Canada is once again attempting to build nuclear megaprojects after a long pause, making the experience of people who have actually delivered recent large industrial projects increasingly valuable. Ian McGregor is a veteran Alberta engineer, entrepreneur and industrial project developer who helped conceive and build the $12 billion Northwest Sturgeon Refinery and the Alberta Carbon Trunk Line.In this episode we use that project to explore the realities of megaproject delivery: incomplete engineering, supply-chain delays, labour bottlenecks, cost escalation and the challenge of coordinating thousands of critical components across a vast industrial site.We also dive into the refinery’s near-disastrous gasifier burner failure, where a mission-critical component designed to last thousands of hours failed after just 40, forcing McGregor and a small team of engineers and tradespeople to redesign it themselves. From there the conversation broadens into the economics of nation-building infrastructure, why governments often have to play a role in projects with century-long paybacks, and what Canada’s nuclear revival can learn from one of the country’s most ambitious recent industrial megaprojects.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

Fusion has spent nearly a century as the energy source of the future. In this episode, I’m joined by fusion scientist Gerrit Bruhaug to ask what has actually been achieved, what remains unsolved, and why progress has taken so much longer than the early pioneers expected. We start from first principles, how fusion differs from fission, why the Lawson criterion matters, and how magnetic and inertial confinement take radically different routes to the same goal. Gerrit provides an in-depth analysis of the National Ignition Facility’s breakthrough and why ignition is better understood as fusion’s Chicago Pile moment, rather than the near-term arrival of a commercial power plant.From there we get into the engineering realities behind the headlines: laser efficiency, plasma instabilities, neutron damage, divertor heat loads, tritium breeding and inventory, target manufacturing, parasitic loads, engineering breakeven and the enormous gap between making fusion happen and making cheap electricity.Gerrit also takes us through fusion’s surprisingly long history, from the optimism of the first private laser-fusion startup, KMS Fusion, to today’s new wave of heavily capitalized companies, and explains why the two constraints he watches most closely are tritium inventory and engineering gain.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

Iran’s nuclear program is now more than seven decades old, stretching from the Shah’s ambitious Atoms for Peace-era plans to the Islamic Republic’s pursuit of enrichment, missile capability and nuclear latency. Iran historian Farzan Sabet joins Decouple to explain how energy development, techno-nationalism, the trauma of the Iran–Iraq War and a persistent sense of strategic isolation transformed a civilian nuclear project into an increasingly important national-security instrument.We trace the program through the Shah’s plans for 23,000MW of commercial nuclear power, the revolution, the AQ Khan network, the AMAD weapons effort, the JCPOA and the collapse of Iran’s traditional deterrence architecture. Farzan also examines the extraordinary price Iran has paid: sanctions-related economic damage measured in the hundreds of billions of dollars and, by one estimate, comparable to the economic cost of the Iran–Iraq War, yet with neither substantial nuclear power generation nor a nuclear deterrent to show for it.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

For almost the whole of human history, wood was the main act. It was the fuel that cooked food and smelted iron, the material that framed every house and hull, and the first bulk commodity ever moved at scale over long distances. In this episode Chris Keefer talks with energy analyst Mark Nelson about a material we almost entirely take for granted, starting with a fact hiding in plain sight: the grasping hands, binocular vision, and colour sight that define us were all built by an ancestry lived in the trees. From there the conversation turns to why wood, of all the products of photosynthesis, became civilization's battery, storing a century of sunlight in a form that can be felled and hauled away.That storage came with a hard ceiling, because the energy available to any pre-industrial society was set by its land area multiplied by how fast the sun could regrow a forest. Chris and Mark trace that single constraint through the iron furnaces that each needed a forest standing behind them to the oak fleets that turned a Baltic chokepoint into the 19th century equivalent of the Straits of Hormuz. 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

Why are nuclear power plants so difficult to finance, and who ultimately pays when megaprojects run late or over budget? Chris Keefer is joined by returning guest Michael Seely, The Atomic Blender, for a deep dive into the capital costs, construction risks and financing structures that determine whether nuclear projects move forward or collapse. They examine the troubled European EPR experience at Olkiluoto, Flamanville and Hinkley Point C, where delays and cost overruns repeatedly pushed risk back onto reactor vendors and national governments.The conversation then turns to Sizewell C’s regulated asset-base model, which allows investors to earn returns during construction while shifting more risk onto ratepayers and the British state. Chris and Michael also explore Vogtle, VC Summer, NuScale and UAMPS, asking whether private capital can realistically finance new nuclear construction, why government guarantees remain essential, and whether nuclear power should ultimately be treated less like a merchant investment and more like long-lived public infrastructure.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
