Heavy Water

Not to be confused with Deuterium, as they are both different things, in real life and in-game.

Heavy Water (${\ce {D2O}}$) is a liquid PWR coolant and flux multiplier extracted from water, using 2 machines for the exchange of fluids for the acquisition of the fluid.

Production

• Heavy Water is extracted from 2 machines: The Deuterium Extractor and the Deuterium Extraction Tower:
• The Deuterium Extractor is a single-block machine, uses power, and turns water into heavy water in a 10:1 ratio. It can be made in a tier 2 anvil (steel) or above, and can store 100mB of the fluid:

• The Deuterium Extraction Tower is a multi-block machine that also uses power, but turns water into heavy water at a faster rate, and also stores more of the fluid in it, about 5000mB. It can also be made in a anvil but from Tier 4 (Ferrouranium) and above, however it also needs sour gas, which places it post bismuth:

• The Deuterium Filter is a item used to craft the Deuterium Extraction Tower, requiring 2 of them for the tower:

• As stated earlier, the main use of heavy water is as a PWR coolant, it has a thermal capacity of 300 TU per 1mB, same as regular coolant
  • However, unlike regular coolant, heavy water is also a flux multiplier adding +25% to the core flux, increasing the reactor's efficiency.

• Despite the hot variant being under the melting point of the RBMK columns, it is not compatible with the RBMK because it would behave the same as regular coolant, and the flux multiplication feature doesn't work in the RBMK.
