James Krellenstein, co-founder of Alva Energy, explains precisely what happened at the Three Mile Island accident, in which an ordinary reactor trip cascaded into a partial meltdown due primarily to errors in the human-machine interface. Krellenstein discusses how the 1979 incident, despite its severity, actually showed the effectiveness of the “defense in depth” principle and led to significant i...

Koroush Shirvan, an MIT professor and consultant on recent major reports on nuclear economics, sheds light on the hidden costs of small modular reactors. Lower power densities, ballooning containment and reactor vessel sizes, poor economies of scale, and missed opportunities for cost reductions mean that SMRs may not be the panacea for nuclear that many believe them to be.

Jigar Shah, Director of the Loan Programs Office (LPO) at the U.S. Department of Energy, joins me to discuss his office’s latest Pathways to Commercial Liftoff report on nuclear energy. We touch on the state of the American nuclear industry, its surge of policy and private sector support, and outstanding obstacles to tripling nuclear capacity in the United States. In addition to emphasizing the ne...

Fred Stafford, a STEM professional and anonymous energy commentator, discusses the Tennessee Valley Authority's potential to lead a nuclear revival in the United States — that is, if it can overcome the tensions between public and private interests and a looming debt ceiling that threatens to dim its nuclear ambitions.

Jean-Baptiste Fressoz, a French historian of science and technology, challenges our understanding of energy history. He unravels the myth of energy transitions, revealing symbiotic relationships between coal, wood, and oil that have shaped our world in unexpected ways.

Mark P. Mills returns to Decouple to challenge our understanding of energy scarcity and efficiency. In this episode, he unravels the paradox of how pursuing energy efficiency often leads to increased consumption, and explains why he believes our energy resources are functionally limitless. -- Mark P.

Microsoft and nuclear plant owner Constellation have entered into to an unprecedented deal to restart the closed Three Mile Island by 2028 to power its data centres. Microsoft will purchase as much power as possible from its 880 MW reactor over 20 years for prices rumored to be above $100 per MWh. Most famous for its 1979 meltdown, TMI closed in 2019 because of cheap fossil fuels and tech companie...

Korea Hydro and Nuclear Power, is embroiled in a bitter legal dispute with Westinghouse over IP rights and export control obligations. Will this conflict stymie Western nuclear ambitions? Does this legal battle risk ceding the longterm geopolitical alliances intrinsic to nuclear exports in non-aligned countries to Russia and China? What are the motivations and likely outcomes? Phil Chaffee of Nucl...

Tim Freeman, VP of Field Services and Manufacturing at CANDU Energy Inc joins me to discuss the 3rd most widely deployed reactor technology in the world, Canada's Heavy Pressurized Water Reactor the CANDU. Note this conversation was recorded in March of 2024.

Ashley Nunes, a senior research associate at Harvard Law School, joins me to disentangle the hope from the hype in the EV debate.

Robbie Stewart and Enrique Velez-Lopez, the founders of nuclear start up Boston Atomics, join me to discuss the true costs of advanced nuclear design engineering.

Jimmy Fortuna of Enverus takes me on a world tour of oil production by region illuminating the unique geopolitical, technological and political challenges to accessing our most important form of energy.

Aidan Morrison, Director of Energy Research at the Centre for Independent Studies joins me for an update on the Australian nuclear debate which is shaping up to be a core issue in the approaching federal election.

Mark Mills is the executive director of the National Centre for Energy Analytics and author of “The Cloud Revolution” How the Convergence of New Technologies Will Unleash the Next Economic Boom and A Roaring 2020s. Join us as we explore how to power an AI enhanced Cloud network and its implications on the grid and climate politics.

Professor Alex Wellerstein returns for a part two answering questions about the bomb, near misses, command and control and more.

Is overzealous regulation the root cause of the contemporary crisis in deployment of nuclear reactors in the USA? James Krellenstein argues that Nuclear Regulatory Commission critics are trapped in the 1980’s and that the spectre haunting today’s deployments are not primarily regulatory. Due to simplified systems and lower material costs modern NRC approved passive reactors should be cheaper than...

Science journalist Peter Brannen joins me to discuss the kill mechanisms of Earth’s five mass extinctions. Humanity has developed the god like power’s to mimic all of them. From altering the carbon cycle to eutrophication of oceans and to a far lesser degree our asteroid like thermonuclear weapon arsenal.

How should we think about modularity in the nuclear space? Jesse Hubesch joins me to disentangle the much hyped concept of modularity from his perspective as a chemical process engineer.

Historian of science Professor Alex Wellerstein joins me to talk about the sword haunting the ploughshare of the peaceful uses of nuclear energy.

Marcel Boiteux, a shy economist who escaped occupied France to fight the Nazis before working out the theory of electricity pricing for newly-nationalized Electricite de France, rose to become the greatest builder of nuclear power the world has ever seen. Mark Nelson, founder of Radiant Energy Group, explains what forces shaped his mind, his role in the fateful "War of the Nuclear Systems,&qu...

While the west struggles to deliver nuclear plants and dreams about novel reactor technologies China is deploying it all: large LWR, SMR and MSR/HTGR. World Nuclear Association China lead Francois Morin joins me to catch us up on recent developments and trends.

In the early days of nuclear power uranium was thought to be a critically rare mineral. Nuclear engineers sought to solve this problem with a special type of reactor that produced more fissile material than they consume. Nick Touran joins me to discuss and explore the long term sustainability of nuclear power.

The Grand Finale is here. We wrestle with the question of whether nuclear can find its groove and the positive learning rates that have eluded it so frequently. Vogtle unit 4 came in 40% cheaper than unit 3. Can those gains continue downwards? Is Vogtle 5 more likely to follow this cost reduction curve compared to a new AP1000 elsewhere?

Emmet Penney joins me to shoot the breeze and catch up on the whirlwind developments of the last few months.

Fan favourite, Mark Nelson, joins me for an update on California’s soaring electricity prices and worsening grid dysfunction.
