Fan favourite, James Krellenstein, returns for a deep dive into the AP1000. We walk through how its conservative nuclear steam supply system is built from proven Westinghouse and Combustion Engineering lineage, and where its true innovation lies, in a radically passive safety architecture that removes the traditional race against diesel generators during LOCAs and station blackouts. From core makeup tanks and automatic depressurization to canned pumps, the in containment refueling water storage tank, the passive residual heat removal system and a containment that behaves like a heat exchanger, James explains how the AP1000 achieves passive safety and demonstrates the dynamism of the U.S Nuclear Regulatory Commission. This is an unvarnished look at a remarkable nuclear engineering achievement.

The Great Nuclear Reshoring
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 implications of this deal for the United States, Japan and Canada.

Russia’s Maritime Nuclear Fleet: A Glimpse Behind the Curtain
This week on Decouple, I sit down with Aleksey Rezvoi, a veteran maritime nuclear engineer who began his career in the Soviet Union designing third- and fourth-generation submarine and icebreaker reactors before later working in the U.S. nuclear sector.We explore the hidden history and living reality of Russia’s civilian nuclear fleet—a line that began with the icebreaker Lenin in 1959 and continues today with the RITM-200, the world’s only serially produced small modular reactor.From Arctic logistics and reactor design philosophy to advanced fuels and industrial ecosystems, Rezvoi offers a rare insider’s view of what the West misses when it talks about “maritime nuclear.”

How China Builds Reactors So Fast
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 still mostly coastal, and the use case, build times and performance of the so-called “advanced reactors” that China is operating while Western startups are still in the powerpoint phase pitching to investors.Watch the full conversation on YouTube.Listen to Decouple on:• Spotify: https://open.spotify.com/show/6PNr3ml8nEQotWWavE9kQz • Apple Podcasts: https://podcasts.apple.com/us/podcast/decouple/id1516526694?uo=4 • Overcast: https://overcast.fm/itunes1516526694/decouple • Pocket Casts: https://pca.st/ehbfrn44 • RSS: https://anchor.fm/s/23775178/podcast/rss Website: https://www.decouple.media

Engineering State v. Lawyerly Society
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 the dark side of excessive control.Buy Breakneck: https://danwang.co/breakneck/
There are technologies that decouple human well-being from its ecological impacts. There are politics that enable these technologies. Join me as I interview world experts to uncover hope in this time of planetary crisis.
