Hard Lessons with Hot Helium
Manage episode 478525142 series 2690047
This week, we talk High Temperature Gas Reactors, or HTGRs, with a Decouple favorite: reactor designer and nuclear historian Nick Touran (What Is Nuclear | X). From the first conceptual sketch of an HTGR in wartime labs to today’s revival by players like X-energy and China’s fast-moving reactor fleet, we dissect what makes HTGRs unique—both in engineering promise and the difficulties that have long haunted their success. With helium cooling, TRISO fuel, and ambitions beyond electricity into process heat and industrial decarbonization, HTGRs may be poised for a comeback. But will history repeat itself, or finally break the cycle?
