    - Nuclear fuel values and some recipes have been changed
    - Productivity modules can be used on fuel rod recipes
    - Replaced lithium with uranium cores in the cryogenic science pack recipe
    - Added lithium to the centrifuge recipe
    - Nuclear weapon recipe changes
    - Solar panels in space have been weakened
    - Heat exchangers and steam turbines work with 515C steam
    - Add a direct space map connection between Nauvis and Aquilo
    - Fuel assemblies are too heavy for rockets
    - Changed stack sizes and rocket capacity values for most new items
    - Long recipe times have been lowered
    - Portable fission reactors use 6MW of fuel as buildings, up from 1.5MW
Version: 1.2.8
Date: 25.06.2025

Version: 1.2.7
Date: 16.02.2025
  Major features/bugfix:
    - Portable fission reactors no longer consume fuel in the equipment grid, due to there being no way to remotely insert fuel into the reactors of a vehicle
