How a Closed Nuclear Loop with Ficsonium Works and How to Build It

What this layout shows

Watch the Plutonium Waste pass through Ficsonium into fuel rods, with all three kinds of fuel rod entering the plants.

How it works

Make Uranium Fuel Rod as in stage 1 and Plutonium Fuel Rod as in stage 2, and burn each in Nuclear Power Plants.
Feed the Plutonium Waste into a Particle Accelerator with Singularity Cell and Dark Matter Residue to make Ficsonium.
Dark Matter Residue comes from Reanimated SAM in a Converter. Singularity Cell is built in a Manufacturer from Nuclear Pasta, Dark Matter Crystal, Iron Plate and Concrete.
Feed Ficsonium, Electromagnetic Control Rod, Ficsite Trigon and Excited Photonic Matter into a Quantum Encoder to make Ficsonium Fuel Rod. The Dark Matter Residue it gives back goes into the Ficsonium step.
Burn the Ficsonium Fuel Rod in a Nuclear Power Plant. This rod leaves no waste, so no nuclear waste ever leaves the site.

Results compared with “Nuclear, stage 1: uranium power”

These are not fixed illustrative figures: they are solved again on game data 1.1.x every time the static pages are generated.

The baseline is “Nuclear, stage 1: uranium power” solved again with the same target. Read the change in raw resources together with the generator count, the waste left over and the production power.

Metric	Baseline → template	Change
Water	504.00 → 522.27 m³/min	3.6% more
Iron Ore	87.90 → 94.80 items/min	7.8% more
Copper Ore	62.00 → 177.95 items/min	187.0% more
Limestone	57.60 → 92.91 items/min	61.3% more
Uranium	40.00 → 22.86 items/min	42.9% less
Coal	27.90 → 66.79 items/min	139.4% more
SAM	16.00 → 75.65 items/min	372.8% more
Raw Quartz	0.00 → 17.70 items/min	Newly used
Nitrogen Gas	0.00 → 15.14 m³/min	Newly used
Crude Oil	0.00 → 5.49 m³/min	Newly used
Generators to build	2 → 4	100.0% more
Uranium Waste left over	20.00 → 0.00 items/min	None left
Heavy Oil Residue left over	0.00 → 1.83 m³/min	Newly produced
Production power	231.43 → 488.20 MW	111.0% more

Power covers the production buildings and the fuel chain; extraction machines are not included.

Notes for building it in game

The plan reprocesses all of the Uranium Waste and all of the Plutonium Waste. A stall anywhere backs the waste up into the plants and stops the power, so put containers in front of each waste step as a buffer.
The radioactive materials now include three kinds of fuel rod and two kinds of waste. Keep the reprocessing block away from the factory proper, and protect yourself with walls, distance and Iodine-Infused Filters.
On top of Sulfuric Acid and Nitric Acid you need pipes for Excited Photonic Matter and Dark Matter Residue. Run the fluids and gases in before starting and confirm that the Particle Accelerators and the Quantum Encoder can accept them.
Only two settings differ from stage 2: Ficsonium Fuel Rod was added to the fuels, and “leave none behind” is ticked for Plutonium Waste. To stop at plutonium, undo those two.
