Reactor Fuel Processing Plant

The Reactor Fuel Processing Plant (RFPP) is an IV tier multiblock for refining fluorides and uranium into nuclear fuel for the Liquid Fluoride Thorium Reactor (LFTR). There are only three fuels in total, but there are alternate recipes for LFTR fuel 2 and 3 that are much more direct/efficient. Regardless, the recipes are all very long and only one energy hatch is allowed per RFPP. Expect to have more LFTRs than RFPPs, especially if using higher tier energy hatches.

The RFPP consists of four different types of casings. Buses/hatches may only replace the Hastelloy-X structural blocks on the bottom of the structure. Multi-amp and laser energy hatches are not supported and there can only be one regular energy hatch. The muffler hatch must also be IV+. Use the Multiblock Structure Hologram Projector to visualize/build the structure.

Structure

• Controller: Front bottom center
• 17 Hastelloy-N Sealant Block
• 7-11 Hastelloy-X Structural Block
• 5 Incoloy-DS Fluid Containment Block
• 4 Reactor Shield Casing
• 1 Energy Hatch: Any hastelloy-X casing
• 1 Maintenance Hatch: Any hastelloy-X casing
• 1 Muffler Hatch: Any hastelloy-X casing
• 2+ Input Hatch: Any hastelloy-X casing
• 1+ Output Hatch: Any hastelloy-X casing

Wallsharing

RFPPs may wallshare each of their sides to save on casings and buses/hatches. No recipe uses more than 1A of power so it is possible to share one energy hatch between two machines.

There is nothing particularly unique or challenging about using the RFPP. The few recipes that do exist are all very long and require 2-4 fluid ingredients. Try using a quadruple input hatch or ME stocking input hatch to stay above the minimum casing requirement and simplify setups. The following table lists the number of LFTRs that are supported from a single RFPP running each recipe at different voltages.
