Familiar story: Cost estimate for the first 6 new #nuclear reactors in France up by 40% in three years. And that's 13 years before the first one would be completed (not accounting for delays).
Btw, that €73 billion is in Euros of 2020; better known as €85 billion now.

Seeing the discussion, I’d like to clarify:
This post is not a statement on #nuclear energy. I was responding to the specific article that I shared, where @… reported that tech companies are “using AI to speed up the construction of new nuclear power plants.”
My point is - cutting corners and trying to “speed up” the construction or operation of nuclear power plants can have CATASTROPHIC effects.
Chernobyl was a disaster of mismanagement, cost cutting, and insufficient safety procedures.
I do not trust AI, a technology that is notoriously probabilistic and inconsistent in outputs (and with famously high error rates) to be reliable and competent for a use case where the risks are this high.
I also do not support the mindset of wanting to “speed up” ANY regulatory processes and safety checks when it comes to constructing nuclear power infrastructure.
Licensing is not a “bottleneck” here. It’s a safety prerogative.
(Thanks @… for bringing this to my attention!)
»Tech companies are betting big on nuclear energy to meet AIs massive power demands and they're using that AI to speed up the construction of new nuclear power plants.«
What could possibly go wrong. Trust me, I'm an engineer. 🤦

Now we see why Trump wants AI companies to thrive. There's every chance that AI companies are motivated and committed to "funding" this fusion company.
Just one more stop in the AI "investment circle jerk".

Heute vor 23 Jahren: Am 17. November 2002 kam es in einer Kernbrennstoffanlage für #Uranoxid-Brennstoff in Hyderabad, Indien zu einer Explosion einer Thermosiphon-Verdampfereinheit. 100 Liter Lösung (100g Uran/Liter) wurden dabei im Gebäude freigesetzt.
Nuclear power has no special virtues that could possibly justify overpaying for energy like this. Instead of asking—as so many do—how to make nuclear cheaper and faster after decades of real-world proof that it’s nigh-impossible to do (outside of China), we should be asking—as virtually no one does—why anyone even wants to build them.
My best guess:
"Due to [nuclear's] cost and complexity, it will not provide cheap or low-emission electricity in timeframe or scale that matters as climate change continues to broil an indifferent civilization."

When the UK's new nuclear power plant Hinkley Point C starts to produce power in 2030, its guaranteed 'strike price' will have risen to ~150 £/MWh (170 €/MWh). Average wholesale electricity prices will probably be around half of that, so that's a 50% subsidy.
At an annual production of 25 million MWh (3.2 GW in baseload), I'd say that's £1.9 billion per year in subsidies.

Thermal one-loop self-energy correction for hydrogen-like systems: relativistic approach

arXiv:2512.06828v1 Announce Type: new
Abstract: Within a fully relativistic framework, the one-loop self-energy correction for a bound electron is derived and extended to incorporate the effects of external thermal radiation. In a series of previous works, it was shown that in quantum electrodynamics at finite temperature (QED), the description of effects caused by blackbody radiation can be reduced to using the thermal part of the photon propagator. As a consequence of the non-relativistic approximation in the calculation of the thermal one-loop self-energy correction, well-known quantum-mechanical (QM) phenomena emerge at successive orders: the Stark effect arises at leading order in $\alpha Z$, the Zeeman effect appears in the next-to-leading non-relativistic correction, accompanied by diamagnetic contributions and their relativistic refinements, among other perturbative corrections. The fully relativistic approach used in this work for calculating the SE contribution allows for accurate calculations of the thermal shift of atomic levels, in which all these effects are automatically taken into account. The hydrogen atom serves as the basis for testing a fully relativistic approach to such calculations. Additionally, an analysis is presented of the behavior of the thermal shift caused by the thermal one-loop correction to the self-energy of a bound electron for hydrogen-like ions with an arbitrary nuclear charge $Z$. The significance of these calculations lies in their relevance to contemporary high-precision experiments, where thermal radiation constitutes one of the major contributions to the overall uncertainty budget.

🚀 AI's Energy Crisis?
#AI is exploding, but scaling compute with more data & power is too slow and costly—data centers are building nuclear plants! We need smarter ways to turn energy into intelligence.

The hyperscalers' plans for powering their AI datacentres are mostly nuclear, including investing in small modular reactors.
I'm all for that, as long as they don't externalise all the negatives to governments and leave them (us) holding the bag of deadly waste when the bubble bursts.
That sounds too negative. I am genuinely pro-nuclear energy and look forward to the research, just, I don't trust billionaires.
