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.

What's happening with CANDU?
This episode features Joe St. Julian, President of Nuclear at AtkinsRéalis, outlining why Canada may be closer to a new nuclear fleet build than most observers realize. Drawing on his background delivering complex U.S. nuclear megaprojects, St. Julian explains why the recent refurbishment programs at Darlington and Bruce have rebuilt the workforce, supply chain, and execution capability needed for repeatable construction. The conversation explores the Monark concept, the strategy of replicating Darlington to minimize first-of-a-kind risk, and the licensing work required to bring legacy designs into alignment with modern standards.The discussion then turns to export markets and geopolitical strategy, including projects in Romania, Poland, and Asia. St. Julian contrasts Canada’s position, a fully active supply chain without a coordinated national build program, with emerging U.S. efforts to align policy, financing, and deployment around Westinghouse’s AP1000. The episode closes on the central question shaping Canada’s nuclear future, whether the country will mobilize its existing industrial base into a sustained build program or allow that capability to remain underutilized.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

Nuclear Fuel: The Most Sophisticated Industrial Product You've Never Learned About

Nuclear Fuel: The Most Sophisticated Industrial Product You've Never Learned About
Nuclear fuel is nothing like the coal or gas it replaces. Where fossil fuels are destroyed in combustion, nuclear fuel must survive years of continuous fission inside a reactor and come out the other end looking almost exactly as it went in. In this episode, fuel engineer Michael Seely breaks down how uranium dioxide pellets are made, why the fuel rod is one of the most sophisticated manufactured objects in the world, and how an industry that once ran more than half its fleet on leaking fuel pins methodically engineered its way to near-zero failure rates by 2010.We also get into enrichment economics, the bespoke nature of reactor fuel design, the post-Fukushima push toward accident-tolerant and higher-burnup LEU Plus fuel, and why high-assay low-enriched uranium (HALEU), the feedstock required by most advanced reactor concepts, requires 40 kilograms of natural uranium and six times the separative work of conventional fuel just to produce a single kilogram. If you want to understand why nuclear plants are built the way they are, why the water cooled reactor won, and what the fuel supply chain challenge really means for the advanced reactor industry, this is the episode to start with.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
