Modern AI data centers consume enormous amounts of power, and it looks like they will get even more power-hungry in the coming years as companies like Google, Microsoft, Meta, and OpenAI strive towards artificial general intelligence (AGI). Oracle has already outlined plans to use nuclear power plants for its 1-gigawatt datacenters. It looks like Microsoft plans to do the same as it just inked a deal to restart a nuclear power plant to feed its data centers, reports Bloomberg.

I think I saw a movie like this.

It doesn't end well. πŸ’€

[–] [email protected] 22 points 7 hours ago (1 children)

Personally? I don't think this is a bad idea. The less they drain from the grid, the less they consume fossil fuel.

The reactor isn't active right now, and they are a PWR design, and like the 1979 incident showed, they do fail safely.

So long as Microsoft pays for the operation of the plant? Seems reasonable to me if they're going to consume an assload of energy with or without public support.

[–] [email protected] 17 points 7 hours ago (2 children)

we could use that extra energy to offset a bunch of existing carbon emissions now. This is still waste. If it's going to be started up again, and its energy used for something useless, it's waste.

[–] [email protected] 2 points 6 hours ago (1 children)

Is it going to be started up again?

If M$ doesn’t invest into this for their own purposes, is it still going to be started up? Or is your position that M$ should be investing in a nuclear power plant for the good of the world?

Because while I can agree with the idea, we all know that would never happen. So if it was never going to be started up again, we are at 0 gain or loss no matter what they do with it.

And that’s ignoring the fact that they are apparently intending on using that energy anyway.

[–] [email protected] 1 points 5 hours ago* (last edited 5 hours ago)

it would be a missed opportunity in the sense of "if they can allow it to be turned it back on to waste its power on this dead-end tech, why couldn't it have been allowed to operate again (earlier) for reasons we actually need?"

I'm not putting the blame on microsoft here, even though it might seem that way. But it's not microsoft who need to give the go-ahead for this to happen. It's the higher ups who decided to give the capacity to microsoft.

Yes it was still going to be used, but they could have been paying out the ass for it, which could fund other projects.

[–] [email protected] 12 points 7 hours ago

Microsoft would do it with or without the power plant. Make no mistake about that.

The same argument could be said if they made a 1GW solar farm, or any other form of power generation. Unless you have a way to legislatively prevent Microsoft from producing their own energy or prevent acquisition of decommissioned plants, I don't see how you can prevent waste.

[–] [email protected] 17 points 8 hours ago (1 children)

I just hope this deal doesn’t involve using their AI to monitor the reactor …

[–] [email protected] 7 points 8 hours ago (2 children)

There actually has been good work on using AI to control fusion plasmas its at the point where it can keep them stable significantly better than any human or simple automated system.

[–] [email protected] 6 points 7 hours ago

Yes in a research lab. Here we’re talking about Microsoft.

Have you ever used something they made? Did it meet your standard of being β€œgood work”? No. It’s a greedy, soulless cash grab disguised as software that infects the entire organization and disables common sense.

M$ actually running a nuclear plant is a guaranteed disaster. Blue Screen of Death.

[–] [email protected] 7 points 8 hours ago (1 children)

You know, that actually makes sense. Fusion is so energetic and probabilistic in nature, plus it's effectively "charged fluid dynamics" and there are an impossible number of variables to handle. That's literally the kind of shit AI is great at.

Fission though? Not so much

[–] [email protected] 6 points 8 hours ago (1 children)

No, stick rod in / pull rod out doesn't really need deep learning to make work well :p

[–] [email protected] 10 points 7 hours ago

Apparently, I didn't learn that with my ex

[–] [email protected] 25 points 9 hours ago

Ironically, the power hungriness of AI might actually do good for the environment if it normalizes nuclear energy.

Quite the twist

[–] [email protected] 8 points 9 hours ago

Based on their Windows updates history, this seems like a bad idea. Nuclear boogaloo let's goooooo

[–] [email protected] 11 points 11 hours ago (1 children)

I am all for nuclear power, but I'd rather it be from modern reactor designs and builds, and I'd rather it not be wasted on bullshit.

[–] [email protected] 5 points 8 hours ago

Hey now that's not fair. AI can randomize your music playlists, summarize an email, write terrible code, steal others work, and completely invade your privacy.

What's that? Oh, I guess you're right, we could do all that stuff already.

[–] [email protected] 21 points 12 hours ago (1 children)

This sounds like the intro to a bad post-apocalypse sci-fi movie.

[–] [email protected] 1 points 8 hours ago (1 children)

I think pre post-apocalypse is just the apocalypse. If you read the news these days that sounds like a pretty accurate description of the time we're living in. We're all just pretending it hasn't started yet.

[–] [email protected] 4 points 7 hours ago

Turns out planetary extinction without an asteroid is slow AF.

[–] [email protected] 30 points 12 hours ago (3 children)

Holy sunk cost fallacy, batman. How fucking much does it cost to operate an ENTIRE GODDAMN NUCLEAR REACTOR just to fuel a tech project that nobody wants???

[–] [email protected] 3 points 6 hours ago

A lot of the cost is building a giant centralized nuclear facility. Once they are built it is not nearly as expensive to run them.

I think this is generally a good thing. Companies should be thinking of ways to supply their power needs.

Having said that, people want a good AI. The LLMs they are working on are probably not that. I am very skeptical we are anywhere close to where the hype train has taken us

[–] [email protected] 13 points 12 hours ago

that nobody wants

lol

[–] [email protected] 24 points 12 hours ago (1 children)

Investors want it, because they want to ride the wave towards profit. It doesn't matter if it's good, sustainable or not. That is what matters.

