The Great Nuclear Reshoring

Decouple ·

2025/11/11

In late October, amid the choreography of President Trump’s visit to Tokyo, two vast and curiously intertwined announcements were made: an $80 billion strategic partnership between the U.S. government and Westinghouse Electric Company, and a $550 billion investment framework between the United States and Japan.This episode of Decouple, hosted by AJ Camacho of Politico and E&E News, brought together Michael Seely, Yuri Humber and Chris Keefer this time in the guest seat to discuss the

2025/10/28

This week I sit back down with François Morin in his third appearance on the show. François is the World Nuclear Association’s point person on China. He works and travels inside China, speaks fluent Mandarin, and spends time at the conventional and advanced reactor sites that the rest of us argue about on Twitter. We cover how quickly China is really building nuclear power compared to the heyday of the French Mesmer plan, how that compares to Chinese coal and gas deployment, why Chinese nuclear is

Engineering State v. Lawyerly Society

Decouple ·

2025/10/21

This week on Decouple, I sit down with Dan Wang, a research fellow at Stanford’s Hoover History Lab and author of "Breakneck: China’s Quest to Engineer the Future." We trace how China became an “engineering state” while America turned into a “lawyerly society,” and what that means for infrastructure, energy, industry, birthrates, social security, and human lives. From Guizhou’s skyways to Jane Jacobs’ shadow over North American cities, Wang shows the upside of abundant state capacity and

2025/10/14

This week, we zoom out to the broader intellectual themes that shaped Decouple’s origins five years ago. I’m joined by Jesse Ausubel, a visionary in sustainability and biodiversity research and the Director of the Program for the Human Environment at The Rockefeller University in New York City. In his long career, Ausubel pioneered the modern study of decarbonization and dematerialization in the late 1980s and early 1990s. He helped organize the first UN World Climate Conference in 1979 and spent

2025/10/06

Process heat accounts for two-thirds of industrial emissions. Yet talk of decarbonization often misses the engineering realities that separate viable solutions from expensive dead ends. To understand process heat and the technologies capable of providing it, I’m joined by returning guest Jesse Huebsch, a process engineer specializing in chemical plants. Our conversation ranges from steel and cement to plastics and ammonia, examining which processes can be electrified, where steam dominates, and why

2025/09/30

Nuclear has entered its meme stock moment. Last week, Oklo hit a market capitalization of $20.7 billion—more than established nuclear giants BWXT, Curtiss-Wright, and AtkinsRéalis—despite having zero revenue, no NRC design certification, and a rejected license application. In my conversation with returning guest Michael Seely, aka AtomicBlender, we examine this preposterous valuation built on glossy renderings rather than demonstrated readiness. If Rosatom, with 70 years of R&D and thousands of

2025/09/22

This week, award-winning science writer Peter Brannen returns to Decouple to explore the 4.5 billion-year story of carbon dioxide on Earth. Grounding our discussion is his new book, The Story of CO2 Is The Story of Everything. From the alien world of the Hadean eon to humanity's emergence as the "pyromaniac ape," Brannen reveals how this trace gas has shaped every aspect of our planet's evolution, through Snowball Earth, mass extinctions, and the rise of complex life, culminating

To Bomb or Not to Bomb

2025/09/15

Professor Alex Wellerstein returns from the set of WIRED (watch his excellent appearance here) to help me understand the origins of Middle Eastern nuclear programs and where they stand today. From France’s covert assistance to Israel’s bomb program in the 1960s to the mysterious Vela incident over the South Atlantic, Wellerstein shows how nuclear weapons spread through unofficial networks of scientists, spies, and opportunistic allies. We explore Iran’s strategic nuclear hedging, Israel’s policy of

2025/09/08

This week, we talk about rare earth metals. What are they, where do they come from, and how are they redefining global power? I’m joined by David Abraham, a natural resource strategist who saw the future of rare earths in 2010 while working in Japan's Ministry of Economy, Trade and Industry. When China cut off rare earth exports over a territorial dispute, Abraham realized these obscure elements, sprinkled into our steel, the magnets in our speakers, the phosphors in our screens, held more

This week, we talk about the rise of the global battery industry: its history, key players, raw material struggles, and how China came to dominate it. To do so, I’m joined by Henry Sanderson, author of "Volt Rush: The Winners and Losers in the Race to Go Green." We trace the story of electrification from Volta’s early experiments to the supply chains that now shape global power. Sanderson brings decades of reporting to a narrative that reveals China’s industrial strategy, the entrepreneurs

2025/08/18

This week, we talk about Russian nuclear exports. Michael Seely, host of AtomicBlender, joins me to discuss the rise of Rosatom: Russia’s nuclear energy behemoth that now builds nearly half of the world’s new reactors. We trace its formation after the Soviet collapse, its grip on the nuclear fuel market, and its unmatched “turnkey” model for newcomer nations. Rosatom’s nuclear exports are more than just a commercial endeavour—they can reshape global influence for decades.Michael's videos on

2025/08/12

This week, we travel to the edge of the map with Aleksandr Surtcev, an engineer who has crewed Russian nuclear icebreakers along the Northern Sea Route. We explore how Russia’s Arctic fleet keeps this strategic corridor open, why floating nuclear plants are powering remote communities and mines, and what life looks like in a place where polar bears trail ships for fish and resupply markets pop up on the ice. Beneath the stories lies a deeper discussion of geopolitics, engineering, and the hard

2025/07/28

This week, Mark Nelson joins us to deliver his second annual “State of the Atom” address. The nuclear power landscape has transformed in the last two years. Russia continues its nuclear export dominance while the West at last awakens from its stupor, driven by an unexpected force: artificial intelligence's insatiable appetite for baseload power. From Amazon's billion-dollar Susquehanna deal to Three Mile Island's resurrection, Big Tech is discovering what nuclear advocates have long

This week, we talk solar power—a long overdue topic on Decouple. In the past, guests have often been critical of the value of renewables on grids without extensive storage, and of the quality of jobs that politicians often claim when justifying renewables programs. Today, however, we drop preconceptions and get to the nuts and bolts. My guest is Seaver Wang, director of the Climate and Energy Research Program at The Breakthrough Institute. Despite is imperfections, the solar power has a remarkable

2025/07/02

We have an unusual episode today. One, because of its length (1 hour 40 minutes), and two, because I’m the guest. Joined by Aidan Morrison as acting host, I talk about a topic of intense interest to me: the Darlington SMR project in Ontario, Canada. I’ve been critical of this SMR project, which recently received its final investment decision, by calling for a pivot to CANDU reactors at the site.I use this episode to break down all my reasons for being critical, and to concede ground to this bold SMR

2025/06/25

This week, we return to nuclear power. Specifically, nuclear construction and “learning curves.” It is intuitive that doing something over and over makes you better at it. In industry, this means driving down costs and timelines and boosting efficiencies. In many industries, the truth of learning curves is readily apparent. However, in Western nuclear construction it has been largely absent for decades. Robbie Stewart, CTO of Alva Energy, joins me to dissect why the nuclear industry struggles with
