You’ve probably heard the rumors that nuclear is dead. Between the terrifying headlines from decades ago and the skyrocketing popularity of wind and solar, it’s easy to assume that those massive cooling towers are just relics of a bygone era. But if you look at the data on nuclear power plants in the world right now, the reality is the exact opposite. We are actually entering a "Second Nuclear Age," and it’s looking way different than the first one.
It’s kind of wild.

While countries like Germany have famously pulled the plug on their reactors, others are doubling down. China is building them at a pace that makes your head spin, and even the tech giants in Silicon Valley—think Microsoft and Google—are suddenly obsessed with nuclear because AI eats more electricity than almost anything else on the planet.
Where the Reactors Are (and Where They Aren't)
When you look at the map of nuclear power plants in the world, the geography is shifting fast. For a long time, the U.S. and France were the undisputed heavyweights. And look, the U.S. still technically has the most operable reactors with 94 units. But the momentum has moved East.
According to the International Atomic Energy Agency (IAEA) and the World Nuclear Association, China currently has about 56 reactors in operation but—and this is the kicker—they have over 20 more under construction. They’re basically building a new fleet while the West struggles to get a single project finished on time.
Then you have France. They are the outliers of Europe. They get about 70% of their electricity from nuclear. It’s their backbone. When the rest of Europe was panicking about natural gas prices recently, France was (mostly) sitting pretty, though they've had some maintenance headaches with their aging fleet lately. It's a complicated picture. You have the "old guard" trying to keep the lights on with 40-year-old tech, and the "new players" like the UAE, which recently finished the Barakah plant, proving that you can actually build these things in the desert from scratch if you have the will and the cash.
The Elephant in the Room: Safety and Fear
We have to talk about it. Whenever anyone mentions a nuclear plant, the brain immediately goes to Chernobyl or Fukushima. It’s a visceral reaction.
But if we’re being intellectually honest, the "death per terawatt-hour" metric tells a story that most people find hard to believe. Nuclear is actually one of the safest forms of energy we have—statistically on par with wind and solar and orders of magnitude safer than coal or gas. The problem is that when a coal plant kills people via air pollution, it’s a slow, invisible tragedy. When a nuclear plant has a meltdown, it’s a global news event.
The industry is leaning into "Passive Safety" now. Older plants required pumps and electricity to keep the core cool during an emergency. If the power went out, you had a problem. Newer designs, like the AP1000 or various Small Modular Reactors (SMRs), use gravity and natural convection. If everything fails, the physics of the design itself shuts the reactor down. No human intervention needed. It’s basically "fail-safe" rather than "fail-dangerous."
The Tech Shift: Big vs. Small
The old way of building nuclear power plants in the world was to go big. Gigantic. We’re talking 1,000+ megawatt beasts that take 10 years and 10 billion dollars to build. These are "stick-built" projects, meaning they are constructed on-site like a massive custom mansion.
That model is sort of breaking.
Look at the Vogtle plant in Georgia (USA). It finally got its new reactors online, but it was years late and billions over budget. It’s a miracle of engineering, but it’s a nightmare for an accountant.
This is why everyone is talking about SMRs—Small Modular Reactors.
Imagine a reactor that is made in a factory, like a Boeing jet, and then shipped on a truck or a railcar to the site. Companies like NuScale, TerraPower (backed by Bill Gates), and Kairos Power are betting the farm on this. The idea is simple:
- Make them smaller (under 300 MW).
- Mass-produce the parts to lower costs.
- Plug them into existing grids where old coal plants used to be.
It’s a total vibe shift for the industry. Instead of one massive, terrifying project, you have a series of smaller, manageable ones.
Why Big Tech is Saving Nuclear
This is the part that most people didn't see coming. Five years ago, if you said Microsoft would be the catalyst for a nuclear revival, people would have laughed.
But then came GenAI.
Large language models require an ungodly amount of 24/7 "baseload" power. Wind and solar are great, but the sun sets and the wind stops. Data centers can't just turn off. This has led to some mind-blowing deals recently.
