Nuclear Salt Processing Plant

The Nuclear Salt Processing Plant (NSPP) is an IV tier multiblock for condensing volatile uranium hexafluorides and for recycling depleted/sparged salts. The NSPP is a direct upgrade from the singleblock reactor processing unit and cold trap because it runs at 250% speed and offers 2 parallels per voltage tier. The structure is effectively two halves with inputs on the left and outputs on the right. Depleted Salts come directly from the Liquid Fluoride Thorium Reactor and sparged salts come from the Sparge Tower. The latter yields twice as much output for the same amount of salt which makes it a worthwhile intermediary step.

The NSPP has no tiered components and several restrictions on its buses/hatches. Inputs are limited to the insulated casings on the left side of the structure and outputs are limited to the insulated casings on the right side of the structure. There must be exactly two muffler hatches on the top of the structure and two energy hatches on the bottom of the structure. They do not have to be identical or even the same voltage tier, although it always defaults to the lowest of the two. Multi-amp and laser energy hatches are not supported. The maintenance hatch is limited to the one casing directly behind the controller. Use the Multiblock Structure Hologram Projector to visualize/build the structure.

Structure

• Controller: Front center, 3rd layer
• 58 IV Machine Casing
• 0-32 Thermally Insulated Casing
• 2 Energy Hatch: Bottom insulated casings
• 1 Maintenance Hatch: Casing behind controller
• 2 Muffler Hatch: Top insulated casings
• 0+ Input Bus: Any left side insulated casing
• 0+ Input Hatch: Any left side insulated casing
• 0+ Output Bus: Any right side insulated casing
• 0+ Output Hatch: Any right side insulated casing

Wallsharing

NSPPs may wallshare each of their sides to save on casings and buses/hatches. That includes the muffler hatches since the interior of the structure is hollow, but not the energy hatches because there are always two of them.

The NSPP is a direct upgrade from the singleblock reactor processing unit and cold trap because it runs at 250% speed and offers 2 parallels per voltage tier, as seen in the following table. Chance outputs are rolled independently between parallels.

There are only six reactor processing unit recipes, listed below with their programmed circuit value in brackets and chance outputs in parentheses. Three are for the depleted salts and three are for their sparged equivalents. The latter yields twice as much output for the same amount of salt which makes it a worthwhile intermediary step. It is highly recommended to send the P-UF6 and F-UF6 to another NFPP instead of rerouting back into the same machine to avoid a massive bottleneck in the fuel recycling process. The Impure molten salt base, lithium fluoride, and beryllium fluoride are all used to make more fuel for the Liquid Fluoride Thorium Reactor. The only use for the protactinium dust is making rods for the Bacterial Vat's radio hatch.

There are only two cold trap recipes, listed below with their programmed circuit value in brackets and chance outputs in parentheses. Note that P-UF6 is obtained from U-Salt and F-UF6 is obtained from T-Salt or TB-Salt. The uranium hexafluoride and the uranium-233 are both used to make more fuel for the Liquid Fluoride Thorium Reactor. There is no other use for the molten sodium fluoride so that can be rerouted back into the input side of the NSPP.
