Climate Change and Mass Extinctions: A deep time perspective Jun 08, 2024

Show notes

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.

Modularity: Lessons from chemical process engineering May 23, 2024

Show notes

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.

We've Gotta Talk About the Bomb May 14, 2024

Show notes

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: Builder of the World's Greatest Nuclear Fleet May 09, 2024

Show notes

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," how he prepared for the oil crisis that triggered the "all nuclear" Messmer plan, and how he survived an ecoterrorist attack to construct the famous nuclear fleet that now lies underused and underappreciated.

Can France rediscover its greatest engineering hero, who died last year at the age of 101, in time to rescue itself and indeed all of Europe from its energy death spiral?

The Chinese Atom May 08, 2024

Show notes

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.

Renewable Nuclear: All about Breeder Reactors Apr 22, 2024

Show notes

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.

Vogtle part 4: Can Positive Learning Happen Next? Apr 16, 2024

Show notes

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?

A Chat with the Nuclear Barbarian Apr 09, 2024

Show notes

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

Californication of the Grid Mar 30, 2024

Show notes

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

Deep Sea Mining Mar 26, 2024

Show notes

Seaver Wang, oceanographer and co-director of climate and energy at the Breakthrough Institute joins me to unravel controversies surrounding deep sea mining for the polymetallic nodules of the abyssal plains.
