The temp is low but it is a vacuum. Vacuums are bad at dissipating heat. Think of the vacuum walled drinking vessels. They are so efficient at keeping beverages hot/cool because the vacuum insulates the majority of the surface area that heat can move across.
Likewise a cooling tank of water (typical nuclear reactor design) itself surrounded by vacuum, will not cool efficiently at all. Presumably they’d have to use piping to circulate the water over a large surface area of some other medium like the moon rock itself.
The IR band gap is high enough that you’d need really efficient heat pumps to keep things radiating well. Otherwise the heat pumps generate more heat than you can radiate.
I’ve got it. Since we’re worried about rising sea levels on earth, we can just pipe the excess water to the moon and flood the moon’s surface with water and use that for cooling.

They’re also very good at not stopping infrared radiation.