- Constellation Energy is restarting the Unit 1 reactor at Three Mile Island (yes, that Three Mile Island, though the unit that didn't melt down) specifically to power Microsoft data centers.
- Amazon recently bought a data center campus connected directly to the Susquehanna nuclear plant in Pennsylvania.
- Google signed a deal with Kairos Power to deploy a fleet of SMRs.
The tech industry has realized that to hit "Net Zero" while running billions of AI queries, they need nuclear. It’s no longer just a government thing; it’s a business necessity.
The Global Leaders: A Quick Reality Check
If you want to know who is winning the race, look at the "under construction" list.
- China: As mentioned, they are the undisputed kings right now. They use a design called the Hualong One and they are exporting it to places like Pakistan.
- Russia: Rosatom is actually the world's largest exporter of nuclear technology. They are building plants in Egypt, Turkey, and Hungary. Even with all the geopolitical drama, Russia remains a massive player in the global nuclear fuel cycle.
- India: They have a very unique strategy involving thorium because they have tons of it, whereas they lack high-grade uranium. They’re playing the long game.
- The U.S.: We are excellent at keeping our old plants running incredibly efficiently, but we are just now relearning how to build new ones.
The Fuel Problem: It's Not Just About the Building
You can't talk about nuclear power plants in the world without talking about uranium. For a long time, the market was sleepy. Prices were low. Nobody cared.
Now, there’s a scramble.
A lot of the world’s uranium comes from Kazakhstan, Canada, and Australia. But the processing—turning that rock into fuel—is heavily concentrated in Russia. The West is currently in a mad dash to "re-shore" enrichment capabilities. If you have the plant but no fuel, you just have a very expensive concrete dome.
There’s also the waste issue. People always ask: "What about the radioactive waste?"
Honestly? It’s a political problem, not a technical one. All the spent fuel ever produced by U.S. commercial nuclear power could fit on a single football field stacked about 50 feet high. We usually keep it in "dry casks"—big steel and concrete cylinders—on the sites of the plants. Finland is the first country to actually finish a permanent deep geological repository (Onkalo), proving that we can put it underground safely; we just usually lack the political courage to pick a spot.
What This Actually Means for You
So, why does any of this matter to the average person?
Electricity prices are the heartbeat of the economy. In places where nuclear is being phased out without a solid backup, prices tend to spike and the grid gets shaky. In places that embrace it, you get a stable, carbon-free foundation that allows you to add as much wind and solar as you want without worrying about the lights going out on a cloudy day.
The "Nuclear Renaissance" isn't a theory anymore. It’s happening in the form of massive construction sites in China, restarted reactors in Pennsylvania, and "micro-reactors" being designed for military bases and remote mines.
Actionable Insights for Following the Industry
If you want to keep an eye on this space without getting bogged down in the jargon, here is what you should actually watch:
- Watch the "First of a Kind" (FOAK) SMR projects. If NuScale or TerraPower can actually get their first commercial units online without a 200% budget overrun, the floodgates will open. That is the "make or break" moment for the next decade.
- Monitor the Uranium Spot Price. This is a leading indicator. When the price of uranium goes up, it means utilities are panicked about long-term supply for their fleets.
- Look at the "Life Extensions." Most nuclear power plants in the world were originally licensed for 40 years. Many are now being cleared for 60 or even 80 years. Every time a plant gets an extension, it’s basically like getting a massive, carbon-free power plant for free because the construction costs were paid off decades ago.
- Follow the "Grid Connection" reports. Don't listen to what politicians say; look at what is actually being plugged into the grid. The IAEA’s Power Reactor Information System (PRIS) is the "gold standard" database for seeing what’s actually turning on and off.
Nuclear energy is polarizing, sure. It’s expensive to start, it’s scary to some, and it takes forever to build. But as the world gets hungrier for power and more desperate to cut carbon, the big cooling towers aren't going anywhere. In fact, we're probably going to see a lot more of them.

The transition is messy. It’s not a straight line. But the global shift toward a high-energy, low-carbon future almost certainly runs right through the heart of a nuclear reactor. Check the construction permits in Asia if you don't believe me—the numbers don't lie.
