One of the biggest (currently) late game challenges in Satisfactory is storing the nuclear waste generated by your reactors, requiring large areas of the map to be quarantined due to radiation. But what if I were to recommend a real life solution, that has been used since the 1960's, which can use most types of radioactive material as fuel? This type of reactor is called a 'Fast Neutron Reactor', and can "burn up" nuclear wastes, releasing more energy than most normal reactors per uranium / plutonium used.
To unlock this magnificent machine, I was thinking about having to research a new recipe, called "Reactor Blanket" (will explain later), which unlocks a new product in the manufacturer requiring:
25 nuclear waste + 3 heavy modular frames + ~50 concrete
60 second construction time
stacks to 200
(should be able use the waste from 5 reactors without causing surplus).
As well as providing a new blueprint in the power tab, called the 'Burner Reactor', requiring:
15 heavy modular frames + 5 supercomputers + 5 turbo motors + 60 alclad aluminum sheets + 15 high speed connectors.
The new reactor will have 2 inputs and no output, and will require:
1 nuclear fuel rod + 4 reactor blankets = 3200-3800MW (not sure yet)
IRL, these 'reactor blankets' would be composed of nuclear wastes and/or non-fissile isotopes like U238, placed around a central 'core' of more fissile material like U235 or Pu239, either to burn them (like this proposal) for more energy, or fission them into other materials like Plutonium (the vast majority of Pu is synthetically made like this, though small amounts can be found within natural uranium). However, this kind of reactor requires highly enriched uranium or plutonium, enough to make a practical nuclear weapon, which is a security risk, as well as being expensive to refine the uranium and plutonium to levels that make the reactor run efficiently. I don't know the enrichment level of the satisfactory nuclear fuel rod, but for this proposal, to reduce complexity, I will assume it's high enough to be used in the burner.
With such a building (5 reactors feeding 1 burner), not only will you get rid of your nuclear waste, but you will increase your power supply by 25-30%! There is still a radiation hazard around the site(s) these buildings are located, but no longer will you have to suffer with massive reactor waste depots that will, given enough time, fill up if using lots of nuclear power. I believe the resources required to build this reactor, as well as the extra machines and space, will help balance out the fact that you no longer have to worry about waste storage, and will make nuclear energy in game a more attractive option to (over)produce!
What do you think of my suggestion? Is there anything I missed or you would like me to elaborate on? Leave a comment, and upvote if you think this will help clear up all the nuclear waste you're accumulating!
