I think that it's time for an update from the horse's mouth. Firstly, I'll be back from uni in about four weeks now to get back to working on the mod full time. As well as working on the new reactors for v2.10, I plan to revamp the textures (even perhaps models) and recipes of all machines, as right now, I think we can sort of agree that they're a little terrible
Now, the plans for steam production and use. The molten salt reactor will, on a basic level, take in fuel and produce depleted fuel and heat. That heat will then be transferred either to a salt coolant (those used in active coolers mixed with liquid NaK) to produce hot coolant, or directly to water to produce superheated steam.
If using coolant, the hot coolant is passed into heat exchangers (possibly multiblocks) with water - the heat from the coolant is passed to the water to produce superheated steam, which will be much more efficient than producing it directly.
The superheated steam then goes into a multiblock high-pressure steam turbine to produce energy and steam. The steam is then passed into a multiblock boiler (might just re-use the heat exchangers instead though) to produce reheated steam, which is then finally passed into a multiblock low-pressure steam turbine to produce energy and water.
I also have some plans I want to hold onto until the update to MC 1.13, as some changes would impact the game a little too much to allow for a smooth update to a new version of the mod. I am planning to add a little more realism to the current fission and fusion reactors:
Fission: First, I want to change the recipes and textures of some components, particularly the casing, ports, etc. to move away from lead to the more realistic iron/steel, and introducing more moderators which may or may not have particular pros and cons like the coolers. I am also pretty sure that I will remove the ability to actively cool the solid fuel reactors, as in some cases it can be a little too powerful and is often a way to bypass the puzzle of cooler placement. Thirdly, and probably most importantly, I want to, by default, move entirely away from direct energy generation and make steam production mandatory. There can be a config option to switch back to the classic energy generation for those that want it. For the solid fuel reactors, this will probably work pretty similarly to how Extreme Reactors produce steam, with the differences outlined above.
Fusion: The only current plan I have for the current fusion reactors is to move to steam generation instead of energy generation. Again, this would be configurable. The way it will work, roughly, will be that a 'heating blanket' is placed along the ring, which transfers heat to water or a coolant - note that, unlike the solid fuel fission reactor, the option of a non-water coolant will be an option for the fusion reactor.
Finally, what would you all think about an NC discord channel?
