Why are people excited about nuclear power again?

Not to freak you out, I know there's a lot going on, but here's a fairly obvious additional problem on the horizon. The rising cost of electricity. Don't just come from nowhere. We have to use resources to generate it. In the US, the electric grid is mostly powered by coal and natural gas. And lately, for the first time in 20 years, our demand for that electricity has been spiking. Some of that spikes.

Driven by AI and data centers. They're often the villains of the story. But it's actually not just them. It's also from a lot of things that everybody actually wants: more electric vehicles, more induction. More factories that have been electrified, hooking up to the grid instead of directly burning fossil fuels for power. The spike in demand isn't just raising the price.

electricity is also generating more emissions. Since even an electric car running on electricity, that electricity is generated in part by burning fossil fuels. problem. And one of the solutions people have started discussing as a way to solve this is actually nuclear power. Nuclear power, which in the 1980s and 90s was kind of a taboo, has become much more popular in recent polling. These days, a majority of Americans, about 60%, are in favor of it.

Some of this is being driven by an understanding that nuclear technology itself has gotten safer, and some of it is just people fear of climate change outweighing or at least reweighing their fear of nuclear disaster. 任何事,Nuclear Power seems to be very much on its way Today in America, nearly 20% of the electricity we use comes from a reactor somewhere. Tomorrow, we'll probably be using much more nuclear power.

What's happened here is that a group of people I was not paying attention to, nuclear optimists, have started to win.

I wanted to hear from these people and learn what they believe. That's our episode this week, along with just a history of nuclear itself. How it was discovered, how society lost faith in it, and what its future might look like here. I want to start with the person I spoke to named Dr. Rachel Slaybaugh. She first encountered nuclear energy back in the early When public sentiment towards it was much more in the world.

Some Navy guy came and talked to us about nuclear reactors and I talked to my high school guidance counselor. I was like, Oh, what about nuclear engineering? They were like, That's a dead field, don't do that. I was like, Okay, great. But in college, I got the opportunity to do a research thing as a freshman. And it was just, you know, you interview some labs and they interview you and you get matched. And I ended up working at the research reactor on campus at Penn State.

Sorry, they have a research reactor. Uh Penn State Grade School, but also great party school. Yep. They they have a they have a nuclear reactor at Penn State. They do. I'm sure there are more STEM-oriented listeners who knew all this already, but Dr. Slaybaugh explained to me that there's about 25 American college campuses, mostly big schools like UT Austin and Kansas State.

Where undergrads fudz around with small nuclear reactors, research reactors, learning how they work. They're not producing significant energy. You can't melt down the quad with them if things go wrong, but they're real reactors. So you're working on a research reactor at Penn State and like What's happening in that room with the research reaction? Yeah. Well I started out in educational outreach. And so I learned all about nuclear energy.

And I was like, wait, a thing the size and shape of a coal plant that doesn't emit air pollution? I was like, why don't we do more of that while these other clean electricity sources have more time to scale up? So for me, I learned about nuclear and I was like, this seems like a very obvious environmental choice. And that's how I got here.

This early time at the reactor would set Rachel on a path. She'd get her PhD in nuclear engineering. She'd then become a tenured professor at Berkeley, then to the federal government, where she'd work for an agency for advanced research projects in energy. These days she's a climate investor at a big firm called DC VC, where she invests in nuclear, among other things. Twenty years spent on every side of this. Academic, public, private.

I asked Rachel, as is the podcaster's privilege, to use her expertise to explain nuclear physics from the 101 level up, starting with this. All nuclear power plants right now run on nuclear fission. What's nuclear fission? So at the base level, fission is when a heavy atom Absorbs a neutron and so the heavy atom is like energetically unstable. And it's so unstable that adding a neutron provides enough energy that it

causes that unstable atom to split into two pieces. And it splits into two new atoms and releases more neutrons when it splits and it releases energy in the form of kinetic energy. Rachel explained that in a nuclear reactor, atoms are split in a controlled chain. The heat this reaction generates then turns water into steam, the steam spins a turbine, and the turbine generates electricity.

