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.

Former U.S. Secretary of Energy Ernest Moniz joins Decouple to examine the history of Iran’s nuclear program and the negotiations that produced the 2015 Joint Comprehensive Plan of Action. As the agreement’s lead American technical negotiator, Moniz offers a rare inside account of his intensive discussions with Iranian nuclear chief Ali Akbar Salehi, explaining how personal trust helped make an extraordinarily difficult negotiation possible. He details the JCPOA’s restrictions on uranium enrichment and argues that its unprecedented inspection, verification and transparency provisions were even more important than its limits on nuclear technology.
The conversation also explores the origins of Iran’s nuclear ambitions, including the formative impact of the Iran–Iraq War, the country’s former structured weapons program and its subsequent accumulation of uranium enriched to 60 percent. Moniz assesses the consequences of the United States’ 2018 withdrawal from the JCPOA, the limits of military action, the weakening of Iran’s civilian leadership and the increasingly difficult prospects for renewed negotiations. Despite these obstacles, he argues that diplomacy remains the only durable path to resolving Iran’s nuclear program, and potentially the wider challenges posed by its missiles, drones and regional proxies.

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.

In this reactor deep dive, Chris Keefer is joined by Navid Badie, Chief Nuclear Engineer at Candu Energy Inc, to explain the inner workings of the distinctive CANDU reactor. They trace how Canada’s decision to use natural uranium led to heavy-water moderation, horizontal pressure tubes, separate coolant and moderator systems, and the ability to refuel continuously while operating. Navid breaks down the reactor’s fuel channels, steam generators, online fueling machines, and the remarkable operating experience behind a technology that has completed nearly a million online refuelling operations.
The conversation also examines CANDU safety and longevity: large inventories of water, natural thermosiphon cooling during a station blackout, and the engineering behind reactor refurbishment. Chris and Navid discuss pressure-tube metallurgy, robotic inspection and maintenance, cobalt-60 and other isotope production, and why locally manufacturable natural-uranium fuel can offer importing countries greater fuel-cycle sovereignty. A technically grounded introduction to one of the world’s most unusual and capable reactor lineages.
