they will be dependent on their allies for fuel sources.. in a list of countries with uranium resverves 1-59 they're number 55! https://en.wikipedia.org/wiki/List_of_countries_by_uranium_r...

Did you honestly not look at the numbers in the chart? It's sorted alphabetically by default lol.

At around $110/MWh, according to the article. This is about 50% higher than what utility-scale PV or wind would cost. Guess they're using OpenAI accounting.

Running a data center on unreliable energy would be shockingly stupid. And unreliable energy sources routinely exclude the wildly uneconomical costs and environmental impact it would take to make them reliable.

Nuclear power plants go down for an entire month at a time for refueling.

Sure - at scheduled, predictable times. That matters.

How much would it cost to build a new reactor with comparable power output?

There's not much to go off of on this subject in the US - only two successful reactor projects have been started since the 70s: Units 3 and 4 at Vogtle in Georgia*. They cost $15 billion each and bankrupted the remnants of Westinghouse (in combination with a similar project in South Carolina which was never finished). *Many reactors started construction in the 70s and were finished in the 80s or 90s, plus Watts Bar U…

The main problem is that things cost more per unit if you do them less. The first new reactor in decades is going to be stupid expensive because you have new people doing it who are learning things for the first time, which often means doing them over again, which is expensive. And then we didn't even get to see if the second unit at Vogtle could improve on the first because then COVID hit and made everything cost even more.

Whereas the interesting question is, how much do they each cost if you build them at scale?

I wonder what the legal basis of the loan is. Congress controls the money; what authorization does the executive branch have for loaning $1 billion?

Learn all about it from the guy who ran the office in the last administration!

Do you have any idea how little Uranium reactors use? And in any case Australia host a LOT of uranium and is a very close ally and is happy to sell it to the US.

And we're even happier if you keep it!

I imagine data centers make the best economic sense when they can run full tilt 24/7. You’ll double your payoff time if you can only run work when the sun shines.

In most parts of the country, solar plus batteries to get through 24 hours will be cheaper than $110/MWh.

Do you have a source for that, when i googled it came up closer to $200/MWh for new york, but that was from older sources. The only thing i saw approaching this price point was if you were somewhere like las vegas.

I also think you would need more than 24 hours battery. You have to prepare for freak weather events that reduce system capacity.

I also wonder what time horizon we are talking. solar and batteries presumably have to be replaced more often than nuclear.

Nuclear power is reliable 24/7 while wind and solar are not and handling this costs money. Microsoft has said that they have more GPUs than electricity to run them so even at $110/MWh it makes sense for them.

I don't know where this '24/7' stuff comes from; they have maintenance outages like anything else. Refueling takes months every couple years, so you're going to have to "handle this" even with nuclear.
