Big radiators?
Filled with water from where?
Isn’t there water in the lunar regolith?
Earth, I assume. Could also be solid metal or filled with liquid sodium or something if it needs to circulate.
Sounds pretty costly to bring all that up
But yeah, solid metal as heat transfer could work. Still how to drive a turbine?
Could you skip the turbine and slap a bunch of peltier elements on the reactor?
Probably not super efficient, what with the vacuum of space being bad at absorbing hear, and if I recall right peltier produces more power the larger heat gradient.
There are a lot of seas on the Moon after all.
