Reactor Moderators (commonly incorrectly referred to as Reactor Coolants) are materials placed inside of a Reactor during construction. When a reactor is in operation, a moderator may change the way the reactor performs depending its properties.
The below information is accurate for Bigger Reactors 0.5.x (1.16) and 0.6.x (1.17-1.19) or earlier versions, the simulation changes in 0.7.x (1.20+)
Moderators have four main properties that affect the reactor simulation:
In general, higher values are always better (except for absorption, which may be better or worse depending on your reactor design). For a more in-depth explanation on how to use the information here, see the simulation page.
Something to note is that Modpack authors have the ability to add or modify moderators. For an accurate list of supported blocks/fluids, use Just Enough Items (JEI) by checking the uses for the Reactor Terminal (currently broken on multiplayer).
The values listed below are accurate for Bigger Reactors 0.5.2, for Minecraft 1.16.5. Also correct for 0.6.x (1.17-1.19)
