With regard to the safety of NaK alloy, it is obvious that this will not happen in GT6. And you have added molten sodium coolant, so there will be no problem with potassium with similar natural properties. I think this can make potassium more useful. Its performance should be better than molten sodium.
For molten metal reactors, in addition to NaK, another commonly used coolant is eutectic molten lead-bismuth alloy, which has poor performance, low heat capacity and will absorb a lot of neutrons. The main reason for using in reality is that it will not cause danger like NaK, nor will it produce serious corrosion.
For the molten salt reactor, in addition to the lithium chloride currently available (it’s strange that I didn’t find lithium chloride as reactor coolant in reality, although it seems feasible in theory), it also includes FLiNaK and FLiBe. These two mixed salts will have higher heat capacity and performance, However, they are also difficult to obtain (they are added to the branch of GTCE Gregicality and can be used in their reactors).
In addition, for water-based reactors, there is another coolant option: boric acid solution coolant. It will have higher heat capacity and moderation. At the same time, it will absorb more neutrons, which is conducive to stabilizing the reactor. In reality, many are used. This may make the borax vein more useful, or add a boron neutron absorber like HBM.
As for breeding, in addition to the balance of neutron exponential growth, I also hope to use lithium to breed into tritium, so you don’t need to spend too much time on centrifugal water to obtain tritium. Adding more logistics machines will make it easier to automate the breeder reactor.I very much hope that adding logistics machines like Regulator can make the automation of reactors easier.
