The lunar exosphere is too skimpy to trap or spread the Sun’s energy, so differences between sunlit and shadowed areas on the Moon are extreme. Temperatures near the Moon’s equator can spike to 250°F (121°C) in daylight, then plummet after nightfall to -208°F (-133°C).
The big problem with space is overheating. Space may be cold but there is no way to get rid of that heat except for radiators. Convection doesn’t exist in a vacuum.
It’s already pretty cold
Only at night.

Which sounds like a pretty big challenge for a nuclear reactor. Maybe they only plan to put them on the poles?
