That's where the radiation would be.

But it's coming out.

Usually in most nuclear power plants, it also just comes right back out into the lake, river, ocean, just hotter than what it was in the beginning.

No, it's not touching anything that's radioactive.

So no.

But some power plants actually have cooling towers.

Not all of them do, but the cooling towers, they help recycle that water.

And so the water comes in from a large body, cools the reactor down, goes to the cooling tower, which then basically just like drops the water really from a really high point and it cools down that water.

And then that water goes back in and helps cool the reactor again.

Yes.

And then so the stuff that's coming out is like water vapor.

Yeah.

So that's, you know, a huge difference, obviously.

That's the vast majority of them.

There are a couple of different ones in the world, but that's the vast majority of nuclear reactors are what are called light water reactors.

And what that means is just that these types of reactors, they use water as both a moderator and a coolant.

And we can get into the details of that if you want, but...

That's fusion.

The easiest way to think about it is both are harnessing energy that was inside of atoms, which is really cool, right?

We can't even see atoms.