To Rachel, the exciting part of all this, when she'd learned about it, is what happens next, or actually what doesn't happen. A nuclear power plant does not emit carbon, just water vapor. This whole process, of course, is nuclear waste, which we'll get into later. But that brief explanation of nuclear fission, how it works. Just that knowledge, once humanity had learned it, was powerful. It contains the seed of everything that would follow. Nuclear weapons, nuclear power, the entire atomic age.

Here is the story of how human beings first figured nuclear energy out. Two scientists worked it out on a walk in the snow over Christmas week. Lise Meitner, who'd fled Nazi Germany that summer, and her nephew Otto Frisch, who'd come to visit her in Sweden. On their walk, they were talking about a letter he gotten from a colleague describing the Strange experiment. She'd been bombarding uranium, like the metal, with new I noticed that something surprising happened.

Neutrons into uranium, he'd ended up with another metal, barium, that's much smaller than uranium. Scientists already knew at the time that uranium was unstable. What Meitner and Frisch worked out on their walk in the snow was that you could actually split a uranium atom in two, and that when you did, it would release energy. Lots of energy. which scratched out these first calculations together out there in the snow. It was nineteen thirty eight.

And it happened to be in the middle of a world war, so that obviously affected the trajectory of this technology. This is writer Rebecca Tuhoos Dubrau. She wrote a book about all this, including the strangeness of how nuclear power happened to have been discovered at the exact moment when our country was willing to use it as a weapon. There was a famous letter that Einstein co-wrote to President Roosevelt. The letter basically said that this phenomenon had been discovered and that

it could be an important source of energy in the future. And then it mentioned that there was also the possibility that it could be used to create a really powerful weapon and that there was reason to believe that Nazi Germany was working toward that. So that was basically the impetus for the Manhattan Project. It was spurred partly by fear that Nazi Germany was working on this and would get there first.

We all know how that story ends. The atomic bomb, the US killing hundreds of thousands of people in Hiroshima and Nagasaki. But after the war, there's this push in America to use nuclear for something besides a weaponry. So pretty soon after the war, there was a lot of excitement about turning to the civilian uses, building reactors.

And there were a few motives for that, I would say. One was interestingly this sort of desire to redeem the horror of the atomic bomb. You might think the reaction would have been. Wow, this is really scary. We should just avoid this kind of technology at all costs. But in fact, it was the opposite. It was like we should really use this in a constructive way.

At United Nations headquarters in New York, United States President Eisenhower arrives to make a proposal for the constructive use of atomic power. had an initiative called Adams for Peace. वालो दालो दालो दालो It gives me great pleasure to present to you the President of the United States of America. So it was in front of the delegates from the United Nations at the UN headquarters in New York. He gives this speech where he kind of reviews the dangers of atomic weapons and the existential Yeah.

The United States stockpile of atomic weapons. Which of course increases daily. Exceeds by many times the total equivalent of the total of all bombs and all shells that came from every plane and every gun in every theater of war. of the years of World War two. But he says, you know, if I just stopped there that would be a tragedy and we have to look to the possibilities from this new technology as well. It is not enough to take this weapon out of the hands of the soldiers.

It must be put into the hands of those who will know how to strip its military casey and adapt it to the arts of peace. And that was kind of the dawn of the nuclear age was what we would now call, I think, techno-optimist, but a very like sharing, let's use energy to pull people out of poverty, let's make this available everywhere.

So at first there wasn't a lot of worry. Generally, the public was on board. There was all this relief that the war was over and excitement about modern prosperity and people were getting all these. budgets and washing machines and dishwashers and I think a general feeling of excitement about modernity in the future. It really was presented quite favorably in the media. As you can see we found ourselves deep in the field of nuclear physics. Of course, we don't pretend to be science.

We're storytellers. There was a Disney program called Our Friend the Adam. And here to tell you the story of our friend the Adam is the author of our book. Dr. Heinz Hauber. This old TV episode viewers would have watched on their sets in 1957 was during the wave of real excitement about our nuclear future. In the clip, Walt Disney himself appears to explain how we're on the precipice of something wonderful, an atomic age.

then hands off to a German scientist holding a storybook, here to tell us in Disney terms about what's going to happen next. As we developed our story of the We made an amazing discovery. We had a science story, but suddenly we realized that it was almost like a fairy tale.

