Thanks for pointing this small but very significant oversight out, I just fixed it.
As a small side update, the code for everything I want to add is done and pushed. That means that molten salt and thorium salt are added as reactor coolants. A new reactor coolant focusing on making absorber rods more useful hasn’t been added, but the existing ones have been rebalanced or changed completely, to make each one more useful and unique.
The industrial coolant one is ofc left unchanged, still filling the role for subcritical reactors and being a good use case for absorbers.
Water has also been left largely unchanged mechanically, old reactor designs still work, but there has been a significant minor change: Water now causes fuel rods to become moderated. This makes water reactors inherently more inefficient, as moderated fuel rods have double the durability consumption and can’t be used for breeding. Using moderator rods in water reactors is also encouraged this way, as they don’t provide any additional debuffs, as their debuff is already applied.
Liquid metal reactors have been left unchanged, still fulfilling their role as breeder reactors.
Gas reactors are probably changed the most and now fill the role of the basic unmoderated supercritical reactors and breeders. They no longer decrease the neutron maximum and are much more stable because the neutron emission has been decreased. Helium and CO2 are also much more distinct and not just linear upgrades. CO2 raises the factor slightly while Helium decreases it. This allows Helium to operate only very high factor fuels supercritically (factor >= 1/3) without moderation, but do so much more stable, CO2, although being more unstable, can be used as a supercritical breeder even with fuels with a factor of 1/4 or as a very compact supercritical reactor.
Molten salt (LiCl) is one of the best coolants available, having a emission as low as Helium, but not increasing or decreasing the factor. The biggest benefit still being, that the neutron maximum of fuel rods is raised by 50%.
Thorium salt is in a way the coolant that makes absorbers really useful. It increases the neutron maximum by a factor of 4! But this massive increase comes at a price, the coolant, the thorium salt, isn’t turned into usable heatant by neutrons, but just cold molten salt used to produce the thorium salt. The energy needs to be extracted by a secondary reactor loop with another coolant. To help a bit, it increases the factor a bit like CO2, while still halving he emission. The self emission is also set to 0.
I’ll probably do a full documentation soon-ish