[–] [email protected] 1 points 6 hours ago

A tax break for "clean energy", "strategic investment corridor" or "self-poweting companies" to reduce the load on the grid (that a few enormous companies like MS are creating) will be written into law, if it isn't already, and it will be a complete tax write-off or something so they get to reap any rewards and when AI hype dies down they'll still have increased profits by reducing taxes. When you win/win by owning the system you just win.

[–] [email protected] 91 points 12 hours ago (5 children)

Lol. I just love it how so many people complain that Nuclear doesnt make financial sense, and then the most financially motivated companies just actually figure out that using a nuclear reactor completely privately is best.

Fuck sake, world.

[–] [email protected] 11 points 7 hours ago (1 children)

Nuclear safety and penny-pinchers don't make good bedfellows.

[–] [email protected] 5 points 7 hours ago (1 children)

Nuclear safety and ~~penny-pinchers~~ capitalism don't make good bedfellows.

ftfy. Possibly ironically, nuclear safety and communism (or totalitarianism) don’t work either. It’s odd, innit.

[–] [email protected] 3 points 6 hours ago (1 children)

Pretty sure it has to do with how the plant is designed and operated as opposed to what economic or governmental system it happens to exist under.

[–] [email protected] 1 points 6 hours ago (1 children)

Doesn't that design and operation get created by the economic or governmental system it's under?

[–] [email protected] 2 points 6 hours ago* (last edited 6 hours ago)

I think with the USSR at least, that their reactor designs were supposed to be less safe than western reactor designs.

Was it because they were a shitty oligarchy claiming to be communist? Maybe, they did make a lot of garbage decisions.

I think the US has the record for most nuclear disasters by a lot but two of the worst were in the USSR.

[–] [email protected] 6 points 10 hours ago (1 children)

I'm firmly in the "building new nuclear doesn't make financial sense" camp, but I do think that extending the life of any existing nuclear plant does. Restarting a previously operational nuclear plant lies somewhere in between.

[–] [email protected] 6 points 7 hours ago (1 children)

I think when you start looking at how expensive other forms of green energy are (like wind) long term, nuclear looks really good. Short term, yeah it’s expensive, but we need long term solutions.

[–] [email protected] 1 points 3 hours ago (1 children)

I don't think that math works out, even when looking over the entire 70+ year life cycle of a nuclear reactor. When it costs $35 billion to build two 1MW reactors, even if it will last 70 years, the construction cost being amortized over every year or every megawatt hour generated is still really expensive, especially when accounting for interest.

And it bakes in that huge cost irreversibly up front, so any future improvements will only make the existing plant less competitive. Wind and solar and geothermal and maybe even fusion will get cheaper over time, but a nuclear plant with most of its costs up front can't. 70 years is a long time to commit to something.

[–] [email protected] 2 points 2 hours ago

Can you explain how wind and solar get cheaper over time? Especially wind, those blades have to be replaced fairly often and they are expensive.

[–] [email protected] 25 points 10 hours ago* (last edited 10 hours ago) (2 children)

Microsoft jumped fully on the AI hype bandwagon with their partnership in OpenAI and their strategy of forcing GenAI down our throats. Instead of realizing that GenAI is not much more than a novel parlor trick that can't really solve problems, they are now fully committing.

Microsoft invested $1 billion in OpenAI, and reactivating 3 Mile Island is estimated at $1.6 billion. And any return on these investments are not guaranteed. Generally, GenAI is failing to live up to its promises and there is hardly any GenAI use case that actually makes money.

This actually has the potential of greatly damaging Microsoft, so I wouldn't say all their decisions are financially rational and sound.

[–] [email protected] 11 points 9 hours ago (1 children)

On the other hand, if they ever admit the whole genAI thing doesn't work, they could just sell the electricity produced by the plant.

[–] [email protected] 3 points 7 hours ago

if they ever admit the whole genAI thing doesn't work

. . . The entire multi-billion-dollar hype train goes off the cliff. All the executives that backed it look like clowns, the layoffs come back to bite them - hard - and Microsoft wont recover for a decade.

I mean . . . a boy can dream

[–] [email protected] 5 points 10 hours ago (4 children)

Have they solved the disposal questions?

[–] [email protected] 5 points 8 hours ago

Relatively yes. There are disposal sites under construction that are in highly stable and environmentally safe locations. One good thing right now is that radioactive waste is temporarily easily stored. Transport of waste is an issue still, but far less of a problem than transporting oil and oil products.

[–] [email protected] 8 points 9 hours ago

Mostly, yes. Use breeder reactors to turn long term radioactive waste to sort term radioactive waste, store for short time and done. The downside: it's more expensive to move and process the stuff so nobody wants to do that.

[–] [email protected] 17 points 10 hours ago

We haven't solved the "disposal" question of using fossil fuels, and those turned out (or were known along) to cause much bigger problems.

[–] [email protected] 7 points 10 hours ago

Like most things with environmental impact, we just let later generations deal with it. Somehow.

[–] [email protected] 22 points 12 hours ago (1 children)

Honestly it seems crazy that companies that are so focused on short-term profits in 2024 would be able to make nuclear work.

[–] [email protected] 9 points 8 hours ago

Every once in a while they get faced with a line on a chart somewhere so unbelievably vertical that they have no choice but to look beyond next quarter. Power consumption going 10x in 2 years is one of those times.