It starts with a man finding a a bottle in the ocean and a genie pops out and basically says that the atom has all of these incredible powers and it has risks, but if we can make it our friends, then we'll have all of these wonders in our lives. That was a very, I think, influential piece of propaganda at the time. That's crazy to imagine like Disney selling It's just so weird that they ended up as part of the um propaganda of this.

I mean the government was deeply involved at every level at in every stage of this. It was subsidizing nuclear power plants in various ways, in part by giving them backup insurance. In the case of accidents. So the government was definitely pushing it pretty hard.

Looking back at the numbers from our era of peak nuclear optimism, roughly the nineteen sixties to the mid seventies, it's just a very different America. The federal government built the first commercial nuclear power plant in the US in nineteen fifty seven in Shippingport, Pennsylvania. But in the 60s, private investment begins to pour in. Slowly at first, Oyster Creek powering parts of Jersey, Dresden One in Illinois, Yankee Row in Massachusetts. Mm.

But it takes off because in the sixties, America's electricity needs were skyrocketing. Nuclear is part of the solution. The big cost was building the plants themselves, but interest rates were low that decade. Great time to finance construction. By the late 60s, U.S. utilities had ordered over fifty new nuclear reactors.

In the next decade, they would order another one hundred and ninety-six. Everyone thought this was just the beginning. The federal government forecast that by the year two thousand, roughly half our grid would be nuclear powered. There would be one thousand nuclear reactors in America. Of course that's not what happened. Here's Rachel. You know, it's an interesting thing'cause the turn sort of happened before the accidents.

It was like a little bit happening in combination. Like there was sort of conservation in the oil shock. So energy growth really shifted, right? We were growing and then uh conservation became more important and we stopped growing in energy as much. And I'm gonna have a a pretty US perspective here. The United States

Instead of building like one product we're gonna build over and over again and get really good at, every reactor was a little bit different from every other reactor. So like reactors never got cheap because everyone was a special snowflake. And so you kinda have these reactors that are just getting more expensive. And then in the eighties you have super high interest rates. And so

Now you can't afford to build one of these projects. So electricity demand is flattening, interest rates are really high, these projects have gotten out of control and expense. And so of course we're not gonna build any new nuclear reactors. So wait, so before there's sort of public catastrophes, the problem is the upfront cost of building a reactor is really high. And so if electricity costs aren't high, and because the reactors themselves hadn't been getting cheaper,'cause people were sort of

building a different mousetrap every time. The sort of public energy was against it, not so much because people were scared, but because it's like those are really expensive to build and we don't need them. Yeah. And then the environmentalist movement in the 70s was kind of anti-energy overall because they felt like having more energy was going to do damage to the environment. And what was their theory for like why did they think more energy w was necessarily bad than

You know, it was really like an environmentalist utopia like we just want to return to the earth kind of a thing. So we just don't want it to be too easy for people to develop. And it was really this idea of like we should just use less of everything. So you had higher interest rates on construction, but really what you had were environmental activists who were beginning to change the public's mind.

In the 70s, nuclear sentiment was beginning to soften. What was really taking off was the idea that you would not want a nuclear power plant in your backyard. Folk musicians were getting very into this. There were no nukes concerts. And then this movie comes out. hit nuclear disaster film in 1979 called The China Syndrome. Clearly people were not that excited about nuclear if you have this nuclear meltdown disaster movie. And I I haven't watched it for how long am I twenty years?

But basically there's a reactor that melts down and then they try to cover it up. But the the reason it's called China syndrome is they're like, uh, this plant is gonna keep melting down and the reaction's running away and it's gonna melt all the way through the earth to China. If the core is exposed, for whatever reason, the fuel heats beyond core.

In a matter of minutes, nothing can stop it. And it melts right down through the bottom of the plant, theoretically, to China. But of course, Which is not how nuclear meltdowns work, by the way. But so they were saying that the radioactive material would burn through the earth, like when you're a kid and your parents say you can take a hold of China. Yeah. That seems wrong.

It it is not correct. And then I would say the nail in the coffin was Three Mile Island that happened like a couple of weeks or ten days or something after that movie came out. For many years there has been a vigorous debate in this country about the safety of the nation's 72 nuclear energy power plants. That debate is likely to be intensified because of what happened early this morning at a nuclear power plant in Pennsylvania. Max? March twenty eighth, nineteen seventy nine in Pennsylvania.

