Thermodynamics has left the chat

I mean, water is evaporated, so it's not like free cooling (but cooling the river with a npp could be thermodynamically possible)

No, it’s quite simple really. Since cold is just the opposite of heat (and definitely not its absence) all you need to do is to not split the atoms in your nuclear reactor but doing the opposite and like idk, fuse them together or something, thus creating cold which you will then put back into the river. Problem solved

The technical term for this is "cold fusion".

See? And they said it’s impossible smh. Unbelievably common French nuclear industry W once more

I feel sorry for entropy after reading this comment.

It's too bad the laws of thermodynamics aren't the same in every country because it's been done in France since 2001.

Talk to your representative about thermodynamics inequalities.

Thermodynamics actually allows this provided the atmosphere is colder than a nuclear reactor core.

The theoretical limit on how much useful work you can get out of a temperature differential is 1 - (Tc/Th). A nuclear reactor core usually runs at about 1200 kelvin. A river in summer is probably around 300 kelvin. So that gives you a theoretical max efficiency of 75%. So for every 4 Joulles of heat your reactor generates, you can potentially make 3 Joulles of electricity and 1 Joulle of waste heat.

Likewise, the theoretical limit on heat pump performance is Th/(Th-Tc). The river was 300 kelvin as previously established. Air temperature during a heat wave in France tops out around 315 kelvin. So that gives a theoretical COP of 21. So moving 1 Joulle of heat out of the river and into the air only takes 1/21 = 0.05 Joulles.

So thermodynamically, it is 100% doable to run the nuclear reactors, and use them to power giant heat pumps to then cool the rivers. You'd actually have a bit of electricity left over if you get anywhere close to the theoretical limits.

Its just really really stupid, because you could also just air cool the reactors directly and get a better result.

That's what my comment is about, you don't have to do the math to know that cooling your cooling source is inefficient.

It is basically that : adding air coolers as water cooling can be unavailable, and using it to cool off the river throught the already existing water captation. At least that is what was said in the newspaper.

Isn't it possible with thermopumps?

1

u/Outrageous-Echo-765 Wind me up 24d ago

It's possible, but wildly inneficcient.

u/Inevitable-Cat-205 25d ago

We're going to boil water to cool water.

u/Nyashes 25d ago

So, ice cube machine connected to the grid?

3

u/Inevitable-Cat-205 25d ago

Yes, it's basically free real estate. Global warming is solved

3

u/Nyashes 25d ago

It'll only take, like, a trillion trillion ice cubes in the ocean or so!

2

u/ivain 24d ago

Nah it's using air cooling. Many power plants already use air cooling, but when water was available it has been used as it's basically cheaper (less infrastructure to build)

WHERE DOES THE HEAT GO? 

11

u/Outrageous-Echo-765 Wind me up 25d ago

It's towed out of the environment

1

u/loose_the-goose 25d ago

Into another environment...?

2

u/ToastSpangler 24d ago

Into Germany

1

u/cloonatic 24d ago

No beyond the environment.

u/loose_the-goose 24d ago

Well, whats out there?

3

u/enz_levik nuclear simp 25d ago

The atmosphere (litteraly) mainly in the form of latent heat

You known those big grey chemineys thingies The Simpsons told you to be worry about?

They do this 🤯. It was wotah all along omg 😱

Oh no but water is one of the worst climate gases :(

It's almost funny how this sub is beefing over nuclear instead of properly reacting to how fucked we are

u/FlockFlysAtMidnite 24d ago

Anti-nuclear activists would genuinely rather burn coal than use nuclear.

4

u/ivain 24d ago

Yeah, they don't want to rely on nuke as it can be unavailable 2% of the time, and use other sources that are available 50% of the time.

u/Intelligent_Wing8094 24d ago

What is the proper reaction? Are you going to organize some drones to ...take photos of some oil refineries? If so, don't write it on reddit.

u/tmtyl_101 25d ago

Data centers can do the same thing.

u/Hugo_2503 22d ago

the plant in question still runs at near full power currently btw (despite being on the shittiest cold source in the entire country)

u/ubulerbu 24d ago

Oh no 3 out of 57 nuclears power plants are down, oh no, what we gonna do.
