Nuclear power requires active cooling. All heat engines do. You need a hot side and a cool side.
Good thing space is really fucking 🥶 That said maintenance, building etc everything would be a huge bitch and prohibitively expensive
Space isn’t cold. Vacuum doesn’t have a temperature. Removing heat from an object in space is slow. If your body could withstand the vacuum, space would probably be a very comfortable place unless you got wet.

It's all dependent on solar radiation. In the sunlight its actually hot as fuck, in the shade its colder than ice.

The shade isn’t cold. Vacuum doesn’t have a temperature. A warm object would cool much slower in the shady parts of space. A human body would lose heat energy much slower in space than on earth where much of that energy is convected.
A warm object in space will cool more slowly but it will eventually radiate almost all its heat into space. In an atmosphere the cooling would stop when it reaches ambient temperature

Wasn't the discussion about cooling off a nuclear reactor in space?
If an object in space like the moon, when it is not exposed to direct sunlight is approx -250F wouldn't that suggest that the vacuum of space is actually 'cold'?

Apparently it would take 12-24 hours to freeze solid in space if you were to step out into it.
"It's also very cold in space. You'll eventually freeze solid. Depending on where you are in space, this will take 12-26 hours, but if you're close to a star, you'll be burnt to a crisp instead.May 13, 2021"
So if something had a bunch of cooling fins I would expect it to cool quite well I suppose.

I imagine a space nuclear reactor would involve some form of rotation to keep it from getting too hot or cold.
All that said, I would think that it would be wiser to install massive solar installations for the purpose of bringing power to earth. The nuclear reactors will likely be used for spaceships and shit like that. That's my guess.

The nuclear reactor is going to beam the energy back to Earth through the Big Macs secret ingredient HARRP.

You're joking, but a solar array in space could probably be used as a weapon. I bet they could start a forest fire easy with that shit.

I think they are trying to play semantics/technicalities. If I remember correctly from my astronomy classes space itself isn't 'cold' but it does make things cold. I forget the exact reasoning behind it. That said, if an object isn't being heated up by the sun it freezes, so if you ask me, it's fkn cold.

But the object were talking about is a nuclear reactor which is producing its own heat. How are you going to cool that in the vacuum of space?

Doesn't a human body produce it's own heat? Would it not freeze in space (if it was in the shade). Same with Earth. The night side is colder than the day side.
"The temperature on the side of the International Space Station (ISS) facing the Sun can reach 121 °C. The side facing away from the Sun can go as low as -157 °C. This is a difference of almost 300°C!"
So, I imagine that the shaded side of the nuclear reactor would experience cooling of -157C (or something like that). That said, when I looked it up a nuke reactor reaches something like 300C; which would mean that when not exposed to the sunlight it should only reach ~150C. I'm not sure what the operating temp is tho, or how cold/hot they have to keep it from melting down or breaking. I'll have to look into that.
Regardless, like I said, nuke reactors in space will likely be reserved for space ships. Who, as they get further from Earth and thus the sun, the colder they will get. As a result it may actually become necessary to insulate the reactor while rotating it to keep it from freezing while also preventing it from overheating.
Giant solar arrays will likely be used for power collection if I had to guess. As some of us have already suggested.

A human body in space produces no heat.
Is that because it's dead? Surely there would be a period of decomposition that would generate some heat and residual cellular activity