Alan. It's the middle of the night and something's gone wrong. At about four o'clock this morning, two water pumps that help cool reactor number two shut down. Backup systems come online to fix the problem. Except now there's some valve that's supposed to close and it doesn't. Officials say some fifty to sixty thousand gallons of radioactive water escaped into the

Coolant is pouring out of the reactor. The risk obviously is overheating, that the nuclear fuel rods could melt down. The human operators are getting bad information from their gauges. They mistakenly think the reactor is getting too much coolant water. So they cut the water back further. That system down there was no way to draw heat out of the cooling water that circulates through the reactor itself. Again.

The fuel rods do start to melt. About half the reactor core will melt before anyone correctly diagnoses the problem. When fuel rods melt, they release radioactive isotopes you would not want to ingest. And the molten fuel itself turns into a dangerous sludge called corium, nuclear lava. You would not want to be anywhere near it. Amen. This is the point where everyone's in danger. This is the nightmare scenario. Except at Three Mile Island, the quarium was successfully contained.

pooled within the vessel that was meant to hold it in the disaster. Nobody died. And the radiation that was released was small enough that long-term studies have not found clear evidence of health effects in the people who lived by the plant. The facts of Three Mile Island offer a story really about the airbag deploying, the seatbelt working. But that's not how the story of Three Mile Island was metabolized by the American public.

Seven years later, of course, there'd be a real deadly nuclear disaster in the Soviet Union, Chernobyl. But America had turned on nuclear before that. And Dr. Slaybaugh thinks part of the reason really was this movie, The China Syndrome. People treated it almost like a documentary. And so like you've just watched this movie and then there is a meltdown, like you Yeah, and nuclear in particular is like

It's both super complicated, kind of hard to picture outside of most of my nuclear reactor reference or are pop culture. And then when it breaks, it's so visceral. And so the way it shows up in your imagination and the way it shows up on a graph are just very divergent. There's a bunch of things here, but i if you look at what are the factors that go into human threat perception. Our threat perception was not designed for big companies.

Systems. Right? It was designed for like hunting animals. And so things that distort the level of threat we perceive for something is those kinds. So if you think about, okay, it's way more dangerous to drive than fly, but people are afraid to fly. and they're not afraid to drive. It's that same thing, but like even more intense.

it feels like it has grave consequences, like one car accident is, you know, a few people, but a plane crash is a lot of people, it feels like a big consequence. And even if the nuclear consequences actually aren't that high. The news coverage leads us to think something else. So Three Mile Island is an interesting example where no one was actually harmed by radiation in Three Mile Island. Zero. But it felt so scary and you know, people were evacuating and

There was a lot of m misinformation. And so the increase of h stress related health effects in the Harrisburg area went up. So there were real health impacts, but it was because of fear, not because of radiation. It's so strange that part of solving the energy problem is about solving a problem of human psychology. Yeah. The problem only got harder to solve a few years later, of course, with Chernobyl. Somewhere around 30 immediate deaths, thousands more expected in the long term from cancer.

Of course, the plant at Chernobyl had insane design problems you would not find in an American nuclear plant. For instance, the Soviet reactor was a kind of design where if it started to overheat, the reaction would actually speed up, not slow down, like in an American. Just a rundown late Soviet experiment. But for many Americans, this kind of mental composite image formed. Three Mile Island, Chernobyl, atomic bombs, movies about nuclear death, nuclear development in America chilled.

Other countries continued to pursue nuclear, although even that cooled down somewhat after the Fukushima meltdown in Japan in 2011. A nine point zero earthquake triggered a tsunami which flooded the reactor's seawall. There was one confirmed death from radiation exposure, but over 2,200 people died in the hurried evacuation away from the plant. In the aftermath of that, countries like Germany wound down their nuclear programs.

Other countries kept going, most notably France, where today 70% of all electricity comes from nuclear. Their carbon footprint per citizen per year is much lower than ours, four and a half tons per person to R fourteen. We just took a different path in America. Nuclear technology is a place where we stopped advancing. After the break, our second age of much more cautious atomic optimism. Remember that search engine Well we have our own show now called Why can't

eat off the kids menu. Is Taylor Swift bigger than Michael Jackson? Is it actually kind of easy to get away with murder? For these answers and more, search No Such Thing with Manny, Noah, and Devin wherever you listen.

