CANDU: The Truly Modular Reactor w/ Navid Badie

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.
