There are technologies that decouple human wellbeing from its ecological impacts. There are politics that enable these technologies.

All About BWRs

All About BWRs

This week, we talk Boiling Water Reactors (BWRs) with James Krellenstein, the CEO of Alva Energy. We dive into the engineering, history, and physics of these reactors, how they differ from other designs, and why the United States may have erred in not choosing the Advanced Boiling Water Reactor (ABWR) instead of the Westinghouse AP-1000 for the Vogtle nuclear power plant. Check out longer show notes, including the BORAX experiment video, on Substack: https://www.decouple.media/p/better-water-reactors For this episode, we’ve included a glossary below to help with unfamiliar terms: • ABWR: Advanced Boiling Water Reactor • ATWS: Anticipated Transient Without Scram • BORAX experiments: Historical experiments testing reactor limits through deliberate failures • BWR: Boiling Water Reactor • COPS: Containment Overpressure Protection System • CRDM: Control Rod Drive Mechanism • ESBWR: Economic Simplified Boiling Water Reactor • FLEX: Diverse and Flexible Coping Strategies (post-Fukushima enhancements) • FOAK: First of a kind • IGSCC: Intergranular Stress Corrosion Cracking • NOAK: N-nth of a kind • NRC: Nuclear Regulatory Commission • NSSS: Nuclear Steam Supply System (N Triple-S) • PRA: Probabilistic Risk Assessment • PWR: Pressurized Water Reactor • RCIC: Reactor Core Isolation Cooling System • RPV: Reactor Pressure Vessel • SLC: Standby Liquid Control System Episode title on podcast players: "Better Water Reactors" Learn more about Alva Energy: https://alvaenergy.io/ 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/rss Website: https://www.decouple.media
The Industrialization Playbook

The Industrialization Playbook

This week, we talk industrial policy. Economist and author Steve Keen joins me to shine light on the present moment by exploring the historical use of tariffs and industrial policy in the development of industrial powers from Britain to China. In his usual style, Keen aims to dismantle the myths of free-market economics, explaining how virtually every successful industrial nation began with protectionist policies. With the US now engaged in a trade war with Canada and other nations under Trump's renewed tariffs, we examine whether such measures can effectively rebuild American industry without the comprehensive industrial policies that powered China's meteoric rise. Hint: Keen believes this simplistic tariff solutions may create more chaos than revival for America's industrial base.

All About Uranium Fuel

All About Uranium Fuel

Today, we talk uranium nuclear fuel. I spoke with MIT's Professor Koroush Shirvan, who rejoins me after our first interview on Small Modular Reactors. Now, we dive into the hidden complexities of nuclear fuels. From early fuel experiments that saw uranium rods turn into spaghetti-like structures under neutron bombardment to the intricate economics shaping the future of fuels like TRISO, Shirvan offers clear insights into the realities behind nuclear power’s remarkable yet challenging fuel technologies. Keep watching to discover how history shaped today's dominant fuel choices, why accident-tolerant innovations are critical, and about the economic realities that could either launch or limit the nuclear renaissance.

Germany's Best Hope for Clean Energy

Germany's Best Hope for Clean Energy

This week, Decouple Germany correspondent Noah Rettberg, a physics laboratory technician and precision machinist, talks about the potential to restart German nuclear reactors. A new analysis from Radiant Energy Group examines Germany's potential to redeploy nuclear power using its existing reactor fleet. Through assessment of recently shuttered reactors, their report suggests Germany could restore up to 13 gigawatts of nuclear power to the European grid within eight years – potentially at much lower costs than new construction. As Germany's electricity imports have risen sharply – from 9 TWh in 2023 to 25 TWh by late 2024 – and its economy faces headwinds, the country's nuclear infrastructure might offer a path forward if the political will appears.

Is Oil the Lifeblood of Civilization?

Is Oil the Lifeblood of Civilization?

Mark Nelson, managing director of Radiant Energy Group, joins Decouple host Chris Keefer for another installation of the Masterclass series: this time on the slippery subject of oil. We zoom from ancient plankton to modern empires to see how a mysterious black liquid birthed from prehistoric seas now powers our civilization, touching on the complex chemistry, geology and history of oil.