Welcome back to the show. During the pandemic was the first time I started to become aware of pro-nuclear sentiment developing on my internet. I saw more people talking about nuclear positively, openly, in a way that seemed sincere, not just like posters slinging unorthodox takes for. Cloud. That's when I looked at public polling and learned that America was just much more gung-ho on this than I'd realized for my bubble.

I asked Dr. Slayba whether she'd felt public sentiment turned pro-nuclear in the last decade. Radically. And in a way that sort of came it kinda came out of nowhere. Like your perceptions it came out of nowhere or like as far as you can tell it really came out of nowhere? Both. I think from in the nuclear industry, it feels like all of a sudden everyone has

It's like, oh, you finally read the data we've been reading is kind of how it feels. And that's not actually what happened. Like a whole bunch of things have changed. Some of it is generational. Like there are fewer old greens out there like pounding the pavement against nuclear.

millennials are largely more interested in nuclear because climate change is really scary and they can, you know, read the numbers and they're like, oh yeah, this thing makes sense. And what has really shifted now is we're back to a world of load growth and we're like, what are we going to do? Yeah. Load growth meeting like the load on the energy system. Yeah, yeah. Uh higher electricity demand.

So, spiking electricity demand is making people want to rapidly spin up more nuclear power. And one way to do that is to actually just take nuclear plants that we're previously shut down and bring them back. It's called recommissioning. Recommissioning old plants is both technically and politically easier than building new ones, so you can get more power faster.

Palisades nuclear plant in Michigan, Dwayne Arnold nuclear plant in Iowa, and the famous one you've heard of, Three Mile Island is also coming back. What I found interesting is that two of those plants are being brought online specifically for tech companies. The power they'll generate has already been sold to Google and to Microsoft.

If you told me in nineteen ninety five that Microsoft would restart Three Mile Island to deal with the rising energy demand partly caused by teenagers using computers to cheat on their homework, I would have had follow up questions. Of course, the next generation of nuclear isn't just recommissioning older plants. People also want to build newer, more high-tech ones, advanced reactors.

There's a few different categories to these reactors, some of them very unlike the nuclear reactors I was used to. I'm going to tell you about them. So some of these advanced reactors fall under a category called generation four reactor. Generation four reactors are designed to be safer than the reactors we have now. Some use different coolant, some might use a different kind of fuel. But the most interesting ones have this slightly hard to explain quality called inherent safety characteristics.

An inherent safety characteristic is one that removes uh a failure mode from the equation altogether. So you're removing a way that something could go wrong. This is a nuclear policy wonk I spoke to named Dr. Adam Stein from the Breakthrough Institute. He was walking me through this idea of redesigning reactors so they have fewer parts that can fail.

You're not adding another safety system to protect something. You're finding something that could go wrong and just totally removing it from the system. Some advanced reactors might not have a pump in the system at all. It could just use physics. to make the fluid flow as it gets hotter or colder on different sides. So then the pump being removed creates inherent safety because the pump nil order can fail if it doesn't exist in the system.

Reactors with inherent safety designs are not theoretical. They exist. Other countries like China and Russia have built them. I've looked at pictures of these. They don't always have the iconic nuclear reactor cooling towers. Instead, they often look like industrial compounds filled with a handful of boxy buildings.

Some of these Gen 4 reactors are expected to be large reactors. These will be the size of the nuclear reactors you're used to, producing a gigawatt or more of electricity. Full size plants meant to replace the kind of nuclear power we have now, just safer and more efficient. No large Gen four reactors exist anywhere in the world today. Russia has a 1.2 gigawatt Gen 4 reactor expected to come online in the 2030s. China is also expected to be a player in this market.

But at least in the US, Rachel doesn't believe that building reactors at this scale seems very feasible. The big reactors, it's just they're expensive and we have not proven we can build them repeatably and cost effectively. And because they're so expensive, there just aren't that many groups with a balance sheet big enough to build one of them. And so they're difficult to finance. The cost of financing is very high.

