Heavy Water

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

In Nuclear Tech Mod, Heavy Water is a fluid used as coolant in the Pressurized Water Reactor (PWR)

Heavy Water is a bright-blue fluid that only purpose, as stated, is to act as coolant in the PWR. Extracted from Water, it uses 2 machines in the mod for the exchange of fluids in order 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 Anvil of Tier 2 (Steel) or above, and can store 100mB of the fluid:

The Deuterium Extraction Tower is a multi-block machine that also uses power, 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:

Heavy Water can be electrolyzed both in the Chemical Plant and in the Electrolysis Machine:

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.
