Cooling a gigawatt-class reactor like that? - not a chance A 10kW reactor - easily; a very limited amount of engineering to design a heat distribution system will be required, but 10kW is also not enough for anything useful. I suppose the future of Moon energy will be in megawatt-class reactors, which are still possible to cool like that, but provide enough heat+energy to be useful for colonies.