And generally speaking, like, is America still leading on the technological development for nuclear, or is it happening in other countries? Like, what does that look like? I mean it it depends on what you mean. We are in many, many categories, not just vision, but fission is one of them. We're leading on like the innovation. So development of like idea development, inventing the new things. But Mostly China is leading on actually building the new things and deploying the new things.

And why is that? Some of it is the way that we are structured. We have a lot more capital for early ideas and we have a lot less appetite for sort of like first of a kind plants or second of a kind plants. Things are more expensive here. And it this is true largely also in Western Europe, where We're just not very good at building mega projects of any kind. Like, you know, the Bay Bridge was triple budget, triple schedule. If you add radiation, that doesn't make it any better. Right. And

there are other countries that are actually good at megaprojects. And a lot of that has to do with vertical integration of the construction companies. They don't have subcontractors. They have complete designs before they start building things. They build the same thing over and over again the same way. Whereas we have subcontractors who are suing each other while the project is going on, you know.

And it's not only their projects can be more cost effective because they're better at building mega projects, they also have a government with a much clearer top down mandate that just funds the things they want to happen. In the US, where we don't have a government that builds its own big nuclear megaprojects, some private companies are now aiming at a different approach.

A few nuclear startups have just decided, okay, what if we made nuclear reactors Which leads us to our next category, small modular reactors. Small modular reactors are advanced nuclear power plants that produce anywhere from 50 to 300 megawatts of electricity. Enough electricity to power a big town or a small city.

You can see pictures of them online. They run the gamut. Some just look like small factory buildings. Others have swooping solar roofs. Star Wars architecture. The main thing here though is the size and the modular part of it. The theory is that by building the same thing over and over again to the same specifications in a factory setting, that eventually you can get costs to come.

There was an understanding that one of the main cost drivers for the existing reactors was that you're building almost everything on-site. You're shipping some large components in, but you're basically constructing it like a Lego set on site. So shifting to a smaller size allows you to build a lot more and fully assemble it in a factory setting. The way that most people say this is you're building an airplane instead of an airport.

Meaning small modular reactors are helpful because their design is standardized. So in theory, you can build them more cheaply at scale in a factory. In Wyoming right now, one relatively small nuclear reactor project has broken ground. It's actually a project from Bill Gates' nuclear startup. It's supposed to be online in twenty thirty. These small modular reactors, their size also means we can just slot them in to replace older, non-nuclear power plants that we want to take offline.

say a coal burning plant we want to decommission. But there's another challenge people want to try to use nuclear energy for. What about getting power to extremely remote parts of the world, like a tiny Alaskan village? This brings us to our last category, micro reactors. Micro reactors really are quite micro, small enough to be easily transported wherever they need to go. Picture a rectangular box the size of the shipping container you'd see on the back of a truck, but sleeker.

Microreactors are designed for places that do not currently have grid access. Some of the earliest concepts of micoreactors were aimed at powering very small island or very close to the Arctic Circle communities that currently use small diesel generators and have supply chain problems with the diesel, or their diesel gums up when it gets extremely cold and they have no power. So basically anywhere that you would put a diesel generator is where you would use a micro reactor. Yeah.

And most of those locations are just like not that easy to get to. The logistics of diesel fuel are complicated. Diesel generators are smelly and they make a lot of local air pollution and they're loud. Like d ev diesel generators are not great. So micro reactors are built as a clean solution to the problem of powering remote communities.

In theory, a micoreactor would fit in my backyard in Brooklyn and could power my whole neighborhood. In practice, I don't think anybody's gonna let me do that. Name bees. However, Rachel says there are a lot of other possible use cases for a micro reactor. As EVs expand and we need EV charging stations kind of in the middle of nowhere, you can imagine applications like, oh, it's probably easier to build a micoreactor than transmission.

Is there a world where in 25 years I'm like, I'm going on a camping trip? I'm gonna go to Walmart and buy a nuclear generator for the trip? I think probably not. I think by then it might be you're going on a camping trip and you have like your EV power station and maybe you plug it into a nuclear charging station somewhere or maybe you have solar panels with you. So what I should picture is

I'm gonna plug the same plug into the same things, but more nuclear might be on the other end of the plug. Yeah. So that's the dream that Rachel and Adam have, but they're nuclear optimists. So let's talk about some of the obstacles here.

