Liquid Thorium Salt
Liquid thorium salt is the strongest flux multiplier for the PWR, which is also unique compared to other PWR coolants.

Production
Liquid thorium salt is produced in the industrial mixer:
1,000mB
1,000mB
it is an expensive coolant, requiring a lot of chlorine and thorium to fill a PWR. Production can be helped with bedrock ores.
Usage and Cooling
It is only used as a PWR coolant. It is the strongest flux multiplier, adding a whopping +150% to the core flux.
Besides it being a strong flux multiplier, it is also special compared to other coolants. When the hot liquid thorium salt from the PWR passes through a heat exchanger, it turns into depleted liquid thorium salt, which can't be used in the PWR. However, the depleted thorium salt can be enriched in a chemical plant:
16,000mB
16,000mB
Liquid thorium salt also has a 400 TU heat capacity per mB of it.

Pros and Cons
Because of it being a strong flux multiplier, it can be used in setups designed for breeding fuel.
Liquid thorium salt can also turn the PWR into a Uranium-233 megafactory. While only one nugget per 16000 mB of thorium salt seems like a small amount at first glance, the PWR can heat up the coolant very fast, producing a lot of U-233 and generic nuclear waste as a byproduct.
However, because the PWR heats up so much coolant at once, it can be too much even for the 3-second process of enriching the thorium salt, so speed upgrades or several chemical plants may be required in order to keep up with the output.
The fact that it is a strong flux multiplier doesn't come without its burden: The flux increase can be too much to handle for the PWR and melt down, especially those that use strong fuel rods, such as HES-326.
