Re: Fit in faring
According to the Starship user guide you can have 8m tall with 8m diameter + another 9m tall tapering to 3.6m diameter. Mass limit is at least 100,000kg. We do not have final specs on HLS Starship and that may have stretched tanks and landing engines that cut into the payload space and mass. 4x 10kW of fission power comes to a piffling 6,000kg.
If you are only landing and not returning a Starship would not need the stretched tanks and you avoid the difficulty of unloading your nuclear reactor from inside a fairing 30m above the surface of the moon. The bad news is you then have to get about 170kW of heat out of the fairing. About 8,000kg of radiator would be sufficient but you could cut that down considerably by using the Starship as a radiator and a big fan inside the tanks to spread the heat with the ullage gas.