The big ones, the ones you do a whole other story on, are just cost and speed. Can we actually make new plants without years and years of expensive delays and cost overruns? The pessimists say no, that solar plus batteries is already cheaper and getting cheaper still. The optimists point out that renewables can't provide the round the clock firm power data centers need. But even the optimists concede that for this to work, they'll need to surmount some real obstacles. A big one, regulation.

Over the past half century, for both understandable reasons as well as frankly political overreaction, we've added a mountain of regulation and bureaucracy and licensing requirements that make building nuclear in America very hard and very slow. Particularly if you want to build a reactor that is a novel design, since novel designs need novel regulations to test their safety.

So to license a newer advanced reactor design that generally uses slightly different fuel or slightly different coolant fluids. they needed to seek exemptions and prove to the regulator why this change is acceptable, it's safe, it's necessary. And this made the regulatory process very cumbersome. Congress has been trying to get the Nuclear Regulatory Commission to speed up its regulatory review for many years. Well thank you very much. We have a very big announcement today and has to do with

Nuclear, energy and other things. And uh this is all nuclear it's uh Hot industry, it's a brilliant industry. Right. The recent executive orders from last year said the NRC has to get applications reviewed within eighteen months. Well, thank you, President Trump. This is a huge day for the Mukaba Industry. Uh mark this day on your calendar. Uh this is gonna turn the clock back on over fifty years of over regulation of an industry. Uh America Always American Green.

Our president, when he's not putting his face on US passports or demolishing parts of the White House or starting wars like a child, have focused on a game of risk. Sometimes he tries to make nuclear regulation work a little faster. If your uncle challenges you to say one nice thing about the administration at Thanksgiving, there you go. But there's another obstacle besides regulation. It has to do with nuclear fuel.

So here's a question I never asked myself. Where, historically, has the United States gotten much of its enriched uranium for its existing nuclear power plant? Well, it turns out from a country that we do not have a totally consistently tranquil working relationship with, Russia. Bill Clinton struck an unusual deal with Boris Yeltsin back in the day. Nine months ago. President Yeltsin and I met in Vancouver. and suddenly And there we laid the foundation for a new partnership.

It was due to drawing down weapons, actually. Second, President Yeltsin and I agreed that as of May thirtieth, I think. The nuclear missiles of Russia and the United States will no longer be targeted against any country. In the megatons to megawatts project. We agreed with Russia that we would draw down our nuclear arsenals With uh US assistance we will continue to process weapons grade uranium into Uh fuel uranium.

And those would be reprocessed essentially into fuel which we used in our reactors in the US to make electricity. We also signed a contract to purchase twelve billion dollars of highly enriched uranium over the next twenty years. So the legacy like post Cold War, all the sort of nuclear material that would have gone into pointing rockets or whatever at each other, we've been basically importing that nuclear material from Russia to fuel reactors.

That material is used up at this point, but we did do that for many years, yes. But it it seems it seems slightly crazy that we were depending on the idea that things would remain good with Russia. Like I understand the idea that countries specialize. But it seems surprising to me that we were not prepared for the idea that like we would have conflict with a country that we often have conflict with.

There had to be some trust in that deal for it ever to work. The bigger concern was drawing down the warheads. Right. And if that could be achieved, then other supply chain risks were essentially considered to be worth it at the time. Of course, 2022, Russia invades Ukraine. Afterwards, Congress votes for an import ban. No more enriched uranium from Russia for us. We lost access to our best uranium connector.

We're rebuilding our domestic enrichment capacity, but these things take time. The final obstacle we're gonna discuss here, one you've probably heard of, nuclear waste. Nuclear waste, the leftover radioactive material from nuclear reactors, is unfortunately radioactive for hundreds of thousands of years. And during that time, it also generates.

Which means essentially you need to find a place where you can bury it very deep underground, in a container that can hold it, and find a local community that's okay being a home for all that. I asked Rachel what her answer is to critics who say that nuclear waste might be just too big a problem to solve. Yeah. How do they feel about waste of other energy technologies and how responsible those other energy technologies need to be for their waste?

