No space material used, steal is the most advanced, built in creative.
I avoided using steam turbines in an attempt to maintain realism, the older turbines would've been a lot more realistic for this build. The aqua tuners are acting as heat pumps to cool and concentrate the reactor's thermal output, allowing water to be used as the coolant without fluid pressure dynamics being modeled. The steam block is standing in for a turbine/salt water boiler. There is nothing about this reactor which could not be replicated in the real world.
