The Gas Turbine: The Final Revelation in Humanity’s Pantheon of Prime Movers (W/ David Helmer)
In this episode, host Decouple sits down with gas‑turbine expert David Helmer to trace the evolution of the gas turbine from its wartime origins to its modern role in aviation and power generation. Helmer explains how the core Brayton cycle has remained unchanged while advances in materials—super‑alloys, ceramic coatings, and matrix composites—have pushed operating temperatures and efficiencies ever higher. He also highlights the engineering challenges of cooling, blade‑out testing, and supply‑chain geopolitics that shape today’s turbine design. The conversation underscores the turbine’s unmatched power‑density, making it the dominant prime mover for high‑speed, high‑altitude flight and increasingly for flexible electricity generation.
Understanding the World's Most Unusual Commodity Cycle
In this episode, Chris interviews Grant Isaac, COO of Cameco, to unpack why uranium is a uniquely atypical commodity—its primary consumers secure fuel years in advance, leaving virtually no in‑year demand. Isaac explains Cameco’s vertically integrated model, spanning mining, milling,...
The Absolute Best Water Reactor: What Happened to the World’s Fastest Constructed Reactor?
In this episode, James Krelnstein and the Decouple team dissect the Advanced Boiling Water Reactor (ABWR), spotlighting Japan’s record‑breaking construction of Kashiwazaki‑Kariwa Units 6 and 7, which were built in just 38 months and at a third of the cost...
What's Happening with CANDU?
In this episode, host Chris interviews Joe Saint-Julian, President of Nuclear at Atkins Realis, to explore the current state and future prospects of Canada’s CANDU nuclear technology. Joe outlines Atkins Realis’s role as the OEM for CANDU, its recent contracts...
Nuclear Fuel: The Most Sophisticated Industrial Product You've Never Learned About
In this episode, host decouple talks with nuclear fuel expert Michael Seeley about the unique nature of nuclear fuel, its manufacturing, and the evolution of fuel reliability. They explain how uranium dioxide pellets and zirconium cladding work together to contain...
A Case Study of Excellence From Canada’s Nuclear Golden Age
In this episode, Chris Keefer interviews Ken Petrunik, a veteran of Canada’s nuclear golden age who led the construction of large CANDU reactors—including the Qinshan Phase III project in China—delivered ahead of schedule and under budget under a fixed‑price EPC contract....
EPR: The Reactor That Tried to Please Everyone and Satisfied No One
In this episode of Decouple, the hosts dissect the European Pressurised Reactor (EPR), showing how its over‑engineered safety philosophy—extreme redundancy and conservative margins—clashed with Western construction capacity, supply‑chain readiness, and project‑management culture, leading to massive delays and cost overruns. They...