Meaning what? Meaning like we're okay with carbon emissions. We're okay with carbon emissions, we're okay with fly ash ponds, not to hate on wind and solar, but there are toxic materials in wind and solar panels that are pretty large in volume. Like nuclear isn't the only technology that produces waste. And the reason nuclear is so interesting is the energy density is so high.

An amount of nuclear fuel the size of a gummy bear is the same as three barrels of oil or one ton of coal. One gummy bear. same amount of electricity as one ton of coal. So it is a real issue that we do need to be responsible for. But we're starting with it's just not that much waste. And the waste isn't like Off in the air somewhere where it's hard to capture, like we know where it is. It's controlled. We're taking care of

day and there are a lot of technical solutions. It is mostly a political problem and I do not want to minimize how s difficult political problems are to solve. Yeah. But the waste can be disposed of or the waste can be recycled. There are a lot of choices. And one of the reasons we have not solved nuclear waste is it's a problem with very low urgency.

This is actually the part of the nuclear optimist's argument that lands least strongly for me. I just I understand why there are people who can tolerate unsafe smog in the air, but not nuclear waste in the ground. At least not near where they live. Even if they've been told by very smart people that the containment technology works. I wouldn't live in that neighborhood. I like poking at a radioactive idea. I would not want to live near radioactive waste. But I was also surprised to learn

There are communities in America where the voters feel otherwise. They trust the science more, or maybe they're willing to tolerate the risk because they know it's not just nuclear waste storage they're agreeing to, but also nuclear jobs and nuclear investment. And there's now some political momentum towards allowing those places to decide for themselves, to become storage sites, if that's what they want.

That's where things stand with nuclear right now. It's safer than we thought it was. The cost and speed of deployment issues are real. The nuclear waste problem is both a technical and a political one.

All those things are real. All of them might not matter much because of the iron fact we opened our story with. Demand. Any energy source you can think of that you might want to use instead of nuclear, environmentally friendly or not, is being recruited for the great data center wars of the mid 2020s. The data centers have already purchased out to 2030 every gas turbine that the world can produce. The interconnection cues for adding new generators to the grid are overflowing. The demand is huge.

Renewables can be part of the solution, but if data centers continue to buy the output of even existing nuclear plants, Then we need to replace that energy for the rest of the market. And if we can't buy new gas turbines because the data center companies have already purchased those.

Then what other option do we have? We have returning retired plants such as coal plants to the market, which is happening in some cases, or building renewables. But nuclear has to be part of that equation if we're going to even Meet this demand curve. And if we don't meet the demand curve, then prices are going to keep going up. So we need to build and we need to build quickly. Dr. Adam Stein of the Breakthrough Institute. We'll have links to his work and to other guests in our show notes.

This story we just played you about nuclear, it's actually part of a very informal series we're going to return to this year. Energy year at Search Engine. Rising electricity costs and all the weird and interesting ways people are trying to solve that problem. We're just really Curious to learn and explore more here.

If you're curious about geothermal, about solar, about the grid itself, we're working on some stories for you. And if you're someone who we can learn from about these topics, please shoot us an email, pjvote85 at gmail.com. Lastly, if you're just confused as to why AI is sucking up so much of our energy supply, please check out our series Colossus. We published it just a little while back. It features the great reporter Shruti.

That's our show this week. I wanted to remind you, Search Engine exists because of a small, generous, and very mighty portion of our listeners who voluntarily pay to keep the show running. Those are the listeners who subscribe to our premium tier, which we call incognito mode. It costs$7 a month, or if you want to discount$50 for the full year.

In exchange, we offer ad-free episodes, some bonus episodes. We've got one coming down the pipe right now, and discounts on our merch. But the real thing you're doing is you're paying money so that we can keep making ambitious work for you. We are currently planning our next season trying to figure out what we're gonna do, trying to figure out how many reporting swings we can really take. And the subscriptions now will help us budget then.

If our show keeps you company while you do errands, if it gives you things to think about, to argue with, to have conversations with the people in your life about, if we have offered you value, please consider doing this. If you're not in a position to do that, don't feel bad. We're just glad to have you as a listener. But if you're interested, you can sign up at searchengine.show. Incognito mode, searchengine.show, 50 bucks a year. All right, Armin, roll the credits.
