• The Real Stakes of a Saudi Nuclear Deal

  Saudi Arabia burns nearly one million barrels of oil per day to keep its lights on, yet it has cheaper and faster ways to replace this than by building large nuclear reactors. So why is the Kingdom pushing so hard for a civil nuclear deal? This episode walks through the strategic logic that has animated Riyadh’s nuclear ambitions for more than a decade. The answer lies in prestige, industrial capacity, and the latent fuel cycle capabilities that come with a power reactor programme, all set against the backdrop of regional tension with Iran.We look closely at the recent Washington announcement that United States Saudi 123 talks have been “concluded,” the unresolved fight over enrichment rights, and the geopolitical pressure being applied to South Korea to align its nuclear exports with American interests. From the legacy of the Quincy pact to the rivalry between Westinghouse and KEPCO, this conversation unpacks how a simple reactor tender has become one of the most consequential energy and security decisions in the Gulf.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/rssWebsite: https://www.decouple.media

• Microreactors: A Mirage of American Nuclear Innovation?

  In this episode, Chris Keefer speaks with Hadron Energy founder Samuel Gibson, the twenty four year old entrepreneur pursuing a ten megawatt integral pressurized water microreactor through a one point two billion dollar business combination with GigCapital7. Gibson outlines why he believes light water is the fastest licensing path, how he assembled a veteran nuclear team, and why Hadron shifted from a one megawatt concept to a ten megawatt design built around LEU plus fuel, modular plant layouts, and air cooled decay heat removal. Keefer presses on the harder questions: whether factory fabrication can overcome the fixed civil works and regulatory burdens that have crippled previous SMR efforts like NuScale and mPower, what off the shelf really means in a hollowed out US supply chain, and how long refueling cycles, fuel qualification, and decommissioning challenges scale at microreactor size. The conversation becomes a broader test case for whether startup optimism can meaningfully confront the industrial, economic, and physics grounded constraints that define real world nuclear deployment.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

• The AP1000 Masterclass

  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. 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/rssWebsite: https://www.decouple.media

• 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. 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/rssWebsite: https://www.decouple.media

• 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.”
